RTA SERIES II

RÉAMHRÁ

Is uirlis tomhais fuaime é anailíseoir fuaime fíor-ama (RTA) a thaispeánann dhá chineál faisnéise go grafach:

1. The frequency response of an audio system or device, and
2. The frequency response of the listening environment.

Tá an cineál seo faisnéise an-úsáideach chun córas PA a chothromú, spotaí te aiseolais, nó “nóid”, a aimsiú i gcásanna athneartaithe, agus freagairt minicíochta trealaimh fuaime eile a chothromú.
RTAs that show both the entire audible frequency spectrum (20 Hz to 20 kHz) and its entire dynamic range (loudness from 0 dB to 120 dB) are called spec-trum analyzers. RTAs that show portions of the dynamic range are called “window” RTAs.

FAOI RTA AN DOD
Is RTA de chineál fuinneoige é Sraith II RTA DOD Electronics. Clúdaíonn sé an speictream minicíochta inchloiste (20 Hz go 20 kHz), agus tá méadar leibhéal cúig LED aige do gach ceann de na 31 banda minicíochta fuaime a chlúdaíonn sé.
Tá micreafón tomhais fuaime calabraithe san áireamh sa RTA Series II. Tá cábla 40 troigh ar an micreafón seo a chuireann ar do chumas an micreafón a shuíomh i roinnt áiteanna sa limistéar athneartaithe agus tú ag déanamh do mheasúnuithe ar an gcóras fuaime. NÍOR CHÓIR ACH AN MICREAFÓN SEO A BHEITH BREISEÁILTE ISTEACH SA SEAC AR THOSAIGH PAINÉIL AN RTA. D’fhéadfadh micreafóin eile a bheith damáistithe nó léamha míchruinne a thabhairt.
Is féidir íogaireacht an RTA a mhodhnú ag baint úsáide as an rialú leibhéal ionchuir, agus is féidir fuinneog an RTA a leathnú nó a chúngú ag baint úsáide as an lasc Rún. Ligeann an lasc seo duit raon taispeána an LED a roghnú i dB in aghaidh an LED. Is féidir leat céim 1 dB in aghaidh an LED (le haghaidh fuinneog 4 dB ar leithead) nó céim 3 dB in aghaidh an LED (le haghaidh fuinneog 12 dB ar leithead) a roghnú.

The DOD RTA Series II also has its own internal pink noise generator and level control. Pink noise is defined as an audio signal that contains all frequencies at equal energy levels. For this reason, pink noise sounds a lot like static. Pink noise is useful when setting up P.A. systems and audio systems when you need to see the frequency response of the system.

Ar chúl an aonaid tá seac micreafóin chúnta le húsáid le micreafóin tomhais eile, agus seac aschuir don ghineadóir torainn bándearg. Nuair a bhíonn an torann bándearg múchta, feidhmíonn an seac seo mar aschur fuaime ionas gur féidir an comhartha a lúbadh tríd an RTA agus monatóireacht a dhéanamh air le linn taibhithe. Tá seac ionchuir ann freisin a ligeann duit trealamh i gcóras a anailísiú go díreach.

RIALUITHE PANEL FRONT

• Athraigh Cumhacht: Applies power to the RTA.
• Taispeáin LEDs: Each vertical column of LEDs displays the signal level within that frequency band. Each frequency is on a 1/3rd octave ISO centered point from 20 Hz to 20kHz.
• Rialú Leibhéil Ionchuir: This control sets the input level from the calibrated microphone input jack, the line level input jack, or the auxiliary microphone input jack. Use this control to set the response of the display to a useful range.
• Athraigh Rún: This push-push switch selects the size of step between LEDs to either 1 dB or 3 dB. This effectively widens or narrows the window that the RTA shows, giving you a wider or narrower view of the incoming sig-nal.
• Pink Noise Switch: This push-push switch turns the pink noise generator on or off. To prevent damage to your audio system, be sure to turn down your audio system’s gain control before turing on the pink noise generator.
• Pink Noise Level Control: This rotary potentiometer sets the output level of the pink noise generator. To prevent damage to your audio system, be sure to set this control to minimum before turning on the pink noise generator.
• Calibrated Microphone Input Jack: This jack supplies power to the calibrat-ed microphone. Plug only the calibrated microphone provided with the RTA into the jack on the front panel of the RTA. Other microphones may be dam-aged or give inaccurate readings.

RIALUITHE PANEL CEANN

Auxiliary Microphone Input Jack: A female XLR-type connector intended for use with microphones other than the calibrated microphone provided with theRTA. This jack accepts low impedance microphones.

• Line Input Jack: This is a 1/4-inch phone jack that may be connected to unbalanced line level sources.
• Line Output/Pink Noise Output Jack: A 1/4-inch phone jack that provides connection to unbalanced line level inputs. Engaging the pink noise switch on the front panel causes the pink noise generated by the RTA to be output through this jack. Adjust the level for the pink noise generator with the rotary potentiometer on the front panel of the RTA. Disengaging the pink noise switch on the front panel allows this jack to act as a pass-through to the sig-nal introduced at the line input jack.

NÓTAÍ IARRATAIS
Seo roinnt smaointe tábhachtacha le tuiscint sula n-úsáideann tú an RTA.
Is gléas tomhais é an RTA. Ní dhéanann sé difear don fhuaim ná ní athraíonn sé í. Chun na hathruithe riachtanacha a dhéanamh ar fhreagairt minicíochta i gcóras fuaime, beidh cothromóir grafach nó cothromóir paraiméadrach ag teastáil uait. Ós rud é go dtomhaiseann an RTA i méaduithe 1/3ú ochtach, is fusa cothromóir grafach 1/3ú ochtach a úsáid sa chóras, amhail 231 Sraith II, 431 Sraith II, nó 831 Sraith II de chuid DOD.
Tá cothromóir paraiméadrach úsáideach freisin. Níl cothromóirí paraiméadracha chomh héasca le húsáid agus atá cothromóirí grafacha, áfach.

Nóta: A lot of “fixing” can be done by simply repositioning the microphones and speakers in a system.
Cabhróidh an RTA leat fadhbanna freagartha minicíochta a aimsiú i do chóras fuaime, agus, ag baint úsáide as cothromóir, na fadhbanna sin a cheartú. Tosaíonn an fhuaim taitneamhach tar éis duit na fadhbanna córais a cheartú, agus is fearr é sin a dhéanamh ag cluas a bhfuil taithí aige. Beidh córais “cothroma” ró-ghéar nó ró-gheal don éisteoir i bhformhór na gcásanna athneartaithe, mar sin athróidh socrú an chothromóra beagnach i gcónaí chun an córas a dhéanamh níos fearr.
When measuring the sound in an enclosed sound reinforcement application, use more than one microphone location. This is because speaker dispersion characteristics vary greatly as you move around the room (particularly with multiple driver systems). If you find that different areas of the room behave differently, try to average the settings on the equalizer to correct the room as a whole.

Ní gá duit an córas a phléascadh le torann bándearg. Bain úsáid as leibhéal sách ard ón RTA chun aon torann comhthimpeallach seomra (amhail oiriúntóirí aeir nó torann tráchta) a shárú. Ba chóir go mbeadh íogaireacht an RTA ard go leor ionas nach lasann an torann sa seomra aon cheann de na soilse LED nuair a mhúchann tú an torann bándearg.
Bain úsáid as an socrú taifigh 3 dB ar mhinicíochtaí faoi bhun 500 Hz. Is cúis le buaicfhreagairt an torainn bhándearg claonadh sa socrú taifigh 1 dB, rud a fhágann go bhfuil sé deacair é a cheartú go tapa. Bain úsáid as an socrú taifigh 1 dB chun minicíochtaí os cionn 500 Hz a thomhas.

COMHIONANNÚ PRÍOMHCHAINTEOIRÍ CÓRAIS ATHNEISTE CAIGHDEÁNACH
Ar dtús, cuir an micreafón calabraithe 3 go 4 throigh os comhair na bpríomhchainteoirí ar ais an chainteora. Tá sé seo thar a bheith tábhachtach le córas faoi dhíon ionas go ndéanfaidh tú na chéad choigeartuithe ar an gcóras laistigh den achar criticiúil seo (sula mbíonn deis ag macalla thimpeallacht an tseomra difear a dhéanamh do fhreagairt an chórais).
Cas an gineadóir torainn bhándearg air, agus bí cúramach gan an córas a phléascadh. Déan cinnte go laghdaíonn tú an t-ionchur chuig an gcóras, ansin méadaigh leibhéal an torainn bhándearg go leibhéal tomhaiste in-éisteachta. Ag baint úsáide as an gcothromóir grafach, coigeartaigh freagairt an chórais le bheith chomh cothrom agus is féidir.
Nuair a bheidh an córas cothromaithe agus ceartaithe agat sa réimse gar, bog an micreafón calabraithe amach sa seomra, achar éisteachta gnáth ó na cainteoirí. De réir mar a bhogann tú an micreafón ar shiúl ó na cainteoirí, tabharfaidh tú faoi deara dhá rud:

1. The high frequency response of the system will fall off, usually starting at about 10 kHz.
2. When there are other structures nearby, one or more peaks or dips will appear in the low end.

The high frequency roll off is caused by absorption of high frequencies in the air. Don’t adjust the highs any more by measurement. The highs can be adjusted by ear using program material you’re familiar with. Be sure to check several positions in the room and compromise the equalization/attenuation setting for the best possible sound. This may be done either with the equalizer or by aiming the tweeters of the main speakers differently.

Baineann ísliú agus buaicphointí minicíochta ísle leis an seomra, agus is féidir iad a cheartú go pointe áirithe. Sula ndéanann tú aon cheartúcháin, bí cinnte an micreafón calabraithe a bhogadh timpeall an tseomra chun tuiscint a fháil ar cé chomh spleách is atá na buaicphointí agus na hísliú ar a suíomh. Nuair a bheidh a fhios agat cá bhfuil na buaicphointí sa seomra, ag na minicíochtaí a tharlaíonn siad, agus a n-éifeachtaí. amplitude, féadfaidh tú iarracht a dhéanamh iad a bhaint amach leis an gcothromóir.
Finally, play some program material with which you’re familiar and set the sys-tem’s response to your taste.

AG COMHIONNÚ STAGMONATÓIRÍ E AG ÚSÁID AN RTA

• Is bealach tapa agus éasca é an nós imeachta seo a leanas chun aiseolas i gcóras monatóireachta a íoslaghdú, agus an fhuaim is fearr a fháil ó do chóras monatóireachta.tagmonatóirí e. Cuir an micreafón calabraithe cúpla orlach ar thaobh an stage micreafón.
• This is so that the stagNí chuireann an micreafón isteach ar an micreafón calabraithe agus é ag piocadh suas an stagcomhartha monatóireachta e.
• Turn on the pink noise generator, being careful not to blast the monitors. Make sure that you turn down the input to the system, then increase the pink noise level to a convenient measuring level. Use just enough level from the

RTA to overcome any ambient room noise

• Cas suas an gnóthachan ar an stagna micreafóin go dtí go dtosaíonn siad ag tabhairt aiseolas. Feicfidh tú minicíocht an aiseolais ar taispeáint sa fhuinneog RTA.
• Má tá níos mó ná ceann amháin á úsáid agattage monitor, find the one that feeds back the worst and use that monitor to find the feedback nodes. Notch out the offend-ing frequency with your equalizer. Increase the gain on the stage micro-phones until you observe another feedback node. Notch out this frequency.
• Féadfaidh tú iarracht a dhéanamh minicíochtaí eile a aimsiú agus a ghearrthóga amach, ach tar éis an tríú minicíocht, ní bheidh sé seo táirgiúil. Feicfidh tú go laghdaítear cáilíocht fuaime an chórais monatóireachta trí ghearrthóga doimhne a dhéanamh chun an t-aiseolas a laghdú.
• Ag baint úsáide as torann bándearg, déan iarracht freagairt na monatóirí a mhaolú. Más mian leat an leibhéal fuaime is airde is féidir a bhaint amach sula dtagann aiseolas ón stagI gcás monatóirí, laghdófar cáilíocht fuaime an chórais monatóireachta. De ghnáth, faightear an fhuaim is fearr ó na monatóirí le “socrú comhréitigh” ar an gcothromóir. Is é cuspóir an chineáil seo socraithe ná na nóid aiseolais a laghdú go measartha, ach fós cáilíocht fuaime mhaith a cheadú ó na monatóirí.

Another method for equalizing a monitor system uses the stage microphones without the RTA’s calibrated microphone. Most reinforcement type microphones are not flat in their frequency response. This procedure, however, takes the stage microphone’s response into account as you equalize the system.

• Use the system’s own microphones to samplig an réimse fuaime ar stage using the pink noise generator signal. Have someone stand in front of the microphone or place their hand in front of the microphone so that you can see what effect it may have on the system’s feedback and overall sound.
• This is the best way to minimize feedback and get the highest sound level from the monitors, but you will sacrifice some sound quality.
• Once you’ve equalized the system with one of the above procedures, the following setup will help you find the howls and ringing that inevitably occur as you use the system (this procedure can be used for both monitors and mains).
• Use a mono or auxiliary output or loop through the RTA to your speakers.
• Adjust the level input to the RTA so that the “+” LEDs flash on signal peaks. Set the resolution of the RTA to the 3 dB range.
• After feedback occurs, watch the RTA. The last frequency band to decay is where the feedback is occurring. This frequency may then be notched out using the equalizer.

834/835 SERIES 11

RÉAMHRÁ
Is trasnú steirió 834-bhealach, mona 3-bhealach é an DOD 4 Series II, agus is trasnú steirió 835-bhealach, mona 2-bhealach é an 3 Series II. Tá na líonraí trasnú ardchaighdeáin seo deartha chun an caighdeán fuaime is airde a bhaint as do il-ampcóras fuaime ed ar phraghas is féidir le ceoltóirí oibre a íoc.
Coscann scagairí Butterworth 18 dB/ochtach, atá athraitheach ó thaobh stáit de, buaicphointí nó ísliúcháin san aschur ag pointí trasnaithe, rud a chinntíonn cosaint mhaith don tiománaí trí mhinicíochtaí trasnaithe a rolladh amach go tapa.
Is féidir scagaire ardphas dhá phol a chur isteach go leictreonach ag 40 Hz ag baint úsáide as lasc ar an bpainéal tosaigh (834 amháin), agus tá aschur suimithe minicíochta ísle athraitheach ar fáil d’fheidhmchláir fho-fho-fhuaimeora mona.
Tá lipéad soiléir ar phainéal cúil an 834/835 le haghaidh oibriú steiréó agus mona, agus tá lasca céime i ngach aschur ar an 834 seachas an t-aschur Suim Minicíochta Íseal mona.

Is iad na minicíochtaí ísle atá sa chlár a dhéanann na héilimh chumhachta is mó i gcóras fuaime. Tá sé seo amhlaidh toisc go bhfuil faisnéis ísealminicíochta den chuid is mó i gcomharthaí ceoil agus gutha, agus go ginearálta bíonn tiománaithe ísealminicíochta níos lú éifeachtúlachta ná trasduchtóirí ardminicíochta.

D’fhéadfadh sé a bheith níos éasca freisin roinnt córais chumhachta níos lú a iompar ampleictreacha timpeall, seachas ceann mór amháin, rud a fhágann go bhfuil sé níos éasca córais iniompartha a láimhseáil.

SUITEÁIL

Suiteáil an trasnú i raca ag baint úsáide as na scriúnna raca a chuirtear ar fáil. Treoraigh an corda cumhachta AC amach ó na línte fuaime agus breiseán isteach i soicéad áisiúil é. Ceangail línte fuaime leis an trasnú ag baint úsáide as na seacanna ionchuir chuí chuig cainéil 1 agus 2 (le haghaidh oibríochta steirió), nó chuig cainéal 1 amháin (le haghaidh oibríochta mona). Ceangail na seacanna aschuir chuí le haghaidh oibríochta steirió 3-bhealach, mona 4-bhealach (834 amháin), nó steirió 2-bhealach, mona 3-bhealach (835). Tá an painéal cúil marcáilte go soiléir le haghaidh nasc ceart. Lean na lipéid uachtaracha le haghaidh nasc steirió nó na lipéid bun le haghaidh nasc mona.
All inputs and outputs are balanced. Use XLR type male plugs for inputs and female plugs for outputs. For balanced operation using 1/4″ phone plug con-nectors, use only tip-ring-sleeve (stereo) jacks. For unbalanced operation using 1/4″ phone plug connectors, use only tip-sleeve (mono) jacks.

844 SRAITH II

RÉAMHRÁ
The DOD 844 Series II Quad Noise Gate consists of 4 independent noise gates in a single rack space unit. Threshold, release time, and attenuation (0 dB to 90 dB) for each gate are user controllable. Special features include a Key input for gating, or “keying”, from a signal other than the input. A control out-put is also provided for triggering other devices with a 5 volt pulse from the selected channel when the input for that channel rises above the threshold. Monitoring the operation of the 844 is made simple with front panel LEDs that indicate the operating status of each channel (lit when input signal is being gated).

SUITEÁIL
Install the 844 in a rack with the provided rack screws. Route the AC cord away from audio lines to a convenient outlet. Connections to the input and output jacks are made using balanced tip-ring-sleeve or unbalanced 1/4″ tip-sleeve phone plugs.
FOR BALANCED CONNECTION: wire the plug as follows:

• Tip: high.
• Ring: low.
• Sleeve: ground.

DO NEAMHCHOTHROMAITHE CONNECTION: wire the plug as follows:

• Leid: ard.
• muinchille: íseal

IARRATAS
The 844 Series II Quad Noise Gate can be used in a variety of situations. The  most typical use is a standard noise gate. With the Key Source switch set to INT and the Attenuation control set to 90 dB, the unit will attenuate the input signal when its level falls below the threshold level. The release control (fade time) can be set to begin the attenuation very slowly or very quickly as desired.
Is é príomhúsáid geataithe ná torann a bhaint nuair nach mbíonn an comhartha atá ag teastáil i láthair. Feidhmchlár tipiciúil is ea geataíocht a dhéanamh ar an gcic-dhruma i dtrealamh druma le micreafón. Cuirfidh geataíocht deireadh le torann an pheadail sula mbuailtear an druma.

• Ceangail an réamhampaschur micreafóin ardaithe chuig ionchur an 844, agus aschur an 844 a cheangal le hionchur meascthóra.
• Set the Attenuation to 90 dB and set the threshold so that the gate only opens when the drum is struck. Less attenuation may be needed if the effect of the gate is too noticeable.
• Switch the Key Source control to Ext. The detector will now ignore the high frequency signals (in this case, the cymbals), and will allow the drum signal though only when the drum is struck.
• Is féidir úsáid a bhaint as eochracha le haghaidh níos mó ná torann a bhaint amháin. Má tá meaisín druma ceangailte leis an ionchur Eochrach, déanfar an comhartha ag ionchur an chainéil a shioncrónú le comhartha an mheaisín druma.

Le haghaidh example, if the signal appearing at the channel input of the gate is a sus-tained guitar chord, the resulting output would be the chord sound “played” to the rhythm of the drum machine. Using this technique can produce some interesting results. Try using different Key sources to trigger the gate. You may find something you like.
The Control output is a unique feature of the 844 Series II. This output can be used to trigger a drum machine or sequencer in time with whatever is input into either the channel input or the Key input, offering a quick means of syn-chronizing other equipment to the input.

Ionchorpraíonn an 866 Series II tréithe “glúin bhog” ina ghníomh comhbhrúite chun fuaim nádúrtha a thabhairt faoi choinníollacha laghdaithe gnóthachain.

Seo a leanas na rialuithe agus a bhfeidhmeanna:

• Tairseach an Gheata: The Gate Threshold controls the level at which the 866 will allow the input signal through to the compressor section of the unit. If the signal level is below the threshold, no signal is allowed to pass. The red LED  will light whenever the signal is being gated. To disable the gating action, set the Gate Threshold control to the full counter-clockwise position (the gate control is fully independent of all other controls on the 866).
• Ionchur Gain: The Input Gain control allows you to adjust the signal level to the compressor. This control directly affects the setting of the Gate Threshold control and the Compressor Threshold control, and is active even when the Compress switch is in the out position. With the Input Gain control set to 0 dB, over 20 dB of headroom is available to the compressor.
• Compressor Threshold: This control sets the level at which the compressor begins to act. The Input Gain control affects the Compressor Threshold set-ting by changing the overall level that the compressor sees. When used in combination with the Input Gain control, the Compressor Threshold control can be adjusted to accommodate a wide range of signal levels.
• Cóimheas: Determines the amount, or ratio, of compression applied to the incom-ing signal. A ratio of 1:1 means that no compression is applied; a ratio of less than 10:1 is generally considered compression; a ratio of more than 10:1 is generally considered limiting; a ratio of ∞:1 allows no signal above the Compressor Threshold level setting.
• Ionsaí: This control adjusts the speed with which the compressor reacts to an increase in input signal level above the threshold. Shorter attack time set-tings will cause the compressor to react more quickly to transients, giving an added measure of protection to sensitive equipment. Longer attack times allow more of the transient to pass, yielding a more natural sound while still compressing the dynamic range of the signal.
• Scaoileadh: The Release control adjusts the speed with which the compressor reacts to a decrease in input signal level above the threshold. Faster release time settings can cause a sudden increase in noise on peaks for some pro-gram material as the compressor lets go. This effects is known as “breath-ing”. Increasing the Release time setting will help minimize breathing.
• Aschur Gain: Determines the output level of the compressor. This is useful when making up for gain lost in the compression process. The output level is active only when the Compress switch is depressed.
  Laghdú Gnóthachain: Léiríonn an graf barra sé-deighleogach LED seo an méid laghdaithe gnóthachain ag an gcomhbhrúiteoir. Oibríonn sé fiú nuair a bhíonn an lasc Comhbhrúite sa suíomh amach ionas gur féidir leis an úsáideoir réamh-mheasúnú a dhéanamh.view gníomh an 866 sula gcuirtear isteach sa chonair chomhartha é.
• Compress: The compress switch activates the compressor when depressed.
• Nasc Steirió: Depressing the Stereo Link switch links the two compressor channels for stereo operation. In stereo mode, the compressor will react to either channel, while reducing gain in both channels. Both channels of the 866 are identical in control and function EXCEPT when placed in the stereo mode. In stereo mode, the channel 1 controls become the master controls for both channels, while the Input Gain controls remain independent for each channel.

Seo a leanas ionchuir agus aschuir an phainéil chúl agus a bhfeidhmeanna:

• Ionchur: The inputs of the 866 will accept line level signals, either balanced or unbalanced. A 1/4″ tip-ring-sleeve phone jack and an RCA phono jack are pro-vided for each input. Using the 1/4″ input jack disconnects the RCA input jack.
• Aschur: The outputs of the 866 will drive either balanced or unbalanced lines. A 1/4″ tip-ring-sleeve phone jack and an RCA phono jack are provided for each output. Both the 1/4″ phone jacks and the RCA jacks may be used at the same time.
• Ionchur Slabhra Taobh: Allows access to the signal detector circuit of the com-pressor, permitting control of the compressor with another signal for such applications as “ducking”. When used with the Side Chain Output, the original input signal can be modified for applications such as “deessing”. Inserting a plug into this jack opens the internal side chain path so that the detector will only respond to the signal at this jack. In the stereo mode, both channels of the compressor react as one.
• Side Chain Output: The Side Chain Output is the buffered output normally fed to the detector. It is used in conjunction with the Side Chain Input to modify the detector signal for special applications such as “ducking” and “deessing”. For these applications, the Side Chain Output signal is sent to a signal processor and returned through the Side Chain Input.

IARRATAIS
A bhuíochas le solúbthacht an 866, is féidir leis go leor tascanna próiseála comharthaí a dhéanamh chomh héasca agus chomh soiléir céanna. Seo roinnt coincheapa is gá a thuiscint sula n-úsáideann tú an 866.
Is iad comhbhrú agus teorannú simplí dhá cheann de na feidhmeanna is coitianta don 866. Déantar comhbhrú agus teorannú ar bhealach cosúil, le dhá dhifríocht thábhachtacha: is gnách go mbíonn leibhéal an Chomhbhrúiteora agus na socruithe cóimheasa le haghaidh comhbhrú i bhfad níos ísle ná mar atá le haghaidh teorannú.

The Compressor Threshold controls the point above which the compressor begins to reduce the gain. For compression, the Compressor Threshold is set low, so that even low level signal will activate the compression. For limiting, the Compressor Threshold is set high so that all of the dynamics of the signal are preserved, but extremely high levels are reduced to protect amplascthóirí, cainteoirí, nó chun sáithiú téipe a chosc. Sa fheidhmchlár seo, ní thugann an brathadóir aird ar athruithe ar leibhéal an chomhartha faoi bhun na tairsí.

The 866 features a “soft knee” compression curve for more natural sounding compression. This means that as the signal level approaches the threshold setting, the compressor starts to react. The ratio, or slope, of the gain reduction continues to increase gradually as the signal passes above the threshold until it reaches the final gain slope set by the Ratio control. This feature makes the compressor’s operation less obtursive by easing into full com-pression. As you increase the compression Ratio, the “knee” gets sharper, and the gain reduction increases more rapidly with increased signal. Protective limiting requires a high compression Ratio setting, so that full compression is reached quickly.
The time it takes for the detector to react to an increase in signal level is deter-mined by the Attack control setting. To preserve some of the transient punch of a signal, the Attack time should be set fairly high. This allows the user to compress the overall dynamic range of a signal while still preserving the natural, open feel of the sound. For limiting, the Attack time should be short, so that potentially damaging transients don’t get past the limiting protection of the compressor.

Release time is the opposite of attack time. The Release time setting deter-mines the amount of time the detector takes to react to a decrease in signal level and to release the action of the compression. Faster release times will help preserve the original dynamics of the signal, but may cause a problem in some program material. This effect is called “pumping” or “breathing” . As the compressor lets go of the signal, the level of the signal (and the noise floor) is allowed to rise. When the next transient hits, the signal level is pushed down again according to the Attack time setting. Breathing can be minimized using longer Release times, which smooth out the action of the compressor.
Once a signal has crossed the threshold, the compressor must be told how much to reduce the gain. The Ratio control determines the amount of gain reduction, expressed as a ratio, adjustable from 1:1 (no gain reduction) to ∞:1 (the signal is not allowed to rise above the Threshold level). Compression ratios express the ratio between the input signal level and the desired output level. A compression ratio of 2:1 means that for an increase of 2dB above the threshold input signal, the compressor output will rise only 1 dB. At a ratio of 5:1, an input increase of 5dB above the threshold will yield an output increase of 1 dB, and so forth. The setting of the Ratio control is dependent upon the  application in which the compressor is to be used.

Hiss and signal processor idling noise are common sound reinforcement problems. The more signal processors there are in line with the program material, the more noise is produced at the final output stage. For this rea- son DOD has incorporated a noise gate in the 866. A gate acts like a compressor in reverse. When a signal crosses the gate threshold, it is allowed to pass unaffected. When the signal level falls below the gate threshold level,  the signal gain is attenuated, effectively shutting it off. The Gate Threshold control of the 866 allows the user to adjust the threshold level of the noise gate. When the control is in the fully counter clockwise position, the noise gate is inactive and all signals will pass through.
The Output Gain control allows the user to make up for gain lost in the com-pression process and to set the output level of the compressor for compatibility with other equipment.

OIBRIÚCHÁN STEIREO

Cruthaíonn comhbhrú comhartha dhá chainéal (steiréó) le dhá chomhbhrúiteoir neamhspleácha fadhbanna: má dhéantar cainéal amháin a chomhbhrú níos mó ná an ceann eile, aistreoidh an íomhá steiréó go taobh amháin, rud a chruthaíonn míchothromaíocht sa réimse fuaime steiréó a bhraitear. Chun cosc ​​a chur ar aistriú, tá lasc Nasc Steirió curtha san áireamh ag an Roinn Iompair ar an 866. Ligeann an lasc seo don dá chainéal rianú i gcomhchuibheas foirfe agus na braiteoirí do gach cainéal ag feidhmiú go neamhspleách. Nuair a bhíonn an lasc Nasc brúite, ceanglaítear na braiteoirí le chéile agus imoibríonn an dá chainéal leis an gcomhartha is airde den dá chainéal. Cuireann sé seo deireadh le sárú cainéal, agus caomhnaítear an íomhá steiréó.

IARRATAIS SPEISIALTA
The uses for a compressor don’t end with compression and protective limit-ing. Applications such as “ducking”, “deessing”, and “de-thumping” can be achieved with equal ease, and their uses are many.
Soláthraíonn an 866 Ionchuir agus Aschuir Slabhra Taobh, a cheadaíonn rochtain dhíreach ar chiorcaid braiteora gach cainéil. Ós rud é go rialaíonn na braiteoirí an VCA comhbhrúite (toirttagr-rialaithe amp(Lifier), is féidir ábhar an chláir a rialú le comhartha nach mbaineann leis ar chor ar bith. Déantar é seo tríd an gcomhartha rialaithe a chur isteach san Ionchur Slabhra Taobh.
Is iar-leannán maith é dúbadhampden chineál seo feidhmchláir. Is éard atá i gceist le ducking ná laghdú gnóthachain comhartha nuair a bhíonn ceann eile i láthair. Úsáidtear an teicníc seo go forleathan i gcraoladh spóirt chun leibhéal chomhartha chúlra an tslua a laghdú nuair a bhíonn an craoltóir ag labhairt.amplified voice of the announcer is sent to a side chain input to compress the noise of the crowd. The voice and crowd signals are then mixed together. For this type of application, the com-pression ratio is kept fairly low with long attack and release times.

The Side Chain output is provided so that the controlling signal (not the pro-gram material) may be modified before reaching the detectors.
The most common use of this technique is for deessing. A d-esser reduces the high frequency sibilance in the “s”s and “t”s of speech to prevent tape saturation or high frequency driver damage. Connect the Side Chain Output to an equalizer whose output is connected to the Side Chain Input of the 866.
The areas where most of the “ess” energy is located are between 2.5 kHz and 10 kHz. If these areas are boosted on the equalizer, the gain of the program material will be reduced more by the compressor because of the excess gain  in that frequency range, thus reducing the sibilance of the program material. Attack and Release times should be set fairly short, and the compression ratio should be below 8:1.
