Heritage Audio is dedicated to bringing you ´the sound of yesterday for tomorrow ´. We specialize in capturing that unique, enticing sound that everybody has fallen in love with. For years engineers, producers and musicians have been yearning for that classic vibe. Usually the only option is to search for old, used original equipment that is almost always in a questionable state of operation. This brings with it a whole lot of other issues, making the experience less than desirable. Not to mention the very high prices asked for this equipment, which makes them virtually unobtainable for the great majority. Now it´s possible to obtain that same sound with a brand new piece that will give you all the problem-free, heavy-duty use you´ll need for years of music making history.

Using our Class A 73 Preamp building experience we were able to fit 8 MIC/Line preamps into a sturdy 2 unit rack. All 8 are faithful to our 3 stage all Class A design with Carnhill transformers fitted at the input and the output. The first two channels also include our high quality JFET DI as well as a fully sweepable Lo-cut filter. All 8 channels include switches for 48 V, Line, Lo-cut(-3 dB at 82 Hz) and Phase. There is built in analog to digital conversion available on 3 different digital formats: ADAT, AES/EBU and SPDIF with BNC connectors for reliable word clock syncing. Selectable sampling frequencies from 44.1 kH to 192 kH. Not only can the MIC/Line Preamp outputs be directly sent to the DAC, but there also exists the possibility of choosing an alternative input, per channel, for the digital conversion, making this an extremely flexible unit. This can really come in handy if you need to output the preamps to an EQ or compressor before returning them for digital conversion. 3 GETTING STARTED FRONT 7 1 5 2 3 4 9 6 8 10 11 12 13 14 1 INPUT GAIN SWITCH 5 dB Steps From 30 to 80 6 PHASE PUSH BUTTON Flips phase 180º 2 3 4 5 MIC INPUT IMPEDANCE (Lo z) 1200 or 300 when pressed MIC PAD PUSH BUTTON - 20 dB Pad, Ahead of the Input Transformer OUTPUT ATTENUATOR Attenuates from 0 to Infinity HIGH PASS FILTER -3 dB at 82 Hz, Discrete Class A 7 8 9 10 LINE PUSH BUTTON Switches from MIC/D.I. to Line HIGH PASS FREQUENCY SELECTOR Continually Adjustable CutOff for HPF PHANTOM POWER SWITCH Turns Phanton Power On D.I.

This same protocol is also used by AVID amongst many others, and is a follows: Pin-out for TASCAM DB25 8 Channel Balanced Connector H = HOT C = COLD G = GROUND The list of the DB25 connectors used and their corresponding channels are as follows: CHANNEL INPUTS 1-8: TASCAM DSUB CHANNEL I/P CHANNEL # 1-8 1 INPUT # 1 2 INPUT # 2 3 INPUT # 3 4 INPUT # 4 5 INPUT # 5 6 INPUT # 6 7 INPUT # 7 8 INPUT # 8 CHANNEL OUTPUTS 1-8: TASCAM DSUB CHANNEL O/P CHANNEL # 1-8 1 OUTPUT # 1 2 OUTPUT # 2 3 OUTPUT # 3 4 OUTPUT # 4 5 OUTPUT # 5 6 OUTPUT # 6 7 OUTPUT # 7 8 OUTPUT # 8 ADC RETURNS 1-8: TASCAM DSUB CHANNEL # ADC RETURNS 1-8 1 ADC RETURNS # 1 2 ADC RETURNS # 2 3 ADC RETURNS # 3 4 ADC RETURNS # 4 5 ADC RETURNS # 5 6 ADC RETURNS # 6 7 ADC RETURNS # 7 8 ADC RETURNS # 8 It is worth noting that, in order to avoid ground loops, the DB25 ground connections are lifted on the Súper 8 side, leaving the ground paths of your DB25 snakes only acting as shields and preventing any current returns. 10 SPECIFICATIONS ANALOG I/O · Microphone input impedance only channels 1 & 2: High=1200 minimum; Low= 300 minimum.

Condenser microphones don´t seem to work with Súper 8. Make sure the red +48 V button is pressed in to activate the phantom power sent to the microphone. There doesn´t seem to be any output at all from the unit. Check to see if the OUTPUT knob is fully turned down as this will attenuate the signal completely. Sending a signal to the unit from a DAW overloads it terrible. It is necessary to press the LINE button when sending it a line level source. If not, it is expecting a Microphone signal with a very different impedance. There is no signal arriving from the ADC. Make sure the corresponding button in the ADC Routing is pressed if the Preamps direct out is desired. There is still no signal arriving from the ADC. Double check that the appropriate connector is indeed inserted properly. There are clicks being generated. Make sure you have selected the correct Sampling Frequency. There are clicks being generated. Make sure you are using a BNC cable to connect the Word Clock if being slaved. There are unexpected noises and/or jitter being produced.
