For suspended installation, only use the dedicated anchoring points and do not try to hang this product by using elements that are unsuitable or not specific for this purpose. Also check the suitability of the support surface to which the product is anchored (wall, ceiling, structure, etc.), and the components used for attachment (screw anchors, screws, brackets not supplied by RCF etc.), which must guarantee the security of the system / installation over time, also considering, for example, the mechanical vibrations normally generated by transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless this possibility is specified in the user manual. - RCF S.p.A. strongly recommends this product is only installed by professional qualified installers (or specialised firms) who can ensure correct installation and certify it according to the regulations in force.
The entire audio system must comply with the current standards and regulations regarding electrical systems. - Supports and trolleys.
The equipment should be only used on trolleys or supports, where necessary, that are recommended by the manufacturer. The equipment / support / trolley assembly must be moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may cause the assembly to overturn.
IMPORTANT
- There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).
- Hearing loss.
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones. See the manual technical specifications to know the maximum sound pressure level.
IMPORTANT NOTES
To prevent the occurrence of noise on line signal cables, use screened cables only and avoid putting them close to:
– Equipment that produces high-intensity electromagnetic fields.
– Power cables.
– Loudspeaker lines.

REAR PANEL
- FEMALE XLR INPUTS (BAL/UNBAL). The system accept XLR input connectors.
- MALE XLR SIGNAL OUTPUT. The output XLR connector provides a loop through for speakers daisy chaining. The balanced connector is connected in parallel and can be used to send the audio signal to other amplified speakers, recorders or supplementary amplifiers.
- SYSTEM SET UP ENCODER. Push the encoder to select a function (gain reduction, delay, preset). Rotate the encoder to select a value or a preset.
- GAIN REDUCTION LED. Pushing the encoder once the gain reduction indicator lights green.
Then rotate the encoder to reduce the gain to the right level.
POWER LED. This green led is ON when the speaker is connected to the main power supply. - DELAY LED. Pushing the encoder twice the delay indicator lights green. Then rotate the encoder to delay the speaker. The delay is expressed in meters.
SIGNAL LED. The signal indicator lights green if there is audio signal present on the main - PRESET LED. Pushing the encoder three times the preset indicator lights green. Then rotate the encoder to load the right preset to the speaker.
LIMITER LED. The amplifier has a built in limiter circuit to prevent clipping of the amplifiers or overdriving the transducers. When the soft clipping circuit is active the LED blinks RED. It is okay if the limit LED blinks occasionally. If the LED lights continuously, turn down the signal level. - SYSTEM SET UP DISPLAY. Display the system setting values. In case of RDNet active connection a rotating segment will light up.
- RDNET LOCAL SETUP/BYPASS. When released the local setup is loaded and RDNet can only monitor the speaker. When switched the RDNet setup is loaded and bypass any speaker local preset.
- RDNET IN/OUT PLUG SECTION. The RDNET IN/OUT PLUG SECTION features etherCON connectors for the RCF RDNet protocol. This allows the user to completely control the speaker using the RDNet software.
- AC INPUT. Powercon locking 3-pole AC mains.
- AC OUTPUT. Powercon locking 3-pole AC mains output.
- POWER MAIN SWITCH. The power switch turns the AC power ON and OFF.
WARNING: the Powercon connector is used to disconnect the system from the power supply network. It shall be easily accessible after the instillation and during the use of the system.
THE REAR ENCODER CONTROL AND SPEAKER SETTING
Pushing the rear encoder it is possible to select the following three functions:
– input gain reduction
– speaker delay setting
– selection of a speaker preset
INPUT GAIN REDUCTION
Pushing once the rear encoder the gain reduction LED will light up. Now rotating the encoder counter clockwise it will be possible to reduce the input gain. The gain reduction will be in steps of 0,1 dB for the first 10 dB and than in 1 dB steps.
The maximum reduction is 99 dB.
SPEAKER DELAY SETTING
Pushing a second time the rear encoder the delay LED will light up. Now rotating the encoder clockwise it will be possible to delay the signal output of the speaker.
The delay is expressed in meter. The delay will be in steps of 0,1 m for the first 10 m and than in 1 m steps. The maximum delay will be 20 meter.
SELECTION OF A SPEAKER PRESET
Pushing a third time the rear encoder the preset LED will light up. Now rotating the encoder clockwise it will be possible to select a preset.
There are eight presets in three groups:
– CLOSE (C). When the listening distance is less than 4 meter
– LINEAR (L). When the listening distance is from 4 to 11 meter
– FAR (F). When the listening distance is more than 11 meter.
L1. LINEAR. Is the totally linear preset. The speaker curve response is perfectly linear. It is ideal when listening outdoor or in low reverberation rooms, at medium distance and at a medium or high sound pressure level.
L2. LINEAR HIGH PASS. This preset is the same as L1 with a 24 dB/oct. high pass filter at 100 Hz. To be used when the speaker is a part of a bigger system, when is a satellite of a subwoofer system or when the application is speech reproduction.
L3. LINEAR LOW LEVEL – PLAYBACK. This preset is linear with a gentle +3 dB boost at low frequency. To be used when playing at low level or for playback music.
L4. LINEAR INDOOR. This preset is linear with a gentle -3 dB shelf at low frequency. It is ideal for a better sound balance in reverberant rooms and for indoor speech reproduction. C1. CLOSE. Close listening preset. To be used when the average listener is closer than 3 meter. The preset shows a gentle -3 dB shelf in high frequencies. The sound balance is natural and never aggressive.
C2. CLOSE HIGH PASS. This preset is the same as C1 with a 24 dB/oct. high pass filter at 100 Hz.
F1. FAR. Far listening preset. To be used when the average listener distance is more than 10 meter. The preset shows a +3 dB shelf in high frequencies to compensate the air absorption.
The clarity and intelligibility in distance are improved.
F2. FAR HIGH PASS. This is the same as F1 with a 24 dB/oct. high pass filter at 100 Hz.
After the parameter settings the 2 digits display will flash one time. This represent saving all the preset values in the speaker memory.
Once saved, all the speaker settings are permanent. It is possible to turn off and turn on, the speaker will remember the last settings.
To reset the speaker to the original settings :
– turn off the speaker
– keep the encoder pressed
– turn on the speaker
– the status yellow led will be blinking slowly, keep the encoder pressed
– the status yellow led will be blinking fast, now release the encoder
– the reset procedure is finished
SAVING A SPEAKER PRESET
Using the RDNet IN/OUT connection it is possible to load in the speaker memory a dedicated user equalisation. The speaker reset procedure will cancel even this equalisation.
SPEAKER RESET
The XLR connectors use the following AES standard:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
CONNECTIONS
BEFORE TURNING ON THE SPEAKER
At this point you can connect the power supply cable and the signal cable, but before turning on the speaker make sure that the volume control is at the minimum level (even on the mixer output). It is important that the mixer is already ON before turning on the speaker. This will avoid damage to the speakers and noisy “bumps” due to turning on parts on the audio chain. It is a good practice to always turn on speakers at last and turn them off immediately after the show.
Now you can turn ON the speaker and adjust the volume control to a proper level.
INSTALLATION
WARNING: daisy chaining speakers always make sure that the maximum current requirement does not exceed the maximum admitted POWERCON current. In case of doubt call the closest RCF SERVICE CENTRE.
WARNING: The powercon connector is used to disconnect the system from the power supply network. It shall be easily accessible after the installation and during the use of the system.
