Stereo ControlInstallation manual

1.2 General description

The Stereo Control is a device which allows the interfacing, insulation, level adaptation and con-trol via infrared signals between an external stereo source and the sound system BUS.The item enables you to store and replicate INFRARED remote control codes with an operating rangebetween 30 Khz and 80 Khz. Carefully check this feature and if necessary contact technical assis-tance to verify its compatibility.

1.1 Warnings and tips

Before installing the module read this manual carefully.

2.1 Wiring diagram

Install the cable with IR transmitter, applying the adhesive part of the transmitter close (max 1 cm) to the source IR receiver (do not connect the transmitter above the IR receiver). The maximum distance between the device and the source must be 1 m.

WARNINGS

• Before programming the Stereo Control, make sure that the remote control batteries of your hi-Fi are sufficiently charged.

• Check the position of the hi-Fi system LED and place the cable with the IR transmitter at a maxi-mum distance of 1 cm from it.

• Make sure there is only one hi-Fi LED (it is not possible to manage several source-LEDs).

• When using the Stereo Control, do not use the remote control of the hi-fi system.

• The pickup capacity of the Stereo Control is between 30 Khz and 80 Khz; operation outside this range is not guaranteed.

Given the continuous technical and functional developments (infrared remote controls) ofhi-Fi systems, the manufacturer recommends to check the compatibility of the device. To do so, please contact the Call Centre or your nearest Technical Service Centre.

Stereo ControlInstallation manual

Before programming the Stereo Control (it must not be connected to the BUS):

3 Configuration

S = 1 – 4 device address in the systemM1 =1 – 4 (indicate the number of hi-Fi system modules, e.g. Radio, CD…, which the Stereo Control must manage)

Connect the BUS cable and then the RCA-RCA cable and the IR jack.

If the multi-channel matrix (F441M) is used, only one hi-Fi system module can be managed, so configure M1=1.

3.2 Reset

Restore the factory settings as follows:

• Switch the Stereo Control off

• Configure: S = – ; M1 = – ; M2 = 9

• Switch the device back on and wait for LED 3 to light up

• Switch off and restore the configuration

3.1 Programming

• To program item L4561N use the software supplied in the CD which comes with

• the device, referring to its manual.

• Do not use USB cables exceeding 5 metres as this will cause the device not to be recognised by the operat-ing system.

• If the configuration procedure fails, reset the device, disconnect the BUS SCS and the USB cable, and repeat the configuration.

4.1 Troubleshooting

PROBLEM CAUSA SOLUTION

the ON/OFF LED(status indicator) doesnot light up.

Power supply unit inprotection mode.

Check and eliminate the cause of the short-circuit.Replace the power supply unit.

No 27 Vdc on the BUS terminal of the power supply unit.

Make sure there is 24 – 27 Vdc at the OUTPUT of the A/V Node to which it is connected. If there is no voltage, eliminate the short-circuit on the BUS (at the OUT side of the A/V Node).

The Hi-Fi system isnot controlled via IR. Incorrect IR cable wiring.

Check and correct wiring. the cable with the IR transmitter must be placed at a distance of 1 cm from the IR receiver of the hi-Fi system to be managed.

The ADJ LED stays off when the Hi-Fi system is active.

Audio signal missing. Check if there is an audio signal.

Very low audio Signal.

Check the adjustment of the level potentiometer or increase the level of the signal given by the external source.

The level LED is always red. Adjust the level potentiometer correctly.

The signal is distorted, even at low volumes.

Make sure the level LED does not turn red when playing tracks. Adjust the potentiom-eter of the active hi-Fi system so that the LED is always green (it can only turn red for a very short time, during musical peaks).
