Stereo Control 1 Introduction 1.1 Warnings and tips Before installing the module read this manual carefully. The manufacturer declines all responsibility for any damage due to incorrect use and/or use which does not conform to the instructions of this manual. 1.2 General description The Stereo Control is a device which allows the interfacing, insulation, level adaptation and control 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 range between 30 Khz and 80 Khz. Carefully check this feature and if necessary contact technical assistance to verify its compatibility. 8 7 1 2 1 - Audio stereo input with double RCA connector 2 - Signal balance pushbuttons 3 - Signal balance LED 4 - Power supply LED 5 - Infrared detector 6 - USB Connector 7-3.5 mm connector for cable with IR transmitter 8-8-pole connector for sound system BUS 6 5 4 3 SIGNAL BALANCE LED (3) POWER SUPPLY LED (4) OFF No signal GREEN Stand/By GREEN Audio signal present YELLOW On GREEN (1) Best setting ORANGE (2) Signal too high (1) ORANGE flashing on the peaks only (2) Continuous ORANGE 4
2 Installation Stereo Control 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. Adhesive IR transmitter 5 6 7 8 2 m long BUS cable (supplied) Sound system BUS Terminals 5 and 6 Stereo control L4561N Stereo source IR detector 1.8 long cable with IR transmitter supplied RCA/RCA cable (supplied) Please note: do not increase the cable length with an IR transmitter. If you use the Hi-fi system headphone output, mind the level of the volume. 5
Stereo Control 2 Installation 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 maximum 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) of Hi-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. 6
3 Configuration Stereo Control Before programming the Stereo Control (it must not be connected to the BUS): S = 1 4 device address in the system M1 =1 4 (indicate the number of Hi-Fi system modules, e.g. Radio, CD, which the Stereo Control must manage) If the multi-channel matrix (F441M) is used, only one Hi-Fi system module can be managed, so configure M1=1. Connect the BUS cable and then the RCA-RCA cable and the IR jack. 7
Stereo Control 3 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 operating system. If the configuration procedure fails, reset the device, disconnect the BUS SCS and the USB cable, and repeat the configuration. 5 6 7 8 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 8
4 Appendix Stereo Control 4.1 Troubleshooting PROBLEM CAUSA SOLUTION the ON/OFF LED (status indicator) does not light up. The Hi-Fi system is not controlled via IR. Power supply unit in protection mode. No 27 Vdc on the BUS terminal of the power supply unit. Incorrect IR cable wiring. Audio signal missing. Check and eliminate the cause of the short-circuit. Replace 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). 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. 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 ADJ LED stays off when the Hi-Fi system is active. 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 potentiometer 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). 9
