Description
The device manages and interfaces an external stereo audio source
(e.g. Hi-Fi system) with infrared remote control and only one IR detector.
The device can save and reproduce the controls given by the stereo source remote control.
The controls saved by the stereo control are sent to the external stereo control through
a cord with infrared transmitter (supplied). In this way one can, by means of the various
control devices (special controls and Touch Screen, etc...) and the ampliers, manage the
switching on of the saved stations and activation of a CD reader and change the CD track.
On the front of the stereo control there are pushbuttons which, with the aid of an
indication LED, adjust the audio signal entering the device.
Stereo control must be programmed using the conguration software supplied with the
product. During normal operation of the stereo control, when the device activates the
Hi-Fi, the loudspeakers directly connected to the system also come on. When the last
amplier goes o, following an OFF control, the loudspeakers also go o, but the HI-FI
system remains active for one minute.
Note (*): The device might not be compatible with some remote control brands and
models

Conguration
S1: 1-4 local address of the source
M1: 1-4 Conguration of how many devices must be controlled inside the same
device, Max 4 (example HI-FI systems with radio, cd reader etc...).
M2: 1-6 time which elapses between a control and the next during the source
switching on sequence (see instruction sheet).
When using the multichannel matrix, item F441M, the conguration must
be M=1 (management of one source only).
