For immediate diagnosis you can check if there is the presence of audio signal thanks to the LEDs
on the card.
•Audio Led: If on, it indicates the presence of audio and the status of the amplifier.
•Status Led: Fast linking for 10 seconds after power on, indicates the startup status of the
module. Slow flashing indicates turning off, after 5 minutes, of the amplifier.
•Broken Fuse Led: If on, it indicates that the fuse is lown and must e replaced (2A).
Thanks to a potentiometer located on the rear of the electronics, it is possi le to adjust the threshold
audio level detecta le y the device.
In the case in which the module does not come into SLEEP MODE, for default after 5 Minutes, it
will e enough to lower the threshold y rotating the potentiometer.
In the opposite case, if the signal is too low and the amplifier will not turn on, simply increase the
threshold until it turn on.
The other potentiometer is used to increase the delay time in SLEEP MODE, from a minimum of 1
minute to a maximum of 20, default is set to 5 minute.
