ADVISES :
-To optimise the performances of your amplifier, you should switch it on at least
half an hour before any listening, the time for power stage to reach their ideal
working temperature. Between two uses, it is better to let it on stand-by position, so
that the power stages remains at their optimal temperatures.
-We advise you to use good wires to link with the other elements (CD player,
loudspeakers…). Don't hesitate to take advisesfrom your dealer.
MODE BRIDGE MONO
Careful : Switsh OFF your appliance before using this mode.
You can transform your AM400 power amplifier as a mono bridge amplifier.
Activate the Switsh (11) at the rear of the appliance on MONO. PRE-OUT Outputs
of the preamp must be connected to the Right Inputs of each Amplifier.
For each Amplifier, terminal + (red) of the Right Output (1) has to be connected to
the terminal + (red) of the speaker and terminal + (red) of the Left Output (2) to the
terminal – (black) of the speaker.
Wiring of the speakers will be the same while using RCA or XLR cables.
