REMOTE VOLUME CONTROL
The MASTER and BGM remote volume controls are independent. Insert a potentiometer between
the respective contact and the ground.
The potentiometer nominal value affects the operating
range (referring to the front panel settings): the
higher the value, the wider the adjustable range.
Its value can be typically from 10 kΩ to 100 kΩ, the
optimal action is obtained with an inverse logarithmic
curve potentiometer, but it is also acceptable a linear
response one.
The music remote control is relative to the activated music source (either internal or external).
The maximum range that can be obtained is 40 dB (relative to the signal adjusted by the main
settings).
IMPORTANT: If a remote control potentiometer is not foreseen, it is necessary to short-circuit the
respective contact to ground (through a wire), otherwise the MASTER volume and / or the BGM
volume are set to zero (muted).
MUSIC SOURCE REMOTE SELECTION
It is obtained by connecting a push-button between the SEL e GND contacts.
The selection is cyclic: CD/USB – MP3 player and tuner, AUX INPUT
