The front panel of the AMP20 contains all the control and indicator functions.
Two gain control potentiometers are provided with which the gain of the line and
microphone inputs can be regulated separately and the balance between the music
and speech can be set.
A slide switch provides the possibility to switch the amplifier between Stereo and
Mono / Bridge mode. If this switch is set to stereo, the output will be stereo. If its set
to Mono / Bridge, the Left and Right channels will be summed to a dual-mono output.
Three indication LED’s for ‘ON / STANDBY’, ‘SIGNAL’ and ‘CLIP’ indicate the operation
mode of the amplifier. The ‘ON / STANDBY’ LED will turn green when the device is
switched ON and running. When no signal with a sufficiently high level is detected
for a certain period of time, it will switch to standby mode and this LED will turn
orange. The ‘SIGNAL’ LED will turn green when a signal with a sufficiently high level
is detected and the ‘CLIP’ LED will start blinking when the signal reached the clipping
level and the internal limiter starts working.
