CHANNEL INPUT

1 MIC INPUT

AMX-80 is equipped with one low-noise microphone

pre-amplifier with 15V phantom power and 50dB of

gain. Y ou can connect almost any type of microphone.

Use phantom power only with condenser microphones

but please make sure the power switch is turned

off before connecting a microphone to the XLR input.

Phantom power will not damage your dynamic

microphones but it may damage tube or ribbon

microphones so make sure to read the microphone

instructions manual before using.

NOTE:

Never try to connect a line-level signal to the

XLR MIC input when the phantom power functions.

2 LINE INPUT

Y ou can plug in any stereo or mono line-level instrument using balanced or

unbalanced plugs. Y ou can also connect sound processors, CD Players, Tape

Players and MP3-iPOD Players to these sockets. When connecting a MONO

device, just remember to use The LEFT socket. The mono signal will anyway

appear on both left and right outputs.

3 TRIM CONTROL

This control adjusts the input sensitivity of the

MIC1channel. A signal applied to this input can

be adjusted for an optimal operating level. The

TRIM control provides 50dB of gain when raised

fully.

4 PEAK LED

Thanks to these little LEDs you know that the

signals applied to the mixer are adjusted properly

and that they come into the mixer without

distortion. Perform a sound-check with a microphone

or a line-level instrument such as keyboard and

adjust the TRIM control so that the LED blinks

occasionally ( In case of the line-level channels, you

must adjust the output level of the instrument

so that the LED blinks occasionally ).

A CLOSER LOOK: Unlike other competitors AMX-80 features Peak LEDs both

on the MIC channel and on the LINE channels. Most compact mixer of this kind

in fact do not present Peak LEDs for the Line channels and it is therefore very

difficult to prevent distorted signals coming into the mixer .
