1 MIC INPUT
You can plug in any stereo or mono line-level instrument using balanced or
unbalanced plugs. You 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.
2 LINE INPUT
This control adjusts the input sensitivity of the
MIC1channel. A signal applied to this input can
be adjusted for an optimal operating level. The

fully.
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.

AMX-80 is equipped with one low-noise microphone
pre-amplifier with 15V phantom power and 50dB of
gain. You 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.
Never try to connect a line-level signal to the
XLR MIC input when the phantom power functions.
