IMG STAGE LINE MMX-1221, Instruction Manual

Stage Line

R

12

A professional audio mixing console with 100 mm HQ-faders and external special power supply. Built into a stable
flight case it is ideal especially for stage applications.  
Latest electronic technology ensures extremely low noise levels and great reliability.
Although it is neither complicated to install nor difficult to operate this device, a few minutes of your time are
required to read this manual for becoming familiar with the various features and how to use them.
Please take great care when unpacking the console. Do not discard the carton and other packing materials. They
might be needed for transport if it ever becomes necessary to return the device for service.
Never place the unit near radiators or in front of heating vents. Do not expose it to direct sunlight, excessive
humidity or dust to avoid early damage.

Features:

12 / 16 / 20 Input Channels *...................

Electronically balanced, switchable MIC / LINE, with gain control, 
subsonic filter, phantom supply with central switch (MIC-inputs),
3-way equalizer, bass / mids semiparametric,
4 AUX  controls, arranged as 2xPRE- / 2xPOST fader  sends,
routing switches to the stereo-and / or mono-groups,
PFL switch (headphones monitoring and VU-display of the channel signal),
PANPOT for the stereo outputs L-R,
PEAK LED for signal monitoring,
pre-fader insert in every channel.

4 Stereo-AUX-Inputs   .............................

Unbalanced, with gain control, switchable to the stereo-sum,
useful as line-inputs or effect-returns, two inputs with slope control.

1 STEREO Output...................................

Unbalanced, with individual L-R faders and pre-fader insert jacks, 
low  impedance outputs with hum compensation.

1 MONO Output ......................................

Unbalanced, including hum cancelling circuit, pre-fader insert jack, 
low output impedance, composed of the stereo sum L-R or  of the 
individual channels 1-16.

4 AUX Outputs ........................................

Unbalanced, with level  controls, routing- and AFL-switches.

1 RECORD Output..................................

Parallel to the L/R output, but with reduced signal level (-10 dB).

1 Stereo-Headphones Output  ................

Provided for monitoring of the individual channels (PFL) or the 
output groups L-R, MONO, AUX1-4 (AFL).

Level Indication .......................................

2x16 step LED bargraphs for indication of the group signals L-R or 
MONO, automatic switching over to display the PFL / AFL signals 
on the right bargraph.
