for connec ng to the inputs of an external eff ect devices or stage monitor amplifi ers.
47. AUX SEND 2 jack output
This jack connector sends out unbalanced line-level signals made of the sum of the input channel's AUX 2 sends, usually
for connec ng to the inputs of an external eff ect devices or stage monitor amplifi ers.
48. AUX SEND 3 jack output
This jack connector sends out unbalanced line-level signals made of the sum of the input channel's AUX 3 sends, usually
for connec ng to the inputs of an external eff ect devices or stage monitor amplifi ers. This signal can be pre or post fader,
it depends how POST switch (14) of each channel is set, usually all bu ons are set as pre or post.
49. AUX SEND 4 jack output
This jack connector sends out unbalanced line-level signals made of the sum of the input channel's AUX 4 sends, usually
for connec ng to the inputs of an external eff ect devices. This signal is post-fader, or in other words it depends on the
posi on of the channel's FADER.
50. AUX RETURN jack input
Unbalanced jack connectors of the auxiliary stereo input (note: the L input can be used as MONO if R input is le
unconnected). This input can be used for the return signal from outboard eff ects or for connec ng any instrument or

MAIN MIX bus.
55. GRP TO MIX switch
This switch assigns the GROUP 1-2 bus to the MAIN MIX bus. As explained earlier, pushing down this switch you can use
the GROUP 1-2 as sub-mix groups, enabling you to control the level of several channels with one knob.
56. MAIN MIX FADER level control
The MAIN MIX FADER controls the output level just before the MAIN MIX outputs. When the fader is fully down the
MAIN MIX is off , the "0" marking indicates a +4 dBu nominal output level. Typically this fader is set near the "0" label
and le alone, but it can be used for song fadeouts or quick system-wide mutes.
NOTE: the MAIN OUT is a true balanced output that can send the signal on a balanced line with or without a phantom
power ac ve. So the M1622USB mixer can also be used as a combina on mixer + DI box for sending the signals to a
