Input Channels; Volume Controls; Output Section - Galaxy Audio JIB/MM Owner's Manual

Input Channels:

The Input Channel connectors are numbered 1 through 4 and
located on the left side of the unit. Inputs 1 and 2 are Balanced
Combination jacks that accept either XLR Mic or ¼" line cables.
Phantom Power is supplied to the XLR connectors on Inputs 1
and 2 when the Power Switch is in the ON+24v PHAN position.
If Phantom Power is not required the MM should be operated with
the Power Switch in the ON position. Channel 3 features both
Stereo RCA and Stereo 1/8" jacks for convenience, however we
do not recommend using both types simultaneously. Channel 4
features Stereo RCA jacks.

Volume Controls:

Volume Controls, which correspond to channels 1 through 4, are
located on the top panel of the MM. Channels 1 and 2 also feature
Pad switches, located next to the Volume Controls, which will
reduce the gain (of the XLR inputs only) by –20dB to accommodate
very strong input signals. The Pads are engaged when the switches
are in the down position. Optimum performance is obtained when
the Volume Controls can be set generally in the middle of their
range rather than at the extreme MIN or MAX.

Output Section:

Various Output jacks are located on the right side of the MM. The
mix created with the 4 Input Volume Controls will appear at all
Output jacks. Stereo signals from Inputs 3 and 4 are presented in
stereo at the RCA and 1/8" Headphone Outputs. The Headphone
Level controls only the volume of the Headphone Output jack. This
may also be used as a master volume control if the Headphone
Output jack is patched to a line input on another device. Stereo
signals from Inputs 3 and 4 are summed to mono at the XLR and
¼" Balanced Mono Outputs. The "Mic/Line switch located between
the XLR and 1/4" Balanced Mono Outputs allows for selecting either
a Mic Level Balanced Mono Output or a Line Level Balanced " " " "
Mono Output.
