GL2800 User Guide
Using the Stereo Channels
channels and the two dual stereo returns present a unique flexibility.
The channels each include a patchable mic input and a stereo line
input. The returns each include two stereo inputs which can be mixed
together or used separately.
The mic preamp has a TRS jack MIC OUT breakpoint so that its output
can be used independently.
signal path feeding the channel and routes it to the jack instead. ST1
and ST3 stereo inputs can be routed either into the return channels or
directly to the LR mix.
switches which protect from accidental operation during a show.
The GL2800 provides 6 stereo inputs in a compact format.
Together with the 2 mics the stereos provide for a host of space
saving applications:
Standard Mono Microphone Channels Mono mic input through the
ST1 IN
stereo channel with 4band EQ, auxes and full routing.
True Stereo Microphone Channel
leads to patch both MIC OUT breakpoints into the stereo line input of
one channel. Set the stereo line level control on this channel to its
'0dB' position. Adjust the gain and balance between the left and right
microphones using the two mic GAIN controls. The other channel can
be used as a stereo effects return, sound effects or other line source.
Mixing Two Microphones through One Channel
OUT into the other channel stereo L/M input. On that channel turn up
the mic gain control to add its own mic, and the stereo line level
control to add the patched mic.
Patchable Microphone Preamplifier
breakpoint to disconnect the mic preamp from the channel and patch
it elsewhere to be used independently. For example, plug in a room
microphone and patch MIC OUT to a matrix EXT IN to add ambience
to a recording or monitor feed, or use it as a preamplifier for a
reference microphone with an RTA or other analysis equipment. You
could even use it to provide a better mic source to a video camera or
other recorder.
Dual Stereo Line Inputs
the ability to combine more than one source into a stereo channel,
each with its own level control. This can save channel space when
working with two similar sources routed to the same destination, for
example, two stereo reverb returns, two backing track or sound effects
players, or to alternate between walk-in music and recorded
announcement players. The two stereo return channels provide this
facility.
Using the Mute Groups
simultaneously mute combinations of input channels with a single key
press. For example, use a group to mute all the drum channels, or all
stage mics in a musical production. You could also assign a group to
mute all channels during the intermission. You could even use the
groups to recall the correct channel settings for different bands or
scenes during a theatre show.

never try to combine two outputs to one destination.
