Aurora Audio GTM822-2GN - Manual (Page 3)

The VU meter measures the signal level at the pre-fade insertion return point. This
means that, with nothing plugged into the insertion, it will measure input level and
with a device plugged into the insertion, it will measure the output level of that
device. Thus, in the event of the device being a equalizer with boost or compressor
with gain make up, the level can be adjusted either by the stepped gain control
(device input) or the fader (device output) and this will provide the user with a
convenient way of adjusting the channel level for the best and/or desired sound.
The channel can be assigned to four busses: - Post fade signals to the stereo output
busses (via a pan pot, if required) and a pre fade signal to the Cue/Aux busses via
a separate level control.
The ouput bus assign path now has a pan switch which, if not selected, allows
identical level signals to be sent to either or both output busses. When the pan
switch is selected, the zero insertion loss panpot is selected and the channel signal
can be positioned anywhere between full left and full right pan.
The Cue/Aux bus sends are pre fade and not affected by the pan pot. In the event
that the busses are used as an effects send, there is a stereo effects return path to
busses left and right in the GTM monitor section complete with a stereo level
control and mute switch.
At the bottom of each channel are three switches; the yellow switch is solo-in-
place while the red switch is channel cut. Silent opto-isolator switching controls
all solo and muting functions. The blue button is the source selection switch
mentioned in section #2.
Pressing a channel solo button will mute all the other channels, lighting their red
mute switches to confirm this. Any channel can be released from muting by
pressing the associated solo switch and all solo switches need to be released for all
channels to function without muting.
There is a post fade channel output available at the male XLR on each channel as
well as simultaneously at the 25 pin “D” connector. As each channel has a
maximum gain of 20dB they can also be used as an interface with –10dBV
consumer equipment, bringing their signals up to pro-audio +4dBu levels.
