Aurora Audio GT8x8 Absolute User Manual
Page 2
The red channel input level potentiometer has 10dB gain at fully clockwise to accommodate low input levels.
There are 8 bus assign button arranged to two columns with odd numbered busses on the left and even
numbered busses on the right. A pan-pot is selectable by pressing the “STEREO” button which enables the
signal to be panned between the left and right column busses.
At the top of the unit are the eight, blue, output bus level potentiometers. These are unity gain (0dB) when at
fully clockwise.
The GT8 x 8 Absolute has a wide number of uses and applications. It was designed originally to provide the
GTM822 with eight more mix busses for effects sends, etc. As it has the option for pre-fade inputs and stereo
panning, it could also be used as an eight input, four stereo output, cue headphone mixer.
The GT8 x 8 Absolute can be expanded to 16, 24 or 32 channels by means of cascading the 25 pin D-Sub
connectors and the inputs could also be linked to provide 16, 24 or 32 busses. It is a very flexible mix system!
