GT8 x 8 Instruction Sheet
Introduction:
Well done for purchasing a hand-built, eight channel, eight bus Absolute line mixer. The Absolute line of
small mixers differs from our normal Class A discrete transistor products because we don't want these mixers
to add any artifacts to the sound of the GTM822. We want the sound to be as pure as possible... hence the
term Absolute.
Unpacking Instructions:
Carefully remove the unit from the custom foam packing. The power supply works from any ac voltage from
85 volts to 240 volts, 50 and 60Hz.
Operating Guide:
All channels and bus output connections are via TRS 1/4” jack sockets. There are also two unity gain 25 pin
D-Sub connectors, one for the bus outputs and the other a direct input to the eight mix busses. These
connectors are used when cascading two or more 8 x 8 Absolute line mixers together.
There are two inputs per channel marked “PRE INPUT” and “POST INPUT”. The PRE INPUT normally
wires to the GTM822's channel pre-fade insertion send jack and the PRE RETURN jack is in parallel with
the PRE INPUT jack and intended as a loop through to a patch bay so that the GTM822's insertion path is
retained. The POST INPUT is wired to the GTM822 channel output XLR.
The PRE/POST switch on the front panel selects either of the inputs although, obviously, they could be used
with any two sources and not necessarily the GTM822. The unit was designed to enhance the features of the
GTM822 but could also be used as a stand-alone device.
