GTP8 Instruction Sheet
Introduction:
Well done for purchasing a hand-built, all discrete class A circuitry GTP8 eight channel microphone
pre-amplifier! It is designed to give you years of superb sounds and service.
Unpacking Instructions:
Carefully remove the unit and power supply from the custom foam packing. The power supply
automatically senses your local power voltage and can work between 85v and 265v. For best noise
performance always use a grounded 3 core / 3 pin a.c. cord.
If you connect the GTP8 to an unbalanced destination, wire to the XLR pins 2 and 3 only. Leave pin 1
high. This will help prevent ground loops.
The rear jack sockets are an unbalanced insertion at around -15dBu level.
Operating Guide:
The GTP8 can accommodate any signal you care to throw at it, including high-level line inputs. The
sensitivity switch provides gain adjustment in 10dB steps from +80dB to –10dB and the +/- 5dB level
pot allows for fine adjustments of level and also extends the gain range from +85dB down to -15dB.
The GTP8 does not have an output fader as it is anticipated to be used with the channel fader either in
the GTM822 console or the digital workstation the unit is connected to.
It is possible to fit an external fader to the GTP8 by using the rear panel channel insertion jacks. A
10Kohm audio taper fader could be connected as follows :-
Fader top = tip
Fader wiper = ring
Fader bottom = sleeve
The channel insertion jacks are intended to be used with our 8 channel 4 band Equalizer and is not
suitable for connecting to an external patch bay.
