GTQC Instruction Sheet

Introduction:

Well done for purchasing a hand-built, all discrete class A circuitry GTQC channel strip!

It is designed to give you years of superb sounds and service.

Unpacking Instructions:

Carefully remove the unit from the custom foam packing and fit the fuse into the fuse-holder. For best

noise performance always use a grounded 3 core / 3 pin a.c. cord. If you connect the GTQC to an

unbalanced source or destination, either use the ¼” jacks or wire to the XLR pins 2 and 3 only. Leave pin

1 high. This will help prevent ground loops.

The rear jack socket behind the pre-amplifier is mono and should be connected with a mono jack. If a

balanced TRS jack is plugged in, there will be a 6dB loss as there would be no signal on the ring contact.

The rear jack socket behind the compressor is also a mono jack. This is the side chain linking connector to

enable the GTQC to link to other GTQC compressors and link their side chains together for multi-channel

compression.

Wiring of this connector is tip = dc control volts, and sleeve = 0v (ground) common.

Operating Guide:

1. Preamplifier and Equalizer

The GTQC can accommodate any signal you care to throw at it, including high-level line inputs. The

sensitivity switch provides gain adjustment from +80dB to –10dB and the level pot allows for fine

adjustments. The level pot has an audio taper and is –20dB at half rotation. I would recommend using the

level pot between ¾ and full rotation and never below ½ rotation unless part of a deliberate fade. If you

have to turn the pot below ½ way, the sensitivity switch can be adjusted at least 4 clicks less! Operating

the unit in this fashion ensures that you keep the headroom in the designed 26dB region.

The D.I. input has 10 Megohm input impedance and around 10dB gain. It can be used (to great effect)

with musical instrument pickups, but works equally well with high-level signals like a D.A.T. or CD

player. The same gain structure rules apply.
