GT Stereo Input Module

The GT Stereo Input Module is essentially two GT Input Modules fit into one module space. This module is very use- ful for accepting remote feeds, effects inputs and other sig- nals that require stereo handling.

48V Phantom Power Switch

Turns on 48V Phantom Power for both L and R XLR inputs, required by certain microphones for proper operation.

LINE Switch

Selects between the Balanced XLR Microphone Input con- nector and the Balanced Line Input 1/4" TRS connector for both L and R channels.

XLR PAD Switch

Introduces a -20 dB drop to the mic input signal for both L and R XLR inputs.

L GAIN & R GAIN Controls

Adjusts input gain for proper signal level for both L and R inputs.

80Hz High Pass Switch

For both input channels, reduces all low frequency content at a 12db per octave rate referenced to 80Hz (-3db point).

Polarity Reverse Switch

For both input channels, inverts the polarity of both the microphone and line inputs. An internal jumper selects between Left channel only or both Left & Right channels.

Three-Band Equalizer Controls

The equalization controls in this module act upon both L and R stereo channels at once. The upper band is a fixed shelving EQ with one control knob. The middle and low frequency EQ bands are set up as sweep EQ’s: the lower knob controls the gain or cut as in the fixed EQ; while the upper knob controls the center frequency adjusted by the inner knob. These center frequencies are printed on the chassis around the upper knob.

EQ IN Switch

Inserts the EQ section into both L and R input channel sig- nals at once. An associated LED illuminates when the switch is down.

AUX Level 1•3 / 2•4

Adjusts audio level of a mix for use as a monitor or an effect send. The signal source for this mix may be selected pre or post fader by an associated switch. The left channel is sent to the odd Auxes, and the right channel is sent to the even Auxes.

POST/PRE Switch

Selects the Aux 1•3 and Aux 2•4 signal sources between post and pre fader positions.

STEREO Switch

AUX 5-8 Individual Level Controls normally send a summed (L+R) signal to the AUX outputs. When the STEREO switch is depressed, AUX 5 and 6 become a ‘right’ send and ‘left’ send respectively. This can be used for a stereo effects send.
