GTx Input Module

The input module is the main method by which input signals are brought into the console. The GTx input module brings several new features to the Century Series, including a 5-seg- ment LED signal meter array, Adjustable Hi Pass filter, Insert switch, four-band sweep EQ (with selectable peak/shelving on HF & LF EQ bands and selectable Q on HM & LM EQ bands), 8 discrete AUX sends, and L-C-R (Left-Center- Right) bus assignment section.

48V Phantom Power Switch

Applies 48 Volts DC to pins 2 & 3 of the microphone input XLR jack for microphones requiring phantom power.

LINE Switch

Switches between the balanced female XLR microphone Input connector and the balanced Line Input 1/4" TRS con- nector.

PAD Switch

Introduces a -15 dB attenuation to the mic input signal, useful when handling high-gain signals.

GAIN Control

Adjusts input gain for proper signal level. Maximum gain is 70 dB.

Adjustable High Pass Filter

Reduces all low frequency content at a -12db per octave rate adjustable from 20 to 400 Hz (-3db point). Yellow LED illu- minates when switch is down.

Polarity Reverse Switch

Inverts the polarity of both the microphone and line inputs. The red LED illuminates when switch is down.

INSERT Switch

Switches any signal processing patched into the Input module (via the rear panel Send/Return jacks) in and out of the signal path. Associated green LED is illuminated when switch is down.

There are two knobs for each of the four bands. The inner knob controls the boost or cut (15 dB); the outer knob con- trols the center frequency. Center frequencies are indicated around the outer knob.

PEAK/SHELVE HF Switch

Used for switching the high frequency EQ between the nor- mal shelving setting to a peak setting.
