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.
Four-Band Sweep Equalizer Controls
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.
SWITCHABLE Q on HI MID and LO
MID EQ
Q is switchable between .8 (switch up) and 1.8 (switch
down).
PEAK/SHELVE LF Switch
Used for switching the low frequency EQ between the nor-
mal shelving setting to a peak setting.
