Peavey GTX Power Supply User Manual


 
Matrix Module
The Matrix module allows the creation of an independent mix
using the Main outputs and an external inputs as signal
sources.
Matrix Meter
Shows output level of matrix module, 0dB=+4dBu.
Matrix AUX IN Controls
Controls level of external balanced input signals.
L & R MAINS Controls
Controls level of post fader L & R signals from main section.
MONO MAINS Control
Controls the level of post fader Mono signal from main sec-
tion.
STR PGM IN Control
Controls level of Stereo Program being input into the matrix
from the mono master module circuit.
LEFT/MONO/RIGHT Switches
Selects which stereo program in signals are introduced into the
matrix.
GROUPS 1-4 Controls
Adjusts the level of Group signals 1-4 introduced into the
matrix.
GROUPS 5-8 Controls
Adjusts the level of Group signals 5-8 introduced into the
matrix.
MUTE Switch with LED
Mutes the output. This switch does not affect the PFL switch
or the Peak and Signal Present LED indicators.
TB ENABLE Control
Injects the talkback signal from the Master section into the
matrix.
PFL Switch
Samples the matrix signal pre-fader and allows for monitoring
within the master section of the console. This signal
is not
affected by the Mute switch. When depressed, the signal level
can be seen on the Solo meters, and heard via the mixer’s
headphone or local monitor output. When this PFL switch is
depressed, the PEAK LED illuminates at a lower intensity.
When used as a status indicator of switch position, the Peak
LED indicating circuit remains fully operational by illuminat-
ing at a much higher intensity than its use as a PFL status indi-
cator.
PEAK LED Indicator
Illuminates RED when any of the points monitored come with-
in 3db of the clipping point. Signal is sampled after the sum-
ming stage and after the fader. This LED also serves as a PFL
ON indicator, but at a much lower intensity than when it is
used to indicate clipping.
SIGNAL PRESENT LED
Constantly displays level activity of the matrix by varying in
intensity.
MATRIX OUTPUT LEVEL
Used for control of the Matrix output of the channel.
