MONITOR SECTION
The PA 324 has two internal power amplifiers and
depending on the MODE selection switch, the ampli-
fiers are fed from the MAIN or MONITOR bus signal.
The following section describes the MONITOR bus
operation, which allows you to adjust the overall tone
and volume, and specify the mix level of the built-in
effects.
Graphic Equalizer
The PA324’s 7-band Graphic Equalizer allows
you to contour the frequency response of the
MONITOR bus signal, providing a maximum of
+/-12dB of cut/boost for each frequency band.
This is an especially useful tool for cutting fre-
quencies that cause annoying feedback. The
frequency response is flat when the sliders are
in the center position. Moving a slider in the
positive direction will boost that frequency by as
much as 12dB, and moving the slider in the
negative direction will cut that frequency by up
to 12dB. Once you set a frequency response
curve using the Graphic Equalizer, the EQ curve
is applied to both the MONITOR bus signal that
is sent to the monitor speakers, and the line
level signal which is sent from the MONITOR
OUT jack.
Effects Return Control (EFX RETURN)
The EFX RETURN control is used to adjust the level of the effect sound being sent back from the built-in
digital effect to the MONITOR bus. This allows you to hear the DSP effects in your monitor speakers.
Volume Control (MASTER)
The VOLUME level control is the overall master control for the MONITOR bus. The MONITOR level affects
both the MONITOR bus signal which is sent to the monitor speakers and the line level signal which is sent
from the MONITOR OUT jack.
Output Level Meter
The OUTPUT LEVEL METER allows you to monitor the level of the signal which is being sent to the MONI-
TOR OUT jack and MONITOR POWER AMPLIFIER.
NOTE: To avoid distortion, adjust the VOLUME level control so that the 0 indicator LED lights occasionally.
