Controls and Connectors
INPUT:
Signals to be processed are connected to the Audio
Monitor at these two BNC jacks (
Ch. 1
and
Ch. 2
).
CHANNEL:
This toggle switch determines which of the two
input signals will be processed.
GAIN:
This three position switch controls the level of signal
gain. The switch allows the user to select from
X1
,
X10
, or
X100
gain.
NOTCH FILTER:
In the ON position, this filter will attenuate
line noise (Either 50 or 60 Hz, depending on the country of
use).
GRAPHIC EQUALIZER:
These 6 slide potentiometers adjust
the gain of a narrow range of frequencies. Each slide
potentiometer can boost/increase (
+
) or attenuate/decrease
(
-
) the gain around the center frequency indicated (160Hz,
400Hz, 800Hz, 1.6kHz, 3.2kHz, and 8.0kHz) by 12dB.
LINE OUT:
This BNC connector provides the output signal
from the amplifier channel. The toggle switch determines if
this signal is
FIXED in gain relative to the input signal (at the
level determined by the
GAIN
toggle switch or includes the
VARIABLE amplification provided by the
GRAPHIC
EQUALIZER AND VOLUME
control.
VOLUME:
This potentiometer adjusts the output volume of
the speaker, and the variable amplification to the processed
signal.
Warning: It is recommended to turn this knob to
the off position before attaching an input signal to the
Audio Monitor, in order to prevent damage to the speaker,
and any nearby eardrums.
HEADPHONES JACK:
Insertion of a mini-headphones plug
into this jack will disable the internal speaker, and power the
user supplied headphones.
