EQ BYPASS SWITCH and LED:
Engaging this switch removes the graphic equalizer section
from the signal path. The BYPASS switch does not, however, affect the INPUT GAIN or LOW CUT
filters. The EQ Bypass LED lights up when the switch is pressed
2.
INPUT GAIN CONTROL:
This control sets the signal level input to the equalizer. It varies the
signal level from -12dB to +12dB. Its effect can be viewed on the OUTPUT LEVEL BAR GRAPH
3.
LOW CUT SWITCH:
The LOW-CUT switch when pressed inserts an 18dB/octave 40Hz Bessel
low-cut filter into the signal path
4.
BOOST/CUT RANGE SELECTION SWITCH AND LEDS:
This switch selects the two
boost/cut ranges of the equalizer, either ±6dB or ±12dB
5.
CLIP LED:
This LED lights whenever any internal signal level reaches 3dB below clipping
6.
OUTPUT BAR GRAPH LEVEL:
These four LEDs indicate output level of the equalizer. The
red LED is 3dB below clipping and is marked as +18dBu. It monitors the level at the output of the
equalizer after all other processing
7.
FREQUENCY BAND SLIDER CONTROLS:
Each one of these slider potentiometers will
boost or cut at its respective frequency by ±6dB or ±12dB, depending upon the position of the
BOOST/CUT RANGE switch. When all the sliders are in the center detent position the frequency
response of the equalizer is flat. The frequency band centers are marked at 2/3rd octave intervals on
ISO standard spacing
