EQ Type III Noise Reduction Switch: The switch
engages the EQ Type III Noise Reduction circuit
within the EQ.
EQ Type III Noise Reduction LED: The yellow LED
lights when the EQ Type III Noise Reduction circuit
is activated via the NOISE REDUCTION Switch.
Frequency Band Slider Controls: Each one of
these slider potentiometers will boost or cut at
its noted frequency by ±6dB or ±15dB, depend-
ing upon the position of the BOOST/CUT RANGE
switch. When all the sliders are in the center

4. CONNECTING THE EQ TO YOUR SYSTEM

The EQ-2231 Equalizers have balanced inputs and
outputs that can be used with any balanced or
unbalanced linelevel device. For more specific in-
formation about cabling possibilities, please refer
to the section entitled
To connect the equalizer to your sound system
refer to the following steps:
• Turn off all equipment before making con-
nections.
• Mount equalizer in a standard-width rack.
Install the EQ-2231 in a rack with the rack
screws provided. It can be mounted above or
below anything that does not generate ex-
cessive heat. Ambient temperatures should
not exceed 113° F (45°C) when equipment is
in use. Although the unit's chassis is shielded
against radio frequency and electromagnetic
interference, extremely high fields of RF and
EMI should be avoided.
• Make audio connections via XLR, barrier
strip, or 114" TRS jacks (according to appli-

detented position the output of the equalizer is
flat. The frequency band centers of the 2231 are
marked at 1/3rd of an octave intervals on ISO
standard spacings.
Low Cut Enable Switch: The LOW-CUT switch
inserts or removes the 18dB/octave 40Hz Bessel
low-cut filter from the signal path. When the
LOW-CUT switch is pushed in, the LOW-CUT filter
is IN the audio path.
cation needs) All three types of connectors
for the inputs and outputs can be used for
balanced or unbalanced connections. The
use of more than one connector at a time for
the inputs could unbalance balanced lines,
cause phase cancellation, short a conductor
to ground, or cause damage to other equip-
ment connected to the equalizer. More than
one output may be used simultaneously as
long as the combined parallel load is greater
than 60052.
• Select the operating range with the
BOOST/CUT RANGE SELECTION switch
Note: Be sure to reduce audio levels at the pow-
er amplifiers when changing the setting of this
switch as it may generate an audible transient.
• Apply power to the equalizer Connect the
AC power cord to the AC power receptacle
on the back of the equalizer. Route the AC
power cord to a convenient power outlet
away from audio lines. The unit may be
