SR Series EQ’s
DOD graphic equalizers offer both 1/3rd and 2/3rds octave models in stereo and
1/3 octave models in mono to meet any need.
INSTALLATION
Install the equalizer in a rack with the provided rack screws. Route the AC
power cord to a convenient power outlet away from audio lines. The unit may
be turned on and off using the front panel power switch. Since the units draw a
relatively small amount of current during idle, they can be left on continuously.
DOD equalizers generate very little heat during operation and thus do not need
to be specially ventilated or cooled. The units should not, however, be subject-
ed to high temperatures for extended periods. Although the unit's chassis is
shielded against radio frequency and electromagnetic interference, extremely
high RF and EMI fields should be avoided.
The XLR inputs and outputs are for balanced connections. Only the 1/4" phone
plug inputs and outputs can be used for unbalanced connections. Use only one
input/output connector pair at a time. Using more than one input/output con-
nector pair at a time can unbalance balanced lines, cause phase cancellation,
short a conductor to ground, or cause damage to other equipment connected
to the equalizer.
FOR BALANCED 1/4 “ TRS PHONE PLUG CONNECTION - Wire the con-
nectors as follows:

tip : high
ring : low
sleeve : ground
FOR 1/4" MONO PHONE PLUG CONNECTION:

XLR CONNECTORS - XLR type connectors are wired as follows:

Connector Connection Connection
pin 1: ground ground
pin 2: high high or hot
pin 3: low ground
Once the graphic equalizer has been installed and adjusted for the required
equalization and level, an optional security panel can be installed to keep unau-
thorized persons from changing settings.
