The 2-Series Equalizers have balanced inputs and impedance balanced outputs that
can be used with any balanced or unbalanced line-level device.
To connect the equalizer to your sound system refer to the following steps:
• Turn off all equipment before making connections.
• Mount equalizer in a standard-width rack.
Install the EQ in a rack with the rack screws provided. It can be mounted
above or below anything that does not generate excessive heat. Ambient tem-
peratures should not exceed 113° F (45°C) when equipment is in use. Although
the unit’s chassis is shielded against radio frequency and electromagnetic inter-
ference, extremely high fields of RF and EMI should be avoided.
• Make audio connections via XLR or 1/4" TRS jacks (according to applica-
tion needs).
Both 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 equipment connected to the
equalizer. More than one output may be used simultaneously as long as the
combined parallel load is greater than 2k
Ω
.
• Select the operating range with the BOOST/CUT RANGE SELECTION
switch.
Note: Be sure to reduce audio levels at the power 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 turned on and off from the rear panel power
switch or a master equipment power switch (231 only). Since the 2-Series
Equalizers consume a relatively small amount of power, the units may be left
on continuously.
