iEQ User Manual 6
The iEQ Series Equalizers have balanced inputs and 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 EQs in a rack with the rack screws provided. It can be mounted above or below
anything that does not generate excessive 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, 1/4” TRS jacks or Euroblock connectors according to applica-
tion 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 dam-
age to other equipment connected to the equalizer. More than one output may be used simul-
taneously as long as the combined parallel load is greater than 600Ω.
• 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 equip-
ment power switch. Since the iEQ Series Equalizers consume a relatively small amount of power,
the units may be left on continuously.
