The 20 Series Equalizers have balanced inputs and outputs that can be used with any balanced or unbalanced line-
level device. For more specific information about cabling possibilities, please refer to the section entitled
Installation Considerations, Page 5.
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, barrier strip, or 1/4" TRS jacks (according to application 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 cancel-
lation, 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 600 .
• 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. Since the 20 Series Equalizers consume a relatively small
amount of power, the units may be left on continuously.
