Connecting the EQM131

EQM131 31 BAND GRAPHIC EQUALIZER

OWNER'S MANUAL

The EQM131 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:

1.Turn off all equipment before making connections.

2.Mount equalizer in a standard-width 19" rack. 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.

3.Make audio connections via XLR, 1⁄4" TRS, or RCA jacks (according to application needs). 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 equipment connected to the equalizer. More than one output may be used simultaneously as long as the combined parallel load is greater than 2kΩ.

4.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.

5.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 front panel power switch or a master equipment power switch. Since the EQM131 equalizer consumes a relatively small amount of power, the unit may be left on continuously.
