Power Switch: Switches the power on and off. Always make audio connections with the power switch in the OFF
position.
Power Cord Receptacle: Connects AC power to the equalizer.
Output Connectors: Three types of output connectors are provided for output connections: male XLR type con-
nectors, 1/4" tip-ring-sleeve phone jack connectors and a barrier strip.
Input Connectors: Three types of input connectors are provided for input connections: female locking XLR type
connectors, 1/4" tip-ring-sleeve phone jack connectors, and a barrier strip. The maximum input level that the equal-
izer can accept is +22dBu (ref: 0.775Vrms).
Chassis Ground Lift Strap: By removing the jumper connecting the two screws on the barrier strip, the chassis
ground is separated from the circuit ground of the equalizer. This is sometimes necessary to prevent "ground loops"
in a sound system. When lifting the ground strap, you must make a connection from the circuit ground ( ) terminal
to some other ground point in your audio system in order for the equalizer to function properly.
