Balanced I/O

Some recording consoles have balanced sends and returns for the main output bus. If your recording console has these connections, use a balanced TRS cable to connect the left main insert send to the left INPUT of the equalizer, and another balanced TRS cable to connect the equalizer’s left OUTPUT to the left insert return. Repeat these steps for the right main insert.

You can also simply connect the balanced main outputs of the mixer to the inputs of the PEQ-450, then connect the outputs of the equalizer to the inputs of your mixdown recorder, monitor system, etc.

Connecting to the inserts on an instrument amplifier:

The insert sends on a guitar or bass amp are usually labeled "effects send and return" or "insert send and return". This allows you to amplify your instrument before compressing it and sending it to the power amp.

Another method would be to insert the PEQ-450 between the preamp and the power amp, if you are using a two-piece system. You should never put the equalizer between the power amp and the speaker, the high-powered levels created by the power amp will damage the unit.
