PEQ-450 Reference Manual

If you are connecting the PEQ-450 to a product with XLR balanced
inputs and outputs, you will need to convert this signal to a TRS
balanced connector. Make sure that Pin 2 of the XLR connector is
connected to the Tip  of the TRS adapter, and Pin 3 is connected to
the Sleeve.

Don't use line transformers: Many XLR-to-1/4" adapters sold at

electronics stores are NOT adapters, but transformers (and very

low quality transformers at that).  Don't use these on the output

of the PEQ-450—they're unnecessary and generally sound

awful because they don't have the headroom to handle the

PEQ-450's output.  Get a hard-wired adapter or cable from

your professional audio dealer, or make one yourself from

components.

Remember that the PEQ-450 is a dual-channel stereo equalizer. That
means that channels A and B can be used as two independent stereo
equalizers. It also means that audio from one channel does not affect
the other. Remember to plug audio into the Left or Right input of the
channel you are using.
