Connecting To The Inserts On An Instrument Amplifier - Alesis DEQ224 Reference Manual

Connecting to the inserts on an instrument
amplifier:
Unbalanced I/O
The insert sends on a guitar or bass amp are usually labeled
"effects send and return" or "insert send and return." This allows
your instrument to be boosted to line level before the signal is sent
to the equalizer, processed, and returned to the power amp.
Another method would be to insert the DEQ224 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, as the high-powered levels created by the power amp
will damage the unit.
Connecting to equipment with XLR inputs and
outputs:
If you are connecting the DEQ224 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.
Connections
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 DEQ224—they're
unnecessary and generally
sound awful because they
don't have the headroom to
handle the DEQ224's output.
Get a hard-wired adapter or
cable from your professional
audio dealer, or make one
yourself from components.
