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.

If you are using a two-piece system, another method would be to
insert the DEQ830 between the preamp and the power amp. 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
and outputs
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 DEQ830—they're
unnecessary and generally
sound awful because they
don't have the headroom to
handle the DEQ830's output.
Get a hard-wired adapter or
cable from your professional
audio dealer, or make one
yourself from components.

If you are connecting the DEQ830 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.
Connecting to equipment with ADAT Optical
inputs and outputs
inputs and outputs
The DEQ830 has the capability of receiving and transmitting its
audio signal in the digital domain. This is done through a pair of
ADAT Optical jacks found on the rear panel. The jacks are labeled
ADAT Optical In/Out. Each carries eight channels of audio, so all
eight of the DEQ830’s channels are handled by a single cable in
each direction.
Using the ADAT Optical jacks to connect to an external device
such as the Alesis ADAT HD24 is very easy, because the DEQ830
will automatically switch over to the ADAT Optical inputs when it
senses that a valid digital signal is present.
There are three ways to connect the DEQ830 with another digital
audio device, as explained on the next page.
