2 Connections

Mono connections

This example shows how to connect the DEQ230 to one mono

source. You can use this method to connect two mono sources or

one stereo source to the DEQ230. You would need two insert

cables to make both of these connections.

Stereo connections

Use two insert cables to connect the DEQ230 to the main L/R

bus in the same way you would connect it to a pair of channel

inserts. Simply connect one insert cable to the left main insert of

the mixer, and connect the two mono jacks to the CHAN A

INPUT and OUTPUT of the DEQ230. Use another insert cable

to connect the right main insert to the CHAN B INPUT and

OUTPUT of the DEQ230.

You can also simply connect the balanced main outputs of the

mixer to the inputs of the DEQ230, then connect the outputs of

the equalizer to the inputs of your mixdown recorder, monitor

system, etc.

Balanced I/O

Some recording consoles have separate balanced jacks for the

sends and returns instead of a single TRS jack. If your recording

console has these connections, use a balanced TRS cable to

connect the insert send to the INPUT of the equalizer, and

another balanced TRS cable to connect the equalizer OUTPUT to

the insert return.

Operating Levels

The DEQ230D can operate in either a +4dBu or –10dBV setting.

A rear panel switch allows you to configure the unit to your audio

environment.

The DEQ230 is a “line level” device, which means that it operates

at a nominal level of –10dBV, with a maximum input level of

+8dBV. Some equipment operates at a nominal level of +4dBu,

and can run the signal up to +24dBu. To prevent clipping, reduce

the level being sent from this equipment.

If you are unsure about the nominal operating level of the

equipment to which you will be connecting the DEQ230, refer to

the Reference Manual for that equipment.

Since the DEQ230 has two

channels, A and B, you can

connect two independent

sources. For example, you

could use channel A to EQ

the rhythm guitar and

channel B to EQ the bass

guitar. Or use channel A on

the kick drum and channel B

or the snare drum.

odern production values

sometimes lead to the heavy

use of compression during

the mastering process. When

rocessing CD audio, you

may find it necessary at

times to lower the Channel

evel of the active program

so as to avoid clipping the

output stage of the DEQ230.

This will allow additional

headroom for more

extensive equalization. See

g. 42 for details on the

Channel Level function.

ever place the equalizer

between the power amp and

the speakers, as the high-

owered levels created by

the power amp will damage

the DEQ230.
