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
The DEQ230 is a “line level” device, which means that it operates at a nominal level of
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 for the snare drum.
Never place the equalizer between the power amp and the speakers, as the high- powered levels created by the power amp will damage the DEQ230.
Modern production values sometimes lead to the heavy use of compression during the mastering process. When processing CD audio, you may find it necessary at times to lower the Channel Level 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 pg. 42 for details on the Channel Level function.
