2 Connections

Mono connections

This example shows how to connect the DEQ830 to one mono source. You can use this method to connect eight mono sources to the DEQ830. You would need eight insert cables to make all of these connections.

Stereo connections

Use two insert cables to connect the DEQ830 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 Channel 1 input and output of the DEQ830. Use another insert cable to connect the right main insert to the Channel 2 input and output of the DEQ830.

You can also simply connect the balanced main outputs of the mixer to the inputs of the DEQ830, 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 DEQ830 can operate in either a +4dBu or –10dBV setting. A rear panel switch allows you to configure the unit to your audio environment.

If you are unsure about the nominal operating level of the equipment to which you will be connecting the DEQ830, refer to the Reference Manual for that equipment.

22

Since the DEQ830 has eight channels, you can connect eight independent sources. For example, you could use Channel 1 to EQ the rhythm guitar, Channel 2 to EQ the bass guitar, Channels 3 and 4 to EQ the left and right outputs of a keyboard, and so on.

Never place the equalizer between the power amp and the speakers, as the high- powered levels created by the power amp will damage the DEQ830.

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 DEQ830. This will allow additional headroom for more extensive equalization. See pg. 32 for details on the Channel Level function.
