3 Basics of Equalization

Bypass mode

This mode is nearly as simple as it sounds: push the [BYPASS] button and the DEQ230 will let you hear the non-equalized audio. But there’s a bit more to it than that. There are also two gain adjustment stages that can be used to compensate for a reduction or increase in signal level caused by the equalization curve being used. The value for one of these stages (Channel Level) is saved along with the EQ settings when the program is stored; the value for the other stage (Master Level) is not. So what Bypass mode really is doing is causing the audio to “pass by” the processing stages that are stored as a part of the program.

Here is a diagram that shows the relationship of each of the stages in the DEQ230’s signal processing chain:

You’ll find a description of Channel Level mode further down on this page. For a description of the Master Level function, turn to page 45.

Audition mode

Audition mode allows you to choose specific programs and place them into the Audition List. From there you can more easily audition only those programs you want to hear for a particular audio source and "jump over" the ones you do not. To learn how to use this mode, see page 40.

Channel Level mode

If you are running two different instruments into channels A and B, you may be experiencing drastically different signal levels in each Channel. Channel Level mode can be used to adjust the output of channels A and B independently.

This mode is also useful when processing a stereo signal. If the combination of the source material and extreme EQ settings is causing the output of the DEQ230 to clip, Channel Level mode can be used to adjust the output of channels A and B simultaneously.

Unlike the Master Level function in Setup mode, the settings for Channel Level mode are stored with each program. To learn how to use this mode, see page 42.
