Alesis DEQ830 manual Retrieve Curve mode, Bypass mode, Channel Level mode

3 Basics of Equalization

works well for male vocals. Say you have two or three channels of male vocals feeding into the DEQ830. To EQ these, just retrieve the curve from the Curve Bank, apply it to each male-vocal channel and modify it slightly to fit each particular vocal.

For information on how to do this, see page 41.

Curve 00 is a “flat” curve. We recommend that you leave Curve 00’s gain settings at 0 so that you may use it as a “clean slate” for building new curves from the ground up.

Retrieve Curve mode

This mode allows you to take a stored EQ curve from the Curve Bank and place it into the currently selected channel or Link Group. For information on how to do this, see page 41.

Bypass mode

This mode is nearly as simple as it sounds—pushing the [BYPASS] button 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.

The following diagram shows the relationship between each of the stages in the DEQ830’s signal processing chain.

Channel Level mode

When you run a number of different instruments into the DEQ830, each channel may experience drastically different signal levels. Channel Level mode can be used to adjust the output of each channel 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 DEQ830 to clip, Channel Level mode can be used to adjust the output of two stereo channels simultaneously. To do this, the two channels must be linked. See page 42 for more details on Link mode.

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 44.

Unlike the Master Level function in Utility mode, the settings for Channel Level mode are stored with each curve or program. For more on Channel Level mode, see page 41.
