Figure 4-10 Limiter Config Window

Threshold specifies the input bargraph level which is considered to be an overload condition; any time

an input signal exceeds this level, the gain will be decreased for that input until it no longer exceeds the

Threshold. The Threshold options are -6dB (highest), -9dB, -12dB, and -15dB (lowest). The -9dB

setting is recommended for most applications. In general, Threshold settings lower than -9dB will

provide better overload protection, but with significant sacrifice in peak signal level (dynamic range).

The Link option is provided in Stereo Input Modes to give the user the option of making the input

channels Linked or Independent (In Mono configuration, the extra inputs are used only with the

Reference Canceller, and are always Linked). When Linked, the Limiter gains are equal at all times for

all channels, and are reduced in response to an overload on any input channel. When Independent, the

Limiter gains are not necessarily equal, each reduced in response to only its own input channel. For

stereo or multiple microphone applications, the Limiter inputs should be Linked to avoid annoying

Left/Right differential gain shifts and loss of stereo perspective; however, Independent Limiter gains

should be used when processing two unrelated monophonic signals in a Stereo Input Mode.

When the limiter is active, red markers will appear in the Input Level bargraphs on the Master Control

Panel. These markers indicate the limiter threshold setting.
