6Setting DSP Parameters

When you select DSP from the appliance’s web UI, the DSP page appears.

From this page, you can set parameters for DSP, which is a form of processing that uses bit data to simulate characteristics found in analog circuits. With DSP, you can alter analog signals, such as audio or video signals, that have been converted to a digital format.

The DSP page shows Mute and Level selections for four input chan­nels and allows you to do the following:

View Signal and Clip LEDs for each channel.

Set the channel level for the six input and two output channels.

Select if the input channels use Line or Mic input. (See Selecting Input Type, Mic Gain, and Phantom Power.)

Set Mic Gain for an input channel using Mic as the input. (See Selecting Input Type, Mic Gain, and Phantom Power.)

Control Phantom Power for any channel using Mic as the input.

Selecting the down arrow next to a channel number displays a menu of other parameters. Some of these parameters affect all channels, in which case a channel number does not appear on the top of the graphic. If a parameter affects only the selected channel, a channel number appears on the selected parameter graphic.

DSP parameters and the Mute and Level buttons are described in the following table.

Table 6, DSP Page

Mute

Silences the audio for the selected channel.

Level

Adjusts the channel volume level in 1 dB increments.

Compressor

Lessens the dynamic range between the loudest and quietest parts of an audio signal.

Ducker

Lowers, or ducks, the output of a channel when another signal is encountered.

Graphic EQ

Uses fixed frequencies to tailor the frequency content of an audio signal.

Limiter

Prevents a signal from exceeding a certain pre-set maximum level.

Noise Gate

Eliminates low-level hiss, noise, or leakage, particularly when there is a high level of ambient noise.

Parametric EQ

Uses a center/primary frequency to all tailor­ing of the frequency content of an audio sig­nal.

Router

Routes audio to different devices.

Settings

Allows you to provide names and colors for the input and output channels.

Status

Provides real-time status of the selected channel.

 

You can set Limiter parameters for the output signal or set global Ducker and Router settings by selecting the option you want from the drop-down menu available for the output.
