6Setting DSP Parameters

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

 

From this page, you can adjust settings in the DSP. The appliance uses traditional processors (for example, Compressor, Noise Gate, Graphic Equalizer) for audio signals in the digital domain.

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 four analog input, one network input, and one analog output channels.

Select if the analog input channels use Line or Mic input. For Ana­log 1, AES is also an input option. (See Selecting Input Type, Gain, and Phantom Power.)

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

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

Selecting the Menu button for 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.

High/Low Pass

Sets the band of frequencies that will pass through the high pass and low pass filters and select the type of filter that is used.

Limiter

Prevents a signal from exceeding an adjust­able 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 allow 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.

Signal Present

Illuminates green when audio is present in the channel input.

 

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