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

  • Page 22: Figure 8, Dsp For Single Channel Bridged Mode

    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. Note that if your appliance is operating in single channel bridged mode, you will see only one Network channel.

  • Page 23: Setting The Channel Level

    DSP parameters and the Mute and Level buttons are described in the following table. Table 7, 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.

  • Page 24: Signal Led, Clip Led, And Vu Meter

    place the mouse over the slider, the numerical value of the level appears. Signal LED, Clip LED, and VU Meter To the right of the Channel Level control are the Signal and Clip LEDs and the VU meter. The green Signal LED automatically illuminates when a signal is being received.

It is particularly effective when hand held microphones are used.

  • Page 31: Adjusting The Limiter

    Adjusting the Limiter A limiter is a compressor with a high slope that is used to prevent a signal exceeding a set decibel level. Limiters are used as safeguards against signal clipping. Limiter parameters are set per channel. Figure 12, Limiter Settings To adjust the limiter settings for a channel: Step 1 On the appliance Web UI’s main page, select DSP.

  • Page 32: Adjusting Noise Gate Settings

    Table 10, Limiter Settings (Continued) Decay Sets the rate for turn off of the limiter after the signal is below the threshold. Decay range is 5 to 2300 milliseconds. RMSTC Sets how fast the limiter reacts to the above threshold signal. RMSTC range is 50 to 10000.
