    Configuring the Nyquist AoIP Gateway The Nyquist GA400P AoIP (Audio over IP) Gateway provides the ability to receive an analog signal, convert it to a digital signal, and send it to a partner device across a net- work. It can also receive a digital signal over a network, convert it to an analog signal, and play it back through a speaker.

    Table 8. DSP Page OUT VU meter Indicates the strength of the network send signal. Input Gain Adjusts the strength of the analog input signal. The DSP features that can be applied to a channel, accessible through the DSP Features menu, are described in the following table.

  • Page 23: Knob Adjustments

    Tip: For best results, use the vertical slider to adjust the input level until you have a strong signal (i.e., within the green and yellow areas on the meter), then adjust the final output levels using the DSP Outputs controls. To adjust the channel volume level: On the appliance Web UI’s main page, select DSP.

  • Page 24: Adjusting Input Gain

    Mute button will illuminate red. You can click the Mute button again to unmute the channel. • Adjusting Input Gain Because input signal levels can vary greatly based on the attached device, you will want to adjust the Input Gain for a channel to ensure the input signal level is high enough to use, but not so high that it sounds distorted.

  • Page 25: High/Low Pass

    If Channel Volume Is Too High If a channel is not clipping but the channel slider level control must be set below the −20 dB position to achieve the proper volume level, the Input Gain control setting is too high. Set the channel slider control knob to the 0 dB position and adjust the Input Gain control until the desired volume level is achieved.
  • Page 26 To adjust the high/low pass parameters for a channel: On the appliance Web UI’s main page, select DSP. Select the Menu button for the channel. From the drop-down menu, select High/Low Pass. Note: If you want to return to the factory settings, select the Reset icon that appears in the right corner.

High/Low Pass Parameters (Continued) Low-Pass (High Cut) This feature helps eliminate high-frequency noise (signals of 8000 Hz and above) such as background hiss and sibilance (excessive "S" in vocals, etc.) and is used primarily with microphone-level input. It is particularly effective when handheld microphones are used.
