  • Page 21: Setting Dsp Parameters

    Setting DSP Parameters When you select DSP (Digital Signal Processing) from the appliance’s web UI, the DSP page appears. This page presents a mixing board interface, allowing you to monitor, con- trol, and perform DSP operations on the signal of the input and output channels. Note: Digital Signal Processing (DSP) refers to the digital operations that are performed to modify or control the digital signal.
  • Page 22 Figure 8. DSP Page The DSP page displays a mixing board console containing five input strips and one output strip. Each strip controls the audio signal for a given channel, providing muting, input/output levels, signal processing, and more. Signal processing includes traditional audio processing, such as compressors, noise gates, equalizers, and more.
  • Page 23 • Adjust Input Gain level for each analog input channel. (See "Selecting Input Type, Input Gain, and Phantom Power” on page 22.) • Control Phantom Power for any channel using Mic as the input. (See "Selecting Input Type, Input Gain, and Phantom Power” on page 22.) Selecting the DSP Features button at the top-right corner of a channel displays a menu of DSP features for that channel.

  • Page 24: Table 8, Dsp Features

    Table 7. DSP Page Line/AES/Mic Determines whether the input signal coming from the channel’s input jack is at line or microphone level, or if it is encoded as a digital AES signal. Phantom Power Determines if phantom power is being provided to the input microphone.

  • Page 25: Setting The Channel Level

    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. Figure 9. DSP Output Options Setting the Channel Level The Channel Level control is a vertical slider that is adjusted in 1 dB increments and con- trols the output level for the channel.

  • Page 26: Muting A Channel

    Muting a Channel You can mute a channel to cut off an audio signal and stop the input signal from being sent to the output channel. Note the input signal will still be visible on the IN meter, but the OUT meter will show that nothing is being forwarded to the output channel. To mute a channel: On the appliance Web UI’s main page, select DSP.

  • Page 27: Troubleshooting Gain Structure

    Note: Phantom power is only used by devices that contain active electronics, such as con- denser microphones and many direct boxes. It uses a balanced signal, which renders it effectively invisible to balanced microphones that do not use it. When enabled, +15V of balanced phantom power is available on pins 2 and 3 of the XLR connector or the +/- ter- minals of the Phoenix connector.

  • Page 28: Adjusting Compression Settings

    If the signal cannot be increased with the Input Gain knob at 2–3 o'clock, make sure the input is not set to Line. Note: Some microphones are very low output. The mixer will not be able to completely compensate for the low level but will be able to provide a usable output signal. A decent dynamic microphone output level is approximately -55 dB.

  • Page 29: Table 9, Compressor Settings

  • Page 33: Setting High Pass/Low Pass Parameters

    By default, each knob is set at 0 dB, which means that no frequencies are being boosted or cut. Note: For the best results, frequencies should be cut only. Boosting frequencies to com- pensate for room dimensions or speaker response deficiencies usually results in a loss of headroom in the signal chain.

  • Page 34: Figure 13. High/Low Pass Parameters

    You can specify the range of frequencies that will pass through the high pass and low pass filters and select the type of filter that is used through the channel’s High/Low Pass drop-down menu option. Figure 13. High/Low Pass Parameters To adjust the high/low pass parameters for a channel: On the appliance Web UI’s main page, select DSP.

  • Page 35: Table 11, High Pass/Low Pass Parameters

    Table 11. High Pass/Low Pass Parameters High Pass (Low Cut) This feature helps eliminate low frequency noise (signals of 100 Hz and below, such as background rumble from ventilation systems, etc.) and is used primarily with micro- phone level input. It is particularly effective when hand held microphones are used. Frequency Set the cutoff frequency.

  • Page 36: Adjusting The Limiter

    Table 11. High Pass/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.

  • Page 39: Adjusting Noise Gate Settings

    Adjusting Noise Gate Settings A noise gate controls the volume of an audio signal by attenuating the signal when it reg- isters below the threshold. This is typically used to eliminate or minimize background noise. Figure 15. Noise Gate Settings To adjust the noise gate settings for a channel: On the appliance Web UI’s main page, select DSP.

  • Page 40: Table 13, Noise Gate Settings

    Table 13. Noise Gate Settings Enable Enables or disables the noise gate DSP effect for this chan- nel. Threshold Sets the minimum threshold level that the signal must reach for the noise gate to “open”, allowing the signal to be sent to the output channel. Threshold range is -135 to +21 db.

  • Page 41: Adjusting Parametric Equalizer Settings

    Adjusting Parametric Equalizer Settings A parametric equalizer is a multi-band variable equalizer that allows control of frequency amplitude (boost/cut), center frequency, and frequency bandwidth, or Q. Figure 16. Parametric Equalizer Settings The parameter equalizer settings for your device allows you to adjust the Q and gain for seven separate frequencies, which then become plot points on the screen’s graph.

  • Page 42: Adjusting Router Settings

    Q is the Quality or Quality Factor, which refers to the bandwidth of one band of a parametric equalizer. Q is calculated by dividing the center frequency in Hz by the width of the boost or cut zone, +3 dB or -3 dB above or below 0 dB. For each frequency, use the Gain knob or double-click the knob and type the gain to either boost (turn up) or cut (turn down).
