6.10Adjusting 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.
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.
To adjust the parametric equalizer settings for a channel:
Step 1On the appliance Web UI’s main page, select DSP.
Step 2Select the Menu button for the channel.
Step 3From the drop-down menu, select Parametric EQ.
Note: If you want to return to the factory settings, select the Reset icon that appears in the right corner. |
Step 4Adjust frequencies as desired, ensuring the Enable LEDs are green for each selected frequency. You can adjust the frequencies by moving the Freq knob or by double-clicking the knob and typing the frequency. When typing the frequency, only numeric values from 20 to 20,000 can be entered.
Step 5Make desired Q adjustments by adjusting knob (or double-clicking and typing the desired adjustment. Q can be from 0.1 to 20 and sets how wide to either side of the selected frequency the adjacent frequencies are affected.
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.
Step 6For each frequency, use the Gain knob or double-click the knob and type the gain to either boost (turn up_ or cut (turn down).
Gain knobs can be moved between +12 or -12 dB. By default, each knob is set at 0 dB, which means that no frequencies are being boosted or cut.
Step 7Select Save Settings to Server.
