Adjusting Equalization Bands and Balance
Precis DSP models provide a 10-band graphic equalizer to boost or cut the various frequencies (bands) for each output.
Each equalization band spans one octave and is identified by its center frequency. The bands are set for a flat response
(0 dB) at the factory. The adjustment range for each band is -12 dB to +12 dB. Balance is normally adjusted as part of
system setup and fine-tuning but can also be adjusted any time during operation.
Note: The button immediately left of the Reset button is used to toggle between the Tone and EQ sliders.
When the EQ sliders are visible, the button says Tone; when the Tone sliders are visible, the button says EQ.
To adjust equalization bands and balance for outputs:
1.
Using the CrossBar, route an input to all outputs needing adjustment.
2. From the main interface, select an output from the Output Device list.
3. Adjust the sliders for each equalization band until the desired sound is achieved.
If the equalization sliders are not visible, click the EQ button (the EQ button is only available when the Tone sliders
are visible).
4. Optional – Adjust the Balance slider.
5. Repeat Steps 1 through 4 for all outputs that require adjustment.
Tip: Any selected slider can be set to 0 dB (or to center for balance) by selecting the slider and typing “0”
(zero). All of the equalization bands for an output can be set to 0 (flat response) by clicking the Reset button.
