Of the 31 bands, each fader controls each band increase / reduce filter signal level. The maximum
increase / reduce of its central frequency is ± 15 dB. When the signal level has been adjusted, the curve
of the attenuator is the EQ’s frequency response.
NOTE: When adjusting, the level between neighboring frequency points, there should not be a wide
discrepancy, it usually doesn’t exceed 3 dB.
4. Feedback Frequency LED
There are 31 frequency LEDs. When any frequency display of the sound field produces feedback, its
feedback LED can accurately show it to you, and you can attenuate the frequency to non-feedback.
5. Output Signal VU Meter
This meter is a multi-step LED; The green LED shows –20, -15, -10, 0, +10dB, orange LED shows
+15dB and red LED shows +20dB. The accurate level indication allows you to monitor the output signal
