EQ (Equalizer)

This setting gives you a 4-band equalizer that you can use to shape the sound of your audio signal by cutting and boosting certain frequencies.

Varying levels of cut and boost for low, middle and high audio frequencies broken down as follows:

01 – 10: Lower values = attenuated highs and emphasized lows

11 – 20: Lower values = lower emphasized frequency

21 – 24: Lower values result in emphasized midrange 25: Flat EQ curve

26 – 30: Higher values = emphasized highs

31 – 40: Higher values = higher emphasized frequency

41 – 50: Higher values = emphasized presence and lows

Turns off the EQ.

NR (Noise Reduction)

This is a combination of two effects—hum elimination and noise reduction. Hum elimination works by cutting out the frequency that contains the hum (60Hz). Noise reduction works by gating the signal (muting the signal until its level rises above a certain point).

Noise Reduction (Right digit of display)
