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).
Hum Elimination (Left digit of display)
Increasing levels of hum elimination (60Hz harmonic notch filters)
Turns off hum elimination
Noise Reduction (Right digit of display)
Increasing levels of gate threshold.
Turns off noise reduction
Indicates both hum elimination and noise reduction are turned off.
