CHANNEL EQ EQUALIZER1243
HPF Freq
The High Pass filter (HPF) removes low frequencies from the signal, resulting in a thinner sound. The HP filter slope
has a 18 dB/Octave roll-off.
D Set the desired cutoff frequency for the high pass filter.
Range: 20 Hz - 4 kHz
LPF On
D Click the On button to activate the low pass filter.
LPF Freq
The Low Pass filter (LPF) removes high frequencies from the signal, making the sound less bright. The LP filter has
12 dB/Octave roll-off curve.
D Set the desired cutoff frequency for the low pass filter.
Range: 100 Hz - 20 kHz.
The Equalizer section
The Equalizer section features a four-band EQ with parametric midrange controls and high and low frequency shelv-
ing bands. The EQ can be switched between two operating modes, each with slightly different curve characteristics.
The Equalizer has the following parameters:
LF Gain
The LF section provides low frequency shelving equalization. All frequencies below the set LF Frequency will be cut
or boosted by the set LF Gain amount.
D Set the LF Gain/Attenuation amount.
Range: +/- 20 dB
LF Frequency
D Set the LF Frequency.
Range: 40 Hz - 600 Hz
LF Bell
D Click the LF Bell button to switch the LF EQ to peaking characteristics.
This means it works like a regular parametric EQ band, cutting or boosting the signal around the set LF Frequency.
Bell mode has a fixed bandwidth or "Q" value.
