Figure 13 shows details of the channel strip signal processing section. Features of the
processing section are as follows.

Input gain trim: the slider on the right sets the input gain to the processing section, it has
a range of –20 to +30 dB of gain. This control should be the first step in balancing a mix
since it will facilitate managing mix minus and program levels. Beside the gain trim
control is a meter indicating signal presence and level, it measures at the channel strip
input before the fader or any plugins. Only one meter bar is displayed, on a stereo input
strip it will indicate the level of the sum of the 2 input signals.

De-noiser: The denoiser removes unwanted broadband noise and is tailored for use on
dialogue. The knobs adjust the depth of the denoising in the high and low frequency
bands, with a range of 2dB to 18 dB. The "Noise" button turns the processing on and
off. The slider on the left adjusts the overall degree of the de-noising from 0dB to –40
dB. The meter bar indicates the instantaneous amount of the de-noising.

De-esser: The de-esser has a range of 2dB to 18 dB attenuation adjusted by the
"Depth" knob. The Frequency knob adjusts the de-essing corner frequency from 500 to
4 KHz. The "Ess" button turns the processing on and off. The slider at the left adjusts
the de-essing threshold. The meter bar indicates the instantaneous amount of the de-
essing.

Leveler: The Leveler is a compressor with a low fixed ratio and release time. It is
designed to gently smooth out the peaks in a wide range of signals. The slider on the
left adjusts the limiting threshold from 0 dB to -40 dB. The Attack knob sets the attack
time over a range of 4ms to 100 ms. The Gain knob provides makeup gain over a range
0dB to 20 dB. The "Lvl" button turns the processing on and off. The meter bar indicates
the instantaneous amount of gain reduction.

Equalizer: The 3 band semi-parametric equalizer operates over the following ranges:
o
LOW: +/-15 dB boost/cut over range 40 Hz to 400 Hz, bell response
o
MID: +/-15 dB boost/cut over range 200 Hz to 4 kHz, bell response
o
HI: +/-15 dB boost/cut over range 800 Hz to 15 kHz, bell response

High Pass Filter: 12 dB/octave filter adjustable from 200 Hz to 1 KHz
