MX50 OPERATORS’ MANUAL 6
CONTROL DESCRIPTION AND OPERATION
Both channels of the MX50 are identical and may be used completely independently or
linked for stereo operation. In the linked mode, the left and right channel control settings
are averaged, though the channel bypass switches remain independent. In linked mode,
both de-essers of the two channels track together to avoid the inevitable image shifting
that would occur if the stereo signal were treated independently.
Frequency This control determines the lower range of the frequency band
used to detect sibilance and should ideally be set as high as
possible while still allowing the de-esser to react to sibilant
program sounds. This will vary from voice to voice, but will usually
be around 3 to 4kHz.
The control is continuously variable from 800Hz to 8kHz and
covers the full sibilant range, including the hard sounding
harmonics or other side effects that can be generated when treble
frequencies are boosted or enhanced in some way in an attempt to
add more definition to low frequency.
De-Ess This rotary adjusts the amount of gain reduction that will take place
when a sibilant sound has been detected, up to a maximum of
20dB, this can be seen on the G.R. meter. Using large amounts of
gain reduction may cause very obvious artifacts, especially on
broadband mixes, so de-ess individual tracks where possible, and
choose Split Band mode for the least obtrusive processing.
This control uses floating threshold circuitry which tracks the signal
level so that the same setting can be used for signal levels over a
40dB range.
GR Display Shows how much gain reduction is being applied. In Full Band
mode, the gain reduction is applied to the whole signal, while in
Split Band mode, only frequencies above the value set on the
Frequency control are attenuated.
Air The AIR switch allows frequencies above the sibilant band (above
12kHz) to remain unaffected by De-Essing, thus preserving upper
harmonics and greatly increasing the transparency of signals
undergoing de-essing. Normally we would recommend leaving this
switch depressed (In).
