IMPORTANT: Be sure to set the attenuator control back
to its original setting (“F”) for normal operation. or a
subsequent user may think the unit is malfunctioning or
has a poor signal to noise ratio.
LO/MID/HI (bass/mid/treble) - HHVMC only
The HHVMC head includes VariMic
TM
equalization
adjustments to boost or cut the frequency response in
LOW, MID and HIGH ranges. The LOW and HIGH con-
trols will boost/cut by up to 8 dB while the MID control
will boost/cut up to 6 dB.

The controls are set to “zero”
(no boost or cut) in this photo
These controls operate as standard tone controls in
that a counterclockwise adjustment cuts the response
in that band and a clockwise adjustment boosts the
response.

Mic Capsule Adjustments
(EXPERT LEVEL ADJUSTMENT)
These adjustments significantly alter the gain and
tonal quality of the microphone, and are to be used
only in special circumstances.
Caution:
Always make the final decision about
sound quality with the windscreen in place.
Remove the windscreen using the supplied wrench.
Align flats on the wrench with flats on the capsule.
Attenuator Adjustment
The HHC & HHVMC heads include an attenuator in
the preamp circuitry to provide an additional 15 dB of
headroom when needed for extremely loud voices.
The attenuator should
ONLY
be used
when the gain
control is already turned all the way down
and the
audio is still driving the preamp into significant limiting
where both -20 and -10 dB LEDs stay lit all or most of
the time during peaks in the audio.

The attenuator control is a 16 position switch that
attenuates the audio in 1 dB steps. It is marked
0
through
F
where
F
is minimum attenuation and
0
is
maximum attenuation. Rotating it clockwise increases
the loudness, and counter clockwise decreases the
loudness.
