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

 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 pointer is between the 

darkened dots.

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 

where 

is minimum attenuation and 

0

 is 

maximum attenuation. Rotating it clockwise increases 

the loudness, and counter clockwise decreases the 

loudness.
