Lectrosonics UT300VM - Manual (Page 8)

Internal Controls - VariMic Version
Caution - Due to the high RF levels surrounding the transmitter, the sound of the Varimic
capsule may be temporarily affected if the metal windscreen is not in place. Always make the
final decision about sound balance and quality with the windscreen in place.
The VariMic head includes adjustments for Bass, Midrange and Treble response,
and for an attenuation adjustment to provide up to 15dB of additional headroom if
needed. Unscrew the windscreen for access to the VariMic controls.
Bass / Mid / Treble
The bass and treble controls will boost/cut by up to approximately 8dB while the
Mid control will boost/cut up to about 6dB. These pots operate as standard tone
controls. Counter-clockwise will reduce the response in that band and clockwise
will provide a true boost. These controls can be accessed by removing the
windscreen. To remove the windscreen, grasp the body of the transmitter in one
hand and the windscreen in the other hand. Carefully unscrew the wind-screen
counter-clockwise until it comes off then carefully slide the windscreen past the
mic element.
• Set flat, the mic capsule is very wide range and sounds a lot like a large
competitor’s top line condenser mic.
BASS MID TREBLE
• Bass cut gives a dry but highly intelligible sound. Crisp.
• Bass boost “fattens” the sound but is very listenable.
Does not get midbass boomy.
• Midrange cut sounds very smooth. Almost a “crooner”
quality. A sweet sound.
• Midrange boost is likely to be useful in a system that is
midrange shy.
• Treble cut has a “mellow” sound. The capsule has a solid

• Treble boost might be fine on some sound
systems. The sound doesn’t get harsh

In addition to the tone controls, the UT300

also has a built in bass filter. This filter is fixed

and cannot be adjusted or defeated. Low frequency noise is much more of a problem
with wireless microphones than with conventional microphones. With a regular mic,
low frequency wind noise, breath thumps or handling rumble can be filtered out at the
control board before the noise causes problems with the following electronics or
speaker systems. But with a wireless microphone, the electronics that will be
overdriven are right in the wireless microphone. Filtering at the control board is much
