Lectrosonics UT200c - Manual (Page 6)

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. There is also an attenuation adjust­
ment to provide up to 15dB of additional headroom if needed.
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 controls 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 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 high end so a little cut
does not ruin the response.
• Treble boost might be fine on some sound systems. The sound doesn’t get harsh
(showing that the response was smooth) but sibilants are a little too much.
Should be used in moderation.
Bass Filter
In addition to the tone controls, the UT200C 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 too late. To solve this problem, the VariMic has a low frequency filter that is so sharp that it
can remove low frequency noise without affecting any wanted vocals. It consists of a 36 dB per octave filter circuit to
sharply remove low frequency noise below 75 Hz without affecting vocal fundamentals. The lowest operatic bass voice
fundamental is 82 Hz. See the curve below.
Attenuator UT200 Bass/Midrange/Treble Boost/Cut
The VariMic head includes an attenuator to provide an
additional 15dB of headroom when needed. The attenuator
should only be used when the normal Mic Level pot is
already turned down as far as it will go and the signal
through the mic is still too hot. The attenuator control is a
16-position switch marked 0 through F. “F” is minimum +10
