UCR 100

UHF Compact Receiver
The Lectrosonics 100 system was designed to operate
with the new generation of DV camcorders, offering an
ultra-compact receiver and modest cost, yet preserving
the performance that has become the hallmark of Lectrosonics.
The system offers 256 selectable frequencies over a 25.6
MHz band to avoid interference from local RF sources.
The UCR100 receiver is highly sensitive and the matching
transmitters provide a full 100mW of output power. The
result is exceptional operating range and freedom from
drop outs.
The audio signal processing circuitry and audio quality of
the 100 Series system rivals much more expensive wireless
systems. Wide range input limiting in the transmitters
prevents overload distortion from high audio input levels.
The result is extremely low noise and distortion, and
audio quality that is at home with the finest microphones
and post-production facilities.

The audio output level is controlled by a front panel knob
that is easy to reach in most mounting situations. The
knob is used to adjust the output level of the receiver to
optimally match the input levels of camcorders, mixers
and other sound system components. The output is nominally
at 0dBv (line level), but will also match microphone
level inputs on camcorders by using an adapter cable offered by Lectrosonics. Two front panel LEDs indicate the
level of the audio signal.
An extremely durable, tempered alloy 1/4 wavelength
antenna is ideally matched to the tuning range of the
receiver. A special insulation on the antenna keeps it
semi-rigid and oriented away from the housing to maximize
reception.
The UCR100 Receiver is housed in an rugged, lightweight,
compact, machined aluminum package for lasting performance
in abusive environments. Floating battery contacts
compensate for the wide variety of different brands of 9 Volt
batteries. The attached, aluminum battery door rotates to
open, but cannot be opened accidentally.
