UCR 100

UCR 100: UHF Compact Receiver  
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.
