The Lectrosonics UCR411 is a portable, camera mountable receiver designed for professional audio applications in the field or indoors. The receiver is completely compatible with all 400 series wireless transmitters and provides 256 selectable UHF frequencies across a 25.6MHz tuning range. Smart Diversity reception reduces RF interference and dropout and a built-in RF spectrum analyzer searches across the entire 25.6MHz tuning range, locating the strongest possible frequencies in the area. The clear frequencies are marked and displayed on the backlit LCD. Balanced XLR output provides maximum output gain with minimal noise and the receiver is powered with internal 9V batteries or external DC power supply.

The Lectrosonics LMa Beltpack Transmitter incorporates their patented Digital Hybrid Technology and an improved audio input signal path. The wireless beltpack transmitter is completely compatible with any of the Lectrosonics Digital Hybrid receivers and features a TA5-male input connection for lavaliers, instrument pickup cables and line level signal.

Digital Hybrid Technology combines a 24-bit digital audio chain with an analog FM radio link that eliminates compandor circuits and any associated noise. In addition, analog compandor emulation allows the transmitter to work with third-party and Lectrosonics 100, 200 and IFB series wireless systems.

An improved audio input features Servo Bias Wiring, which reduces overload and eliminates the need to introduce pads on certain microphones. Standard in most Lectrosonics wireless beltpacks are 256 selectable frequencies, versatile battery compartment that accepts any 9V battery and a rugged die-cast metal enclosure.

The M152 is a highly sensitive Omnidirectional Lavalier Microphone featuring a wide frequency response that accentuates the presence and character of the human voice. The M150's frequency response is measured at 20Hz to 20kHz with a slight rise around 10kHz, resulting in a brighter, more "airy" response. A low frequency dip around 50Hz reduces noise caused by proximity effect and ambiance. The omni-directional polar pattern provides a generous response at the direct and off-axis sections of the microphone capsule.
