Product Description

The Lectrosonics 400 Series wireless microphone system combines digital hybrid technology, diversity reception, and rugged components to achieve clear audio signals at long range. This system includes a camera-mountable receiver, beltpack transmitter and omnidirectional lavalier microphone.

The Lectrosonic UM400 implements Digital Hybrid Wireless  technology in a classic Lectrosonics belt-pack transmitter. A 5-pin input jack provides taps for low impedance dynamic mics, electret lavalier mics with positive or negative bias and line level inputs. Input gain is adjustable over a 43 dB range to perfectly match the audio input level for optimum modulation, minimum distortion and maximum signal to noise ratio. Input levels are accurately indicated by two LED’s on the control panel.
