The Lectrosonics UH400 is a UHF plug-in transmitter compatible with all receivers in the 100, 200 and 400 series. Digital Hybrid Technology is a DSP-based architecture that digitizes the audio signal on input and eliminates analog compandors, and the noise associated with them. The result is pristine, noise free audio and an analog FM signal link provides greater range than fully digital wireless systems.
Two rotary switches access 256 frequencies in standard Lectrosonics frequency blocks. Ultra low noise op-amp ensures quiet operation and high headroom. Phantom power is selectable for 5V, 15V and 48V for condenser and electret condenser microphones. The locking collar prevents the unit from accidentally falling off the microphone and the input gain is adjustable over a 43dB, allowing flexible impedance matching. The unit is powered by a single 9V battery and provides a full 100mW output over the life of the battery.
