The 4 DBu Digital Encrypted Bodypack Wireless System from Lectrosonics is a compact, professional two-channel wireless solution designed for broadcast, film and television production, live performance, rental, and house-of-worship applications.The DBu transmitter is a 4th-generation digital design featuring specially developed, high-efficiency circuitry for extended operating time on two AA batteries. The transmitter tunes in coarse or fine steps across the UHF television band from 470608 MHz (470614 MHz for export versions) with selectable 25 mW or 50 mW RF output power. A pure digital architecture enables AES-256 CTR encryption for high-level security applications.The top panel includes the antenna jack, audio input jack, audio level LEDs, and a programmable function switch. Red/green LEDs indicate audio levels from 20 dB through the onset of limiting for precise input gain adjustment. The programmable switch can be configured for mute, power on/off, talkback, or bypass operation.Studio-quality audio performance is achieved through premium preamp components, wide-range input gain control, and DSP-controlled limiting. Input connections and settings support lavaliere microphones, dynamic microphones, and line-level sources. Input gain is adjustable over a 44 dB range in 1 dB steps, allowing precise matching to the input signal to maximize dynamic range and signal-to-noise ratio.The DSQD receiver delivers ultra-low-latency digital audio with extended operating range, continuously tunable tracking filters, and both analog and digital audio outputs. Rear-panel antenna inputs with loop-through capability support remote antenna systems, with optional front-panel antenna mounting available.Main Features:Built for uncompromising RF stability.Rugged and Durable.Operates over entire UHF range (470-608).Academy award winning sound.Ultra-low latency.RF performance you can bet the show on.Designed and built in the U.S.A.What’s Included:1 Lectrosonics DSQD 4ch Digital Wireless Receiver with Dante4 Lectrosonics M152-5P Omni Lavalier Mics, TA5F Connector4 Lectrosonics DBu Wireless Bodypack Transmitters1 Lectrosonics RMPM2T-1 Rack kit for single DSQD receiver2 Lectrosonics ARG15 15′ Cable, Mini Coax BNC-BNC2 Lectrosonics ALP500 Antenna LPDA, Shark Fin StyleSpecifications:Frequency Selection: Selectable; 100 kHz or 25 kHzRF Power Output: Selectable; 25 mW or 50 mWFrequency Stability: 0.002%Digital Modulation: 8PSKFrequency Response: 40 Hz 20 kHz (1 dB)Input Compressor: Dual-envelope compressor, >30 dB rangeGain Control Range: 45 dB, semi-log menu-driven control, 1 dB stepsLow-Frequency Roll-Off: Selectable 3 dB @ 35 Hz, 50 Hz, or 70 Hz 36 dB/octave slopeModulation Indicators: Dual bi-color LEDs indicate 20, 10, 0, and +10 dB (referenced to full modulation) LCD bar-graph modulation indicator.Operating Temperature Range: 20 C to +50 C (5 F to +122 F)
