Lectrosonics DBSM E01 single battery digital transmitter
The Lectrosonics DBSM E01 single battery digital transmitter has been developed specifically for the needs of the film industry and offers time code jam sync capability.
The transmitters offer hands-free setup and adjustment using audible tones and can be put to sleep to conserve battery power during setup while buried inside costuming, then awakened for normal operation when the production begins.

- DCR822 Digital Dual Receiver
- DCHR Digital Dual Portable Receiver
Other features include input gain adjustment in 1 dB increments over a 44 dB range and adjustable low-frequency audio roll-off for 3 dB down points at 20, 35, 50, 70, 100, 120 or 150 Hz to control subsonic and very low-frequency audio content. The transmitters also offer selectable output power of 10, 25 and 50 mW. A special high-density (HDM) transmit mode at 2 mW allows for ultra-tight channel spacing without concern for frequency coordination.
The input section features the unique Lectrosonics servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed ahead of the first mic preamp to protect the entire audio chain from overload. The limiter has a range of more than 30 dB for excellent overload protection, and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion of brief transients and longer duration peaks.
A water resistant control panel with LCD, membrane switches and multi-colour LEDs make input gain adjustments, frequency and compatibility mode selection quick and accurate. The battery compartment accepts industry accepted AA batteries (lithium recommended).
- Wideband: A1B1 470-614MHz or B1C1 563-691MHz
- Selectable output power to maximise operating range or battery life
- Ultra-lightweight, corrosion resistant housing
- OLED interface with lockout option
- Servo Bias input circuitry
- IR (infrared) port for fast setup
- Alternate use as recorder on internal microSDHC memory card
- Timecode jam-sync capability with TCXO for <1 ppm accuracy
- High density mode for ultra-tight channel spacing
The housing is machined from solid aluminium blocks to provide an extremely lightweight and rugged package. A special non-corrosive finish resists salt water exposure and perspiration in extreme environments.
Frequency Tuning Range
RF-intense multichannel and mobile venues must have a broad selection of frequencies available to alleviate interference problems, especially with the emergence of DTV telecasts. Frequencies are selectable in 25 kHz steps across the broad tuning range of each frequency band.
Alternate Recording Function
Instead of transmitting, the transmitters may also be used as a stand alone recorder. The industry standard .wav (BWF) file format is compatible with essentially any audio or video editing software.
NOTE: The transmitting and recording functions cannot be used simultaneously. Users must choose to transmit or record.
