The DBSM and DBSMD digital transcorders were developed specifically for the needs of the film industry and offer increased battery efficiency, time code jam sync
capability, 3 RF power settings, D2 and HDM compatibility modes, and the famous SM Series durability and form factor. Their ultra small size makes them perfect for theatre where we are always trying to hide the packs.

Gain adjustment is in 1 dB increments over a 51 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 audio content. 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 OLED, membrane switches and multi-color LEDs  make input gain adjustments, frequency and compatibility mode selection quick and accurate.

The battery compartment accepts industry-accepted AA batteries
(lithium recommended).
