Description
The DBSM and DBSMD digital transcorders were developed specifically for the needs of the film industry and offer time code jam sync capability. They 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. 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 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).
The DBSM and DBSMD use the same accessories as the SMWB and SMDWB transmitters, specifically belt clips, pouches, and battery eliminators.
