Description

Overview

The DBSMD dual battery digital bodypack is a wideband transcoder that's fully compatible with DSQD, DCHR, and DCR822 receivers and configurable as either a transmitter or a recorder. It's got a tuning range of 470 to 608 MHz, covering both A1 and B1 and selectable 10/25/50 mW RF power. The TA5M mic/line connector also acts as a time code input. The high-density transmission mode allows as little as 2mW between frequencies for tighter channel spacing. The DBSMD is the same shape and size as SMWBD, so it's compatible with the same accessories.

The DBSMD digital transcorder is developed specifically for the needs of the film industry and offers time code jam sync capability, 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 unit features 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.

The input section features the Lectrosonics servo bias input circuitry with a standard TA5M type jack for use with electret lavalier 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 acousti- cally transparent while maintaining low distortion of brief transients and longer duration peaks.

A water resistant control panel with LCD, membrane switches and multi-color LEDs make input gain adjust- ments, frequency and compatibility mode selection quick and accurate. The battery compartment accepts indus- try-accepted AA batteries (lithium recommended). The housing is machined from solid aluminum 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

Consumer Alert

Starting in 2017, the 617-652 MHz and 663-698 MHz frequencies are being transitioned by the Federal Communications Commission (FCC). Users of wireless microphone devices that operate in any portion of those frequencies must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
