Next-Generation Professional Wireless Transmitters from Lectrosonics

0Share

Lectrosonics’s SM Series of miniature wireless transmitters are well known for their transmission range, signal clarity, and dependability in the field—this is what makes them such enticing audio gear for professional film shoots. Now Lectrosonics is upping the ante again with its DBSM transmitters/recorders, giving users a wider frequency range, tighter tuning, incredibly accurate and long-lasting timecode sync, extended battery life, and more.

These new transmitters come in two variants: the DBSM, powered by a single AA battery, and the DBSMD, powered by two AA batteries. They are compatible with many receivers in the Lectrosonics ecosystem, including D Squared, DCR822, DCHR/DCHT, and Duet systems. This new generation of transmitters was built with cross-compatibility in mind. Lectrosonics knows the needs of customers are various and wide—and this cross-compatibility ensures dependable performance, whether you’re using the transmitters for film and television production, or live concert entertainment.

With a tuning range that covers the A1 and B1 bands—or up to 614 MHz for the international E01 variant—these transmitters provide a tight channel spacing of 200 kHz. In laymen’s terms, this means you’ll have double the operating frequencies over the previous generations of transmitters. Battery life has been upgraded, as well. Depending on the model, the battery type, and the selected RF output power, the SM series transmitters will give you up to 18 hours (DBSMD) or nearly 9 hours (DBSM) of continuous use.

Each transmitter can operate at three different RF power ratings in D2 mode: 10, 25, or 50 mW. The higher the rating, the longer your range. The new HDM (High-Density Mode) runs at 2 mW RF power and affords you more than 24 channels in just 6 MHz of bandwidth.

This transmitter employs 100% digital architecture and AES-256 encryption, with 24-bit/48 kHz specs to ensure editable broadcast-quality audio. Furthermore, as an alternative to working as transmitters, the DBSM and DBSMD can accept a microSD card for onboard, direct recording in standard WAV (BWF) format. Timecode support is made possible with a TA5 input for jam sync purposes, and clock accuracy is better than 1 ppm, providing synchronization for all-day shoots.

Dear reader, there are pro-quality solutions and then truly professional devices. We think you’ll know into which camp Lectrosonics falls. If these transmitters excite you, please let us know in the Comments section, below.
