Product Overview
The DBSM and DBSMD digital transcorders are specifically designed for the film industry, offering time code jam sync capability. They provide hands-free setup, adjustable input gain, selectable low-frequency roll-off, and various output power levels. With water-resistant control panels, OLED displays, and compatibility with AA batteries, they are versatile and compatible with accessories from SMWB and SMDWB transmitters.
