The DSQD receiver is also backward compatible with any Digital Hybrid Wireless® transmitters including the SM Series, LT, HM Series, SSM, HH Series, UM400, UM400a, LM Series, MM Series, and WM. Three different receiver diversity schemes can be employed depending on the needs of the application, including antenna switching (during packet headers for seamless audio), Digital Ratio Diversity, or Digital Frequency Diversity (for full redundancy with two transmitters). Continuously tunable tracking filters ensure excellent RF performance even in difficult environments. The DSQD includes talkback capability when used with any talkback-enabled transmitter. Antenna bias power can be engaged in the menu and front panel LEDs show the status. Analog XLR and Dante™ outputs are provided. Each DSQD ships with half the rack hardware needed to mount two units together, yielding 8 channels in 1RU.The D Squared System is built on our 4th-generation digital architecture for excellent flexibility, ultra-fast setup, studio quality audio, and ultra-low latency. Features include 24 bit, 48 kHz digital audio, 2-way IR sync, three encryption modes, three receiver diversity choices, and a tuning range from 470-614 MHz.
