The D Squared System is built on Lectrosonics' 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 470-608 MHz (470-614 MHz for export versions).
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. Note that the 4-channel DSQD is priced below a Venue 2 loaded with four VRT2s.
The DBu belt pack and DHu handheld transmitters include specially developed, high-efficiency digital circuitry for extended operating time on two AA batteries and offers RF power selections at 25 and 50 mW. The pure digital architecture enables AES 256-CTR encryption for high-level security applications. Studio quality audio is assured by premium components in the preamp, wide-range input gain adjustment and DSP-controlled analog limiting. Input gain is adjustable over a 45 dB range in 1 dB steps to allow an exact match to the input signal level, maximizing the dynamic range and signal to noise ratio. USB ports on the transmitters allow for firmware updates in the field. Two-way IR ports ensure quick setup and allow for encryption key transfer and other data sharing between units.
