Designed for a range of applications including broadcast, film production and live events where high-quality audio and reliability are required, Lectrosonics’ D Squared digital wireless mic system employs the company’s fourth-generation digital architecture, offering improved flexibility, fast setup, studio-quality audio and ultra-low latency.
The D Squared system consists of the DSQD digital receiver, DBu digital beltpack transmitter, and DHu digital handheld transmitter. The system operates across a tuning range from 470 to 608 MHz (470 to 614 MHz for export versions) and features 24-bit, 48kHz digital audio, two-way IR sync, and three levels of encryption.
The DSQD 4-channel receiver occupies a half-rack, yielding eight channels in a single space— the highest rack density of any wireless system. Front-panel features include a high-res color display, headphone jack with level control, IR port, power switch and USB connector.
Rear-panel connections include analog and Dante digital audio outputs, BNC antenna ports with buffered loop outputs for feeding another receiver, and an Ethernet port for communication with Wireless Designer software. A serial port enables connection between receivers for data sharing and frequency coordination. The DSQD is backward-compatible with any Lectrosonics Digital Hybrid Wireless transmitter and provides a choice of three diversity schemes.
Constructed with a housing milled out of aluminum alloy, the DHu handheld transmitter is compatible with Lectrosonics’ HHC cardioid condenser microphone capsule, or may be used with a variety of capsule heads employing the standard 1.25-inch/28-thread pitch mount. A programmable button on the outside of the housing can be user-configured as a push-to-talk, cough, mute or power switch, or may be bypassed.
The DBu beltpack is made from solid machined aluminum and features a removable antenna with SMA connector. Audio input is via TA5 connector with servo-bias for compatibility with a wide range of mic and line-level sources. A multi-function switch on the top panel can be configured as power on/off, mute, talkback, or may be bypassed.
Both transmitters operate using high-efficiency digital circuitry for extended run time using two AA batteries and offer a choice of RF transmitter power (25 or 50 mW). The pure digital architecture enables AES 256-CTR encryption for high-security applications. USB ports on the transmitters facilitate firmware updates in the field as features are added in the future.
