Rio Rancho, NM (May 8, 2020) — Lectrosonics has launched its new DPR digital plug-on transmitter and the DSQD/AES-3 receiver for location sound recording, intended for use on a variety of applications including boom miking. Both products are part of the D Squared wireless family platform.
The DPR digital plug-on transmitter is fully compatible with the DSQD digital receiver and features a tuning range of 470 to 608 MHz (470 to 614 MHz for the export version). The new transmitter includes specially developed circuitry for extended operating time on two AA batteries, and offers RF power selections at 25 and 50 mW. AES 256-CTR encryption is provided for high level security applications, and the unit sports phantom power, selectable to off, 5v, 15v or 48v to accommodate a range of microphone types.
The DPR features DSP-controlled analog limiting, and input gain is adjustable over a 55 dB range in 1 dB steps to allow an exact match to the input signal level, maximizing audio dynamic range and signal to noise ratio.
The DPR can be configured as either a transmitter or a recorder, with files stored on microSD card memory in the Broadcast Wave .wav (BWF) format at 24 bits, 48 kHz sample rate. A 3.5mm TRS jack on the side of the unit allows jam sync with timecode, and Lectrosonics says the unit’s timecode accuracy is better than 1PPM due to the temperature compensated crystal (TCXO) clock. The DPR also responds to remote “dweedle tone” commands, available via third-party apps such as New Endian’s LectroRM and PDRRemote, allowing users to change settings including frequency, audio level, lock/unlock, and also to start and stop recordings.
The machined aluminum DPR housing is the same size and shape as the previous generation plug-on units including the HM and HMa so that standard accessories are compatible with the new unit, including the PHTRAN3 pouch and the HMCVR silicone cover. The input wiring is also the same as previous generations, allowing the use of existing cable and barrel adapter accessories including the MCA5X and MCA-M30.
The DPR features an audio frequency response of 25 Hz to 20 kHz +0.0, – 3dB, a dynamic range of 110 dB before limiting and a flat in-band phase response, allowing it to be used as a wireless test and measurement link with calibrated microphones, for audio system alignment and monitoring.
The new DSQD/AES3 digital receiver is a four-channel, half-rack design with high-resolution color display, analog or AES digital outputs, and rear BNC antenna ports with “loop-thru” buffered BNC outputs to another receiver. The new receiver is compatible with the latest Lectrosonics all-digital transmitters. The DSQD/AES3 is also backward compatible with any Digital Hybrid Wireless transmitters. Three different receiver diversity schemes can be employed depending on the needs of the application, including switched (during packet headers for seamless audio), Digital Ratio Diversity, or Digital Frequency Diversity. The DSQD/AES3 includes digital talkback capability when used with any talkback-enabled transmitter.
A headphone jack is included on the DSQD/AES3 for audio monitoring per channel. Ethernet and USB ports allow the receiver to connect to Lectrosonics Wireless Designer software for programming and monitoring. Antenna bias power can be engaged in the menu, and front panel LEDs show the status. Each DSQD/AES3 ships with half the rack hardware needed to mount two units together, yielding 8 channels in 1RU.
The Lectrosonics DPR Digital Plug-on Transmitter and the DSQD/AES-3 Receiver will be available in Q3, 2020.
