D Squared adds bodypack transmitter

The DBu-LEMO provides RF power selections at 10mW, 25mW and 50mW

The DBu-LEMO bodypack transmitter is the latest addition to the D Squared product series from Lectrosonics. It is fully compatible with the DSQD digital receiver and offers a tuning range between 470MHz and 608MHz – going up to 614MHz for the export version.

Designed with circuitry to extend its operating time from a pair of AA batteries, the DBu-LEMO provides RF power selections at 10mW, 25mW and 50mW, allowing for use in a variety of licensed and unlicensed applications. With an audio frequency response of 20Hz to 20kHz (+0.0/–3dB), a dynamic range of 110dB before limiting and a flat in-band phase response, the beltpack transmitter is also built with a digital architecture to facilitate encryption in high-level security applications.

Lectrosonics states that studio-quality audio is achieved thanks to the components used in the preamp, a wide range input gain adjustment and analogue limiting controlled via DSP. The input gain is adjustable in 1dB increments over a range of 52dB, allowing users to match the input signal level, while maximising the audio dynamic range and signal-to-noise ratio. A two-way IR port facilitates a fast set up and allows for data sharing between units, including encryption key transfer.

A switch on top of the unit can be configured as power on/off, mute or talkback. It can also be bypassed altogether. A micro USB jack, meanwhile, can be used to update the unit’s firmware when out in the field using Wireless Designer software on a Mac or PC. The DBu-LEMO can also respond to remote ‘dweedle tone’ commands from third-party apps such as New Endian’s LectroRM, meaning users can change settings, including frequency, audio level, RF power level and sleep/unsleep, from their smart devices.

The aluminium housing is the same size and shape as the previous generation DBa and DBu units, so users can match their accessories with the DBu-LEMO. The 00 Lemo three-pin connector and input wiring is also identical to that on the SSM micro transmitter, enabling the use of existing lavalier microphone cables and audio adapters.
