The original Lectrosonics Duet system, designed for these same applications, was introduced in 2017. Conventional in-ear wireless monitor systems rely on decades-old technology: FM transmission with multiplexed, companded audio. The M2 System employs unique digital technology to provide ruler-flat frequency response, wide dynamic range with no compression, and maximum channel separation for rock-solid stereo imaging or reliable mono operation with no crosstalk. In addition, the digital audio eliminates a compandor and the associated artifacts. The result is crystal clear sound and extremely low distortion with extremely low latency of 1.6ms. The transmitter and receiver housings are all-metal for maximum durability, and both analog and Dante digital signal sources are supported.
The new M2Ra receiver represents the next generation of receivers in this series, with several key new features, starting with phantom power protection on the headphone jack so that the receiver can be safely used as a camera hop receiver. There's also improved IFB analog compatibility mode for better sound quality, and a beefed-up internal power supply that allows for headphones or earphones with impedances as low as 9 ohms to be used and provides better sound quality overall.
Lectrosonics also introduced an improved, easy-to-navigate menu structure, similar to the Lectrosonics DCR822 and DSQD portable receivers. Decreased overall RF noise floor and less RF gain in the front end, reduce overloads from strong interference sources and out-of-band signals, while increased IP3 and 1dB RF compression points allow for improved handling of high signal levels. D2 and HDM mono digital compatibility modes allow the M2Ra to be used as a very small portable receiver or portable monitor device, with mono digital transmitters from the D Squared product line.
The Lectrosonics M2Ra receiver is built with a black anodized finish for a lower visual profile. Since the M2Ra includes a USB jack for firmware update, users can update their units in the field, using the Lectrosonics Wireless Designer software, to update their units when new features become available.
One of the key features of the Duet system is the Flexlist, allowing users to build a list, by name, of up to 24 feeds. With the Flexlist function, users can browse these feeds on an M2Ra easily and quickly with a minimum of navigation, an important tool for monitor engineers and location sound mixers.
Two versions of the M2Ra receiver are available now for worldwide markets: one covering the A1B1 frequency range (470 to 614 MHz), and one covering the B1C1 frequency range (537-691 MHz). This allows a wide selection of operating frequencies for larger systems, and helps avoid interference, even in crowded RF environments.
Well respected within the film, broadcast, and theatre technical communities since 1971, Lectrosonics wireless microphone systems and audio processing products are manufactured in Rio Rancho, New Mexico. A full range of spare parts and a full line of accessories are available from the company’s online store.
