The Duet digital wireless monitor system represents a significant step forward for touring performers and other professionals requiring high definition audio in their ears. With 24 bit digital audio, low latency, Dante inputs and a compact, lightweight, diversity bodypack unit, the Duet system should please even the most demanding users, both on and behind the stage.

The new Duet digital wireless monitor system consists of the M2T dual-stereo half-rack transmitter and M2R diversity belt pack receiver. The Duet covers the UHF frequencies of 470-608 MHz (138 MHz) in a single range, uses digital modulation for transmission, and can accept analog or Dante™ digital inputs. The new system can be considered a “wireless IEM” or a deluxe IFB product, designed and developed with professional touring, installation, theater, filmmaking and broadcast customers in mind.

Both the M2T ½ rack transmitter, and the M2R beltpack receiver units have 2-way IR sync, so scan data from the receiver can be sent to the transmitter and thus onto the Ethernet network for use by Wireless Designer™ software for frequency planning and coordination purposes. Additionally, the system includes a Flex List mode, where a number of names and frequencies can be stored in the receiver. This way, a monitor engineer or production manager can quickly find and listen to any of the talents’ mixes on the stage or in the studio.

The compact nature of the M2T ½-rack transmitter means that up to four dual-channel carriers can be sent from 1RU, resulting in either 4 stereo audio feeds or up to 8 mono audio feeds. The tremendous power and flexibility of this system makes it possible to use the Duet for a variety of professional audio applications

Compatible with Wireless Designer™ Software

The M2T half-rack transmitter houses two independent stereo transmitters allowing for up to four stereo or dual-mono transmissions in a single rack space. The audio inputs can be individually configured to be analog or Dante compatible. The analog input connectors arefull size XLR/TRS combo types for balanced line level analog signals while the input preamp circuits use aspecial balanced amplifier with very high common mode rejection to minimize hum and noise. A Dante™ Ultimo™ interface via dual RJ45 connectors accepts Dante networked audio inputs and can cascade the digital stream to additional units via CAT6 cables. An additional RJ45 jack provides an Ethernet connection for programming and control via Wireless Designer™ software and a USB jack on the front panel allows for firmware updates. The transmitter features a full color, backlit LCD for high visibility in any environment, while the chassis is all-metal and can be racked singly or in pairs using included rack mount hardware.

The M2R bodypack receiver employs advanced antenna diversity switching during digital packet headers for seamless audio. The 24 bit digital audio stream guarantees high resolution sound quality with wide dynamic range, low noise floor, and rock-solid stereo image. The receiver can select from stereo, mono from left channel only, or mono from right channel only, giving the unit flexibility in terms of the application. The headphone jack is fed from a high-quality stereo amplifier with 250 mW available to drive headphones or earphones to sufficient levels for stage performance or other environments with significant background noise. A high-resolution, color LCD allows for a wide range of menu options, including precise limiter settings, using detailed graphics. The M2R runs on two AA batteries for an operating time of over 4 hours with alkaline cells.
