The Duet digital wireless monitor system is a new IEM solution from Lectrosonics that incorporates Dante digital inputs in addition to being able to accept analogue feeds. It comprises the M2T dual-stereo half-rack transmitter and M2R diversity beltpack receiver. Designed with touring, installation, theatre, filmmaking and broadcast applications in mind, it covers a UHF frequency range between 470MHz and 608MHz using digital modulation for transmission.
The M2T transmitter allows for up to four stereo or dual-mono transmissions and enables audio inputs to be individually configured as either analogue or Dante. Analogue inputs are all XLR/TRS ports, whereas Dante networked audio inputs are received via dual RJ45 connectors that facilitate a Dante Ultimo interface. A further RJ45 port provides an Ethernet connection for programming and control using Wireless Designer software, while a USB dock on the front panel if for firmware updates.
Meanwhile, the M2R receiver runs on a pair of AA batteries for a reported operating time of more than four hours when employing alkaline cells. It has been developed to offer seamless audio by making use of antenna diversity switching during digital packet headers. The headphone jack receives its feed from a 250mW stereo amplifier that is designed to drive sufficient levels for use in noisy environments.
Both the M2R and M2T boast 2-way IR sync, meaning that scan data from the receiver is distributed to the transmitter and on to the Ethernet network. From there, Wireless Designer can be used for frequency planning and coordination.
