Lectrosonics M2 Duet

A digital wireless monitoring (IEM) system consisting of the M2T dual-stereo half-rack transmitter and M2R beltpack receiver. Duet covers the UHF frequencies of 470 – 608 MHz in a single range, uses digital modulation for transmission, and can accept analog or Dante digital inputs. The M2T houses two independent stereo transmitters, allowing for up to four stereo or dual-mono transmissions. The analog input connectors are XLR/TRS combo types for balanced line level signals while the input preamp circuits use a balanced amplifier with high common mode rejection to minimize hum and noise. A Dante Ultimo interface via dual RJ45 connectors accepts Dante networked inputs and can cascade to additional units via Cat-6 cables. An additional RJ45 jack provides an Ethernet connection for programming and control with Wireless Designer software. Both the M2R and M2T 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 for frequency planning and coordination purposes. The system also includes a FlexList mode, where a number of names and associated frequencies can be stored in the receiver. The M2R runs on two AA batteries for an operating time of more than four hours with alkaline cells.
