Lectrosonics M2Ra Digital IEM/IFB Receiver (B1C1: 537 to 691 MHz)

The M2Ra Digital IEM/IFB Receiver from Lectrosonics is designed to provide reliable high-quality wireless monitoring for professional musicians, presenters, and performers in live stage, theater, and broadcast applications. This version of the receiver operates in the B1C1 UHF frequency band, which ranges from 537 to 691 MHz depending on your locale. The M2Ra is compatible with the M2T wireless transmitter and features IFB, D2, and HDM compatibility modes for use with additional Lectrosonics transmitter models.

The receiver employs sophisticated antenna diversity switching to ensure reliable reception without dropouts or interference. It also employs 2-way IR sync, sending data from the receiver to the M2T transmitter and allowing frequency planning and coordination to be done quickly and confidently with on-site RF information via Lectrosonics’ Wireless Designer Software.

The 24-bit digital audio stream delivers high-resolution sound quality with a wide dynamic range, low noise floor, and solid stereo imaging. The 3.5mm headphone jack is fed from a high-quality 250mW stereo amplifier, allowing it to drive a wide variety of headphones, earphones, and in-ear monitors.

Users can select from stereo/mono from the left or right channel, or mono from both channels, allowing the receiver to quickly adapt to different applications. An intuitive mixing interface and high-resolution color LCD provide performing artists and monitor engineers with a comfortable and confident user experience. The M2Ra runs on two AA lithium or high-capacity NiMH rechargeable batteries for up to 7 hours.
