Digital IEM Receiver
M2R
TECHNICAL DATA
Digital IEM Receiver
• IEM (Wireless Monitor) receiver
with digital RF
• 24-bit digital audio
• IR (infrared) port for fast setup
• High resolution, color LCD
• Stereo or mono operation
• Low latency of 1.4 ms with
analog inputs
M2R Overview
The M2R Digital IEM Receiver employs advanced
antenna diversity switching during digital packet
headers for seamless audio. The receiver covers the
UHF frequencies of 470-608 MHz in a single range and
uses digital modulation. The 24-bit digital audio stream
guarantees high resolution sound quality with wide
dynamic range, low noise floor, and solid stereo image.
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 noisy environments. 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. An intuitive mixing interface and high
resolution, color LCD on the belt pack receiver provide
performing artists and monitor engineers alike with a
comfortable and confident user experience.

M2R
The receiver employs 2-way IR sync, so scan data from
the receiver can be sent to a transmitter and thus onto
the Ethernet network for use by Wireless Designer™
software for frequency planning and coordination purposes. Additionally, the M2R includes a FlexList™ mode,
where a number of names and associated frequencies
can be stored. This feature benefits a monitor engineer
by enabling quick finding and listening to any of the performers’ mixes on the stage. A high density, backlit, color
LCD allows for a wide range of menu options, including
precise limiter settings, using detailed graphics.
M2R Summary
The M2R operates in the UHF frequencies of 470-608
MHz in a single range, using digital modulation for transmission.
Housings and panels are machined aluminum with Ebni
finishes with laser etched marking for durability, yet it is
lightweight and sleek in order to be comfortable on the
artist’s body. The M2R features a user-friendly interface
with a high-resolution, backlit, color LCD and membrane
switches. The M2R runs for 7 hours on two lithium AA
batteries.
