M2Ra Digital IEM Receiver
The M2Ra Digital IEM Receiver is a compact, rugged
body-worn unit providing excellent sound quality for
performers or any professionals needing to monitor
detailed audio wirelessly. The M2Ra employs advanced
antenna diversity switching during digital packet head-
ers for seamless audio. The receiver uses digital modu-
lation and covers a wide range UHF frequencies - A1B1,
or B1C1.
The headphone jack is fed from a high-quality stereo
amplier with 250 mW available to drive even inecient
headphones or earphones to sucient levels for stage
performance or other noisy environments. The receiver
can select from stereo, mono from left or right channels
only, or mono from both channels, giving the unit ex-
ibility in terms of application as an IEM or IFB receiver.
An intuitive interface and high resolution, color LCD on
the unit provide performing artists and audio profession-
als alike with a comfortable and condent user experi-
ence.
The M2Ra also employs 2-way IR sync, so can data
from the receiver can be sent to an M2T transmitter and
thus onto Wireless Designer™ Software. This way, fre-
quency planning and coordination can be done quickly
and condently with on-site RF information.
FlexList™
Additionally, the M2Ra includes a FlexList™ mode,
where up to 24 mixes can be accessed by name. This
feature enables a user to quickly nd and listen to any of
the feeds on a stage or set.
A FlexList mix is a prole made up of the channel name,
frequency, mixer settings and limiter settings. The mix
is easily added to the FlexList via the M2Ra IR port, as
synced from an M2T or DCHT and stored until cleared
by the user. The M2Ra allows the user to scroll through
the mixes, making listening and troubleshooting easy
and ecient.
Smart Tuning (SmartTune™)
A major problem facing wireless users is nding clear
operating frequencies, especially in RF saturated envi-
ronments. SmartTune™ overcomes this problem by au-
tomatically scanning all the frequencies available in the
receiver’s frequency range and tuning the receiver to the
frequency with the lowest RF interference, signicantly
reducing setup time.
NOTE: Some regions have certain frequency
restrictions. Depending on LOCALE selection,
the SmartTune and Scan frequency ranges are:
NA: 470.100 - 607.950 MHz
A1B1:
EU: 470.100 - 614.375 MHz
AU: 520.000 - 614.375 MHz
JA: 470.150 - 614.375 MHz
EU: 537.600 - 691.175 MHz
B1C1: AU: 537.600 - 691.175 MHz
JA: 537.600 - 691.175 MHz
RF Front-End with Tracking Filter
A wide tuning range is helpful in nding clear frequen-
cies for operation, however, it also allows a greater
range of interfering frequencies to enter the receiver.
The UHF frequency band, where almost all wireless mi-
crophone systems operate, is heavily populated by high
power TV transmissions. The TV signals are immensely
more powerful than a wireless microphone or IEM
transmitter signal and will enter the receiver even when
they are on signicantly dierent frequencies than the
wireless system. This powerful energy appears as noise
to the receiver, and has the same eect as the noise
that occurs with extreme operating range of the wire-
less system (noise bursts and dropouts). To alleviate this
interference, front-end lters are needed in the receiver
to suppress RF energy below and above the operating
frequency.
The M2Ra receiver employs a selective frequency,
tracking lter in the front-end section (the rst circuit
stage following the antenna). As the operating frequency
is changed, the lters re-tune into six dierent “zones”
depending on the selected carrier frequency.

Encryption
When transmitting audio, there are situations where
privacy is essential, such as during professional sport-
ing events, in court rooms or private meetings. For
instances where your audio transmission needs to be
kept secure, without sacricing audio quality, Lectro-
sonics implements AES256 encryption in our digital
wireless systems. High entropy encryption keys are rst
created by one of the units in the system. The key is
then synced with another encryption-capable unit, via
the IR port. The audio will be encrypted and can only be
decoded if both the transmitter and receivers have the
matching encryption key. If you are trying to transmit
an audio signal and keys do not match, all that will be
heard is silence. The M2Ra gives the option of Encrypt-
ed (DCHX, D2 or HDM modes) with AES 256-CTR, or
non-encrypted (Duet mode) operation under one rm-
ware version. Four dierent key management policies
are available for dierent applications and workows.
