System Setup Procedures
Summary of Steps
1) Install receiver batteries and connect power to
transmitter.
2) Power receiver on with On/Off and Volume knob.
3) Scan for an available frequency on the receiver.
4) Power on the transmitter and sync with receiver.
5) Enable RF in transmitter.
6) Send audio.
1 and 2) Install Receiver Batteries & Connect
Transmitter Power
Connect power to the M2T transmitter (page 16).
Install the receiver batteries (lithium recommended,
page 8) according to the diagram marked on the back
of the housing. Power on the M2R and select the bat-
tery type in the menu (page 13). Check the BATT LED
on the control panel to verify adequate power is pres-
ent - the LED should glow green (page 6).
3) Scan For An Available Frequency
Navigate to Scan in the LCD menu (page 11). The
first scan should be allowed to run completely. Once a
full cycle has been completed, press MENU/SELECT
again to pause the scan. Use the UP and DOWN ar-
rows to roughly tune the receiver by moving the cursor
to an open spot. Press MENU/SELECT to zoom in for
fine tuning. When an open frequency has been select-
ed, press the BACK button for the option to keep your
newly selected frequency or to revert to where it was
set before the scan (page 11).
4) Sync With A Transmitter
Use transmitter “get settings” menu to transfer fre-
quency or other information from the receiver to the
transmitter (page 19).
5) Enable RF in Transmitter
From the transmitter menu, enable RF and select ap-
propriate RF power level (page 19). The blue “link” LED
on the top of the receiver should light up, indicating an
RF link.
6) Send Audio
Send an audio signal to the transmitter and adjust
the send level from your mixer until the audio meters
on the transmitter show good level. The peaks should
be close to the top of the scale (but not over) and the
average should be above the -20 mark. The receiver
audio meters should also respond to the audio. Plug in
headphones or earphones. (Be sure to start with the
receiver volume knob at minimum!)

Duet System Overview
The M2 Duet digital IEM system is designed and
developed with the professional touring, installation,
theater and broadcast customers in mind. Convention-
al in-ear wireless monitor systems rely on decades-old
technology: FM transmission with multiplexed, com-
panded audio. The M2 System employs unique digital
technology to provide ruler-flat frequency response
from 20 Hz to 15 kHz, wide dynamic range with no
compression, and maximum channel separation for
rock-solid stereo imaging or reliable mono opera-
tion with no crosstalk. In addition, the digital audio
eliminates a compandor and the associated artifacts.
The result is crystal clear sound and extremely low
distortion of <0.15% with extremely low latency. The
transmitter and receiver housings are all-metal for
maximum durability.
The system tunes across six standard frequency
blocks, or from UHF frequencies from 470.100 to
607.000 MHz (up to 614.375 for the EU version). This
allows a wide selection of operating frequencies for
larger systems, and helps avoid interference, even in
crowded RF environments.
The M2T Digital Half-Rack Transmitter can accept up
to four analog or digital Dante™ (optional) network
audio inputs to deliver two stereo or four mono audio
feeds over two independent RF carriers. A 2-way IR
port enables quick, trouble-free setup while a large,
high resolution, backlit LCD and large membrane
switches provide an intuitive interface that is highly vis-
ible in daylight or dimly lit conditions.
The input connectors are full size XLR/TRS combo
types for balanced line level analog signals. Input pre-
amp circuits use a special balanced amplifier with very
high common mode rejection to minimize hum and
noise. Analog signals are converted to an internal 24-
bit digital format which is then encoded, organized into
packets, and passed to an RF modulator. The modu-
lated RF signal is filtered before and after amplification
to suppress out-of-band noise and spurious signals.
The M2R Digital IEM Receiver is a compact, rugged
body-worn unit providing studio-grade sound qual-
ity for performers or any professionals needing to
monitor detailed audio wirelessly. The M2R employs
advanced antenna diversity switching during digital
packet headers for seamless audio. The headphone
jack is fed from a high-quality stereo amplifier with 250
mW available to drive even inefficient headphones or
earphones to sufficient 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 flexibility in terms of
application as an IEM or IFB receiver. An intuitive inter-
face and high resolution, color LCD on the unit provide
performing artists and audio professionals alike with a
comfortable and confident user experience.
What is Dante?
Audinate’s patent pending Dante™ technology is a
flexible Internet Protocol (IP) and Ethernet based
digital AV network technology that eliminates the many
bulky cables needed to provide point-to-point wiring for
analog AV installations.
With Dante, existing infrastructure can be used for
high performance audio as well as for ordinary control,
monitoring or business data traffic. Digital networks
utilize standard IP over Ethernet offering high band-
width capable of transporting hundreds of high quality
channels over Gigabit Ethernet.
Set-up and configuring the system is made easy as
well, saving enormous installation costs and long term
cost of ownership on a digital network. The physical
connecting point is irrelevant: audio signals can be
made available anywhere and everywhere. Patching
and routing now become logical functions configured
in software, not via physical wired links
Summary of Dante Benefits
• Plug-and-play technology – automatic discovery
and simple signal routing
• Reduced Cost & Complexity- No special skills
required to set up audio networking
• Sample accurate playback synchronization
• Add/remove/rearrange components at will
• Deterministic latency throughout the network
• Support mixed bit depths and mixed sample
rates over one network
• Scalable, flexible network topology supporting a
large number of senders and receivers
• Supports 1Gbps networks
• Supports a single integrated network for audio,
video, control, monitoring
• Uses inexpensive, off-the-shelf computer
networking equipment

FlexList™
Additionally, the M2R includes a FlexList™ mode,
where up to 16 mixes can be accessed by name. This
feature enables a monitor engineer to quickly find and
listen to any of the performer’s mixes on the stage.
A FlexList mix is a profile of a performer’s personal
transmitter. The mix includes the performer’s name
(or whatever name the user chooses for that unit),
frequency, mixer settings and limiter settings. The mix
is easily shared via the M2R IR port, added to the list
of 16 mixes and stored until cleared by the user. The
M2R allows the user to toggle between the mixes,
making troubleshooting issues easy and efficient.
RF Front-End with Tracking Filter
A wide tuning range is helpful in finding 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
microphone systems operate, is heavily populated by
high power TV transmissions. The TV signals are im-
mensely more powerful than a wireless microphone or
IEM transmitter signal and will enter the receiver even
when they are on significantly different frequencies
than the wireless system. This powerful energy ap-
pears as noise to the receiver, and has the same effect
as the noise that occurs with extreme operating range
of the wireless system (noise bursts and dropouts). To
alleviate this interference, front-end filters are needed
in the receiver to suppress RF energy below and
above the operating frequency.
The M2R receiver employs a selective frequency track-
ing filter in the front-end section (the first circuit stage
following the antenna). As the operating frequency is
changed, the filters re-tune into six different “zones”
depending on the selected carrier frequency.
BLOCK BLOCK BLOCK BLOCK BLOCK BLOCK
470 MHz 614 MHz
In the front-end circuitry, a tuned filter is followed by an
amplifier and then another filter to provide the selec-
tivity needed to suppress interference, yet provide a
wide tuning range and retain the sensitivity needed for
extended operating range.

Battery Status LED
When the battery status LED on the keypad glows
green the batteries are good. The color changes to red
at a midpoint during the runtime. When the LED begins
to blink red, only a few minutes remain.
The exact point at which the LED turns red will vary
with battery brand and condition, temperature and
power consumption. The LED is intended to simply
catch your attention, not to be an exact indicator of
remaining time.
A weak battery will sometimes cause the LED to glow
green immediately after the transmitter is turned on,
but it will soon discharge to the point where the LED
will turn red or the unit will turn off completely.
RF Link LED
When a valid RF signal from a transmitter is received,
this LED will light up blue.
On/Off and Volume Knob
Turns unit on or off and controls headphone audio
level.
IR (infrared) Port
Settings, including frequency, name, limiter, mix mode,
etc. can be transferred between transmitter and re-
ceiver. FlexList profiles can be gathered by the receiv-
er. Frequency scan information can be sent from the
receiver to the transmitter and on to Wireless Designer
software for coordination purposes.
