M2R-X
M2R Digital IEM Receiver
The M2R Digital IEM Receiver is a compact, rugged
body-worn unit providing studio-grade sound quality
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 receiver uses digital
modulation and covers UHF frequencies from 470.100
to 614.375 MHz.
NOTE: Some regions have certain frequency restrictions.
Depending on LOCALE selection, the SmartTune and Scan
frequency ranges are:
NA: 470.100 - 614.375 MHz
EU: 470.100 - 614.375 MHz
AU: 520.000 - 614.375 MHz
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 interface and high resolution,
color LCD on the unit provide performing artists and
audio professionals alike with a comfortable and confident user experience.
The M2R also employs 2-way IR sync, so can data
from the receiver can be sent to a transmitter and
thus onto Wireless Designer™ Software, via USB or
Ethernet. This way, frequency planning and coordination can be done quickly and confidently with on-site
RF information.
Encryption
The special firmware version M2R-X provides AES
256 bit encryption. When transmitting audio, there are
situations where privacy is essential, such as during
professional sporting events, in court rooms or private
meetings. Truly entropic encryption keys are first created by the M2T-X Transmitter. The key is then synced
with the M2R-X via the IR port. The audio will be encrypted and can only be decoded and heard if both the
transmitter and the receiver have a the matching key.
RF Front-End with Tracking Filter
A wide tuning range is helpful in finding clear frequencies 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 immensely 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 appears 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,
tracking 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
470 MHz
BLOCK
BLOCK
In the front-end circuitry, a tuned filter is followed by
an amplifier and then another filter to provide the selectivity needed to suppress interference, yet provide a
wide tuning range and retain the sensitivity needed for
extended operating range.
BLOCK
BLOCK
BLOCK
614 MHz
NOTE: Unencrypted firmware versions of the
Duet system will not interact with encrypted
sysem components. Components in a system
must either have all 2.x (unencrypted) firmware
installed, or have all 3.x (encrypted) firmware
installed in order to interoperate.
Smart Tuning (SmartTune™)
A major problem facing wireless users is finding clear
operating frequencies, especially in RF saturated environments. SmartTune™ overcomes this problem by
automatically scanning all the frequencies available in
the receiver’s frequency block and tuning the receiver
to the frequency with the lowest RF interference, significantly reducing setup time.

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.

System Setup Procedure
Step 1) Install Batteries
Install the batteries according to the diagram marked
on the back of the housing. The battery door makes a
connection between the two batteries. It is suggested
that you use lithium or high capacity NiMH rechargeable batteries.
Step 2) Turn the power on
Power on the M2R with the On/Off/Volume knob and
select the battery type in the menu. Check the BATT
LED on the control panel to verify adequate power is
present. The LED will glow green with good batteries.
Step 3) Locate and Set a Clear Frequency
A clear frequency can be located and set using the
SmartTune function, or with manual scanning of the
spectrum and selecting a frequency.
Using SmartTune
• SmartTune will scan the entire tuning range of the
receiver and automatically find a clear frequency
for operation. Navigate to SmartTune in the menu
and press MENU/SEL. The receiver will scan the
spectrum and display and set a clear frequency.
• The clear frequency will then need to be transferred to or set on the associated transmitter (see
Step 4).
Manual Scanning
• Navigate to Scan in the LCD menu and press
MENU/SEL. The scanning will continue across the
spectrum and then wrap back and start over. Allow
the scan to complete at least once. If you let the
scanning continue to wrap and repeat, the scanning results will accumulate and may identify RF
signals that are intermittent and might be missed
with a single scan.
• Press MENU/SELECT to pause the scan. Use the
UP and DOWN arrows to roughly tune the receiver
by moving the cursor to an open frequency.
• Press MENU/SELECT again to zoom in for fine
tuning and use the UP and DOWN arrows to scroll
across the spectrum to a place with little or no RF
activity (open frequency). When an open frequency
has been selected, press the BACK button for the
option to keep your newly selected frequency or to
revert to the previous frequency.
Step 4) Choose an Encryption Key
Choose an encrytpion key type to match transmitter.
Step 5) Sync with a Transmitter
In the transmitter, use “GET FREQ” or “GET ALL” in
the menu to transfer frequency or other information via
the IR ports. Hold the M2R receiver IR port close to
the front panel IR port on the transmitter and press GO
on the transmitter.
Step 6) Enable RF in the Transmitter
In the transmitter menu, enable RF and select
appropriate RF power level. The blue “link” LED on the
top of the receiver should light up, indicating a valid
RF link.
Step 7) Send Audio
Send an audio signal to the transmitter and the receiver audio meters should respond. Plug in headphones
or earphones. (Be sure to start with the receiver volume knob at minimum!)
WARNING: If connecting this receiver to
microphone inputs, such as in a camera hop
arrangement, 48V phantom power MUStTbe
turned off. Otherwise, damage to the receiver
will occur.
If using a mono earphone with this unit, you
must select “Mono” under “Earphone Type”
in the menu. Otherwise, the unit will use
batteries very quickly and get hot.

Encryption Key Management
The M2R-X Version has four options for encryption
keys:
• Volatile: This one-time only key is the highest
level of encryption security. The Volatile Key exists
only as long as the power in both the M2R-X Receiver and the M2T-X Transmitter remains on during a single session. If the M2R-X is powered off,
but the M2T-X Transmitter has remained turned on,
the Volatile Key must be sent to the receiver again.
If the power is turned off on the M2T-X Transmitter,
the entire session concludes and a new Volatile
Key must be genereated by the transmitter and
sent to the M2R-X via the IR port.
• Standard: Standard Keys are unique to the M2T-X
Transmitter. The M2T-X generates the Standard
Key. The M2R-X Receiver is the sole source of the
Standard Key, and because of this, the M2T-X may
not receive (get) any Standard Keys.
• Shared: There are an unlimited number of
shared keys available. Once generated by the
M2T-X Transmitter and transferred to the M2RX, the encryption key is available to be shared
(synced) by the M2R-X with other encryption capable transmitters/receivers via the IR port. When
the M2R-X is set to this key type, a menu item
named SEND KEY is available to transfer the key
to another device.
• Universal: This is the most convenient encryption option available. All encryption-capable
Lectrosonics transmitters and receivers contain
the Universal Key. The key does not have to be
generated by the M2T-X. Simply set a Lectrosonics
encryption-capable transmitter and the M2R-X Receiver to Universal, and the encryption is in place.
This allows for convenient encryption amongst
multiple transmitters and receivers, but not as
secure as creating a unique key.
NOTE: When the M2R-X is set to Universal
Encryption Key, Wipe Key and Share Key will not
appear in the menu.

If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop
attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units.
Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it
does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by
phone for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by e-mail or by phone. We need
to know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help
speed your repair through our receiving and repair departments. The return authorization number must be
clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with
the proper packing materials. UPS or FEDEX is usually the best way to ship the units. Heavy units should be
“double-boxed” for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
