Digital IEM Transmitter
Rio Rancho, NM 3
Introduction
The M2T Digital Half-Rack Transmitter with analog and
optional digital Dante™ network audio inputs presents
an excellent sounding IEM system with a unique level of
performance in a wireless in-ear monitor platform. With
ultra-low latency, 24-bit audio, digital RF modulation
and two stereo digital channels, the M2T provides a
truly unique IEM product for demanding, professional
applications.
The M2T includes a USB port for firmware updates and
an IR port for fast setup. A large, high resolution, backlit
LCD and large membrane switches provide an intuitive
interface that is highly visible in daylight or dimly lit
conditions.
The half-rack transmitter provides four audio inputs which
can be individually configured to be analog or Dante
compatible. The input connectors are full size XLR/TRS
combo types for balanced line level analog signals. Input
preamp 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 modulated RF signal
is filtered before and after amplification to suppress out-
of-band noise and spurious signals.
Conventional in-ear wireless monitor systems rely
on decades-old technology: FM transmission with
multiplexed, companded audio. The M2T Transmitter
employs unique technology to provide ruler-flat frequency
response from 20 Hz to 15 kHz and maximum channel
separation. 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%.
The M2T is designed and developed with the professional
touring, installation, theater and broadcast customers in
mind. The transmitter chassis is all-metal. The front panel
is an aluminum extrusion with a durable powder coat
finish.
Firmware updates are made via the USB port on the
front panel of the housing. The procedure is very simple
using a standard micro USB cable connected to a PC.
Setup and adjustment are enabled through a backlit LCD,
membrane switches and an intuitive menu structure.
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 ana-
log AV installations.
With Dante, existing infrastructure can be used for high
performance audio as well as for ordinary control, moni-
toring or business data traffic. Digital networks utilize
standard IP over Ethernet offering high bandwidth ca-
pable 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

Service and Repair
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 and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop at-
tempt 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 email 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 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.
