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
