M2T/E01

Introduction

The M2T/E01 Digital Half-Rack Transmitter with analog
and digital Dante™ optional network audio inputs
presents an excellent sounding IEM system with a unique
level of performance in a wireless in-ear monitor system.
With ultra-low latency, 24-bit audio, digital RF modulation
and two stereo digital channels, the M2T/E01 provides
a truly unique IEM product for demanding, professional
applications.
The M2T/E01 boasts 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/E01 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/E01 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.

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
