Consumer Alert for US Users - FCC Order DA 10-92
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this micro­phone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless mi crophone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones. To operate wireless microphone systems at power greater than 50mW, you must qualify as a Part 74 user and be licensed. If you qualify and wish to apply for a license go to: http://www.fcc.gov/Forms/Form601/601.html

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 out­of-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.
Digital IEM Transmitter
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 bandwidth 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
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.
