Dante M2T Digital IEM Transmitter Instruction Manual

Introduction

The M2T, M2T/E01, M2T/E02, M2T/E06 Digital HalfRack 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, digital RF modulation and two stereo digital channels, the M2T, M2T/E01, M2T/E02, M2T/ E06 provides a truly unique IEM product for demanding, professional applications The M2T, M2T/E01, M2T/E02, M2T/E06 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 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, M2T/E01, M2T/ E02, M2T/E06 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, M2T/E01, M2T/E02, M2T/E06 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 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

**Installing two M2T, M2T/E01, M2T/E02, M2T/E06 Transmitters into a

Single Rack Space**

The M2T, M2T/E01, M2T/E02, M2T/E06 transmitter occupies a half rack space, and comes with hardware to mount two transmitters into a single rack space.

1. Remove the Trim Cap (Part #P1330) from both sides of the front panel on both transmitters.
   

2. Remove the breakaway tabs on both sides of the chassis side panels. Use a flat blade screwdriver to pry the tabs outward and snap them off of the chassis.

3. Insert the flange bracket (Part #27076) into the open slot in the side of the chassis cover panel.
   

4. Insert two (2) cap screws (Part #28885) through the rack handle (Part #27082) holes and install the rack handle onto the flange bracket through the holes in the unit’s front panel. Firmly tighten the cap screws using the hex key (Allen wrench) as shown.
   

5. If antennas will NOT be mounted on the front panel of the transmitters, install the hole cap (Part #35959) by aligning the flat on the cap with the flat on the opening.
   
   NOTE: The retaining nuts on the panel and tie brackets are “tensioning lock nut” types designed to prevent the screws from coming loose due to vibration. You will usually feel resistance as you tighten the screws – this is normal.

6. Install one side of the front tie bracket (Part #25991) into the side panel opening in one of the transmitters. Insert the screws, but do not tighten them completely at this point.
   
   Slide the other transmitter over the tie bracket and insert the screws, but do not tighten them completely until the rear tie bracket is installed.
   

7. Remove the four cap screws from the adjacent rear panels, and then use them to attach the rear tie bracket. Do not tighten the screws completely.
   

8. After front and rear tie brackets are installed, place the transmitters on a flat surface so the that the front panels are even with each other. Hold the transmitters in place and tighten all cap screws on the front and rear brackets.

NOTE: If the supplied rubber feet are installed on under side of M2T, M2T/E01, M2T/E02, M2T/ E06, it will not fit in a rack unless there is an empty space below it.

Wireless Designer Software

Download the Wireless Designer software installer from the web sites under the SUPPORT tab at: http://www.lectrosonics.com/US

Wireless Designer only needs to be installed the first time the software is used. Once the software is installed, updates are available by simply clicking on an item in the Help Menu

NOTE: If Wireless Designer is already installed, you must uninstall it before attempting to install a new copy.

Firmware Update Instructions

Firmware updates are made with a file downloaded from the web site and the DSQD connected via USB. The USB port on the transmitter requires a micro-B male plug on the connecting cable. The other end of the cable would normally be a USB A-Type male connector to fit the most common type of USB jack used on computers.

Refer to Help in Wireless Designer software for the procedure.

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 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 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 damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
