Lectrosonics M2R Overview

The M2R Digital IEM/IFB Receiver from Lectrosonics is a wireless receiver that employs antenna diversity and covers the UHF frequencies of 470.1 to 607.975 MHz. The receiver's headphone jack is fed from a high-quality stereo amplifier and can be used when paired with an M2T wireless transmitter (sold separately) for driving headphones or earphones in live stage, theater, and performance applications.

The receiver can select from stereo, mono from left channel only, or mono from right channel only, giving the unit flexibility depending on its intended application. An intuitive mixing interface and high-resolution, color LCD on the beltpack receiver provide performing artists and monitor engineers with a comfortable and confident user experience.

Furthermore, the receiver's built-in, antenna-diversity switching provides seamless audio during operation, and the 24-bit digital audio stream delivers high-resolution sound quality with a wide dynamic range, a low-noise floor, and solid stereo imaging. In addition, the M2R runs on two AA batteries for an operating time of over 4 hours (with alkaline batteries) and 7 hours (with lithium batteries).

Can a Lectrosonics M2R be used with an IFBT4?

Can a Lectrosonics M2R be used with an IFBT4?
Asked by: Robert
So long as the M2R is set to IFB mode, and the IFBT4 is not in a frequency range above 608mhz, yes these two could work together.

is it possible to connect two m2r to a single dcht to achieve, two m2rs' getting the same stereo feed from one dcht?
Asked by: Jonathan
I'm afraid not. The Lectrosonics M2R Digital IEM/IFB is intended to be used as a receiver for an IFB or monitor system. It is intended to be paired with a Lectrosonics M2T IEM transmitter. BH #LEM2T like this one on the B&amp;H website.

Which transmitters would work with the flexlist feature?
Asked by: Matthew
The Lectrosonics M2T transmitter is compatible with the M2R receiver. The M2R Receiver includes a FlexList mode on which up to 16 mixes can be accessed by name. This feature enables a monitor engineer to quickly find and listen to any of the performer&rsquo;s mixes on the stage. A FlexList mix is a profile of a performer&rsquo;s personal transmitter. The mix includes the name the user chooses for that unit, frequency, mixer settings and limiter settings. The mix is easily shared via the M2R IR port, added to the list of 16 mixes and stored until cleared by the user. The M2R allows the user to toggle between the mixes, making troubleshooting issues easy and efficient.

Is there a quick way for selecting another frequency? Example, lav 1 is channel 512.00, lav 2 is channel 546.400. Grabbing signal from two ifb mode transmitters... I know the other ifbs do this where users can click one button to switch between channels.
Asked by: Matthew
If you don't use encryption, you can use FlexList. If you load the firmware to enable encryption, flexlist is not an option. I use the M2R-X firmware with encryption with the M2T, so what I've done is transmit on two frequencies with the same millihertz but different megahertz. For example, I transit on 520.500 MHz and 518.500 MHz. Then, I can quickly change the frequency in the menu and only toggle the MHZ (520 - 518). With some experience you can switch frequencies in a matter of seconds with the M2R-X firmware.
