General Description
The MH Series Headsets and Headphones provide the newest design in headset technology from RTS. With its rugged
modular design, lightweight construction, installation options, and its multi-function use beyond the live studio or theater
venue, the MH Series Headsets are designed with you, the user, in mind. The modular design allows you to interchange
different modules to customize the best headset for your environment. The noise-canceling microphone, combined with the
headphone transducers and ANR (Active Noise Reduction) provides clear and precise communication in noisy environments.
Finally, this headset is not limited to live studio or venue communication. By installing the auxiliary audio input module, you
can connect to an MP3 player, and many other audio devices.
The MH Series Headsets and Headphones provide clear communication for professional applications, including live remote or
studio broadcasting, film, TV, and theater intercom communications.
TERMINOLOGY: In this manual, a Headset refers to a device you wear on your head that allows you to both listen
and speak. A headset always has a microphone. Headphones are an audio only device you wear
on you head that allows you to listen only.

use in your specific environment. All the modules are universal which means they are fully
interchangeable, and giving you more flexibility in your headset needs. The versatility of the
MH Dual-Sided Series is obvious when using the music/audio module. Installing the auxiliary audio
module turns the broadcast headset into an every day, every where headset, allowing for MP3 player
hookup, GPS connection, and many other applications.
Expanded frequency response ensures clear communications and enhanced audio performance. The
adjustable output level allows the user to match the headset to the requirements of the surrounding
environment. Acoustic design and active noise reduction, available with the MH-402/402L, combine to
remove common environmental noises.
The design of the MH Series headset with its headband location in relation to the ear cups delivers more
stability when the headset is being worn. All user contact points, ear cup cushions, temple pads,
headband cushions, and the windscreen are completely replaceable allowing for good hygiene.
