The Lectrosonics M2Ra bodypack receiver employs advanced antenna diversity switching during digital packet headers for seamless audio. The digital audio stream guarantees high resolution sound quality with wide dynamic range, low noise floor, and rock-solid stereo image. The receiver can select from stereo, mono from left channel only, or mono from right channel only, giving the unit flexibility in terms of the application. The headphone jack is fed from a high-quality stereo amplifier with 250 mW available to drive headphones or earphones to sufficient levels for stage performance or other environments with significant background noise. A high-resolution, color LCD allows for a wide range of menu options, including precise limiter settings, using detailed graphics. The M2Ra runs on two AA lithium or rechargeable batteries. Improvements over the original M2R include better RF performance, P48 protection on the headphone output, reorganized menu structure, and a black anodized finish for a lower visual profile.
