The 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.Main Features:IEM (Wireless Monitor) receiver with digital RFIR (infrared) port for fast setupHigh resolution, color LCDStereo or mono operationLow latency of 1.6 ms with analog inputsP48 Phantom power protection on headphone outputAnalog IFB compatibility mode availableAES256 Encrypted or non-encrypted operationFlexlist for recalling IFB or IEM feeds by nameSpecifications:Modulation Type: 8PSK with Forward Error CorrectionEncryption Type: AES-256 in CTR modeLatency: (overall system)Digital Source: 1.0 ms plus Dante networkAnalog Source: <1.6 msAudio Performance:Frequency Response: 10 Hz - 12 KHz, +0, -3dBTHD+N: 0.15% (1kHz @ -10 dBFS)Dynamic Range: >95 dB weightedAdjacent Channel Isolation >85dBDiversity Type: Switched antenna phase, during packet headersAudio Output: 3.5 mm stereo jackPower requirements: 2 x AA batteries (3.0V)Battery life: 7 hours; (2) Lithium AAPower consumption: 1 WDimensions:Height: 3.0 in. / 120 mm.
