  • Premium Microphones

    The Concert 288m Handheld features two CH88 handheld transmitters with Q8 dynamic mic capsules. The supercardioid pickup pattern provides maximum gain before feedback and excellent off-axis rejection, while a pneumatic capsule shock mount minimizes handling noise. These handheld microphones bring maximum versatility to any dual-user application and can operate for up to eight hours on two AA batteries.

  • AR299m Top and Rear

    Tabletop Dual-Receiver

    Small and light enough to fit in any pocket, the AR299M tabletop receiver emphasizes versatility and functionality while remaining a fraction of the size of other receivers. The true-diversity antenna design provides 300' of wireless reception, while tone key and auto mute technology eliminate unwanted noise and interference when the transmitter is out of range. The AR299M offers dual balanced XLR outputs for each channel, as well as 1/4" and 1/8" mix outputs for easy connection to mixers and PA systems.

  • Straightforward Setup

    Setup is a breeze with a one-touch scan feature that selects the clearest channel from 100 different channels in your performance space. The dual-channel, frequency-agile Concert 288m Handheld system allows for up to eight systems to operate simultaneously per frequency band (region dependent).
