  • All-In-One

    The Concert 288m all-in-one system includes a CH88 handheld transmitter and a CH88 beltpack transmitter with an LM7 lavalier microphone and an HS5 headset microphone. The handheld microphone features a Q8x supercardioid capsule that minimizes handling noise and provides excellent off-axis noise rejection. The LM7 features a lightweight microphone clip for discreet and easy placement on ties, lapels and other clothing. The HS5 headset microphone provides a comfortable fit for hands-free operation. Each transmitter uses two AA batteries and provides up to eight hours of professional-quality audio.

  • 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

    Set up 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).
