Premium Microphones The Concert 288m Handheld features two CH88 handheld transmitters with Q8 dynamic mic capsules.

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.
