The AMT ACCR is a dual self-contained grill mounted microphone for right-hand side mounting on mid- to large-size accordions. It features two microphones balanced for the accordion, which allows the lower bassoon reeds to stand out from the higher volumes that the clarinet and piccolo reeds can produce. The microphone mounts with either dual lock touch fastener to allow for easy transitions to other accordions, or can mount with the included mounting blocks and screws for a more permanent setup. With either mounting option, the ACCR can be easily removed after use. The ACCR includes the BP45 preamp which runs on either phantom power or one AA battery.
