The AKG C 516 ML is a lightweight cardioid mini microphone for use on accordions, guitar speakers, piano and keyboard/organ cabinets. The included screws and double-sided, solvent-free adhesive pads make it easy to install the microphone on your musical instrument or amp exactly where you need it. Using two C 516 MLs (one on the bass and one on the treble side) and an optional B 29 L battery power supply is an ideal way to mic up an accordion. The C 516 ML is the only version available and can be used with the B 29 L battery power supply, AKG WMS Series bodypack transmitters, or the MPA V L adapter for external phantom powering. The unique adapter plate A 400 allows easy attachment of the AKG pocket transmitters.
