Highly versatile: the WMS 40 PRO instrumental set. The convenient PT 40 PRO bodypack is the smallest and lightest transmitter in its class.
The new C 444 L head-worn microphone from AKG is rugged, extremely easy to use, and offers outstanding price/performance. Resting securely and comfortably on the head, the C 444 is the ideal microphone for any handsfree application including gymnastics instruction, presentations, or onstage performances.
With its new cheek pads, the C 444 L will stay in place even if you turn your head abruptly and a capsule shock mount reduces handling noise to a minimum. A frequency response rise at 10 kHz and rolloff below 800 Hz ensure optimum audio and intelligibility even in noisy environments. The new moisture shield that prevents perspiration from penetrating into the transducer and other design features provide optimum protection from moisture.
