• Features

• PT 40 PRO
  
• Miniature transmitter
  
• Single-battery powering
  
• Multichannel capability for simultaneous use of up to seven channels (maximum number of channel depends on local frequency plans).
  
• High Definition Audio Performance technology ensures the legendary, realistic AKG sound and perfect audio transmission.
  
• Transmitter operates for at least 30 hours off a single AA size battery, saving cost, maximizing dependability, and minimizing onstage stress.
  
• C 444 headset mic
  
• Ergonomically optimized behind-the-neck headband
  
• Moisture shield
  
• External shock mount for high mechanical-noise rejection
  
• The new C 444 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 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.
