| The AKG WMS 45 Sport A 1 Perception Wireless Sports Set is a lightweight, headworn wireless microphone system that allows for maximum user mobility during sports class instruction and all other hands-free applications.
The system includes the SR 45 wireless receiver, PT 45 bodypack transmitter and the C 544 L headworn microphone.
The C 544 L is a headworn miniature condenser microphone with a cardioid polar pattern and convenient behind-the-neck headband. The microphone body containing the condenser transducer is shock mounted on the microphone arm in order to suppress cable and mechanical noise. The microphone arm places the mic in front of the corner of your mouth, rather than directly in front of your mouth. This is to minimize pop noise and protect the microphone from contamination. Furthermore, a moisture shield on the microphone capsule is designed to make it difficult for sweat and makeup to penetrate into the microphone.
To help you find an interference-free channel to use, the Perception Wireless Sports Set has 8 UHF frequencies to choose from. Designed for long-lasting continuous use, the compact PT 45 bodypack is powered with a single AA battery for up to 8 hours. The SR 45 receiver provides XLR and 1/4" jack outputs for connection to your mixer and amplification system.
Features:
- 8 hours of operation with a single AA size battery
- PT 45 bodypack transmitter also compatible with all AKG MicroMics
- Low battery indicator
- PT 45 bodypack designed to be compact and lightweight
- C 544 L headworn microphone comes with moisture shields protecting the transducer from perspiration for sports instruction and other active applications. The C 544 L uses the transducer of the C 555 L and is designed to be quick and easy to put on or replace if necessary

Shure WBH54T Tan Headworn Condenser Microphone
WBH54B is a subminiature, electret condenser head worn microphone. It provides uncompromised
sound quality and reliability with minimal visibility in applications such as broadcast, theater, and touring.
Despite their small size, the condenser element delivers full, clear, and natural reproduction of speech
and vocals. The microphone features a durable, low-profile wire frame headband which is fully adjustable for
stability and comfort. A plastic carrying case protects the microphone and its accessories.
Features:
Supercardioid polar pattern provides maximum gain-before-feedback and ambient rejection
Extended frequency response tailored for vocal performances
Able to handle extremely high sound pressure levels (SPL)
Snap-fit foam windscreens stay in place during intensive movement
Available with an in-line preamp or with a TA4F connector for wireless applications
Black finish

| Shure WH20TQG Dynamic Headset Microphone Shure Performance MicrophonesDynamic Headset Microphone
The improved version of the WH10, the Shure Model WH20TQG is a rugged, light-weight, dynamic headset microphone that provides high-quality voice pickup. It fits securely for active microphone users, such as aerobics instructors and musicians, with low visibility for stage appearances. The WH20 is suitable for any voice communications application where comfort and reliability are required.
The WH20 TQG has a cardioid (unidirectional) pickup pattern. This provides greater gain-before-feedback and isolation from ambient noise and other unwanted sound sources, such as air-conditioning, musical instruments and loudspeakers. A carefully shaped frequency response includes a voice-frequency presence peak and a low-frequency rolloff to compensate for the proximity effect inherent in cardioid microphones during close-talk operation.
An integrated elastic CROAKIES ? headband secures the headset comfortably. The headband, wireframe, and gooseneck are adjustable to accommodate any head size or shape. The WH20 TQG is supplied with a foam windscreen and clothing clip.
Features:
- Lightweight wireframe and headband adjust for a secure, comfortable fit
- Extra-strong, small-diameter attached microphone cable resists breakage
- Collapsible microphone boom for easy storage and transportation
- Smooth, natural frequency response comparable to high-quality dynamic hand-held vocal microphones
- High input clipping level eliminates overload distortion
- Reliable at temperature and humidity extremes
- Supplied foam windscreen and clothing clip
- The WH20TQG has a miniature four-pin female Tini "QG" connector for direct connection to Shure wireless body pack transmitters - This microphone to be used ONLY with an existing Shure body-pack transmitter.
