AKG Perception Wireless 45 Sports Set with PT45 Bodypack & C544 L Head-worn Mic

The AKG Perception Wireless Sports system with its comfortable C 544 L and ultra lightweight PT 45 bodypack transmitter ensures maximum user mobility for all hands free applications. The C 544 L headworn microphone comes with four moisture shields protecting the transducer from perspiration while you practice your favorite sport. The C 544 L uses the proven transducer of the C 555 L and is quick and easy to put on and replace.

SR 45 Stationary Receiver:

The SR 45 Stationary Receiver delivers a diversity system, professional XLR and jack outputs, and the SMPS solution. The audio level and squelch threshold are adjustable on the receiver. It is a stationary receiver for use with all transmitters of the Perception wireless system.

The SR 45 operates within a switching bandwidth of up to 30 MHz in the 500 to 560 MHz UHF carrier frequency range and offers up to 8 selectable carrier frequencies.

PT 45 bodypack transmitter:

The PT 45 bodypack transmitter lets you use both dynamic microphones and condenser microphones operating on a supply voltage of approx. 4 V. Naturally you may also connect an electric guitar, electric bass or keytar.

The PT 45 operates within a switching bandwidth of up to 30 MHz in the 500 to 560 MHz UHF carrier frequency range and offers up to 8 selectable carrier frequencies.

C 544 L headset microphone:

The C 544 L is a head-worn miniature condenser microphone with a convenient behind-the-neck headband. Resting securely and comfortably on the head, the C 544 is the ideal microphone for any hands free application including gymnastics instruction, presentations, or onstage performances. The microphone has a cardioid polar pattern and therefore "prefers" sounds arriving from the front (from the user's mouth).

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 will place the microphone in front of the corner of your mouth to minimize pop noise and protect the microphone from contamination. The supplied windscreen makes the microphone even less susceptible to wind and pop noise.

A special moisture shield on the microphone capsule makes it difficult for moisture and makeup to penetrate into the microphone. This barrier prevents the microphone sound entries from being clogged by sweat or makeup which would make the sound dull and reduce the sensitivity of the microphone. Therefore, never remove the moisture shield from the microphone.

The C 544 L is a condenser microphone and therefore needs a power supply.
