The PT 450 is a high-performance, compact bodypack transmitter for a host of applications. Many innovative features enhance both system reliability and user friendliness.

An LC display indicates all important system data at a glance, including the selected frequency in MHz or as a Preset subchannel, available battery capacity in hours, a warning when battery capacity is low, as well as the current transmission mode.

Once you have set a frequency on the receiver, an infrared transmission link will feed the related data to the assigned transmitter within seconds, making the setting up of large multichannel systems child’s play.

The PT 450 uses a rugged case, and the mini XLR input allows you to connect a wide selection of microphones and instruments. A special jack lets you connect an optional external mute switch enabling the user to mute the audio signal even if the transmitter is hidden in the clothes.

A noiseless ON-MUTE/PRG-OFF switch and status LED add to the transmitter’s user-friendliness.

The new C 555 L head-worn microphone from AKG is rugged, extremely easy to use, and offers outstanding price/performance. The C 555 L is the ideal microphone for any handsfree application including gymnastics instruction, presentations, or onstage performance. The C 555 L rests securely and comfortably on the head, and can be attached to the left or right side of the behind-the-neck headband as desired. A transducer shock mount reduces handling noise to a minimum. The moisture shield prevents perspiration from penetrating into the transducer element, ensuring a high degree of humidity protection for the microphone.

The C 555 L 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 SR 450 diversity receiver is your best choice for cost-efficient, high-performance multichannel systems. Up to 12 channels* can be used simultaneously within the same subband and even large systems will work smoothly in environments hostile to RF transmission.

Being compatible with professional WMS 4000 antenna splitters, power supplies, and high quality antennas, the WMS 450 enables you to set up highly complex wireless systems. In Auto Setup mode, the receiver will scan the available bands, find an interference-free channel, and transmit the related frequency data to the assigned transmitter via infrared. This technique significantly reduces the time it takes to set up a multichannel system. A Rehearsal function identifying dead spots, a programmable display clearly indicating all important system parameters, twocolor display backlighting warning the user of critical conditions from a distance, and a transmitter battery status display on the receiver enhance reliability and add to ease of use.
