The AKG WMS 450 Wireless Guitar Set includes the PT 450 bodypack tranmitter, SR 450 receiver, MKG L instrument cable, belt clip, AA size battery, 2 antennas, rack mounting kit, and power supply. 

The AKG WMS 450 is your best choice for any application calling for a solution that is more flexible than a simple plug-and-play system yet easy to set up and operate. The WMS 450 provides a cost-efficient, high-performance solution for situations where several radio mics will be used simultaneously, including gigs at small clubs, small stages, or regional events. Using several single-channel systems has its limitations and may simply be too much for the available radio band. 

PT 450 bodypack transmitter< BR/> 
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. 

SR 450 receiver 

The SR 450 diversity receiver is a cost-efficient, high-performance multichannel system. 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 multi-channel system. A Rehearsal function identifying dead spots, a programmable display clearly indicating all important system parameters, two color 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.
