AKG WMS400 UHF Headset Wireless with C444L Microphone

Product Description

The AKG WMS 400 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 400 provides cost-efficient, high-performance solutions 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.

SR 400
Integrated frequency scanner with frequency management database

Up to 12 channels can be used simultaneously in each subband

Infrared data transmission link

Rehearsal function for finding dead spots

Programmable warning functions using two-color display backlighting

The SR 400 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 400 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.

PT 400
Infrared data download link for quick setup

Battery status display and data transmission

Connector for external mute switch

Integrated charging contacts

Extremely compact case

Professional mini XLR audio input

The PT 400 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 400 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.

C 444L
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. zZounds is an authorized dealer of AKG products.
