AKG has combined the WMS 450 receiver and D 5 dynamic vocal microphone form the perfect professional wireless dynamic vocal microphone system. 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 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. Combined with the D 5 dynamic vocal microphone for lead and backing vocals delivers a powerful sound even on the noisiest stage. Its supercardioid polar pattern ensures maximum gain before feedback. The D 5 stands for a crisp sound that cuts through every mix. The D 5 dynamic vocal microphone for lead and backing vocals delivers a powerful sound even on the noisiest stage.

D 5 microphone element

The D 5 dynamic vocal microphone for lead and backing vocals delivers a powerful sound even on the noisiest stage. Its supercardioid polar pattern ensures maximum gain before feedback. The D 5 stands for a crisp sound that cuts through every mix.

AKG made the first microphone diaphragm ever whose thickness varies across its diameter. The new Laminated Varimotion diaphragm deep-drawing process allows the diaphragm itself to be fine-tuned with no extra tuning resonators, leading to a quantum leap in audio performance.

The dual shock mount eliminates any kind of mechanical noise for trouble-free live use. The audience will hear nothing but the pristine sound of your voice!

Features:

• Extremely rugged vocal/speech microphone
• Available with or without on/off switch
• Patented AKG Laminated Varimotion diaphragm
• Spring steel wire-mesh grill

HT 450 handheld transmitter

The HT 450 is a high-performance, rugged handheld 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 HT 450 handheld transmitter is available with the dynamic microphone element D 5 or the condenser microphone element C 5.

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

Features:

• Available as D 5 or C 5 version with the outstanding AKG sound
  – Maximized rejection against feedback
  – Improved handling noise sensibility
• Spring Steel elastic wire mesh cap for safe protection of the capsule element
• New rugged finish for professional applications
• Easy configuration through optimized Infrared data download from receiver
• Lowest operating costs: Up to 8 hours with ONE Battery (AA)
• Unique Battery Status Display
• Integrated Charging Contacts
• Ergonomically Designed Shape

SR 450 receiver

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.

• Best sound in class!
• All metal case with rugged finish
• Easy set up of up to 12 channels per frequency band
• Programmable Status Display with Two-Color Backlight
• Integrated frequency scanner with country specific frequency management database
