AKG Showcases Wireless at NAB

AKG showcased its DMS 700 digital wireless microphone system at the NAB 2009 Show. The system offers users features such as digital audio encryption, ultra-wide tuning range, and high channel count within a 19-inch chassis.

AKG showcased its DMS 700 digital wireless microphone system at last week's NAB 2009 Show in Las Vegas. The system offers users features such as digital audio encryption, ultra-wide tuning range, and high channel count within a 19-inch chassis.

Designed for flexibility within the current crowded RF environment, the DMS 700 operates with two frequency bands, each providing a tuning range of up to 155 MHz. The company says its clean digital audio transmission eliminates the distortion and significant noise levels at the higher audio frequencies typically produced by analog systems.

The DMS 700's encrypted digital audio transmission enables users to broadcast sensitive audio information, and each channel can be secured with its own encryption key to keep the information confidential. With the ability to operate up to 100 channels simultaneously, the company says the digital audio transmission system also provides a better resistance to interference from other transmissions, while an infrared link between receiver and transmitter offers a quick system setup for easy operation.

The 1RU DSR 700 digital receiver's internal digital signal processor provides a low-cut, three-band equalizer, dbx compressor, and dbx limiter. The built-in spectrum analyzer displays the frequency range to enhance the operation and control of the radio spectrum. The DSR 700 also features Harman HiQnet, which allows it to be networked with Crown amps and JBL loudspeakers, along with other Harman products.

The DTH 700 digital handheld transmitter has a rugged metal enclosure, a built-in helical antenna, and 50 mW RF output power that supports optimal and reliable transmission. The DHT 700 features AKG's D5 dynamic microphone capsule for lead and backing vocals. The Laminate Varimotion diaphragm accompanies the supercardioid polar pattern to provide users with high gain before feedback. AKG's C5 condenser microphone capsule with a cardioid polar pattern is also available.

The DPT 700 bodypack transmitter accepts both microphone and line-level input signals without needing to adjust the input sensitivity. This feature guarantees a failure-proof operation, according to the company.

The CU 700 charging unit charges the transmitter batteries without damaging the cells' elements, says AKG. The microprocessor-controlled charger determines the best charge current and has a cooling fan to help keep the temperature of the cells in a controlled environment. Charging automatically ends when both batteries are fully charged.
