AKG Showcases Revolutionary DMS 700 Digital Wireless System At NAB 2009

20 April, 2009, Las Vegas, Nevada, United States

AKG is showcasing the DMS 700 digital wireless microphone system at NAB, offering users a state of the art feature set including digital audio encryption, ultra wide tuning range and high channel count in a simple to use 19” chassis. Ideal for live sound reinforcement, conference facilities, courtrooms and houses of worship, the DMS 700 is a revolutionary wireless solution designed for the future as it operates with two frequency bands with each band providing a tuning range of up to 155 MHz of receivers and transmitters giving the user extended flexibility in today’s crowded RF environment.

The clean digital audio transmission eliminates the distortion and significant noise levels at the higher audio frequencies that is typically produced by analog systems. The DMS 700 offers 155 MHz of bandwidth, which provides a robust and versatile operation. The 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 absolutely confidential.

Featuring the ability to operate up to 100 channels simultaneously, the digital audio transmission system provides a better resistance to interference from other transmissions and an infrared link between receiver and transmitter offers a quick system setup for easy and user-friendly operation.

DSR 700 Digital Stationary Receiver

The 1U 19” rack mountable DSR 700 digital receiver features encryption and 155 MHz tuning range ensuring future operation. The internal digital signal processor provides an array of audio features such as a low cut, 3-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 features Harman HiQnet™ allowing it to be networked with Crown® amps and JBL® speakers and other Harman Products which also allows for easy software updates of all system components.

DHT 700 Digital Handheld Transmitter

The DHT700 Transmitter has a rugged metal housing, a built-in helical antenna and 50mW RF output power that provides for optimal and reliable transmission. The DHT 700 features AKG’s Top Selling D5 dynamic microphone capsule for lead and backing vocals. The patented Laminate Varimotion™ diaphragm accompanies the supercardiod polar pattern to provide users with higher gain before feedback than typical hand held vocal mics. AKG’s C5 condenser microphone capsule with a cardioid polar pattern is also available.

DPT 700 Digital Bodypack Transmitter

The DPT 700 Bodypack transmitter accepts both microphone and line-level input signals with no need to adjust the input sensitivity. This unique feature guarantees a failure-proof operation and the professional TB3M audio input supports a broad range of headsets, lavalieres and instrument microphones. AKG’s legendary battery life of eight hours of operation from two regular AA size batteries remains consistent in the DPT700 as with other AKG wireless systems.

CU 700 Charging Unit

AKG’s CU 700 is a fast charger that rapidly charges the rechargeable batteries inside the transmitter without damaging the cells' elements. The microprocessor-controlled charger determines the optimum charge current and has a cooling fan to help keep the temperature of the cells in a controlled environment. Charging is terminated when both batteries are fully charged. The CU 700 charger uses the DC Pulse Technology in which a pulse is fed to the battery with a strictly controlled rise time, pulse width, pulse repetition rate and amplitude. With pulse charging, high instantaneous voltages can be applied without overheating the battery.
