Wireless transmission system for instruments
The AKG WMS 470 Instrument Set B7 is designed for setting up large multi-channel systems. It consists of the SR 470 receiver and the PT 470 pocket transmitter with connections for guitar and bass. The SR 470 diversity receiver allows up to 16 channels to be operated simultaneously within a single frequency band. By combining several frequency bands, it is possible to create systems offering absolute operational reliability with a maximum of 48 links. Thanks to the automatic frequency selection, which finds and displays all available channels in a matter of seconds, the system is easy to use even for beginners. A pilot tone transmitted with the broadcast signal prevents background noise by ensuring the receiver only passes the audio signal once the transmitter has been detected. On the SR 470’s ‘ Display ’, a change in colour indicates critical operating conditions, such as ‘ z.B. ’ (transmitter battery low), low remaining battery life, audio signal peaks or low RF field strength.
PT 470 Pocket Transmitter
The PT 470 pocket transmitter can be used to connect instruments and all AKG microphones with a mini-XLR connector. A transmission power of up to 50 mW ensures perfect sound and transmission quality even over long distances. The long battery life results in a significant reduction in running costs.
Battery life
With just one lithium battery, the system can operate for up to 14 hours; with an alkaline battery, for approx. 6 hours. Using a rechargeable NiMH battery allows for up to 8 hours of operation. The remaining battery life is displayed on the pocket transmitter. A rechargeable battery can be charged directly in the transmitter via built-in charging contacts.
Transmission
Both the receiver and the transmitter operate within a switching bandwidth of up to 30 MHz (per frequency set) in the UHF frequency range from 500 MHz to 865 MHz. Within this switching bandwidth, the receive frequency can be selected from the pre-programmed frequency groups and sub-channels on the receiver or set directly in 25 kHz steps. All settings are transferred from the receiver to the transmitter via an infrared interface.
Compatibility
The WMS470 is compatible with the WMS4500 and WMS450 antenna systems. Thanks to the extensive range of accessories, large multi-channel systems can be set up quickly and easily.
