WMS 400 WIRELESS SYSTEM

The new WMS 400 offers a unique combination of class-leading

audio quality with wide dynamic range, incredible ease of setup and

operation and low operating cost. Up to 24 WMS 400 systems can

be used simultaneously, so it is perfect for any small or medium-sized

application. Since WMS 400 uses the antenna components and other

accessories from the WMS 4000, it is possible to put together high-

performance, yet cost-effective custom multi-channel wireless sys-

tems.

WMS 4000 WIRELESS SYSTEM

The WMS 4000 is the ultimate wireless microphone system for

any application requiring the best audio quality, unbelievable flexibil-

ity and rock-solid reliability. The WMS 4000 system operates in four

30-MHz UHF bands with 1,200 frequencies in each band permitting

at least 50 systems to be operated simultaneously anywhere. With

120 dB of dynamic range, full 35 - 20,000 Hz response and an

incredible array of accessories for customization for any application,

the WMS 4000 delivers class-leading performance and true "hard-

wired" sound.

SR 4000 RECEIVER
