ince its introduction, the unique qualities of the Sony 800 Series UHF Wireless
Microphone System have been proved in many different applications. It has been
particularly successful in quality-critical applications such as broadcasting and
productions, where its attributes of wide audio dynamic range, low noise, stable RF
transmission and reception, and high reliability have been vital factors.
Building on this success, Sony now introduces an addition to the 800 Series UHF Wireless
Microphone family — the newly-developed WRT-847 UHF Synthesized Transmitter Unit together
with a range of five interchangeable microphone capsules. These five types of optional capsules
enable the WRT-847 to cover a very wide range of applications. The
CU-F780, CU-G780 and CU-E700 capsules are designed for vocal and
speech applications in broadcasting, live music performances and
concert halls, while the CU-E672 and CU-F117 options are suitable for
interviews in news gathering and field productions.
The WRT-847 UHF Synthesized Transmitter Unit is fully compatible
with existing Sony receiving systems, allowing flexible simultaneous
multi-channel operation.
