Introduction
Coupling with the CU-F780, CU-G780, CU-E700, CU-E672
or CU-F117 Sony Microphone Capsule Unit, the WRT-847A /
847B UHF-synthesized transmitter unit makes up a UHF-
synthesized wireless microphone to be used in a UHF-
synthesized wireless microphone system.
For vocal concentration, operate the WRT-847A/ 847B in
conjunction with the WRR-802A/850A, MB-806A with
WRU-806A UHF Synthesized Tuner. For vocal and
interview use, operate the WRT-847A/8 47B in conjunction
with the WRR-805A/855A UHF Synthesized Tuner.
The microphone/transmitter and tuners of the wireless
microphone system are classified by frequency band.
A 24 MHz frequency band (a 14 MHz frequency band:
model available in Australia) is assigned to each
microphone/transmitter and tuner model.
In building up a UHF wireless microphone system, be sure
to combine a microphone/transmitter and a tuner having the
same TV channel number.
