Introduction; Transmitting Channel Band; Features - Sony WRT-807B Bedienungsanletung

Introduction

The WRT-807B is a UHF-synthesized wireless microphone
for use in a 800-MHz band UHF-synthesized wireless
microphone system.
The WRT-807B operates in conjunction with the MB-806A
with WRU-806B UHF Synthesized Tuner Unit for vocal
concentration.
The WRT-807B can be also used with existing Sony
wireless microphone systems consisting of the WRT-805B/
855B UHF Synthesized Transmitter and WRR-805B/855B/
862B UHF Synthesized Tuner, etc.

Transmitting Channel Band

The microphone/transmitter and tuners of wireless
microphone systems are classified by frequency band.
A 24-MHz frequency band is assigned to each microphone/
transmitter and tuner model.
In building a UHF wireless microphone system, be sure to
pair a microphone/transmitter with a tuner that has the same
TV channel number.

Features

Phase Locked Loop (PLL) synthesized system
The WRT-807B features a refined phase locked loop (PLL)
synthesizer circuit.
POWER switch with holding function
The POWER switch can be locked in the ON position to
protect against accidental power cut-offs.
Low-battery notification on tuner
When the microphone battery is low, the microphone sends a
warning to the WRR-805B/862B/WRU-806B in the form of
"Battery status information."
This information is sent to the WRR-805B/862B/WRU-
806B about one hour before the battery goes dead to allow
the battery to be safely replaced.
When the WRR-805B/862B/WRU-806B receives this
information, the LED on tuner panel starts to flash.
Powered by readily available battery type
The built-in, high-efficiency DC-DC converter provides
about 5 hours of continuous and stable operation with just a
single LR6 (size-AA) alkaline battery.
