Precautions
•The unit is designed for use in ambient temperature range
of 0°C to 50°C (32°F to 122°F).
•Do not place the unit on or near heat sources, such as
lighting equipment, power amplifiers, or in a place subject
to direct sunlight or excessive moisture. In such places,
the external finish or internal parts of the unit may be
damaged.
•If the unit is used in a very humid or dusty place or in a
place subject to an active gas, clean its surface as well as
the connectors with a dry, soft cloth soon after use.
Lengthy use of the unit in such places or not cleaning it
after its use in such places may shorten its life.
•When cleaning the unit, never use organic solvents such
as thinners or benzine, which will damage the finish of the
unit.
•The unit has been factory adjusted precisely. Do not
tamper with its internal parts or attempt to repair it.

Overview
The WRT-808A is a transmitter which converts a hand-held
dynamic microphone into a wireless microphone, ensuring
excellent sound quality of the microphone itself and
providing the convenience especially for Electronic News
Gathering (ENG), live and other Electronic Field Production
(EFP) applications. Combining with 800 MHz band Sony
UHF wireless microphone system, use this highly reliable
transmitter for broadcast and movie production purpose.
Wireless Channels Selectable
The transmitter and tuner of the wireless microphone system
are classified by frequency band.
A 12-MHz frequency band (or two consecutive-numbered
TV channels, such as 68 and 69 of the WRT-808A/68
model) is assigned to each transmitter and tuner model.
In building a UHF wireless microphone system, be sure to
combine a transmitter and a tuner having the same TV
channel number.

Features
Easy selection of 94 channels
The PLL synthesized system assures easy selection of 94
channels and full compatibility with Sony 800 MHz series
wireless microphone system.
Easy and reliable connection
The WRT-808A can be adapted to a wide variety of wired
microphone which has a XLR audio connector. The reliable
connection assures the noise-free operation.
Compact and lightweight
High density mounting technology enables this compact and
light weight transmitter, to allow you to move anywhere for
Electronic News Gathering (ENG) and Electronic Field
Production (EFP).
Operation powered by easily available batteries
Approximately four hours of continuous operation is
ensured with two AA-size (LR6) alkaline batteries. By
virtue of DC-DC converter, consistent output power is
assured over the life of the batteries.
Battery status information on both transmitter and
tuner
To avoid the battery failure, the WRT-808A shows the
battery status with the LED indication in green, red and
flashing. About one hour before the battery exhausted, the
WRT-808A gives the battery information to make the alarm
on the tuner WRR-800A/801A/805A/850A.
LED indication of audio input
The AF/PEAK indicator allows you to comprehend the
condition of audio input level at a glance.
Continuous control of input attenuation
When an excessively strong audio signal is inputted, the
input level can be adjusted in the range of 0 to 50 dB
continuously.
When setting the 50 dB attenuation, the WRT-808A can
accept +4 dB (maximum 20 dB) line level input.
Selectable RF power output
You can select the RF output level either 50 mW or 10 mW
to suit the operating condition.

Channel Setting
Caution
Turn off the transmitter when setting the transmitting
channel to eliminate interference or noise on other wireless
equipment.
Each “Wireless Channel” is represented on the unit by a 2-
digit TV channel number followed by another 2-digit
number, for example: 69-05.
Set the channel select switches for the clicked position of
the desired channel number by using a screw driver.
The left switch selects the TV band and the 10’s digit of the
transmitting channel. The right switch selects the 1’s digit of
the transmitting channel.

Notes on batteries
•Use new alkaline batteries, and check the recommended
“ useby” date on the bottom of the batteries.
•Do not pair different types of batteries.
•Always replace the two batteries together.
•The batteries are not rechargeable.
•Be careful to install the batteries with the correct polarity.
•When not using the transmitter for a long period, remove
the batteries to avoid leakage. If the batteries do leak, clean
all leakage from the unit. Leakage left in the unit may cause
poor battery contact. If there seems to be poor battery
contact, consult your Sony dealer.

Notes
•Be sure to set the arrow mark of the channel select switch
to the clicked position of the desired channel number. If
the switch does not click on the channel number, the
desired channel may not be set on the unit.
•If the channel select switches are operated while the
transmitter is on, the POWER/BATT indicator flashes in
green as a warning.
•If you set to any channel other than those listed in
“Wireless Channel Lists” on pages L-1 to L-3, the
POWER/BATT indicator flashes in green as a warning.
•While the POWER/BATT indicator is flashing, the RF
output signal send from the transmitter becomes lower
than the usable level.
While POWER/BATT indicator on the transmitter is
flashing, the RF input indicator on the tuner may light, if
the transmitter locates near the tuner.
Though the RF input indicator lights on the tuner, the
Sony tuner (equipped with muting function) makes neither
noise nor audio output.
•Make sure that the channel selected is the same as that
selected on the tuner used in the same system.
•If there is a TV broadcasting station near by, do not use
the station's channel.

If noise is heard
Depending on the environment where the system is
installed, outside noise or radio wave may disrupt the
transmission of certain channels.
To select a channel under this circumstance, turn off the
transmitter. Select a channel on the tuner, at which the RF
indicator is off. (A channel free from noise or radio wave
interference is selected.) Then, set the same channel on the
transmitter.
