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.
U68 model
A 794-806 MHz frequency band is assigned to the WRT808A/68 model, permitting it to operate on any of 94 carrier
frequencies in 125-kHz steps of Sony original channel plan
in the range of TV channels 68 and 69.
For the selectable channels, see “Wireless Channel Lists” on
page L-1.
U66 model
A 782-794MHz frequency band is assigned to the WRT808A/66 model, permitting it to operate on any of 94 carrier
frequencies in 125-kHz steps of Sony original channel plan
in the range of TV channels 66 and 67.
For the selectable channels, see “Wireless Channel Lists” on
page L-2.
U64 model
A 770-782 MHz frequency band is assigned to the WRT808A/64 model, permitting it to operate on any of 94 carrier
frequencies in 125-kHz steps of Sony original channel plan
in the range of TV channels 64 and 65.
For the selectable channels, see “Wireless Channel Lists” on
page L-3.

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.
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.
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.
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.

Power Supply
The transmitter can operate on two LR6 (size AA) alkaline
batteries continuously for about 4 hours at 25°C (77°F).
Installing the batteries
Two LR6 (size AA)
alkaline batteries
1 Turn the battery-compartment screw counterclockwise.
2 Match the polarities and insert the batteries.
3 Close the lid.
Battery indication
When you turn the power on, the POWER/BATT indicator
lights in green.
While in operation, the POWER/BATT indicator shows the
battery condition as shown below.
Lights in green: Good
Lights in red: The battery level is low. About one hour
is left for continuous operation.
Flashing in red: The batteries are almost exhausted.
The unit does not work.
Promptly replace the batteries when the POWER/BATT
indicator lights in red or flashes.
When the POWER/BATT indicator lights in red on this unit,
the BATT indication on the tuner (WRR-800A/801A/805A/
850A) starts flashing as a warning.
Note
The indication may be incorrect if the batteries are not new
when installed. If you plan to use the transmitter for a long
US
8
period, it is best to replace the batteries with new ones.
Channel Setting
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 l ong 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.
Caution
Turn off the transmitter when setting the transmitting
channel to eliminate interference or noise on other wireless
equipment.

Microphone System Operation
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.
Microphone connection
Sony microphones F-780/740/730/720/710, etc.
Attach a microphone
to the unit directly or
use a microphone
cable with XLR-3-11
and XLR-3-12 type
connectors.
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.
To dettach a
microphone,
press the
microphone
release
button.

Use of RF power output switch
The RF power output switch (located inside of the battery
compartment) selects the RF power output either 50 mW or
10 mW. In normal use, set the switch to “50” (factory preset
position).
50 mW output is suitable for optimum transmission over
long working distance.
10 mW output will be suitable for multi-channel operation
to eliminate the interference.
Use of input LEVEL control
When the AF/PEAK indicator lights in green continuously,
the supplied audio signal is continuously over the reference
level. If this occurs, use the input LEVEL control to avoid
sound distortion.
By turning the control to “–10”, the WRT-808A provides 50
dB input attenuation and can be inputted +4 dB (maximum
20 dB) line level signal.
Notes on microphone system operation
To operate with two or more channels, maintain a distance
•
of at least 30 cm (one ft.) between each pair of
transmitters.
For details of operation with two or more channels, refer
to the Operating Instructions for the WRR-800A/801A/
805A, etc.
Ensure that the transmitter set to channels not being used
•
are either turned off or set to the minimum output level.
When powering the transmitter on or off, to keep the noise
•
to a minimum, set the audio output level from the tuner or
mixer to a minimum.
Powering the transmitter on without checking the channel
•
selection first may interfere with the operation of other
microphones/transmitters, if the current setting is already
being used.
To prevent noise generation, keep the transmitters at least
•
3m (10 feet) away from the tuner antennas when the
system is operated using a group which allows selection of
up to 11 channels.
Do not grip the transmitter while using as it
•
will significantly degrade good
performance, causing dropouts, etc. Hold
the microphone itself as shown.
