1 ANT IN (antenna input) A/B terminals
Use to connect the antenna for wireless tuner. When
installing the tuner unit, connect the optional UHF
antenna WRU-801A/WRU-806A.
3 REMOTE terminals
CONTROL S input terminal
Connect to the S output terminal of another equip-
ment.
When this terminal is plugged in, the sensor of this
unit is not functioning.
As these terminals output DC power of 9V for the
booster inside of the connected antenna, connection of
any antenna other than stated above may cause bad
performance or a malfunction.
Input signals are directly output from control S output
terminal.
(the max supply current is 20 mA)
CONTROL S output terminal
This terminal outputs the signal input from CON-
TROL S input terminal or the sensor.
Note
Before locating and connecting the antenna, read carefully the
instructions supplied with the antenna.
Incorrect location of the antenna may cause a bad reception
such as intermittent sounds. If it is not easy to relocate the
antenna after location, check carefully if the performance will
be satisfied with the location.
Use the coaxial cable of impedance 50 ohms/75 ohms (5D-FB,
5C-2V, etc.). The cable can be extended up to about 50 m with
5D-FB, and up to about 25 m with 5C-2V.

Use to control this unit with a personal computer.
Connecting to a computer
Connect the computer to the RS-232C terminal of this
unit with a cross cable.

1 - 4 terminals for condenser microphones.
When it is ON, DC+48V is output for the MIC
terminals except for the MIC4 on the front panel.
Select one of following two ways of connection as
follows.
Notes
• Make sure to turn the MIC fader toward minimum before
connecting or disconnecting any cable or turning the +48
button to ON.
• Make sure to connect a line equipment to ST1 to ST3 inputs.
• When using a microphone powered by +48V and a dynamic
microphone simultaneously, the dynamic microphone may
not show its performance to the full.

emergency broadcast facilities.
0 ST1/ST2 input terminals
Use them for inputs from audio equipment.
Connect a playback equipment mainly to ST1 and a
record player to ST2.
When DC24V is cut off, all AUDIO outputs of this
unit will be cut off.

3
Turn off the power of this unit.
4
Fix the tuner cover.
After installation of the tuner unit, turn on the power
of the unit and turn on the power of the wireless
microphone to check it is receiving. While receiving,
the RF/SIGNAL indicator lights up. Note that the RF/
SIGNAL indicator will not light up when the setting
channel of the microphone is different from the setting
of the tuner unit, or when the microphone power is
consumed.
Remove the tuner cover.
Check the up and down sides of the tuner unit, and
insert it into the slot.
The upper slot corresponds to MIC1 and the lower slot
to MIC2. (Set the group and channel of the tuner unit
to same as wireless microphone's one.)
Insert it deeply into the compart-
ment.
Do not insert or remove the tuner
unit while the power is on. This
may be cause of noise or
malfunction of the connector.
NOTICE
To prevent breakdown or injury, do not put your hand
inside of the slot except when you install or remove the
tuner unit.
