Note

When the PROTECTION indicator lights up

The protection circuit triggers and the PROTECTION indicator
lights up in following conditions. In this case, the speaker and
amplifier are protected by cutting output.

• When direct-current voltage appears in the SPEAKER
terminal from a malfunction.

• When rated temperature of amplifier internal heat sink is
exceeded.

• When impedance of the connected speaker is too low, or
when speaker outputs are shorted.

When the above happens, turn off the POWER switch, find
and fix the cause of the problem, and restart.

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.
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.
(the max supply current is 20 mA)

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.

2 Tuner unit slot (MIC1, MIC2)

These are for installation of the optional 800MHz
wireless tuner unit WRU-801A/ WRU-806A. Up to
two units can be installed. (Refer to page 9 how to
install.)
Before installation, read carefully also the instructions
of WRU-801A/ WRU-806A.

Inserting batteries into the remote

You can control this unit with using the supplied remote.
Insert two R6 (size AA) batteries by matching the + and –
on the batteries. When using the remote, point it at the
remote sensor on the equipment.

When to replace batteries

With normal use, the batteries should last for about six
months. When the remote no longer operates the equip­ment, replace all the batteries with new ones.

Notes

• Do not leave the remote near an extremely hot or humid
place.

• Do not drop any foreign object into the remote casing,
particularly when replacing the batteries.

• Do not expose the remote sensor to direct sunlight or lighting
apparatuses. Doing so may cause a malfunction.

• If you don't use the remote for an extended period of time,
remove the batteries to avoid possible damage from battery
leakage and corrosion.

Installation of The Tuner Unit

1 Turn off the power of this unit.
2 Remove the tuner cover.
3 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 compart­ment.
Do not insert or remove the tuner
unit while the power is on. This
may be cause of noise or
malfunction of the connector.

Tuner 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.

NOTICE

To prevent breakdown or injury, do not put your hand
inside of the slot except when you install or remove the
tuner unit.

Troubleshooting

Power will not turned on. • Is the power cord unplugged?

• Is the curcuit breaker working? (See page 7.)

No sound. • Does the EMG indicator turn off? (See pages 4 and 7.)

• Does the PROTECTION indicator turn off? (See page 4.)

No sound is output to MASTER OUTPUT • Has the ASSIGN switch been set to OFF? (See page 8.)
or SPEAKER terminals from microphone. • Has the MIC GROUP knob been set to –∞? (See page 5.)

No sound from wireless microphone. • Is the channels of microphone and tuner unit matching?

And does the RF/SIGNAL indicator light on when the microphone
is turned on? (See page 9.)

• Is the antenna connected correctly?
Sound is heard in monaural. Has the MODE switch been set to STEREO? (See page 8.)
Sound is distorted. Is the CLIP indicator lighting on? (See page 4.)
No sound from MIC4. Has another microphone been connected to MIC4 terminal

on the front panel?(See page 4.)

Wireless remote control does not function. •Has a plug been connected to CONTROL-S input terminal

on the rear panel?(See page 6.)

• Are the remote control batteries dead?(See page 8.)
Signal of the ST2 can not be recorded. Signal from ST2 does not output to REC OUTPUT. (See page 5.)
