control.
If this sensor is covered by something, the remote
control may not function correctly. Place the unit so
that the sensor will be easy to receive the remote
control signal.
3ECHO/AUX SEND knob
It adjusts the mixed signals after each channel fader
and outputs to the ECHO SEND terminal.
4RF/SIGNAL indicators
They light up regardless of the position of channel
fader when sound signal of more than -20dB to the
standard input level are input.
As for MIC 1/MIC 2 would be light up when it
received the signal while the wireless tuner unit is
installed and switch of the microphone is turned on.
5ECHO RETURN switch

input are assigned to L/R and Rec Bus.
6MUTING button
Use muting outputs from MASTER OUTPUT,
MASTER INSERT, ECHO SEND, MIC GROUP
OUT, and SPEAKER output terminals.
7CLIP indicator
Too high an output level will cause signal distortion
and make the CLIP indicator light up. When this
happens, lower the MASTER volume or the MIC/
LINE level knob until the indicator turns off. If too
much signal output for an extended period, it may
cause the equipment to overheat or to damage the
speakers.
8PROTECTION indicator
It lights up while the protection circuit is working.
When the power is turned on, it also lights up for few
seconds and it turns off when the amplifier become
stable.
9EMG indicator
It lights up when the unit receives a signal from the
emergency broadcast facilities and turns to standby.
As for EMG, refer to P. 75.
0+48V indicator
It lights up while the DC+48V is supplied through the
MIC input terminal.
!¡ MASTER VOLUME
Use to adjust the volume of MASTER OUTPUT and
SPEAKER terminal.
!™ MIC 4 terminal
This is input terminal in front for wired microphone.
If the wired microphones are connected to the MIC 4
terminals both at front and rear panel, the front input

Installation of The Tuner Unit
1Turn off the power of this unit.
2Remove the tuner cover.
3Check 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.)
NOTICE
To prevent breakdown or injury, do not put your hand
inside of the slot except when you install or remove the
tuner unit.
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.
4Fix 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.
Notes
Take the following precautions to prevent interference
and noise.
•If there is a TV broadcasting station nearby, to avoid
possible interference from its broadcasting, do not
use that station's channel.
•When simultaneously using two tuners, always set
the tuners to different channels within the same group
(other than group 00).
•Please make a choice of model in accordance with
your area to use picking up an unused TV channel.
•Make sure that the channel selected on the micro-
phone is the same as that selected on the tuner being
used in the same system.
