Lights green when a signal is outputting from
this speaker or Line output.
2. Line/Mic input signal indicator (green, red)
Lights green when a signal is input to Line/
Mic input. Lights red when the input signal
level is too high.
3. Line/Mic input volume control
Adjusts the volume level of the Line/
Mic input. Rotate this volume control
clockwise to increase the volume level and
counterclockwise to decrease it.
Set this volume not to make the Line/Mic
input signal indicator (2) light up in red.

Set this switch to MIC when connecting a
microphone, and to LINE when connecting
a general sound source device other than a
microphone.
Default setting: LINE
• PAD switch (Switch 2)
Enables or disables the microphone input
pad. When the input level is high, set the
PAD to –20 dB. Default setting: 0 dB

power to the microphone connected to Line/
Mic input terminals (10). Phantom power is
a 12 V DC.
Default setting: OFF
7. Control input terminals
Allows input of control signals from
connected external equipment to enable
actions set in the Event settings.
8. Functional ground terminal
If excessive noise is produced when
the speaker is connected to external
equipment, connect this terminal to the
external equipment’s functional ground
terminal, potentially minimizing the noise
level.

9. Control output terminals
Allows control of external equipment in
synchronization with the unit operation.
10. Line/Mic input terminals
Connects with a microphone or sound
source device. This can be used as
an audio input during SIP calls, or for
monitoring VMS broadcast.
Adjust with the switches of the DIP
switch according to the output level of the
connected device.
11. Line output terminals
Connects with an external amplifier etc.
and outputs the same audio as the speaker
output.
