COMMANDS AND FUNCTIONS
AMPLIFIER PANEL (PIC.1)
1) "VOLUME" CONTROL
The knob regulates the diffuser's volume.
This control does not affect the output "LINK" levels.
2) "LIMITER" INDICATOR LIGHT
The "LIMITER" indicator light comes on red during start (for a few seconds) and
when the internal audio limiter engages. This avoids the amplifier's distortion and
protects the loudspeakers against overloads.
3) "POWER" INDICATOR LIGHT
The "POWER" indicator light comes on green to indicate that the amplifier is
switched on and it is working properly.
4) EQUALIZATION CONTROL
This control permits the equalization of the speaker.
The "FLAT" central position permits a linear sound reproduction of the speaker. By
turning the control towards "VOICE", the response curve of the speaker highlights
the mid frequencies while if the control is turned towards "MUSIC", the low and high
frequencies are highlighted.
This control does not affect the level of the output signal (link).
5) "BALANCED INPUTS LINK" CONNECTORS
These balanced inputs can be used to connect audio sources at line level (0dB)
(eg. preamplifier, mixer, recorder, CD player, musical instrument, ...).
The balanced connector is connected in parallel and can be used to send the audio
signal to other amplified speakers, recorders or supplementary amplifiers.
6) POWER SWITCH "POWER"
This switch can be used to switch the diffuser on and off.
7) POWER CABLE SOCKET "MAINS"
Used for connecting the power cable supplied.
8) FUSE CARRIER "FUSE"
Mains fuse housing.
9) VOLTAGE CHANGE "VOLTAGE SELECTOR"
For changing the power voltage of the speaker (240V/120V).
This switch is preset and protected by the manufacturer.

horizontal at 90° .
