Main power supply linking
On the rear of the speaker, a Neutrik POWER CON® connector (grey) offers linking the
mains power supply.
This socket links the power supply to another speaker, thereby reducing the direct
connections to the mains. Maximum amplifier input power is shown on the amplifier panel.
The maximum number of speakers connected together varies of max input power and of
the maximum allowed current of the first power socket.
LOUDSPEAKER INSTALLATION
WARNING
Make sure that the loudspeaker is securely installed in a stable position to avoid any
injuries or damages to persons or property.
For safety reasons do not place one loudspeaker on top of another without proper
fastening systems.
If you use the loudspeakers outdoors avoid places that are exposed to bad weather.
The loudspeaker is supplied by the manufacturer company for use in support
WARNING
Never use the handle to hang the speaker!

CONTROLS AND FUNCTIONS (FIG.1)
1)
" BALANCED INPUT 1" AND " BALANCED INPUT 2"INPUT CONNECTORS
Balanced inputs at line level. Accept "XLR" sockets.
2)
" OUT 1 " AND " OUT 2 " OUTPUT CONNECTORS
The "XLR" connectors be used to send the input audio signal to another amplified
speaker.
The output signal is selected by "LINK/XOVER" (10) switch.
3)
"LIMITER" INDICATOR LIGHT
This indicator shows red to indicate that the internal limiter circuit has tripped.
This prevents amplifier distortion and protects the speakers against overloads.
4)
"SIGNAL" INDICATOR LIGHT
This indicator shows green to indicate the presence of the audio signal (at a level of -
20dB).
5)
"MUTE" INDICATOR LIGHT
This yellow indicator indicates amplifier status.
The LED is off in normal operating conditions.
6)
"READY" INDICATOR LIGHT
This indicator shows green to indicate that the main power voltage is correct.
The LED shows green normal operating conditions
7)
"INPUT SENS" INPUT SENSITIVITY CONTROL
This control adjusts the sensitivity of the signal amplifier input.
This control does not affect the " OUT 1 " and " OUT 2 " outputs levels
8)
"PHASE" SWITCH
This two-position switch permits reversing the audio signals phase of the
subwoofer by 180°.
Reversing makes it easier to optimise the reproduction of the low frequencies even
in the most difficult installation situations. After completing installation, play a music
track and activate the switch to achieve the best sound reproduction at low
frequencies.
9)
"XOVER" SWITCH
T h i s s w i t c h p e r m i t s s e l e c t i n g t h e c r o s s o v e r f r e q u e n c y b e t w e e n t h e
subwoofer and the speakers connected to the "OUT 1 " and "OUT 2 " outputs.
Choice depends on the type of speaker used for reproduction of mid-high
frequencies.
For speakers with 12" cones, it is best to use 120Hz, while with 15" speakers 90Hz.
10)
"LINK/XOVER" SWITCH
This switch allows to select the signal type to send "OUT 1 " and "OUT 2 " outputs.
The "LINK" position allows to link the same input signal.
The "XOVER" position allows to send input signal according to crossover frequency
select by XOVER (9) switch.
11)
"MAINS INPUT" POWER SOCKET
For connecting the power cable provided.
The connector used for mains connection is a POWER CON® (blue) socket
12)
"MAINS OUTPUT LINK" POWER SOCKET
For linking the mains power. The output is connected in parallel with input (11) and
can be used to power another active speaker.
The connector is a POWER CON® (grey) socket
13)
"MAINS FUSE" FUSE CARRIER
Mains fuse housing.
