The speaker is made of 15mm light multilayer wood, coated in
PVC with protection frames on top and bottom in
polypropylene; the four handles located on the sides of the
speaker enabling easy transportation .
In the bottom of the box there is retractable adjustable foot (in
height) to inclinate the tilt angle up to a max. of 7°.
This allows to direct the sound radiation without using
additional supports.
COMMANDS AND FUNCTIONS (reference page 29)
1) “BALANCED INPUT” CONNECTOR
These balanced inputs can be used to connect balanced or unbalanced microphones
or audio sources at line level (0dB) (eg. preamplifier, mixer, recorder, CD player,
musical instrument, ...).
2) “LINK” - “INPUT-LINK” CONNECTORS
The balanced connector is connected in
and can be used to send
the audio signal to other amplified speakers, recorders or supplementary amplifiers.
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 medium
level of -20dB).
parallel with input (1)
5) “READY” INDICATOR LIGHT
This indicator shows green to indicate the speaker normal operating conditions.
6) “VOLUME” INPUT SENSITIVITY CONTROL
This control adjusts the sensitivity of the signal amplifier input.
This control does not affect the “LINK” - “INPUT - LINK” output level.
7) “EQ” SWITCH
This two-way switch allows to choose between two different equalizzations.
The “FLAT” position allows linear response of the speaker, which is mainly suitable for
the “live” application.
8) “INPUT SENS” SWITCH
Position the switch in LINE to use a line level source (0 dB) or MIC to use a
microphone.
9) FUSE CARRIER “FUSE”
Mains protection fuse housing. The fuse specifications are found in the data plate of
the apparatus. In case of failure to replace it with one of the same type and value
specified.
10) "MAINS INPUT" POWER SOCKET
To connecting the power cable provided and performs the function of mains switch.
The connector used for mains connection is a POWER CON® (blue) socket.
In the normal operating the led (READY) is steady turned on.
11) “MAINS LINK” OUTPUT POWER SOCKET
To linking the mains power. The output is connected in parallel with input (10) and can
be used to power another active speaker.
The connector is a POWER CON® (grey) socket.
The “BOOST” position emphasizes low frequencies by limiting medium and favoring
the recorded sound tracks reproduction.
SIGMA S118
® The subwoofer S118 is equipped with bi-amplifier DIGIPRO
G2 bridge connected, which delivering 1400W .
S115 is equipped with woofer 18”, with aluminium basket and
voice coil 4” (100mm).
The speaker is made of 15mm light multilayer wood, coated in

polypropylene; the two handles located on the sides of the
speaker enabling easy transportation .
In the top of the box there is a metal pole mount cup (M20).

5) “READY” INDICATOR LIGHT
This indicator shows green to indicate the speaker normal operating conditions.
6) “SUBWOOFER VOLUME” INPUT SENSITIVITY CONTROL
This control adjusts the sensitivity of the signal amplifier input.
This control does not affect the “BALANCED OUTPUT” output level.
7) “X-OVER” SWITCH
8) “XOVER”-“FULL RANGE” SWITCH
9) FUSE CARRIER “FUSE”
Mains protection fuse housing. The fuse specifications are found in the data plate of
the apparatus. In case of failure to replace it with one of the same type and value
specified.
10) "MAINS INPUT" POWER SOCKET
To connecting the power cable provided and performs the function of mains switch.
The connector used for mains connection is a POWER CON® (blue) socket.
In the normal operating the led (READY) is steady turned on.
11) “MAINS LINK” OUTPUT POWER SOCKET
To linking the mains power. The output is connected in parallel with input (10) and
can be used to power another active speaker.
The connector is a POWER CON® (grey) socket.
This switch enables to select the crossover frequency between subwoofer and
loudspeaker connected to the “Balanced Output” (2). It is possible to select either
100Hz and 80Hz as cutoff frequency.
This switch enables to select the signal to be redirected to the “BALANCED
OUTPUT”.
The position “X-OVER” enables to send the input signal, cut at the crossover
frequency selected by means of the selector (7) to an amplified loudspeaker.
The “FULL RANGE” position enables to send the same input signal to another
subwoofer.

1) “BALANCED MAIN INPUT” CONNECTOR
These balanced inputs can be used to connect balanced or unbalanced microphones
or audio sources at line level (0dB) (eg. preamplifier, mixer, recorder, CD player,
musical instrument, ...).
2) “BALANCED OUTPUT” CONNECTORS
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 medium
level of -20dB).
This connector is used to send the signal to another subwoofer or to an amplified
loudspeaker.
From this connector it is possible to pick up the Full-Range or High Pass signal,
operating the selector “XOVER”-”FULL RANGE” (8).
