ON / OFF
A sound system should be switched on sequentially. Switch on the self-powered units last in your sound
system (switch on the subwoofer before the mid-high system). Switch on the sound sources such as CD
players or turntables, then the mixer, then the processors, and finally the self-powered unit. If you have
several units, it is recommended that you switch them on sequentially one at a time.
Follow the inverse order when switching off, turning self-powered units off before any other element in the
sound system.
Disconnect the device by removing the mains connector from the mains socket. The mains connector
and mains socket must always be freely accessible and never covered or blocked in any way.
The models use a power cable equipped with a Neutrik PowerCon TRUE1 connector. Power can be
daisy chained via the TRUE1 output connector (see details on product label).
IMPORTANT: Do not disconnect the unit while in use.
Ensure that the device is disconnected from the mains by observing that the ON LED is turned off. Please
note that the ON LED can stay on for several seconds after the mains power has been disconnected.
Overload indicator
This device has a SIGNAL/LIMIT indicator. The
red light indicates the signal is excessive.
The indicator should not be lit continuously.
This distorts the signal (quickly fatiguing your ears)
and may damage the speakers.
Overheating
This equipment does not normally overheat
during normal conditions of use. When overheating
occurs, the unit protects itself. You should then
find out why and if necessary contact an
authorised dealer for technical assistance.
Normally it is enough just to let the unit cool
down after you have corrected the problem so that
the system functions properly again.
Equalisation
The unit does not need extreme settings of
equalisation to produce quality sound. Avoid high
levels of gain on the equalisers. Gain values above
+3 dB on a console’s EQ are not recommended.
Low mains voltage
If mains voltage falls below the shutdown
voltage for the unit, it will stop playing. When
acceptable levels are regained, the unit will switch
back on automatically.
The SF-30A recognised the value of mains
automatically. The unit works from 80V to 260V
(both rms).

Cardioid Preset
This unique feature facilitates the configuration of two or three units to create a cardioid response pattern.
This is useful in situations where on-stage bass level projected from the subs needs to be kept to a
minimum.
To set-up a cardioid configuration with two stacked units, place the bottom unit facing the audience and
the top box facing the stage. Set the controls for level, polarity and cut-off frequency identically on both units.
Daisy-chain the signal from one unit to the other (do not activate the satellite output high-pass filter). Activate
the Cardioid Preset button on the box facing the stage. This provides the level and phase adjustments
necessary to cancel the rear projected sound waves “cleaning” the stage of unwanted bass.
To assemble a cardioid configuration with three stacked units, the procedure is basically the same. Place
the lower and top boxes facing the audience, the middle box facing the stage. Daisy-chain the signal, make
sure the level, polarity and cut-off frequency are the same on all the boxes and lastly, activate the Cardioid
Preset button on the box facing the stage.
There are 4 cut frequencies available: 50, 63, 80 and 100 Hz.

Troubleshooting
PROBLEM
No sound from the unit. The
SIGNAL LED does not light up.
Full power cannot be obtained. The
LIMIT LED never lights up.
Sound is distorted. The LIMIT LED is
not on, or only lights up occasionally.
Sound is distorted and very loud
and LIMIT LED lights up.
Hum or buzz when a mixer is
connected to the unit.
Hum or buzz when using lighting
controls in the same building.
The ON LED does not light up when
the mains connector is connected
and the unit is switched to ON.
CAUSE
1 – The signal source is sending no
signal.
2 – Defective cable.
1 - The signal source does not have
a hot enough output.
2 - If the connections are correct, It
might be overheating
1 - The mixer or signal source is
distorting.
1 - The system is overloaded and
has reached maximum power.
1.– The console probably has un-
balanced outputs. You may be using
an incorrect un-balanced to
balanced cable.
2.– The mixer and the powered
speaker are not plugged into the
same mains outlet.
3.– The audio signal cable is too
long or too close to an AC cable.
4 - DASnet ecP_xx cable is
defective.
5 - Error in DASnet Patch panel 485
net connection.
1.– The audio signal cable is too
long or too close to the lighting
cable.
2.– In a sound system with three-
phase AC, the lighting equipment
and the UNIT are connected to the
same phase.
1.– Bad or loose AC connection to
the UNIT or the mains outlet.
2 – Faulty AC cable.
3 - Internal fuse blown
SOLUTION
1 – Check that the mixer or sound
source is sending signal to the UNIT.
2 – Check that the cable from the
sound source to the UNIT is
connected correctly. Replace the
cable if defective.
1 - If using a mixer, use the
balanced output if available. Use a
professional mixer with a hotter
output.
2 - Try to cool the unit turning down
the master of the mixer.
1 - Turn mixer channel gains down.
Check that none of your signal
sources are distorting.
1 - Turn down the mixer's output.
1.– Read the appendix of this
manual to make a correct un-
balanced to balanced cable.
2.– Connect the mixer and the unit
to the same mains outlet.
3.– Use a cable that is as short as
possible and/or move the audio
signal cable away from the mains
cables.
4 - Check that there aren´t pins
crossed in CAT7 cable. Possible
short between audio par and
DASnet signal.
5 - Make sure that Audio INPUT is
not connected in DASnet INPUT and
vice versa.
1.– Move the audio signal cable
away from lighting cables. Try to find
out at what point the noise is leaking
into the system.
2.– Connect the sound system to a
different phase than the lights. You
may need the help of an electrician.
1.– Check your connections.
2.– Check the cables, connectors
and AC power with a suitable mains
tester.
3 - Replace the fuse for another of
the same size and type.
