Set-up
When setting it up with other equipment, make sure that the appliance is
well ventilated. Keep a sufficient distance from heat sources. Do not place
the PA box directly next to heat sources, such as a heater. Do not point any
strong beams or light sources onto the device. This may lead to over-
heating (risk of fire).
The heat extraction of the device may not be obstructed. Do not cover the
backside of the device. The air circulation must not be obstructed by
objects such as magazines, tablecloths, curtains or similar. This prevents
heat extraction from the device and can lead to overheating (risk of fire).
Do not drill any additional holes or screw any additional screws into the
housing, since this could make contact to dangerous voltages possible.
Make sure that the connection cables are not being pinched or damaged by
sharp edges. Always lay the cables so that nobody can trip over or become
entangled in them. Risk of injury.
The cables must be sufficiently long. Avoid mechanical strain on the
cables. This may damage the cables or the device. There is a danger of fatal
electric shock.
Do not place the PA Box in the direct vicinity of screens such as TV sets or
computer monitors. The magnetic field of the speaker might distort the
image of such devices.
Only operate the PA box on a stable surface which is not sensitive to heat.
When setting up the device, make sure that it has a stable footing and that
the set-up place is correspondingly stable. Serious injury to persons can be
caused if the loudspeakers fall.
It is not permitted to suspend the PA box from the carrying handles or any
other fittings.
If the PA box is set up on a stand it has to be correspondingly robust and
suitable for the weight of the loudspeaker.
• Set up the PA box at the desired location.
• If necessary, a loudspeaker stand can be inserted in the loudspeaker flange at the speaker
bottom.
• Align the sound outlet as desired.
Connecting the signal input and output
When connecting the signal input and output, make sure that the
connection cable is not pinched or damaged by sharp edges.
The input may be connected only to low-level audio outputs of audio
devices.
The PA box and the device it is connected to must both be switched off dur-
ing connection.
Always use suitably shielded stereo or XLR cables for connecting inputs
and outputs. Using incorrect cables may lead to interference.
In order to prevent distortion and maladjustment which could lead to dam-
age to the PA box only connect audio devices with XLR-output or stereo
output.
Do not lay the connection cable in such a manner that it could be tripped
over.
• Connect LINE IN (5) to the preamplifier of the upstream audio device (e.g. mixer). The con-
nection LINE IN is equipped with a combined socket which allows the connection of stereo
and XLR plugs.
• Connect LINE OUT (6) with the input of another device that will receive the same signal as
the PA box.
Mains connection
The mains outlets which the PA box is connected to must be easily
accessible to quickly disconnect the device from the mains voltage in case
of an error.
The PA box and all connected devices must be turned off when connecting
the voltage supply.
Ensure that all the electrical connections and connection cables between
the different devices and any extension cables comply with the regulations
and comply with the operating instructions.
• Insert the non-heating appliance plug of the mains cable into the mains connection (8).
• Plug the power plug of the power supply cable into a wall socket.
• The POWER switch (7) is used to switch the PA box on and off.
Position „O“: Device is switched off.
Position „I“: Device is turned on.
• When the device is switched on, the POWER ON indicator (4) lights up.
Start up and use
Only put the appliance into operation when you have become familiar with
its features and these operating instructions. Check again that all
connections are correct.
Do not put the product into operation if it is damaged.
The PA box should always be the last to be turned on and the first to be
turned off. In this way you prevent any undesired noises, which can typi-
cally occur when switching off a mixer, from damaging the PA system.
The device may only be operated by persons familiar with the operating
instructions. Keep other persons and children away from the device.
• Turn the control LEVEL (1) back completely (to the left).
• Switch on the connected mixer and start the playback.
• Turn on the PA box with the POWER switch (17).
• The POWER (4) indicator is lit.
• As soon as the PA box detects a signal at the input the the SIGNAL OK indicator (3)
lights up.
• Adjust the volume on the mixer to about 75% of the maximum volume or to the maximum
undistorted level (visible on devices with recording level displays and the „0 dB“ marking).
• Adjust the volume of the PA box with the LEVEL control (1) to the maximum desired volume.
• This setting enables a high signal-to-noise ratio and gives the best audio quality.
• After this basic setting, the volume is set using only the volume control on the mixer. The set-
up procedure needs to be repeated with every change to the circuit.
• If the PA box switches off during volume peaks, it is overloaded. The PEAK/LIMIT indicator
(2) lights up and the built-in amplifier is switched off to prevent damage. Turn down the vol-
ume in this case. Switch the PA box on when the overloading no longer occurs.
• To switch the complete system off, first switch off the PA system with the POWER switch (7)
and then switch off the mixer.
Maintenance and care
The PA box does not require any maintenance.
It should only be vacuumed on the outside. Make sure not to touch the sensitive speaker mem-
branes.
Never use aggressive cleaning agents or chemical solutions as the carpet cover or the mem-
brane could be damaged.
Fuse replacement
If fuses have to be changed, make sure that they are replaced only with fuses of the same type
and rated current (refer to the „Technical data“).
You must not carry out your own repairs to fuses or bridge the fuse holder.
• Only after disconnecting from the mains (unplug at the socket) should be low-power main
connector be unplugged from the mains connection (8) on the device. Lever out the fuse
holder over the mains connection (8) with the defective fuse.
• Remove the defective fuse and replace it with a fuse of the same type.
• Now carefully put the fuse holder with the new fuse back in.
• Afterwards, reconnect the mains cable with the device and plug into a socket.
Disposal
Please dispose of the product, when it is no longer of use, according to the current
statutory requirements.
