MAXIMUM SPEAKER VOLUME
Due to their special design, speakers require special handling. All speakers should be run in before normal use. During the first 30 to 50 hours of
operation, the sound system should be used at maximum 50% capacity. During this time, avoid increasing the volume near the maximum power. It
is then that the factory rated characteristics and sound quality can be achieved. The maximum volume of a system is the one, at which the sound
produced is high quality and distortion free. Any further increase of the volume will not increase the output power, but raise the distortion which may
cause damage to the system.
THE AMPLIFIER
Use only an amplifier of the appropriate quality and power! At higher volumes, a low quality or low power amplifier may generate significant distortion,
which may impose harmful loads on the speakers. Using an amplifier with a power output higher than required may also overload an incompatible
speaker. Overloading may damage the speaker. This is a typical sign of improper use. Turn off the amplifier immediately if you notice a rubbing noise
or distorted sound, or if you detect a strange smell coming from the sound box. All speakers can be ruined by connecting to an inappropriate amplifier
or operating carelessly. The amplifier should have an output impedance between 4 and 8 Ohms.
PUTTING INTO USE
Make sure that the impedance and power specifications of the amplifier and the speaker are appropriate for their connection. The peak power of the speaker
should be at least 30 to 50% higher than the peak output power of the amplifier specified for each channel. Connect the wires to the speakers and amplifier
properly, especially observing the +/- polarity. During this time, make sure that the amplifier is disconnected. The red colour means positive polarity.
Some products may come with a free speaker wire so that one can try them. You can replace this with a professional version for better sound. We
recommend using pure copper or silver-plated copper speaker wires with a cross section of at least 2 x 0.75mm². The wires must be firmly tightened in
the terminal connectors. The bare ends of the wires must not touch each other.
Before switching on for the first time, check that the entire sound system for firm and short-circuit-free connections observing the correct polarity, and
that the volume control is in the minimum position. In order to avoid knocking of the speakers, do not make any cable connections on the amplifier or
speakers during operation. Never switch on (or off) the system at high volume settings. The sudden noise possibly occurring may immediately damage
your speakers. Note that the output power indicated on the amplifier is always meant with the equalizers turned off. When the equalizer is set to high
treble or bass response, the speaker load may be several times higher at the given frequencies.
MAGNETIC FRONT PANELS
The removable front panels contain magnets. These allow the protecting grid to be easily removed when cleaning or inspecting the speakers. To remove
the grid, hold it with one finger at the top two corners, and pull it. After replacement, perform positioning when the magnets already hold it. Do not touch
the speaker membrane!
PLACING THE SPEAKERS
They should be directed straight at the listener, and placed 30-50cm away from any wall or furniture. The sound boxes of the left and right audio channels
should be placed at least 1.5 to 2.5m apart from each other to achieve stereo surround sound. It is best practice to try different positions, and then determine
the final location of the speakers. Compare the differences in the bass (drums, bass…), middle (vocals, horns...) and treble (cymbals…) sounds.
If a microphone is connected to the amplifier, place it as far away from the sound box as possible to avoid feedback. Do not turn the speaker toward
the microphone, as feedback will damage the speakers. When using a microphone, increase the volume carefully and, if you notice any excitation,
immediately rewind the control and, if necessary, move the sound box to another position!
CLEANING
Use a soft, dry cleaning cloth. Avoid the use of any aggressive detergents and liquids. Do not let liquids get inside the unit or on its connectors.
MAINTENANCE
Periodically check the integrity of the speakers and wires. In case of a malfunction, immediately disconnect the appliance and contact a specialist.
TROUBLESHOOTING
If you detect any error, review the following checklist. This guide may help you identify the issue, provided that the appliance is connected properly.
Consult a specialist if necessary.
The speaker does not produce sound:
● The amplifier is not switched on.
- Check the status and functioning of the amplifier.
● The speaker is not connected to the amplifier properly.
- Check the connecting wires for correct polarity, possible breakage/short circuit and correct connection.
Inadequate volume or sound quality:
● The speaker is not connected to the amplifier properly.
- Check the connecting wires for correct polarity, possible breakage/short circuit and correct connection.
