First of all, congratulations on your purchase of an active subwoofer from
quadral. It is with discerning music lovers and connoisseurs like yourself in
mind that we build hi-fi and surround speakers to standards way beyond
the norm. On the following pages we would like to give you some useful tips
on setting up, connecting up and operating your quadral active subwoofer to
ensure many hours of pure listening pleasure.
Safety notes on active loudspeakers
Please read these user instructions carefully and follow all recommended steps towards putting
your system into operation. You should at all times be aware of and take note of the warnings
and safety instructions on the device and in these user instructions. Keep these user instruc-
tions in a safe place so you can find them straight away if you should have any queries or
problems at a later date.
Your set has been drafted for the usage at 115 V~ 60 Hz or 230 V~ 50 Hz mains supply. Please
make sure before using the system, that the corresponding working voltage for your country has been
adjusted on the back of the set (by delivery it is 230 V~ 50 Hz).
Lay the mains cable and other cables in such a way that they cannot be stepped upon, or crushed
or damaged by spikes or furniture, or cause anyone to trip over them. The mains plug shall remain
readily operable.
When removing the mains cable from the wall socket, do so by pulling the plug out and not by tug-
ging the cable itself.
Unplug the mains cable in the event of storms or if you are not going to be using the system for a
longer period of time.
The loudspeaker connection terminals (High Level Input) may only be used in conjunction with the
corresponding amplifier outputs or satellite speakers. Connection of any kind between these terminals
and the mains supply (230V/115V) is prohibited and will lead directly to the immediate destruction of
the loudspeaker and all connected products. For this reason it is essential to avoid fitting these cable
connections with plugs which could in any way whatsoever be confused with mains plugs.
At high volumes and depending on the connected power amplifier, voltages of over 30V can be
present at the loudspeaker connection terminals marked High Level Input. These terminals should
therefore on no account be touched while the system is active.
Our subwoofers are desigend for use in normal living roomes and moderate climates only and should
never be set up and operated in damp rooms or tropical climates. They never get in touch with drip-
ping or splashing water. Furtheron no objects filled with liquids, such as vases, should be placed on
the sets.
Massive overloading of loudspeakers due to excessively high volume levels can, under certain
circumstances, lead to the fusing of individual elements or speakers in spite of safeguards. Theoreti-
cally, overloading to this extent can even cause fire inside a loudspeaker, so it is advisable to keep
loudspeakers under surveillance when being operated at such outer technical limits.
Faulty safeguarding, if accessible from outside, has to be replaced only by equal types.
The temperature of the rear heat sink can rise to over 60°C when the unit is used over a longer period
of time at high volumes, so please at all times avoid touching it when it is active.
