Introduction
Thank you for purchasing a B&W Active
Subwoofer.
Since its foundation in 1966, the continuing
philosophy of B&W has been the quest for
perfect sound reproduction. Inspired by the
company’s founder, the late John Bowers,
this quest has entailed not only high
investment in audio technology and
innovation but also an abiding appreciation
of music and the demands of film sound to
ensure that the technology is put to
maximum effect.
This subwoofer has been designed for
Home Theatre installations and to augment
the bass performance of full-range
speakers in 2-channel audio use.
Please read through this manual fully before
using the subwoofer. All sound installations
require some planning and experimentation
if you are to get the best out of the
products used and this manual will guide
you in this process.
As the subwoofer is connected to the
electricity power supply, it is important that
you familiarise yourself with the safety
instructions and heed all warnings.
Keep this manual in a safe place for future
reference.
B&W products are distributed to over
60 countries worldwide and we maintain an
international network of carefully chosen
and dedicated distributors. If you have a
problem, which your dealer cannot resolve,
our distributors will be more than willing to
assist you.
Unpacking
(figure 1)
The easiest way to unpack the subwoofer
and avoid damage is as follows:
Open the carton flaps right back and
invert the carton and contents.
Lift the carton away from the product.
We recommend that you retain the
packaging for future use.
In addition to this manual, the carton
should contain:
1 Subwoofer
1 Signal lead
1 Mains lead
Note:
230V models may contain 2 mains leads,
one with a plug having two round pins and
the other having three rectangular pins.
Warning:
Do not attempt to use a mains
lead having a plug
inappropriate to the outlet
sockets of the mains supply.
Inputs, controls and indicators
Important safety information
For aesthetic reasons the
rating label of this device is
affixed to the underside, in a
position where it is not visible
in normal use. For this reason,
facsimiles of four variations of the
information label are reproduced in figure 2.
There may be small variations to the
markings in some markets, but the power
supply voltage rating and fuse rating will
always be shown in one of these formats.
Only use the product if the marked voltage
rating matches that of the power supply.
Do not replace the fuse with any other type
than that marked.
