obstructed. If the system is taken out of use for a long period,
disconnect the subwoofer amplier from the mains power
supply.
Rack Mounting
The SA250 Mk2 is supplied with two rack mounting brackets
for installation in standard equipment racks (above). Attach
the brackets by inserting three of the short Philips head
machine screws through each bracket into the threaded
holes in the side of the amplier.
Rack Handles
Use of the handles is optional. Attach them by inserting two
long Phillips head screws through each bracket into the
threaded holes in the handles (above). If you do not use the

The Speakon® plug is shown disassembled in the gure
below.
In all cases, observe the correct polarity connections.
Incorrect connection will result in a poor imaging and/or a
loss of bass output.
Keep the total impedance of the speaker cable below the
maximum recommended in the speaker specication.
All audio connections should be made with the equipment
disconnected from mains power.
Connection to the subwoofer(s)
A single SA250 Mk2 can drive one or two identical
subwoofers in parallel. If you need more than two subwoofers
in the installation, or if you want separate left and right
channel subwoofers in a stereo installation, you will need
more than one amplier.
See the separate manual supplied with the subwoofer for
information on the location of the positive and negative input
terminals on the subwoofer itself.
Use either the binding post outputs (above) or the Neutrik®
Speakon® output (above right), wiring either one or two
subwoofers as required.

need a second SA250 Mk2. In this case, if the pre-amplier
allows, you can use balanced connections (above right).
Otherwise, use unbalanced connections (above left).
Connection to a stereo pre-amplier
You can combine both left and right channels into one or
two subwoofers using a single SA250 Mk2. In this case, only
unbalanced connection is possible (above).

Set the LOW-PASS FILTER switch (4) to Off.
The setting of the FREQUENCY (5) control is now irrelevant.
Set the BASS EXTENSION switch (6) initially to A.
Set the EQUALISATION switch (7) to Movies.
Set the PHASE switch (8) initially to 0.
Set the VOLUME control (9) initially to the 9 o’clock position.
See the Fine Tuning section for more.
The subwoofer and subwoofer amplier are not THX®
licensed components, but may be used with a THX®
controller if desired. If a THX® controller is used, ensure
that the subwoofer function is enabled. This incorporates
all the ltering and level setting required for the subwoofer
in all modes. For level calibration, the internal test noise and
channel level controls in the THX® controller should be used.
In all cases the levels should be set to obtain 75dB SPL
(C-weighted) at the listening position from the controller’s
internal noise test signal.
With other processors, congure the front and surround
speakers to “large” or “small” as appropriate before setting
the levels. Use the internal noise test signal and volume
controls of the processor to set the levels of all the speakers.
Only change the VOLUME control on the subwoofer amplier
if there is not enough range in the processor to achieve the
correct levels. Inexpensive sound level meters are readily
available from electronics stores and can be used to calibrate
the levels. Refer to your processor manual for further details
on how to set the levels.

Subwoofer Equalisation
Set the subwoofer switch (5) on the rear panel to the
appropriate model.
On the Front Panel
Switching On and Off
The subwoofer amplier is best switched on after any other
items and switched off rst. The Standby/Auto/On switch (3)
operates as follows:
Standby: The subwoofer amplier will become active when
12V is applied to its STANDBY TRIGGER input.
When 0V is applied to the trigger, the subwoofer
amplier will return to the Standby state. The
indicator will glow green when the subwoofer
amplier is active and red when the subwoofer
amplier is in Standby.
Auto: The subwoofer amplier will initially become fully
active and the indicator will glow green. After
about 5 minutes without an input signal, the
subwoofer amplier will automatically go to the
Standby state, when the indicator will glow red.
When an input signal is detected, the subwoofer
amplier will automatically become active and
the indicator will glow green. The subwoofer
amplier will return to Standby after about 5
minutes with no input signal. Some audio-visual
processors incorporating an automatic set up
procedure may be confused by a subwoofer
amplier with an auto On/Standby function and
a potentially damaging fault condition may arise.
The subwoofer amplier is best left switched on
and fully active during set up if such a processor
is used.
On: The subwoofer amplier will remain fully active
and the indicator will glow green.

2-channel Audio
Set the LOW-PASS FILTER switch (4) to On.
Set the FREQUENCY control (5) to match the -6dB low
frequency cut-off frequency of the satellite speakers.
Note: Both -3dB and -6dB gures can be found in the
specication of each Bowers & Wilkins speaker model. If the
satellite speaker manufacturer quotes only a -3dB frequency,
the optimum setting for the FREQUENCY control should be
between 0.6 and 0.9 times that gure. The more gradual the
low frequency roll-off of the satellite speakers, the lower the
frequency should be set.
Set the BASS EXTENSION switch (6) initially to position A.
Set the EQUALISATION switch (7) to Music.
Set the PHASE switch (8) initially to 180.
Set the VOLUME control (9) initially to the 9 o’clock position.
See the Fine Tuning section for more.
Before ne tuning, make sure that all the connections in the
installation are correct and secure.
Home Theatre
In home theatre systems, the subwoofer (LFE) signal is a
separate channel rather than an extension of the signal to
the satellite speakers. The subwoofer’s LOW-PASS FILTER
should be switched to Off because the processor provides
all necessary ltering. However, the position of the PHASE
switch must still be assessed. Normally the phase will be
set to 0, but if the subwoofer is positioned at a distance
signicantly different from the other speakers, or the power
amplier driving the other speakers happens to invert the
signal, the 180 position may be preferable. Listen with the
switch in both positions and choose the one that gives the
fullest sound. If there is little difference, leave the switch at 0.
Surround sound processors normally have a calibrated noise
signal that can be used to set the relative levels of all the
speakers, making the task somewhat more straightforward
than for 2-channel audio. However, do not be afraid to alter
the settings to your personal preference. It is all too easy
to get carried away with the capabilities of the subwoofer,
especially with some special low-frequency effects. Often a
more realistic portrayal, and one more satisfying in the long
term, is to be had by setting the subwoofer level lower than
the standard calibration level.

All Applications
The BASS EXTENSION switch offers three options of
subwoofer bass extension. Position A gives the greatest
extension and position C gives the least extension. Position
B provides a compromise setting. If the system is to be
used at very high volume levels or in a large listening room,
restricting the bass extension by selecting either B or C may
help ensure that the subwoofer is not asked to exceed its
performance limits. In most situations the BASS EXTENSION
switch should be left in position A.
The EQUALISATION switch alters the subwoofer bass roll-off
alignment appropriate to Movies or Music listening. The
Movies position gives a “drier” alignment, more suited to the
demands of action movie low frequency effects. The Music
position is suited to a faster more accurate bass line.
The 3.5mm EQUALISATION input on the back panel is
designed to receive a 12V signal that will toggle the Movies/
Music setting at the front panel. Set appropriately, the 12V
trigger output of a processor can automate ideal performance
of the subwoofer.
To use this feature, set the front panel EQUALISATION switch
to Movies. When 12V is applied to the trigger input, the EQ
will change it to Music. When 0V is applied to the trigger
input, the EQ reverts to Movies. Care must be taken in setup
of the processor in order to take advantage of this feature.
2-channel Audio
Set the system up in the preferred position and play some
material with a steady bass content.
The optimum settings of the PHASE switch and the
FREQUENCY control are inter-related and also dependent
on the low-frequency cut-off characteristic of the satellite
speakers. However, the settings recommended above for the
FREQUENCY control and PHASE switch have been chosen
to integrate well with most satellite speaker bass alignments.
Using the initial settings, rst check the setting of the PHASE
switch. Choose the option that gives the fullest sound.
Normally the recommended option will be optimum, but
may not be in certain circumstances. These may be that
the power ampliers feeding the satellite speakers invert
the signal or that the subwoofer is not placed close to the
satellite speakers.
Next, adjust the VOLUME of the subwoofer amplier relative
to the satellite systems to your liking. Use a wide variety of
programme material to get an average setting. A setting that
sounds impressive on one piece may sound overpowering on
another. Listen at a realistic volume level as the perception of
musical balance varies with sound level.
Finally, adjust the FREQUENCY control to give the smoothest
transition between the subwoofer and satellite speakers.
