The appliance may cause distortion of cathode ray tube images beyond this distance.

Introduction

Thank you for purchasing a B&W ASW 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. Adding the subwoofer to your system not only extends the bass to lower frequencies, it improves the midrange clarity by reducing the low-frequency demands on your existing speakers.

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 Accessory pack containing:

4 Rubber feet
4 Spike feet
4 Lock nuts

1 International warranty document

Positioning the subwoofer

Because the subwoofer produces only low-frequency sounds, positioning is less critical in some respects compared to full-range speakers. Directional information is much less precise and you have more choice where to place the speakers to good effect. This said, best results are obtained if the subwoofer is placed between the satellite speakers or in the vicinity of one of them. If you use two subwoofer, it is best to put one near each satellite speaker.

Placing the subwoofer behind the listeners, even in surround sound installations, generally gives inferior imaging, but may be an acceptable compromise if domestic considerations dictate.

As with all speakers, the proximity of room boundaries affects the sound. Bass is generally increased as more surfaces come into close proximity with the speakers. Unlike full-range speakers, however, you can always restore the correct overall system balance by adjusting the volume level of the subwoofer. The more boost you get from the room, the less hard the speaker has to work; but there is a down side. Corner positions often excite more low-frequency room resonances, making the bass more uneven with frequency. There is no substitute for experiment as all rooms behave differently, so try the subwoofer in a variety of positions before making a final decision. A piece of music with a bass line ascending or descending the musical scale is useful for assessing the smoothness of the bass response. Listen for exaggerated or quiet notes. Having a separate subwoofer does enable you to optimise for room resonances independently from sitting the satellite speakers for best imaging.

If the subwoofer is to be used in a confined space (eg in custom furniture), the space must be ventilated to allow sufficient air to circulate and cool the unit. Ask your dealer for advice.

The subwoofer is supplied with four spike feet. The spikes pierce through carpet pile, giving a firm support directly to the floor surface without crushing the pile.

If the unit is to be placed on a vulnerable surface, such as a wooden floor, either place a protective disc under each spike or fit the four rubber feet in place of the spikes.

When fitting either the rubber feet or the spike feet, first screw the lock nuts fully onto the thread and then screw the feet fully onto the threaded inserts in the base of the cabinet. If the unit rocks, loosen the relevant two opposing feet until the support is firm, then re-tighten the lock nuts to the inserts.

Check that there are no cables under the carpet that may be damaged by the spike feet.

Do not walk the product on the spike feet as this may cause them to become detached from the cabinet and cause damage.

Take care not to impale yourself with the spike feet when moving the product.

Electrical connections

Disconnect all sound system equipment from the power supply until the signal connections have been made and checked. This avoids the risk of damage whilst connections are made or broken.

The function of the subwoofer is to receive signals from the amplification chain and, where necessary for 2-channel audio, split the signal into low bass and higher frequencies and feed the latter back out to the satellite speakers. Left and right channel inputs may be combined into a single mono low bass feed to the subwoofer drive unit if required.

The subwoofer will input and output line-level signals via the RCA Phono sockets located on the back panel.

Use the following table to select the correct wiring method for your installation:

Application: Home Theatre

The subwoofer may be used with any decoder that has a line-level subwoofer output (normally from an RCA Phono socket). Most decoders with integral power amplifiers still output the subwoofer or Low-Frequency Effects (LFE) signal at line level.

• Decoder with one or more subwoofoers - fig. 3

Application: 2-channel audio

Separate pre- & power amplifiers:

a One or more subwoofoers with output combined into a single mono signal - fig. 4
b Two subwooers with separate left and right signal - 5

The subwoofer is not suitable for use with 2-channel integrated pre/power amplifiers.

Using more than one subwoofer

Using more than one unit in a single installation can improve performance in the following ways:

• Maintain stereo separation to the lowest frequencies.
  Cope with larger listening rooms.
• Enable greater maximum sound output – often useful for effectively reproducing special effects in Home Theatre applications.
• Smooth out the effects of low-frequency room resonances.

If you are using two subwooers for 2-channel audio, separation is improved if each channel has its own subwoofer, providing each one is placed close to the relevant satellite speaker. Only use the mono connection of figure 4 if you cannot place each subwoofer close to its satellite speaker.

Double-check the connections

Before auditioning the sound quality of your new installation and fine-tuning it, double-check the connections. All too often, users complain that they cannot get a decent sound however they set the controls, only

to discover something has been wrongly connected. Make sure that:

• The phasing is correct - there should be no positive to negative connections to the satellite speakers. If something is out of phase you may get a fuzzy sound with an imprecise and floating image, a lack of bass or a combination of the two.
  There are no left to right mix-ups - this can result, for example, in the orchestra being the wrong way round or, more disastrously, sounds on your Home Theatre going in the opposite direction to the action on the screen.

Switching on and off

We recommend that you switch the subwoofer on before any power amplifiers receiving signals from the subwoofer. Similarly, when switching off, switch the subwoofer off last.

The MODE standby/auto/on switch (4) does not isolate the amplifier completely from the power supply. It maintains a low-power input to an auxiliary sensing circuit.

The switch (4) operates as follows:

On:

With the switch in this position, the amplifier remains permanently on, and the light (1) glows green.

Auto:

On first switching the subwoofer to Auto, the amplifier becomes fully active and the light (1) glows green. After a period of about 5 minutes without an input signal, the amplifier automatically reverts to standby mode, and the light glows red. When an input signal is detected, the amplifier automatically becomes fully active and the light glows green.

Standby:

In this position, the amplifier is in permanent standby, and the light glows red.

If the subwoofer is to be out of use for an extended period of time, we recommend you isolate it from the power supply, either by using the POWER switch (13) or by removing the plug from the power socket.

Setting the controls

There are 5 controls to consider:

The VOLUME control (2)
- The LOW-PASS FREQUENCY control (3)
The PHASE switch (7)
The LOW-PASS FILTER switch (6)
The EQ (equalisation) switch (5)

The optimum settings depend on the other equipment used with the subwoofer. If using more than one subwoofer, ensure the controls on each one are set the same.

Use with home theatre decoders

The B&W ASW Active Subwoofer is not a THX® licensed component, but may be used with a THX® controller if desired.

• Set the VOLUME control initially to the half way (12 o'clock) position.
• The setting of the LOW-PASS FREQUENCY control is irrelevant.
• Set the PHASE switch initially to 0^ .
• Set the LOW-PASS FILTER switch to OUT.
• Set the EQ switch initially to position A.

See also the section "Fine tuning".

If you have a THX® controller, ensure that the subwoofer function is enabled. When so configured it incorporates all the filtering 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 decoders, configure 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 decoder to set the levels of all the speakers. Only change the VOLUME control on the subwoofer if there is not enough range in the decoder to achieve the correct levels.

Inexpensive sound level meters are readily available from electronics stores and should be used to calibrate the levels. Refer to your decoder manual for further details on how to set the levels.

Use for 2-channel audio

• Set the VOLUME control initially to the half way (12 o'clock) position.
• Set the LOW-PASS FREQUENCY initially to 80Hz.
• Set the LOW-PASS FILTER switch to IN.
• Set the EQ switch initially to position A.
• Set the PHASE switch initially to 0^ .

See also the section "Fine tuning".

Fine-tuning

There are two settings of the EQ switch. Position B is optimised to allow the subwoofer to provide the highest listening levels, while position A gives greater bass extension coupled with a tighter sound.

2-channel audio

The optimum settings of the PHASE switch and the LOW-PASS FREQUENCY control are inter-related and also dependent on the low-frequency cut-off characteristic of the satellite speakers and the relative positions of all the speakers in the installation.

Set the system up in the preferred position and play some programme with a steady bass content. The optimum setting for the LOW-PASS FREQUENCY depends on several variables; the bass performance and power handling of the satellite speakers, the number of subwoofoers used and their position relative to the satellite speakers. The range 80 - 90Hz is a good starting point for the LOW-PASS frequency.

Unless two subwoofoers are used to preserve separate right and left channel information and are sited close to the relevant satellite speakers, using a higher cut-off frequency may compromise the stereo image and should only be considered if the bass performance of the satellite speakers is particularly limited.

At each setting of the cut-off frequency, listen with the phase switch in both positions. The correct one is that which gives the fullest bass and that will depend on the bass characteristics of your satellite speakers and the relative distances of the subwoofer(s) and the satellite speakers to the listeners. When using more than one subwoofer, ensure that each one has its cut-off frequency and phase switch set the same way.

Set the loudness of the subwoofer relative to the satellite systems to your liking. Use a wide variety of programme material to get an average setting. One that sounds impressive on one piece may sound overpowering on another. Listen at realistic levels as the perception of balance varies with sound level.

Home theatre

The situation with home theatre is somewhat different from 2-channel audio. The subwoofer (LFE) signal is a separate channel rather than an extension of the signal to the satellite speakers. The LOW-PASS filter is switched out, because the decoder provides all the filtering for any speakers set to "small". 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 significantly different from the other speakers, or the power amplifier 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^ .

Decoders 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

If you get problems with lumpy bass - if certain bass notes are exaggerated more than others - then you probably have a room interface problem and it is worth experimenting with the placement of the subwoofer. What may seem like small changes in position - 15cm (6in) or so - can have a profound effect on the sound. Try raising the subwoofer clear of the floor as well as lateral movement. The use of multiple subwoofer can smooth the effects of room resonances, as each subwoofer will tend to excite resonances at different

frequencies. If you alter the relative distances from the subwoofer(s) and satellite speakers to the listeners appreciably, reassess the phase switch setting. You should also check the level setting of the subwoofer (using either the decoder output levels or the volume control on the subwoofer amplifier as appropriate), but only after setting the phase correctly.

Taking care of the subwoofer

The cabinet of the subwoofer may be cleaned by dusting with a dry cloth. If you wish to use an aerosol cleaning spray, do not spray directly on the cabinet; spray onto the cloth. Remove the grille first so that the cloth does not become stained, but be careful not to disturb the drive unit. The grille itself may be cleaned using a soft brush.

Do not use the subwoofer as a table. When in use, objects left on top of the subwoofer are liable to rattle. In particular, avoid the risk of liquids being spilled (eg from drinks or vases of flowers).

If the system is taken out of use for a long period, disconnect the subwoofer from the power supply.

Note: The subwoofer will automatically shut down if driven excessively. If this occurs, re-set the subwoofer by turning it off then on again, using the power on/off switch on the amplifier panel.
