Bowers & Wilkins 800 D3 [8/86] Fine tuning

ENGLISH

There are two pairs of terminals at the back of each

speaker that enable bi-wiring (top left). For single wire

connection, t the supplied link wires to join the like

polarity terminals together. Bi-wiring can improve the

resolution of low-level detail.

Ensure that the positive terminals on the speaker (with

red ring) are connected to the positive output terminal

on the amplier and the negative terminals on the

speaker (with black ring) are always connected to the

negative output terminal on the amplier. Incorrect

connection will not result in damage but will cause poor

stereo imaging and loss of bass. Always screw the

terminal caps down fully to prevent rattles.

Before ne tuning, make sure that all the connections

in the installation are correct and secure.

Moving the speakers further from the walls will

generally reduce the volume of bass. Space behind the

speakers will also help to create an aural impression of

depth. Conversely, moving the speakers closer to the

walls will increase the volume of bass.

If the bass seems uneven with frequency this will most

probably be due to resonance modes in the listening

room. Even small changes in the position of the

speakers or the listening position can have a profound

effect on how these resonances affect the sound.

Try moving the listening position or locating the

speakers along a different wall. The presence and

position of large pieces of furniture can also inuence

resonance modes.

If the central image lacks focus, try moving the

speakers closer together or angling them inward

so that they point at a location just in front of the

listening position.

If the sound is too bright, increasing the amount of

soft furnishing in the room (heavier curtains for

example) may help balance the sound. Conversely,

reducing the amount of soft furnishing may help

brighten a dull sound.

For the most discerning listening, remove the bass/

midrange grilles by gripping around their edges and

gently pulling them away from the cabinet.
