Speaker Installation
The CT8.4 LCRS speaker is intended for use in home
theatre front, centre and surround channel
applications. More specifically it can also be used as
the surround speaker option for the CT800 system
when space constraints prohibit the use of the
CT8 DS. The speaker can be wall mounted in either
vertical or horisontal orientation using the accessory
brackets.
To use the wall bracket attach its two shorter elements
to the speaker using the tapped holes in its back
panel and the four supplied M6 bolts. Attach the
longer bracket element to the wall in the appropriate
position. Once the two bracket elements are securely
attached the speaker can be hung on the wall. Figure
2 illustrates use of the wall bracket. Before using the
bracket ensure that the wall and fixings are capable of
supporting the weight of the speaker. B&W can accept
no liability for any failure of wall and/or fixings.
Regardless of the style of installation take care when
lifting the speaker into position. It is unwieldy and heavy
and best handled by two people working together.
A black fabric grille is attached via push-fit pegs.
Speaker Positioning
CT8.4 LCRS speakers used for the front channels in a
home theatre system should be positioned one either
side of the screen on the horizontal centre-line. They
should be within approximately 0.5m (20 in) of the
sides of the screen to help keep the sound image in
scale with the visual image. See Figure 1.
2
A CT8.4 LCRS speaker used for the centre channel in
a home theatre system should be positioned centrally
either directly above or below the screen. In the case
of acoustically transparent screens, the centre channel
speaker should be positioned centrally behind the
screen. See Figure 1.
CT8.4 LCRS speakers used for the surround channels
in a home theatre system should be positioned above
and to either side or behind the listening position. See
Figure 1.
Stray Magnetic Fields
The speaker drive units create stray magnetic fields
that extend beyond the boundaries of the cabinet. We
recommend you keep magnetically sensitive articles
(CRT television and computer screens, computer
discs, audio and video tapes, swipe cards and the
like) at least 0.5m (20 in) from the speaker. LCD and
plasma screens are not affected by magnetic fields.
Connections
All connections should be made with the equipment
switched off.
CT8.4 LCRS speakers have two pairs of binding post
connection terminals and one Neutrik
connection socket on their back panels. The binding
post terminals provide quick and easy connection of
stripped wires while Speakon
secure and reliable connection method. Both
Speakon ® and binding post terminal connection
methods provide the opportunity to bi-wire the
speakers.
To connect the speakers in conventional single-wire
mode using the Speakon
Speakon plug as shown in Figure 3a and connect the
®
positive cable to the terminals marked +1 and +2 and
the negative cable to the terminals marked -1 and -2.
Incorrect connection can result in poor imaging and
loss of bass. Once the plug is reassembled it can be
inserted into the socket and locked by twisting
clockwise.
To connect the speakers in conventional single-wire
mode using the binding post terminals, insert a short
length of stripped cable through the body of each
terminal and tighten the terminal head. Connect the
positive cable to one of the red terminals and the
negative cable to the corresponding black terminal as
illustrated in Figure 3b. Incorrect connection can result
in poor imaging and loss of bass.
To connect the speakers in bi-wire mode using
either the binding post terminals or the Speakon
socket
If the Speakon ® option is to be used, disassemble the
Speakon ® plug as shown in Figure 4a and connect
one pair of positive and negative cables to the
terminals marked +1 and -1 and the second pair of
positive and negative cables to the terminals marked
+2 and -2. Ensure that positive cables are connected
to the + terminals and the negative cables connected
to the – terminals. Incorrect connection can result in
poor imaging and loss of bass. Once the plug is
reassembled it can be inserted into the socket and
® Speakon
® sockets provide a more
