position. The speakers should ideally be positioned so that the treble units are roughly at ear
level to a seated listener. As personal taste plays a large role, experiment with different
configurations and play a wide range of programmes before finalising the position of your
speakers.
Bi-Amplifying (Bi-Amping)
By connecting each loudspeaker drive unit to its own dedicated amplifier the advantages of Bi-
Wiring can be extended. If you own two identical stereo power amplifiers, your Crystal speakers
may be Bi-Amped. For further details please consult your dealer.
Centre Channel and Surround Connections
The XR CEN and rear surround loudspeakers are intended for use specifically with Audio Visual
equipment having Centre and Rear loudspeaker outputs. Connect these loudspeakers as shown,
again observing polarity. The speakers may be connected as shown, or bi-wired.
XR CEN Centre Loudspeaker
The loudspeaker should be positioned centrally between the loudspeakers close to the television
and mounted either above or below the screen.
The loudspeaker should be located on a stable flat surface to avoid any danger of the cabinet
moving when it is vibrated by high sound levels. If you mount the unit on top of the television,
move it forward so that the front grilles are level with or slightly in front of the screen. This will
reduce reflections from the screen and the top of the cabinet.
Although you can place the centre channel
loudspeaker under the TV monitor, this should
always be regarded as second best. The preferred
position is always above the monitor, as shown.
The XR CEN uses screened drive units and may
be placed close to a TV screen without ill-effects.
Conventional loudspeakers should not be
operated within 500mm of a TV screen as the
drive unit magnets may interfere with the picture
and cause colour distortion.

Caution-Connecting Wires
When connecting your loudspeakers, avoid
trailing cables across open floor spaces where
they can be a source of danger.
Route cables safely under carpets or along
room boundaries.
