Connecting Your Loudspeakers -Bi-Wiring

Using separate cables for treble and bass units in a Bi-Wiring configuration reduces intermodulation effects and improves headroom and clarity. To bi-wire, you will need to install two lengths of twin core cable between the amplifier and each loudspeaker.

Unscrew each terminal a few turns and remove the metal straps. Connect the cables between the amplifier and the loudspeakers as indicated above and re-tighten all the terminals securely.

Note: Some amplifiers have two pairs of output terminals to facilitate bi-wiring but this is not essential. The advantages of bi-wiring are fully retained if your amplifier has only one pair of output terminals per channel (as in the illustration).

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.

Positioning Your Loudspeakers

Conventional Loudspeakers

Models XR 3500, XR 4000 and XR 5000 are designed to be floor standing. We suggest that they are positioned at least 200mmfrom the rear walls and 700mmfrom the side walls, facing slightly inwards. Models XR 1000, XR 2000 and XR 3000 should ideally be stand or wall mounted though they may be placed on a rigid shelf. The bass extension will improve if these speakers are operated closer to the rear walls. A useful rule of thumb is that the listener should be as far from the loudspeakers as they are from each other.

If the loudspeakers are placed too close to the walls the bass will increase but may be boomy and indistinct. If the loudspeakers are placed further away from the walls, the inward angle may be increased by up to 40%, although this may restrict the width of the optimum listening 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.

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.
