Connecting Your Loudspeakers

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 Pacific Evolution speakers may 
be Bi-Amped. For further details please consult your dealer

Choose a suitable length of twin core speaker cable for each channel, and prepare the ends as described

The Pacific Evolution Centre and DFS Surround loudspeakers are intended for use specifically with

Repeat this procedure for the Right Channel. 

You may connect the loudspeakers using either the upper or the lower pair of terminals.

Positioning Your Loudspeakers

If the loudspeakers are placed too close to the walls the bass will increase but may be boomy and

Pacific Evolution 20, 30 and 40 are designed to be floor standing. We suggest you position them at 

increased by up to 40%, although this may restrict the width of the optimum listening position. The 

least 200 mm from the rear walls and 700 mm from the side walls, facing slightly inwards. The Pacific 

speakers should ideally be positioned so that the treble units are roughly at ear level to a seated 

Evolution 8 and 10 should ideally be stand or wall mounted though they may be placed on a rigid  

listener. As personal taste plays a large role, experiment with different configurations and play a wide 

shelf. The bass extension will improve if these speakers are operated closer to the rear walls. A useful 

range of programmes before finalising the position of your speakers.

rule of thumb is that the listener should be as far from the loudspeakers as they are from each other. 

Pacific Evolution Centre Loudspeaker 

This 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.
