THE HOME THEATRE ENVIRONMENT
Front and Effects Channels
The front loudspeakers are placed on either side of the television screen, 2 to 3 metres
apart. The speakers should be angled slightly so they are aimed towards the listeners.
As the rear surround channels are the ‘effects’ channels the reproduced sound should be as
room filling as possible. We recommend placing the speakers in a high position, behind the
listeners head. If the rear wall is more than 1 metre behind the listening seat, position the
units on the side walls. If the walls are a long way from the listening seat, consider stand
mounting the loudspeakers.
Most of the dialogue comes from the centre loudspeaker. Speech should appear to originate
from the actors mouths. Operating height is important. Ideally the front and centre channel
speakers should be at the same height. For this reason the centre channel speaker is best
operated above the television monitor.
Subwoofer
As the ear is unable to detect the direction from which deep bass origi-
nates, this allows you freedom to position a subwoofer according to the
level of bass required. Placing the subwoofer near a corner or particu-
larly close to a wall will boost the bass but may impair clarity.
The performance of Home Theatre systems can often be enhanced by
using a pair of subwoofers.
Evo²-DFS Surround Loudspeaker
As the rear effects channels are restricted in both frequency and dynamic range, there
is no particular advantage to be gained from bi-wiring. The DFS loudspeaker has a
single set of connection terminals as shown in the diagram.
Four self adhesive spacers are provided with each unit. Attach one close to each rear
corner of the cabinet. This speaker is designed primarily for wall mounting – please
see separate section for this topic.
Evo²-Centre Loudspeaker
A set of self adhesive pads is provided. Peel off the backing material and fix a
pad close to each corner of the bottom surface of the loudspeaker.
The Evo²-Centre Loudspeaker
The loudspeaker should be positioned centrally between the loudspeakers close to the televi-
sion 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 televi-
sion, 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 be
regarded as a second best. The preferred position is always above the monitor.
The Evo²-DFS Loudspeaker
Connect the cable to the speaker. The speaker should ideally be sited 600mm – 1.5 metres
above the listening position and 2.5 - 3.5 metres apart, central to the listener and behind
the listening position, preferably on a rear wall. If the listening position is some distance from
a rear wall, the loudspeakers may be mounted on opposite side walls but always behind the
listening position.
Ensure that the wall is strong and can support the product. Drill two 5mm holes in the wall
160mm apart and horizontally aligned. Fix a suitable No 8 round head screw firmly into
each hole using appropriate wall plugs. Leave a stub of 5mm protruding from the wall. Align
the holes in the mounting brackets over the screw heads and carefully lower the unit onto
the screws. The speaker can now be securely attached with the spacers resting against the
wall. Now connect the speakers to the amplifier before final mounting of the surrounds.
