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.
SPEAKERS	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.
	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
AV	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
POSITIONING	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.

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-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.

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.
