Russound Contractor Series manual Speaker Wire Paths, Corners and Reflections, Installation

Corners and Reflections:

When a ceiling speaker is placed close to the corner of a room, bass fre- quencies are emphasized. This is fine if both speakers are mounted near corners (while maintaining stereo imaging), but try to avoid placing just one speaker in a corner and another on a long flat surface. In general, the best acoustic performance will result if both speakers face a similar type of surface and are placed in similar positions on the same type of wall or ceiling.

Russound ceiling-mount speakers may be used for rear surround sound channels by placing them (1) behind, (2) on each side of the viewing position or (3) in the ceiling just behind the viewers. The available SP-C550 and SP-C650 speakers also make excellent, unobtrusive front channel home theater speakers for 5-channel listening (4,5).

Optimally, Russound wall-mount speakers should be located with the tweeters at ear level when the listener is seated.

Installation:

When installing the speakers, avoid:

•T-bar “drop ceilings” with very thin fiberboard panels which can buzz and vibrate. If you suspect this will happen, reinforce the drop-in panel with wood or particle board.

•Any wall which can’t provide proper depth (clearance) for the back of the Russound speaker. This includes brick or concrete walls where the wallboard or paneling is attached to thin furring strips.

•Inside wall space less than 10” wide and 24” in height

•Ceilings and walls where you know that there are pipes, heating ducts and ESPECIALLY AC wiring in the general vicinity. For example, if there is an outlet along the baseboard, there is often a live wire running partly up the wall at that point. The same applies for ceiling fans, overhead lighting, etc.

SPEAKER WIRE PATHS

In general, you should pay particular attention to the following areas:

•Avoid running speaker wires close to house electrical wiring for any distance. If you have to run them parallel, make sure to space the speaker wires at least two feet from the AC line. It is permissible for speaker wires to cross paths with AC lines or go through the same hole together with house wiring if they separate before and after.

•Make sure that the entire path between speakers and amplifier is clear and not obstructed by a floor or ceiling joist or masonry wall which you won’t be able to drill through.

•Remember that the other end of the wires has to come out some- where to connect with the amplifier. Confirm ahead of time that you can drill an outlet hole easily and in an unobtrusive spot.
