PLACING LOUDSPEAKERS FOR THE BEST SOUND QUALITY (CONTINUED) When using more than one pair, it is usually best to alternate a left channel and then a right channel, so that you have the best possible stereo coverage possible. The position of the loudspeakers and their surroundings play a very important role in how a stereo image is created.

INSTALLATION MOUNTING THE BRACKET (IF ATTACHING THE LOUDSPEAKER TO A WALL, CEILING, BEAM, OR OTHER SOLID STRUCTURE) 1. Loosen the bracket knobs and remove the bracket from the loudspeaker. 2. Hold the bracket up to the mounting surface. The loudspeaker can be mounted either horizontally or vertically.
3. If you have any connectors (gold pins or bananas) which you prefer to use, affix them to the stripped wire ends now. Only gold-plated connectors should be used outside, as they will not tarnish or corrode. NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 305-238-4373 Bottom of Speaker (CONTINUED ON NEXT PAGE)

CONNECTING THE LOUDSPEAKER 4. If using the bracket to attach to a solid surface, slide the loudspeaker onto the bracket. Do not tighten the knobs completely. Angle the loudspeaker so that the rear terminals are accessible. If using the shelf stand, position the loudspeaker on the stand and place it on the shelf or table where you want it.
Hosing off the loudspeaker is not recommended, as the tweeter is a precise mechanism which might be damaged by a high-pressure stream of water. NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 305-238-4373...
