Introduction Thank you for choosing a Blueprint Series In-Wall Loudspeaker ® from Niles. With proper installation and operation, you'll enjoy years of trouble-free use. The HD or High Definition group of Blueprint Series In-Wall Loudspeakers® offers speakers expressly designed for superior sonic quality. They employ advanced technology components designed to extract the subtle nuances in recorded music or the thunderous action in a movie.
BumpBack™ Woofer Magnet(s) Niles engineers have utilized a unique magnet construction allowing far greater “throw” or voice coil excursion. This allows a new level of deep bass performance to be achieved. X-Matrix™ Reinforced Baffle The X-Matrix Baffle design uses specially molded ribs to add rigidity to the baffle assembly. The end result is better bass and improved midrange detail.
Incorporating a Remote Control If you are planning to use a stereo system with a hand held IR remote control, consider the advantages of installing a Niles IR Repeater system. You are able to control all of the functions of your system from the room with the remote pair of speakers. Niles makes a number of IR sensors which install in the wall, in the ceiling, in cabinetry, on tabletops, or even behind the grille of your Niles HD speakers.
The Boundary Effect Corners can affect the bass response of the speaker powerfully! This is called the boundary effect. You will emphasize particular bass frequencies and cancel out other bass frequencies when you place speakers close to the wall/ceiling boundary or a corner wall boundary. This can make the speaker sound excessively boomy and inaccurate to some listeners, while to others it just seems like more bass sound.
Of course, the best way to emulate the sound of multiple speakers is to use multiple speakers. In large or unusually shaped rooms this might be the only way to achieve a good effect. (See Figure 7). If you like to listen to music surround modes which emulate concert hall acoustics, more than two surround speakers will prove extraordinarily effective. With Niles HD•LRS loudspeakers it is easy to add another pair without affecting the decor of the room.
Pulling the Cable Pull the cable in sections (from the stereo to the volume control, from the volume control to the speaker). Start with the longest sections and use left-over wire to complete the short sections. If you plan to pull many rooms at the same time through a central route, walk off the distance to each destination, add a generous fudge factor for turns and other obstacles, then cut off each section so that you have a bundle of wires you can pull at once.
In traditional wood stud/drywall construction you can cut the hole for the speaker and utilize the large hole to auger holes across, up or down the wall for as far as your drill bit will take you. If you have matching paint and take reasonable care in patching you can cut a hatch in the drywall at each stud, run your wire, and patch and touch-up the wall (See Figure12).
Remove the grilles before painting. If you are using spray paint, use two thin coats without any primer. If you are using a compressor and a spray gun, use the finest, most diffuse setting. Practice first on some paper if you have no experience painting with spray paint. If you are using an applicator or brush, and a can of paint, thin the paint first. You do not want to have to poke hundreds of holes in your beautifully painted grilles.
4. If you are cutting into lath and plaster walls, use masking tape to outline your penciled marks, drill the four corners with a 1/4” bit and use a razor to score the plaster down to the lath beneath. Then use a chisel to remove all of the plaster within the taped outline. Finally, insert a metal cutting blade into a sabre saw and very slowly and carefully saw the lath. Sawing the lath can easily vibrate plaster off the wall.
Speaker Phase Speaker wire has two conductors. One conductor is attached to the negative (-) terminals and one conductor is attached to the positive (+) terminals of both your speaker and your amplifier. Usually, the wire is marked for your convenience. There are different ways wires are marked: a stripe on one wire, a ribbed area of one conductor you can only feel, different colors of metal wire on each conductor, or there might be a fabric strand or string wound into one of the conductors.
Limited Warranty Model HD•CTR Model HD•LRS Niles Audio Corporation ("NILES") warrants its loudspeaker products to the original purchaser to be free of manufacturing defects in material and workmanship for a period of two years from date of purchase.
