Niles Audio CM5HD, CM6HD, CM8HD instruction

Final Installation in New or Existing Construction

1.If it is possible to lay a batt of insulation into the ceiling cavity do so. Remember to use equal amounts of insulation for each speaker.

2.Check the position of the Impedance Jumper on the crossover PC board. Choose the 4 ohm position if you are using an amplifier capable of drawing a 4 ohm load and you have only one pair of speakers connected. Otherwise, use the 8 ohm position (See Figure 15).

3.Separate the speaker wire so that at least two inches of each conductor are free.

4.Open the no-strip terminal by applying pressure to the red and black levers until an audible “click” is heard.

5.Insert one unstripped wire fully into the black and one into the red terminal. Pay attention to the markings on the wire. Each speaker must be connected to the amplifier in the same way. If unsure, see “Speaker Phase” located on the fol- lowing page. Squeeze the red and black levers until they click signifying that they have locked into the wire. Check to make sure that the knife assembly inside the no strip connector has prop- erly pierced the wire (See Figure 16).

6.Insert the no strip terminal into the corresponding socket on the rear of the speaker. Push it down until it locks in place. The terminal will only fit in the socket in one direction. If the ter- minal does not properly seat, reverse the terminal

7.On both models, there are four clamps or mounting “dogs” which hold each speaker in place. The dogs are tight- ened via four front-baffle screws. To install the speaker, first rotate the dogs inward. Insert the speaker into the cutout and tighten the dogs by turning the screws clockwise. DO NOT OVER- TIGHTEN THESE SCREWS. Over-tight- ening the clamps may make the grille difficult to install. (See Figure 17).

NOTE: The screws will be easier to turn if you “prime” them first. Before installing each speaker, turn the screws in and then turn them back out to their original positions.

8.Direct the Tweeter. The tweeter is directed by gently pushing on the edge of the tweeter grille. It will move 20° in any direction. For critical listening point the tweeter to the user’s favorite listen- ing position minimizing reflections from the side walls. For surround sound or low volume background listening cre- ate more reflections and thus more ambience by directing the tweeter towards the side walls. See Speaker Placement on Page 6.
