Niles Audio CM760DS, CM750DS warranty Painting the Grille and Frame

IMPORTANT: OBSERVE CORRECT POLARITY: POSITIVE (+) GOES TO THE RED POST AND NEGATIVE (–) GOES TO THE BLACK POST.

8.Insert the loudspeaker module into the frame by carefully holding it with both hands and angling it slowly into the frame until the module is seated in the frame. Holding it in place, carefully use the same tabs used to remove it from the frame to turn it clockwise until you feel a ‘click’, which should be approximately an 1/8th of a turn. Take care not to push against the woofer or tweeter as you are inserting the loudspeaker module.

9.Direct the tweeter. The tweeter is directed by gently pressing on the outer edge of the tweeter housing. It will move up to 20 degrees in any direction and can be positioned independent of the woofer assembly. For critical listening, direct the tweeter towards the user’s favorite listening position. For surround sound or low volume background listening, create more refl ections and thus more ambiance by directing the tweeter towards the sidewalls. (See Figure 4)

10.Direct the woofer. The woofer assembly is directed by gently pressing on one or two points of the woofer housing using the edges of the tweeter bridge that are near the blue plastic visible at the outer edge of the woofer. It will move up to 20 degrees in any direction. For critical listening, direct the woofer assembly towards the user’s favorite listening position. For surround sound or low volume background listening, create more refl ections and thus more ambiance by directing the woofer towards the sidewalls. (See Figure 5)

11.Set the Treble level control. (CM750DS & CM760DS only) Listen to a well-recorded piece of music at the user’s favorite listening position. Listen for treble harshness or ringing, particularly when the loudspeakers are placed in a room without carpet. Use the -3dB Treble cut position to correct. Listen for dull or muffl ed upper frequencies, particularly when the loudspeakers are installed in an area with thick carpet or fabric wall coverings. Use the +3dB Treble boost position to correct. (See Figure 6)

12.Set the Presence level control. (CM760DS only) Listen to a well-recorded piece of music at the user’s favorite listening position. Listen for thin response in the upper bass frequencies, particularly when the loudspeaker is placed in the middle of a ceiling. Use the +3dB Presence boost position to correct. (See Figure 7)

13.Install the MicroPerf grille. Start by positioning one edge of the grille slightly inside the loudspeaker. Gently work around the loudspeaker a little at a time until the grille is fully seated. Don’t try to insert the grille fully in any one area, as this will make complete installation more diffi cult. Don’t force the grille to fi t as you may damage the grille if you apply too much force.

14.Connect the other end of each loudspeaker wire to the receiver (or amplifi er) carefully observing polarity.

15.Turn on the receiver or amplifi er and test all loudspeakers in the system.

PAINTING THE GRILLE AND FRAME

Each CM730DS, CM750DS & CM760DS loudspeaker frame and fl ush-mount metal grille may be painted without the need for primer. The frame may be painted prior to installation if desired.

1.Install loudspeaker frame into ceiling or wall following the previous steps 1 - 4.

2.Paint the frame of the loudspeaker.

3.Paint the grille separately from the loudspeaker frame. For best results when painting the grille, use a spray gun or airless sprayer. Thin the paint to prevent clogging of the grille holes and apply several light coats instead of one heavy one.

4.Finish installation of the loudspeaker following the previous steps 5-15.
