INSTALLATION CONSIDERATIONS RECOMMENDED AMPLIFIER POWER For satisfactory performance, we recommend using a surround amplifi er with a power rating of 10 to 150 watts. Curiously, most loudspeakers are not damaged by large amplifi ers, but rather by small amplifi ers. If your system is playing loud music, a small amplifi er will run out of power very quickly and can create damaging “clipping” distortions. A more powerful amplifi er will play at the same volume without distorting. See OPERATION o

LOUDSPEAKER PLACEMENT NOTE: THE NILES HDLCRBX LOUDSPEAKER IS DESIGNED FOR USE IN FRONT LEFT-, CENTER-, OR FRONT RIGHT-CHANNEL APPLICATIONS ONLY. FOR BEST RESULTS, PLACE THE HDLCRBX ON A STAND OR BOOKSHELF. FOR REAR-CHANNEL APPLICATIONS, WE RECOMMEND USING A NILES HDFX OR CM750FX LOUDSPEAKER. PLACING HDLCRBX’S AS THE FRONT LEFT AND RIGHT LOUDSPEAKERS In a home theater, the intelligibility of dialog and action reproduced by the front loudspeakers is para- mount!

As for placement height, place front left and right loudspeakers vertically on either side of the picture source, so that their tweeters are not more than 24 inches above or below the center- channel loudspeaker’s tweeter (see Figure 2 on page 6). For best response, orient the loudspeakers so the tweeters face out. NOTE: DO NOT PLACE AN HDLCRBX LOUDSPEAKER TOO CLOSE TO A DIRECT-VIEW TV MONITOR, AS IT MAY CAUSE PICTURE DISCOLORATION. TEST THE PLACEMENT DISTANCE FOR PICTURE DEGRADATION BEFORE

ACOUSTIC FINE TUNING Each HDLCRbx loudspeaker features separate Treble Cut and Dialog Enhance controls on the rear for acoustic fi ne-tuning after placement, as shown in Figure 4. Adjust these controls as follows: • Initially set Treble Cut to Flat and Dialog Enhance to Normal. • If a HDLCRbx is placed in a room with highly reflective surfaces like glass or tile or the reproduced sound is too bright, set the Treble Cut switch to – 3 dB to lower the high- frequency response. • Listen

Of course, there are some wires that appear completely identical. So be careful, or you might make a connection mistake. If you do, one loudspeaker will be playing “out-of-phase” with the other loudspeaker. A pair of out-of-phase loudspeakers works against each other, and the sound of the two playing together will be lacking in bass and sound “phasey.” If you suspect the sound is not right, and you cannot see any markings on the wire, try this simple test: 1. Stand halfway between the lo

OPERATION LISTENING AT HIGHER VOLUMES Achieving a reasonable volume of sound in a large room requires more amplifi er power than it does in a small room. It is possible to turn the volume up so high that the amplifi er runs out of power. This creates “clipping” distortion, which will make treble sound very harsh and unmusical. When you hear harsh-sounding treble from any good loudspeaker, turn the volume down immedi- ately! Those harsh sounds are masking much more powerful ultra-high-frequency
