ACOUSTIC FINE TUNING The HDLCRbx includes acoustic fine-tuning controls on the rear panel. These controls enable optimiza- tion of the high frequencies and dialog with 3 dB of Treble Cut and 3 dB of Dialog Enhancement. ® D.S.F.G. DIRECTED SOUND FIELD GEOMETRY DEFEAT The HDLCRbx includes a rear-panel control that enables the installer to deactivate the D.S.F.G. ® Directed Sound Field Geometry in certain applications. For example, when the loudspeaker is installed at ear level behind a perfora

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

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 CM6HDFX 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.

FINISHING THE INSTALLATION CONNECTING THE LOUDSPEAKER 1. At eac h loudspeaker, separate the loudspeaker wire so that at least 2 inches of each conductor are free. Strip away 1/4 inch of insulation from each loudspeaker wire. Using correct polarity, connect the appropriate conductor to each five-way binding post. NOTE: Observe correct polarity: Positive (+) goes to the RED post and negative (–) goes to the BLACK post. If you are unsure of wire polarity, see the section, Checking Louds

ACOUSTIC FINE TUNING Each HDLCRbx loudspeaker features separate Treble Cut and Dialog Enhance controls on the rear for acoustic fine-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 t

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 amplifier power than it does in a small room. It is possible to turn the volume up so high that the amplifier 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 s
