LOUDSPEAKER PLACEMENT NOTE: THE STAGEFRONT LCR LOUDSPEAKERS ARE DESIGNED FOR USE IN FRONT LEFT, CENTER OR RIGHT-CHANNEL APPLICATIONS. FOR EFFECT CHANNEL NEEDS, WE RECOMMEND USING A STAGEFRONT FX LOUDSPEAKER. PLACING THE STAGEFRONT LCR AS THE FRONT LEFT AND RIGHT LOUDSPEAKERS In a home theater, the intelligibility of dialog and action reproduced by the front loudspeakers is paramount! The position of each loudspeaker plays a very important role in how clear the sound is and how a stereo imag

INSTALLATION CONSIDERATIONS (CONTINUED) As for placement height, place front left and right loudspeakers 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 3 on page 7). If the StageFront LCR loudspeaker is being installed in existing construction, please use the included cardboard template to mark your installation location. Check for proper clearance within studs or any other obstructio

FINISHING THE INSTALLATION CONNECTING & INSTALLING THE LOUDSPEAKER 1. Remove the magnetic grille by starting at a corner and gently pulling the grille outwards as you work around the edges. 2. At each loudspeaker, route the wire through the provided channel to the input connectors, then 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. 3. On each set of loudspeaker connectors, press down the sprin

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. 1. Install loudspeaker into wall. 2. Carefully peel adhesive-covering strips off of paint mask and align over magnets on loudsp

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 louds

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 immediately! Those harsh sounds are masking much more powerful ultra-high-frequency
