INTRODUCTION: WHAT IS A HIGH END IN-WALL? The new Snell AMC series units bring a novel approach to the design and construction of in-wall loudspeakers, expanding the boundaries of in-wall performance. Our primary goal was to develop loudspeakers that delivered performance that was as close as possible to that of our highly regarded freestanding loudspeakers, like the K.5 mk2 and E.5 mk2. To do this, several issues had to be addressed. The bass performance of conventional loudspeakers mounted in

PLACEMENT OF THE FRONT CHANNEL SPEAKERS A home theatre system includes three loudspeakers placed across the front of the listening room. The distance between the left and right speakers determines the width of the stereo image. If the speakers are placed too close together, the image will be too narrow; too far apart and the blend will suffer, creating a hole in the middle. When properly placed, your speakers will create a continuous “virtual image” from left to right, with an illusion of sound

If two surrounds are used in a standard 5.1 configuration (not 7.1 or EX), they are best mounted to the sides of the listening area. This means straight to the sides of the listener or in line with the primary row of seating, plus or minus 15 degrees. This is preferred over back wall mounting for several reasons: It places the surrounds at locations where the difference between left ear and right ear discrimination is at a maximum. This gives the maximum sense of “envelopment” or being surrounde

AIMING THE DPT (AMC720, AMC 760 and AMC800 only) In addition to providing an extremely clean wide range response, the DPT have the added feature of an adjustable waveguide (in 45 degree increments). This unique Snell feature provides the opportunity to toe-in conventionally mounted in-wall systems or compensate for the less than ideal placements that occur in the real world. This feature will greatly improve imaging. To adjust the DPT rotation, remove the four wood screws with a 5/64” allen driv

Setting the Dispersion Switch The illustrations below show the recommended Dispersion Switch setting for most common placement options for the AMC 800. Horizontal Placement Vertical Placement *Note: When the AMC 800 is used as a center channel speaker and is placed horizontally, the dispersion switch may be set in either position. INSTALLATION INSTRUCTIONS IMPORTANT: This manual assumes that the installer possesses skill in the proper use of hand and power tools, knowledge of local building and

PREPARING FOR INSTALLATION Map out the wiring paths from the speakers to the amplifier. We recommend 16-gauge wire for runs up to 25 feet, and 14-gauge wire for longer runs. Be sure the speaker wire does not rest or rub against any sharp or pointed objects. The speakers should be mounted on a flat surface to form a good seal between the speaker flange and the mounting surface. When connecting more than two speakers per amplifier channel, you should use series/parallel wiring. In all cases, make

5) Place the speaker into the rough opening. 6) Level the speaker and tighten the screws, being careful not to over tighten them. See diagram below for details. Turn the mounting clamps against the enclosure, then place the speaker in the mounting hole. Use a phillips head screwdriver to deploy the mounting clamps and pull them against the back of the drywall. 7) Replace the speaker grille. Note: The AMC 900 is sold in pairs. On the cabinet, near the input terminals, is a temporary THX label to
