CAS 3.1 AND CAS 2.
TECHNOLOGY CAS Series loudspeakers incorporate several innovative technologies that, when combined with many hours of subjective listening evaluations and our rigorous engineering standards, result in a loudspeaker that realistically and accurately reproduces the signal source with minimal distortion and coloration.

Unpacking the Product Finish unpacking the speakers and check the contents. If you suspect damage from transit, report it immediately to your dealer. Keep the shipping carton and packing materials for future use. Included CAS 3.1 MOUNTING MOUNTING FRAME FRAME CAS 2.
PLACEMENT FIGURE 1 ➢ ➢ LEFT LEFT CHANNEL CHANNEL RIGHT CHANNEL The Infinity CAS in-wall speakers are designed to offer excellent performance in any listening room or home theater system. 2-Channel or Front Left and Front Right in a Home Theater System Ideally, the speakers should be placed at least three feet away from the side walls. In 2-channel applications, the two speakers should be equidistant from your primary listening position.
INSTALLATION The CAS Series of in-wall speakers were designed to be easily installed. However, if you are unsure of your ability to properly install these loudspeakers, please contact your dealer or a qualified installer. Step 2 Note that the CAS 3.1 and CAS 2.1 speakers come with the baffle assembly attached to the mounting frame at its four corners to prevent damage during shipping. Unscrew the four screws as shown and carefully lift the baffle assembly out of the mounting frame. Note that the CAS 3.
Step 4 The CAS mounting frame has a series of spring-loaded clamps around its perimeter.These are designed to fold shut as you push the mounting frame into the hole and spring open once inside, thus holding the mounting frame in the wall. Insert the mounting frame into the cutout, making sure that you run the speaker wire in through the rear opening. Starting from the lower right-hand corner and working in a counterclockwise fashion, hand-tighten each of the 12 clamp screws (ONLY until almost snug).
Step 5 Place the supplied fiberglass insulation in the rear of the mounting frame. Place the cardboard shim on top of the lower front ledge of the frame, as shown.The cardboard shim is for aligning the baffle assembly properly within the speaker mounting frame. Lift the speaker baffle up and place it on the shim. Connect the speaker wires as shown on pages 9 and 10 and slide the baffle into place.
Step 6 Insert the four rubber grommets that retain the grille posts into the screw hole on the front, as shown.The grille has two side clips that look like wings.These extend about 1/4." See illustration. Note the side flange areas that catch the clips. Make sure these side clips are extended before attaching or removing the grille. Extend the side clips and attach the grille, reclipping it once in place.These side clips push inward to lock the grille onto the speaker.

BI-WIRING The CAS speaker’s connection panel and internal dividing network are designed so that separate sets of speaker cables can be attached to the low-frequency transducer and midrange/high-frequency transducer portions of this dividing network. This is called bi-wiring. Bi-wiring can provide several sonic advantages and considerably more flexibility in power amplifier selection. 1. Remove strapping wires. 2.
INSTALLER INFORMATION Enclosures The internal volume of an enclosure is directly related to the amount of low-frequency extension and output that can be accurately reproduced by a loudspeaker.The CAS in-wall loudspeakers were designed to use the typical wall cavity dimensions of 8' x 14-1/2" x 3-1/2" for maximum low-frequency extension. However, due to varying construction standards, materials and applications, it is sometimes beneficial to create a dedicated enclosure for the speakers.
