[. . . ] If desired, spikes can be added to the bottom of the cabinet to create the proper tilt angle. Refer to the "Adjustable Spikes" section for additional information. C52 (Center) Figure 6: On Top of Monitor C52 (Center) STAND MOUNTED Set the Placement Compensation switch to Stand Mounted if the C52 loudspeaker is placed on a stand as shown in Figure 7 (bottom-right). An optional pedestal stand is available at authorized Revel dealers. Rear Projection Screen or Large Direct-View Monitor Front Left Front Right CAUTION Loudspeakers placed on stands or video monitors may fall if tipped or improperly positioned. To avoid this, anchor the loudspeaker and stand using the same procedures and hardware used to anchor bookcases, wall units, and other furniture. Harman Specialty Group assumes no responsibility for proper selection and installation of hardware or for any personal injuries or product damages resulting from improper installation or a fallen loudspeaker. Figure 7: Stand Mounted Front or Large Rear Projection Screen Optional Pedestal Stand Front Left C52 (Center) Front Right REVEL Performa C52 OWNER'S MANUAL 11 ADJUSTABLE SPIKES When the C52 is shipped, spikes are attached to the left pad identified in Figure 2. For optimal sound quality, the spikes can be positioned in the threaded inserts on the bottom of the cabinet. Both 1. 5-inch (38mm) and 2. 25-inch (57mm) adjustable spikes are included, allowing for achievement of the proper tilt angle when the C52 is placed on top of a video monitor as shown in Figure 6 or a shelf. For best results, the C52 should be tilted so the front of the speaker is facing directly toward the listener's ears. Select the appropriate set of spikes to create a tilt angle that aligns the tweeter with the listener's ears. · Select the 1. 5-inch spikes for a slight downward tilt as shown on the left side of Figure 8 (below). Select the 2. 25-inch spikes for a greater tilt as shown on the right side of Figure 8 (below). Make sure the two spikes are evenly threaded to achieve a level balance. Place the protective caps over the round end of the spikes as shown on the right side of Figure 9 (next page) to prevent the spikes from scratching the mounting surface. When both spikes have been inserted, stand the C52 in the upright position. If needed, adjust the spikes to achieve a level balance. · 3. These inserts are identified on the left side of Figure 9 (next page). Rotate the first spike clockwise, spike end first, to attach it to the threaded insert.

Failure to do so may cause damage to some power amplifiers. 8 9 10 11 12 13 14 15 Before making connections, note the following: · Use high-quality loudspeaker cable with a maximum total loop resistance of 0. 07 or less (for each wire run). Refer to the table in the next column to determine the appropriate maximum wire gauge. 16 17 18 Note High loop resistances that exceed 0. 07 (for each wire run) will cause the filter network to mis-terminate, resulting in considerable degradation of sound quality. REVEL Performa C52 OWNER'S MANUAL 13 Making Connections · (continued) SINGLE-WIRED CONNECTIONS Single-wired connections are the most common. These are made between one pair of C52 input terminals and one power amplifier output channel as shown in Figure 10 (below). Connect one pair of loudspeaker wires to the desired pair of C52 input terminals. Connect the same pair of loudspeaker wires to the desired power amplifier output channel. Make all connections observing the proper polarity, positive-to-positive (+) and negative-to-negative (­). [. . . ] However, all loudspeakers have limits when it comes to continuous playback. To extend these limits, avoid playback at volume levels that distort or strain sound. CAUTION To avoid damage, reduce volume level immediately if loudspeaker sound is not clean and clear. Note · Refer to step 2 on the previous page for information about C52 crossover requirements. · If desired, contact an authorized Revel dealer for information about the suitability of power amplifier components before connecting the C52 to the associated power amplifier.

Conservatively-rated specifications indicate moderate sensitivity, meaning that a massive power amplifier is not required to drive Revel loudspeakers to reasonable volume levels in large listening spaces.
