[. . . ] The Monopole mode is also suitable for 7. 1-channel configurations. 8 REVEL Concerta S12 Owner's Manual Surround Mode Configuration Control (continued) · Select the Monopole setting as shown in Figure 5 (right) to compensate for less than ideal speaker placement, such as if the speaker is mounted in a corner of the listening room. In Dipole mode, the driver pairs work out of phase to produce a "null" directly in front of the speaker, which results in a diffuse dispersion pattern, creating a large and enveloping soundfield. This mode is suitable for film soundtrack reproduction. Select the Dipole setting, as shown in Figure 6 (right) to lessen your ears' ability to locate the speaker to help create a sense of ambience. Figure 5: Monopole Mode Toggled to Monopole Monopole · Figure 6: Dipole Mode Toggled to Dipole Dipole See the Loudspeaker Placement/Mode Configuration section beginning on page 10 for more information. CABINET The trapezoidal shape of the cabinet contributes greatly to S12 performance because its design allows for the driver pairs to be at 72 degree angles to each other to create the varying dispersion modes. Cabinet-induced colorations are reduced with MDF walls. The cabinet vinyl finish does not require routine maintenance. However, cabinet surfaces that have been marked with fingerprints, dust, or other dirt can be cleaned using a soft cloth. The cabinet also includes an integral rear mounting system for direct wall placement. See the WallMounting Instructions section on page 15. CAUTION To prevent cabinet damage, do not use a cloth made with steel wool or use metal polish to clean the cabinet. Do not use any cleaning products or polishes on the cabinet or grille. Filter Network Optimizes loudspeaker on-axis and off-axis response with high-order filter at 2. 2kHz, helping to ensure smooth octave-to-octave balance and timbral accuracy. Gold-plated binding posts accommodate heavy speaker cables.

INPUT PANEL The numbers in Figure 7 (above) correspond with the numbered items in this section. 3. Mounting Keyholes For secure wall-mounting with wood screws. 1. Input Connectors Two "positive" and two "negative" gold-plated binding posts provide for connections from the associated power amplifier(s). Refer to the Making Connections section beginning on page 16 for additional information. LOUDSPEAKER PLACEMENT/MODE CONFIGURATION Loudspeaker fidelity depends on the following three factors: 1. Shorting-Straps Two gold-plated shorting-straps accomodate wired connections. · When using the S12(s) as the surround channels in a 5-, 6- or 7-channel home theater: · If using Bipole mode, the S12s should be placed behind the primary listening location, at an angle from 5 to 30 degrees behind the listening position, as shown in Figure 8 (right). Note Bipole mode provides a large ambient surround sound field while still allowing for precise localization of musical and special effects placed in the tracks. Set to Monopole to compensate for less than ideal placement, such as if the S12 is mounted in the corner of the listening room, or mounted less than three feet from the ceiling. REVEL Concerta S12 Owner's Manual 11 Loudspeaker Placement (continued) Note Note Monopole mode permits exact localization of sound effects because only one set of drivers (which should be angled toward the front of the room) are activated. Many listeners prefer this mode for high-resolution SACD and DVD Audio music recordings. · In Monopole mode, the S12s should ideally be placed from 20 to 30 degrees behind the primary listening position as shown in Figure 9 (below). In Monopole mode, if there are several rows of seating, place the speakers perpendicular to the middle row of seating. The set of drivers to the right of the Monopole setting indicator should be installed toward the front of the room as this is the system that will be activated, as shown in Figure 10 (below). An S12 used as a side channel mounted on the left wall (facing forward) must be mounted upright. Conversely, an S12 on the right wall would have to be inverted. [. . . ] Then, connect the same pair of loudspeaker wires to the desired power amplifier outputs. Note Set the Surround Mode Configuration control to Bipole for proper operation. Note In addition to the polarity symbols underneath the terminals, the binding posts also have red (positive) and black (negative) inserts to indicate polarity. Be sure to observe proper polarity, especially when inverting the right side speaker(s), to ensure proper connections. In Figures 18 and 19 the polarity of the input connectors are all labeled for clarity. CAUTION Failure to remove the shorting straps may damage the associated power amplifier. Figure 18: Dual-Speaker Mode Connection for a single S12 used as discrete rear channels S12 Left Rear Speaker Amplifier Right Rear Left Rear For Dual-Mode discrete rear channels, the S12 should be placed in the center of the rear wall. Right Rear Speaker REVEL Concerta S12 Owner's Manual 17 To make dual-speaker mode connections when a single S12 is used as discrete side and rear loudspeakers: 1. Remove the shorting-straps from both S12's input connectors. [. . . ]
