INTRODUCTION With its striking and sophisticated appearance, the Revel Ultima VOICE center-channel speaker hints at its advanced design from the first glance. The simple, clean lines characterize an exceptional sound reproduction system defined by custom-designed drivers, individually optimized crossover network, and a highly-functional enclosure. We created the VOICE speaker to achieve superior performance in the widest possible range of multi-channel environments.

DESCRIPTION The Ultima VOICE center-channel speaker uses two 8-inch mica and carbon-filled copolymer woofers to reproduce the lower octaves. A 4-inch titanium transducer reproduces the very important midrange frequencies. A 1-inch textile-dome tweeter reproduces higher frequencies.

• Oversized 2-inch diameter voice coil with flat aluminum wire offer higher power handling than average-sized coils for greater accuracy at high volume levels and during extended crescendos. TWEETERS Each VOICE speaker also contains a high-performance tweeter with the following features: • Optimized tweeter-dome profiles for maximum dispersion, while eliminating coloration caused by “break-up modes.

PLACEMENT Sound quality is heavily dependent on the accuracy of all your speakers, their placement in the listening room, and the acoustics of the room itself. Since the VOICE center-channel speaker is extremely accurate, experiment with the following speaker systems and placements (Figures 3 through 5) to enhance performance. NOTE: The VOICE center-channel speaker includes a user-adjustable placement compensation circuit that tailors the response for a desired application (e.g.

SPEAKER CONNECTIONS The VOICE center-channel speaker can be connected to your audio system in three different ways: single-wired, bi-wired or bi-amplified. Please read the following three sections before proceeding with the actual connections. Also, be sure to observe the following points: • Use high-quality speaker cable (maximum total loop resistance of 0.1 ohms per channel) with high-quality connectors between the speaker and your audio system.

BI-WIRED SYSTEM CONNECTIONS A bi-wired system involves two pairs of speaker wires connected to a single amplifier channel. On the rear of the VOICE speaker, remove the shorting straps and connect the + and − of one pair of wires to the HIGH FREQUENCY INPUT terminals and the + and − of the other pair of wires to the LOW FREQUENCY INPUT terminals, as shown in Figure 7. Check with your Revel dealer for recommendations and possible benefits for your application. VOICE Rear Figure 7.

SPEAKER CONNECTIONS (CONTINUED) BI-AMPLIFIED SYSTEM CONNECTIONS You can connect the VOICE speaker in either a vertical or horizontal bi-amplified system without requiring an additional electronic crossover. VERTICAL BI-AMPLIFIED SYSTEM Using two identical amplifier channels, remove the shorting straps from the rear panel; then connect the VOICE speaker, as shown in Figure 8. CAUTION: Failure to remove the shorting straps when biamplifying may damage some amplifiers.
PAGE 11
HORIZONTAL BI-AMPLIFIED SYSTEM Using two amplifier channels, remove the shorting straps from the rear panel; then connect the VOICE speaker, as shown in Figure 9. CAUTION: Failure to remove the shorting straps when biamplifying may damage some amplifiers. Figure 9. How to connect the VOICE speaker in a horizontal bi-amplified system.

SYSTEM OPTIMIZATION 1. After connecting the VOICE speaker, initially set the HIGH FREQUENCY LEVEL control on the rear panel to the “0” position (see Figure 10). VOICE Rear Install straps for Revel Corporation Chatsworth, California Made in U.S.A. single-wired operation Note: Remove straps for bi-wired or bi-amplified operation On Top Of Monitor Flush Mounted Stand Mounted -.5 Install straps for 0 -1 +.

4. If desired, experiment with placement (see page 6) and try other PLACMENT COMPENSATION control settings to achieve the best overall tonal balance, image specificity, and spaciousness. There is no right or wrong placement or setting – only what sounds best. NOTE: Rotating the PLACEMENT COMPENSATION control to the right increases low-frequency output (see Figure 10). 5.

PANEL REPLACEMENT Although your new VOICE speaker is preassembled at the factory, you can replace existing panels with new ones as follows: 1. Place the speaker on a soft surface. Use the enclosed hex wrench to untighten panel bolts. Remove each panel and grille. 2. Install a new panel (see Figure 11). Start all four bolts (with trim rings) by hand and tighten them with the hex wrench. Be careful not to overtighten. Bolt Figure 11. Installing a new VOICE panel. Trim Ring 3.

4. Install the other panel, as shown in Figure 13. Carefully align panel cups onto grille tips. Start all four bolts (with trim rings) by hand and tighten them with the hex wrench. Be careful not to overtighten. Figure 13. Installing the other VOICE panel.

SPECIFICATIONS Revel utilizes proprietary measurement methods in the design and specification of our loudspeakers. Our research has developed a series of tests that represent a great leap forward in making measurements that dramatically contribute to our goal of accurately reproducing music or film. Sensitivity: 87 dB SPL, with 2.83 Vrms @ 1 m (4 pi anechoic) Sensitivity provides an indication of how much amplifier power is required for the loudspeaker to play at satisfactory volume levels.
PAGE 17
Frequency Responses: (continued) Listening Window Response; +1.5 dB from 100 Hz to 8 kHz This improved “on-axis” measurement reduces the visual confusion of inaudible local interference, yet still retains full accuracy without using “spectral smoothing” which results in significant data loss. Low Frequency Extension; -10 dB @ 43 Hz (-3 dB @ 67 Hz) Studies have shown that the -10 dB low frequency extension specification is the one that best correlates to controlled listening tests.
