center-channel speaker.

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, individual-

ly 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. Physically

small enough to be used in modest rooms, it is dynamic enough to

be used in very large rooms. It is equally at home in discriminating

multi-channel audiophile systems or home theater systems.

Moreover, we’ve taken the care to make it as adaptable as possible to

a variety of system placements and the acoustical interactions typi-

cally found in multi-channel systems.

ABOUT THE MANUAL AND WARRANTY

To begin enjoying your VOICE speaker, first read and then perform

the instructions in this owner’s manual. Maximum performance is

dependent on following all instructions described here, as well as

those found in the owner’s manuals of associated components in

your audio system. Save these instructions for future reference.

The Revel Ultima VOICE center-channel speaker is covered by a

limited 5-year warranty, so save the bill of sale to protect your pur-

chase and aid in any service-related questions.

and connection locations.

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 impor-

tant midrange frequencies. A 1-inch textile-dome tweeter repro-

duces higher frequencies.

Combined with an individually-optimized crossover network, this

transducer arrangement provides a uniform “listening window” or

area in which the sound varies little. Also, the large woofer size is

used to reproduce center channel information and all its dynamics

without compression.

MIDRANGE

To ensure accurate detail, each VOICE speaker has a 4-inch

midrange that is unique in the following ways:

• The midrange’s radiating surface is made of titanium for true

pistonic behavior throughout its operating range.

• The midrange’s motor system utilizes neodymium magnets with a

stray-flux containment system for shielding near video monitors.

• The cast magnesium frame provides optimum voice coil cooling

and minimum reflections, while offering excellent rigidity.

WOOFERS

To ensure uncompressed dynamic range, each VOICE speaker uses

a pair of 8-inch woofers that are unique in the following ways:

• The woofer’s radiating surface is made of an injection-molded

polymer material with incredible stiffness and internal damping.

• Optimized magnetic circuits to minimize harmonic distortion.

Connectors (with

• 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.”

• Linear reproduction with very-low harmonic distortion even at

high output levels for uncompressed sound purity.

• The tweeter utilizes a large voice-coil with an oversized surround

roll. This provides the higher power handling and longer excursion

capability required to reproduce greater uncompressed dynamics.

CROSSOVER NETWORK

Built into each VOICE speaker is an individually-optimized

crossover network with the following features:

• A 3-way, 24 dB per octave crossover at 300 Hz and 2.2 kHz

shapes the on- and off-axis response of each driver and the com-

plete system.

• Hand-wired filter networks with air-core inductors and film

capacitors are calibrated to match each Ultima VOICE speaker

to the reference standard.

• Provision for bi-amplified and bi-wired applications via remov-

able external shorting straps on the gold-plated binding posts.

• External level controls for the tweeter via calibrated switched

precision resistors, thus maintaining identical response from

both speakers for ideal imaging.

• External LF tilt control for speaker placement optimization.

CABINET

The cabinet offers groundbreaking appearance and aids in overall

system performance. The inner enclosure is designed as an acousti-

cally-inert platform for sound-wave generation. Integral top and

bottom panels provide a custom look via available finishes (see

Panel Replacement on page 14) and are internally damped by sand-

wiched viscoelastic energy-absorbing layers to reduce any sound

transmission effects.

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., stand mounting, flush mounting, or on top of moni-

tor). See “System Optimization” on page 12 for detailed use on the

PLACEMENT COMPENSATION control.

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. Consult your Revel dealer as

to specific recommendations for your application.

• Turn off all audio system power before making any connections.

• Read the owner’s manuals that were included with your audio

components to confirm their connection procedures.

• Verify correct polarities (i.e., + to + and - to -) when making

connections. Failure to do so will cause poor imaging and

diminished bass response.

• For bi-wired or bi-amplified applications, remove the shorting

straps on the rear of the VOICE speaker (refer to Figures 7, 8,

and 9 on the next three pages).

SINGLE-WIRED SYSTEM CONNECTIONS

For most applications, simply leave the shorting straps in place and

connect the +and −from a single amplifier channel to the HIGH

FREQUENCY INPUT terminals on the rear of the speaker, as

shown in Figure 6.

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 termi-

nals, as shown in Figure 7. Check with your Revel dealer for recom-

mendations and possible benefits for your application.

(CONTINUED)

BI-AMPLIFIED SYSTEM CONNECTIONS

You can connect the VOICE speaker in either a vertical or hori-

zontal bi-amplified system without requiring an additional elec-

tronic 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 bi-

amplifying may damage some amplifiers.

NOTE: When using two dissimilar amplifiers, connect the VOICE

speaker in a horizontal bi-amplified system (see the next section).
