ABOUT REVEL Since 1996, Revel has stood at the forefront of loudspeaker design and performance.

  • Page 6: About The Gem2

    Further, the expanded use of surround channels by film sound mixers has increased the importance of accurate timbre reproduction from surround loudspeakers. Listening to a multi-channel system utilizing Revel Ultima Gem2 loudspeakers as surround loudspeakers is truly a breathtaking experience.

  • Page 10: Filter Network

    FILTER NETWORK The Gem2 Loudspeakers utilize high-order networks which optimize both the on-axis and off-axis response. These sophisticated networks help to ensure smooth octave-to-octave balance and timbral accuracy. Separate woofer, midrange and tweeter filter boards prevent mutual interference between filter network components, dramatically reducing distortion over a wide dynamic range.

  • Page 12: Installation Considerations

    INSTALLATION CONSIDERATIONS Loudspeaker fidelity depends on the following three factors: 1. Loudspeaker accuracy 2. Loudspeaker placement 3. Listening room acoustics LOUDSPEAKER ACCURACY The advanced Ultima2 design features allow the Gem2 to achieve exceptional acoustical precision. Each Gem2 is hand-tuned during manufacturing to match the production reference standard within a fraction of a decibel, ensuring incomparable loudspeaker-to-loudspeaker consistency.

  • Page 13: Listening Room Acoustics

    The difference between superior and inferior results is often just a small adjustment of the primary listening position or loudspeaker placement. For more information or assistance contact an authorized Revel dealer.

  • Page 14: Owner's Manual

    ACOUSTIC TREATMENT MATERIALS As previously mentioned, the Gem2 Loudspeakers utilize high-order networks which optimize both the on-axis and axis response. Their optimized response minimizes sonic degradation that can occur in overly “live” rooms. Placing minimal acoustic treatment materials at primary reflection points will reduce these distortions even further.

  • Page 15: Making Connections

    The Gem2 is equipped with two pairs of input terminals to allow for bi-wiring or bi-amplification. While Revel does not endorse one particular connection method over another, these additional connection options are available if desired. The design of this loudspeaker is such that optimal performance can be attained using the standard connection method.
  • Page 16 • If desired, contact an authorized Revel dealer for information about the suitability of power amplifier components before connecting the Gem2 to the associated power amplifier. •...

  • Page 17: Single Wire Connections

    SINGLE WIRE CONNECTIONS Single-wired connections are the most common. These are made between one pair of the Gem2 input terminals and one power amplifier output channel as shown in Figure 6. To make single-wired connections: 1. Connect one pair of loudspeaker wires to the desired Gem2 input terminals.

  • Page 18: Bi-Wired Connections

    BI-WIRED CONNECTIONS Bi-wired connections are made between both pairs of the Gem2 input terminals and one power amplifier output channel as shown in Figure 7. To make bi-wired connections: 1. Remove the jumper straps identified in Figure 4, page 11. 2.

  • Page 19: Vertical Bi-Amplified Connections

    Vertical bi-amplified connections are made between both pairs of Gem2 input terminals and two separate power amplifier output channels. Each speaker is connected to its own power amplifier. The power amplifiers must be identical. Vertical bi-amplified connections are shown in Figure 8.

  • Page 20: Horizontal Bi-Amplified Connections

    However, these power amplifiers must have identical gain factors. If the gain factors are not identical, a means of adjusting the input level of at least one power amplifier is required. Contact an authorized Revel dealer for assistance. To make horizontal bi-amplified connections: 1.

  • Page 21: Optimizing Performance

    OPTIMIZING PERFORMANCE To optimize the Gem2 for best performance: 1. When the Gem2 is connected, begin with the Tweeter Level Switch set to 0. (Different listening rooms may require other High Frequency Level switch settings.) 2. Set the Low Frequency Compensation Switch to correspond with the Gem2 placement.

  • Page 22: Loudspeaker Volume Level

    LOUDSPEAKER VOLUME LEVEL High-order filters include steep cut-offs to reduce potential damage from “out-of-band” frequencies. Combined with carefully designed transducers and filter networks, this approach helps the Gem2 to maintain its performance under extreme operating conditions. However, all loudspeakers have limits when it comes to continuous playback.

  • Page 23: Specifications

    Conservatively rated specifications indicate high sensitivity, meaning that a massive power ampli- fier is not required to drive Revel loudspeakers to reasonable volume levels in large listening spaces. Indicates whether the loudspeaker presents a “difficult” or “easy” load on the associated power amplifier.
