  • Page 6: Description

    DESCRIPTION The Revel Performa B15a powered subwoofer system features a unique transducer that combines brute-force capabilities unprece- dented in home loudspeakers with a new level of low frequency nuance and refinement. Combined with the huge internal power capability, the result is a new standard of superb bass performance and adaptability for home entertainment systems.

  • Page 7: Electronics

    ELECTRONICS Each Revel Performa B15a contains an electronics section with the following attributes: • An extremely low-distortion, 1,000-watt (rms) amplifier with 1,400-watt burst capability produces peak bass output up to 126dB at 30Hz in an average-sized listening room. • Inaudible protection circuit to guard against thermal overload.

  • Page 8: Unpacking

    Refer to the Obtaining Service section on page 26 for additional information. 1. Set the packaged Revel Performa B15a subwoofer on a soft towel or carpeted surface in the upright position. Open the top flaps as shown in Step 1 of Figure 3 (below). Set aside the power cord and other items located on the top pad.

  • Page 11: Placement

    PLACEMENT Due to the long wavelengths being reproduced, low-frequency bass response from the Revel Performa B15a subwoofer is non-direction- al. However, optimum results can be obtained by making in-room measurements to determine the best locations for all of the speakers in your specific listening room (see System Optimization on page 21).

    AUX OUTPUT: Use stereo XLR (balanced) connectors or RCA (unbalanced) jacks to loop input audio signals to additional REVEL PERFORMA B15as (if present). Both outputs are 0 dBv (nominal)/+20 dBv (maximum). The XLR input is pin 2 high. HIGH PASS OUTPUT: Use stereo XLR (balanced) connectors or RCA (unbalanced) jacks for (high-pass) connection to the main amplifier’s inputs.

    Also, be sure to observe the following: • 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. REVEL PERFORMA B15a Owner’s Manual...

  • Page 18: Multi-Channel Controller Without High-Pass Crossover

    If the B15a subwoofer will be used without a high-pass crossover (see Figure 13), contact your Revel dealer for help in setting the crossover controls so the main speakers and the B15a subwoofer(s) will produce an optimum combined response.

    #1 B15a to #3 B15a AUX OUTPUT INPUT REVEL PERFORMA B15a SUBWOOFERS IN MULTIPLE OPERATION Multiple B15a subwoofers (using their own crossovers) can be connected in a “daisy-chain” with a multi-channel controller and power amplifier, as shown in Figure 14. If all subwoofers are placed next to each other or in symmetrical room locations, set all level and phase controls for the same respective values.

    CONNECTIONS (Continued) REVEL PERFORMA B15a SUBWOOFERS AND STEREO BASS Two B15a subwoofers can be interconnected with a preamplifier and power amplifier for stereo bass (see Figure 15). NOTE: Although stereo bass requires symmetrical placement, asym- metrical placement also has advantages (see “Placement” on page 11).

    -octave measurements have inade- quate resolution, often resulting in misleading data and degraded sound quality. Simply use the REVEL LFO test signals disc and the LOW FREQUENCY OPTIMIZER will plot the results of the measurement at each speaker or listener (microphone) location.

Other sound measurement systems may also be used to help determine speaker and listener locations, as long as the selected 1 ⁄...
  • Page 23 Otherwise, select a location that is most desirable for aesthetic or other considerations. If the locations are to be determined by trial-and-error, begin with one Revel Performa B15a subwoofer in a front corner of the room (nearest the main loudspeakers).

  • Page 24: Troubleshooting

    TROUBLESHOOTING If the Revel Performa B15a subwoofer sounds distorted, stops play- ing, or otherwise seems to be malfunctioning, first determine whether the problem is in the subwoofer, the wiring, and/or other audio components. If the problem also affects the main speakers, the cause is most likely in your electronics.
