Refer to the “Limited Warranty” section found later in this manual for more information. HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 4 SUBWOOFER PLACEMENT To Unpack the B120: OM top-EPE subwoofer grille plastic bag bottom-EPE beauty carton Figure 1: Unpacking the B120 subwoofer 1. Place the packing carton upright and fully open the top flaps. Refer to Figure 1. 2. Without allowing the top flaps to close, stand the packing carton upside down by carefully “rolling” the carton over on a soft surface, such as carpet. 3. Lift the packing carton off of the subwoofer. Use caution to avoid damaging the cabinet and objects located above the packing carton. 4. In addition to what is shown in Figure 1 above, the following is included with each B120: 1 x 15' (4.6m) single-RCA LFE cable Below 300Hz, loudspeaker and listener locations have a profound impact on the way sound is reproduced. All rooms have “standing waves,” by which certain frequencies are emphasized or diminished. Their complex patterns can combine to introduce tremendous sound coloration at low frequencies. The Concerta B120’s Equalization controls can help to compensate for these effects, but no electronic system alone can fully compensate for the dramatic effects of room acoustics. Every room has locations where “nulls” at specific frequencies occur. These cancellations of the sound are like “black holes,” which no amount of equalization can fill. The best results are always achieved through careful placement of both the loudspeakers and the listening position. Preferable placement can be determined through the use of computer modeling programs, or by trial-and-error measurements. For optimal results, find the best loudspeaker and listener locations first, then use the B120 Equalization controls for fine-tune adjustments. To help determine good locations for the subwoofer(s) and the listener(s), it is recommended that you make high-resolution in-room response measurements. Your authorized Revel dealer can make the appropriate measurements, using suitable equipment to ensure optimal results. Note Many sound-measurement devices are not accurate enough to properly measure low-frequency performance in a listening room, since room boundaries can often cause modes (standing waves) with very narrow-band peaks and dips. Check with your authorized Revel dealer to confirm that your measurement equipment is suitable for accurate, high-resolution measurements. Revel Concerta B120 Owner’s Manual HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 5 GENERAL PLACEMENT GUIDELINES If using two B120 subwoofers but corner placement is not an option, try placing the subwoofers at the midpoints of opposite walls, as shown in Figures 4 and 4a. The following placement suggestions are followed by diagrams for recommended subwoofer locations. Due to the nature of room acoustics, the best approach is to experiment with different listening locations, as well as loudspeaker locations, to obtain the best sound at low frequencies. B120 Generally, it’s best to place the Revel Concerta B120 subwoofer(s) near solid walls to reinforce bass response. Avoid placing the subwoofer(s) near windows, which can rattle and transmit sound to the outside world. Placing a subwoofer in the corner of a room, as shown in Figure 2, results in maximum reinforcement, which contributes to lower distortion. Most dips cannot be equalized, but they can be minimized through the optimal placement of the subwoofer(s) and listening position. B120 B120 Figure 4: Two B120 subwoofers at opposite walls B120 B120 Figure 2: Single B120 subwoofer Placing two Revel Concerta B120 subwoofers in opposite corners of the listening room, as shown in Figure 3, results in smoother low-frequency response and more consistent sound throughout the listening area. Figure 4a: Two B120 subwoofers at opposite walls B120 Use of a modeling program or trial-and-error measurements to further determine the best locations is recommended. Using precise measurements to determine subwoofer placement minimizes the response dips due to standingwave cancellation that cannot be corrected by equalization. Ask your authorized Revel dealer for more information and assistance. B120 Figure 3: Two B120 subwoofers in opposite corners Revel Concerta B120 Owner’s Manual HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 6 For large rooms (greater than 2000 to 3000 cubic feet, or 57 to 85 cubic meters), consider adding one or more additional B120 subwoofers for greater bass output and lower distortion. Four properly placed Concerta B120 subwoofers achieve the smoothest low-frequency response with the most consistent sound throughout the listening area. When using four B120s, the flattest response is usually obtained by placing one pair at the midway point of the opposite front and back walls, and a second pair at the midway points of the side walls, as shown in Figure 5. Your authorized Revel dealer can use in-room measurements to fine-tune the locations, accounting for variation in construction among the room walls. A third alternative is to place the four B120s on the front and back walls at one-third of the distance into the room, as shown in Figure 7. B120 B120 B120 B120 B120 Figure 7: Four B120 subwoofers at the front and back B120 B120 B120 Figure 5: Four B120 subwoofers at midpoints Another option is to place four Concerta B120 subwoofers in the corners of the listening room, as shown in Figure 6. B120 B120 Figure 6: Four B120 subwoofers in the corners B120 B120 The placement of the other system loudspeakers in the listening room also affects the way sound (below 300Hz) is reproduced. Just as you would for the subwoofers, use a modeling program or trial-and-error measurements to determine the best locations. Since listening and speaker locations are equally important, the trial-and-error process can be time-consuming. However, the sonic rewards are well worth the time spent determining the ideal placement locations. Remember that peaks (below the subwoofer crossover frequency) can be minimized or eliminated by the proper adjustment of the Concerta B120’s Equalization controls, but dips cannot be corrected via equalization. Therefore, the most important objective is to find locations that result in the minimum number (and severity) of dips. Contact your authorized Revel dealer for assistance in determining the proper placement of your Revel loudspeakers and subwoofers. After placing the B120 subwoofer(s), begin playback of a familiar music or film source that has substantial bass content. Listen from the primary listening position, increasing the overall volume of the system to a comfortable level. Adjust the Subwoofer Level (volume) control until you obtain the desired blend of bass. Also, test the subwoofer level by playing a recording of a deep male voice. Setting the subwoofer level (or crossover frequency) too high results in unnaturally “thick” or “boomy” vocal reproduction. Bass response should not overpower the room, and should be adjusted to achieve a harmonious blend across the entire audible range. If you are using a multichannel receiver or processor with a subwoofer output, it’s preferable to use the Subwoofer Level adjustment on the processor. Set the B120 Level control to the indicated “Nominal” position. Revel Concerta B120 Owner’s Manual HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 7 Note Note Setting the level of the subwoofer in relation to the left and right front speakers is of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the level too high results in an overpowering bass response. Setting the level too low negates the benefits of the B120 subwoofer. Some processors incorrectly label the subwoofer output as LFE; others offer both an LFE and a Subwoofer output. If there is no labeled subwoofer output, use the LFE output. If the output has labeled connections for both LFE and Subwoofer, use the Subwoofer output. MAKING CONNECTIONS CAUTION! Never make or break connections unless all system components are powered off. The L (Left) and R (Right) connectors on the rear panel of the B120 are for use with 2-channel applications, where there is no dedicated subwoofer output available. These inputs are automatically crossed-over by the adjustable Low-Pass Crossover control on the rear panel. Having the low-pass filter enabled helps offset the fact that most 2-channel systems do not perform any high-pass filtering on the main speakers, minimizing the advantages of using a subwoofer. These connectors should be used in 2-channel applications where the receiver or preamplifier lacks a dedicated subwoofer or LFE output. Note The Concerta B120 subwoofer has a third connection option – wireless connection is also available when coupled with the optional TX1 transmitter. Refer to the “Wireless Connection” section found later in this manual for additional details regarding this option. Multichannel Applications – Typical Connection Figure 8: Rear-panel input connectors This section provides typical examples of cable connections with different system configurations and devices. Review the owner’s manuals for associated audio components to determine their connection requirements. The B120 subwoofer input connectors are located on the rear panel. Two gold-plated RCA connector options are available – Sub In Low-Pass Disabled (Normal) and L/R Low-Pass Enabled – as shown in Figure 8. In most cases, you’ll use the Sub In connector, as it’s designed for multichannel use. This input bypasses the low-pass filter, and is the appropriate input for most installations. This connector should be used when there is a dedicated subwoofer output available on the audio processor or receiver. Receiver/Processor Subwoofer Output B120 Input Panel Figure 9: Typical connection This configuration is for use with multichannel processors or receivers that have a single dedicated Subwoofer or LFE output connector. Connect the supplied RCA patch cable from the Subwoofer or LFE output on the processor/receiver to the Sub In connector on the B120 rear panel, as shown in Figure 9.

The internal low-pass filter in the B120 is used to limit frequency range of the subwoofer, preventing undesirable overlap with the main loudspeakers. 1. Connect an RCA patch cable between the left main output on the receiver/preamplifier to the L(eft) Low-Pass Enabled connector on the B120 rear panel, as shown in Figure 10. 2. Connect an RCA patch cable between the right main output on the receiver/preamplifier to the R(ight) Low-Pass Enabled connector on the B120 rear panel. Note This configuration applies to receivers with preamplifier outputs or to preamplifier/ power amplifier configurations in which there are two sets of Main outputs. If the receiver has jumpers from the Pre- or Main-Out to the Amp in connectors or if the preamplifier has only one set of Main-Out connectors, a Y-adapter should be used to send the same signal to both the main power amplifier and the subwoofer(s). Tape Out or Record Out connectors cannot be used. B120 Input Panel Sub 1 B120 Input Panel Sub 2 Figure 11: Connection to multiple B120 subwoofers This configuration is for use with multiple B120 subwoofers and a multichannel processor or receiver. Note The supplied single-RCA patch cord can be used in any of the three connections described below, but you will need to purchase an RCA Y-adapter and possibly an additional single-RCA cable. 1. Connect an RCA patch cable from the Subwoofer or LFE output on the processor/receiver to the single input on the Y-adapter, as shown in Figure 11. 2. Connect an RCA patch cable from one of the outputs of the Y-adapter to the Sub In connector on the first B120 rear panel. 3. Connect an RCA patch cable from the second output of the Y-adapter to the Sub In connector on the second B120 rear panel. Note Additional B120 subwoofers may be connected by using additional Y-adapters – by placing an additional Y-adapter input connector into one of the output connectors of the first Y-adapter.

The Input section of the rear panel was discussed in the “Making Connections” section, earlier in this manual. The subwoofer controls are discussed in this section. For more information on the wireless connection option, refer to the “Wireless Connection” section found later in this manual. Power Indicator LED The Power Indicator LED identifies the current state of the B120 subwoofer. The subwoofer has three different powered states – each identified by a different color. The Power Indicator LED reflects the color of the current power state. The color and the state each color indicates are: Red: Standby – the B120 automatically enters Standby if no signal is detected from the system for 10 minutes. Green: On – as soon as a signal is detected, the B120 powers on. Orange: On – the B120 is powered on, and both the wireless link and transmitter are active. 10 Revel Concerta B120 Owner’s Manual HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 11 Subwoofer Level (Volume) Control Provides basic volume adjustment for the subwoofer. Begin with this control set to the nominal “12 o’clock” position. Low-Pass Frequency Control 50Hz 150 H z Note This control does not limit the frequency range of the main speakers in the system. The objective of adjusting the Low-Pass Frequency control is to ensure that all frequencies are reproduced while minimizing any overlap between the subwoofers and the main speakers. Having both the subwoofer and main speakers reproduce the same frequencies should be avoided, as it results in very irregular response, since some frequencies are reinforced when they happen to be in phase while others are canceled because they are out of phase. Phase Switch Nom. Min Max Figure 15: Rear-panel controls and connectors Adjusts the variable 50Hz – 150Hz low-pass crossover, which determines the highest frequency at which the B120 reproduces sounds. Set the crossover to a lower frequency setting, between 50Hz and 100Hz, when using larger main loudspeakers that can comfortably reproduce some low-frequency sound. With a lower frequency setting, the B120 subwoofer concentrates on reproducing the deep bass required by contemporary music and film soundtracks. Set the crossover to a higher frequency, between 100Hz and 150Hz, for smaller bookshelf loudspeakers that do not extend to the lower bass frequencies. If the frequency control is set too high, the bass sounds “boomy” and can overpower the overall sound of the listening room. If the frequency control is set too low, some low frequency sound may be difficult to hear, or may be absent altogether. This control has no effect when using the Sub In input or if the Low-Pass Switch, shown in Figure 17, is set to Off (Normal) while using the wireless input, because in both cases the receiver/processor sets the crossover frequency. 180 Phase Figure 16: Phase switch Compensates for the absolute phase of the subwoofer’s output relative to the front speakers. Some associated electronics can invert the absolute phase. Use this switch to correct such occurrences. Proper phase adjustment can also depend on variables such as subwoofer placement and listener position. Use this switch, shown in Figure 16, to maximize bass output at the primary listening position. • Select the 0o setting to set the B120 acoustic output in phase (0 degrees) with the input. • Select the 180o setting to invert the B120 acoustic output (180 degrees) relative to the input.

Your authorized Revel dealer can make the appropriate measurements, using suitable equipment to ensure optimal results. Power Switch The Concerta B120 subwoofer can be connected wirelessly by using the optional TX1 transmitter, shown in Figure 19. The TX1 transmitter utilizes advanced wireless transceivers which operate in the 2.4GHz frequency band – the same frequency band used for wireless home networks and high-quality cordless phones. This high-frequency band allows the wireless transmission of high-quality sound to remote locations. One TX1 transmitter can support up to two B120 subwoofers. A third or fourth subwoofer may be connected by using an additional TX1 transmitter. The TX1 Package Includes: 1 x Transmitter module Connects or disconnects power from the AC input cord. During periods of intermittent use, the Power Switch can be left on. Turn off the Power Switch for extended periods of nonuse. 1 x Power supply for transmitter 1 x 120V AC power cord for transmitter power supply 1 x 230V AC power cord for transmitter power supply – Shuko plug AC Input Cord Provides power to the B120 through the power cord. 1 x 230V AC power cord for transmitter power supply – UK plug 1 x 6' (1.8m) audio stereo cable, RCA-RCA 1 x Wall-mount bracket for transmitter 2 x Panhead M3 x 4 machine screws for attaching wall-mount bracket to transmitter 4 x Small, round, self-adhesive feet – to be attached on transmitter’s left-side panel if transmitter is to be used vertically 12 Revel Concerta B120 Owner’s Manual HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 13 ID Codes To use the wireless connection option with the B120 subwoofer, you must have at least one optional TX1 transmitter. 1. Connect an RCA patch cable from the Subwoofer or LFE output on the processor/receiver to the Sub In connector on the B120 rear panel, as shown in Figure 21. Note Some processors incorrectly label the subwoofer output as LFE; others offer both an LFE and a Subwoofer output. If there is no labeled subwoofer output, use the LFE output. If the output has labeled connections for both LFE and Subwoofer, use the Subwoofer output. Figure 20: ID code selector The ID Code identifies the channel in which the wireless system operates. This is particularly important if you have more than one set of subwoofer transmitters and receivers in operation, or in the unlikely event that the subwoofer(s) experience(s) interference with other wireless equipment. Four different channels are available and can be set from the rear panels of the subwoofer and the TX1 transmitter. The subwoofer and transmitter MUST be set to the same channel; otherwise, the wireless system will not function. To Set the ID Code: 1. Adjust the four-position ID Code selector, shown in Figure 20, to the desired channel on the rear panel of the TX1 transmitter. 2. Plug the supplied power cord of the TX1 transmitter between the power connector on the TX1 transmitter and an electrical wall outlet. 3. Set the ID Code on the transmitter and subwoofer to the same position, as described in the “ID Codes” section. When the ID Code is properly set, the LED on the rear panel of the B120 subwoofer lights in orange. 4. Set the Low-Pass switch on the rear panel of the B120 to the Off (Normal) position for most installations. See the following section, “Low-Pass Switch,” for more information about this switch. Low-Pass Switch 2. Then set the same channel on the ID Code selector on the rear panel of the subwoofer.
