4Revel Concerta B120Owner’s ManualTo Unpack the B120: Figure 1: Unpacking the B120 subwoofer1. Place the packing carton upright and fully open thetop flaps. Refer to Figure 1.2. Without allowing the top flaps to close, stand the packingcarton upside down by carefully “rolling” the cartonover on a soft surface, such as carpet.3. Lift the packing carton off of the subwoofer. Usecaution to avoid damaging the cabinet and objectslocated 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 cableSUBWOOFERPLACEMENTBelow 300Hz, loudspeaker and listener locations have a profound impact on the way sound is reproduced.All rooms have “standing waves,” by which certainfrequencies are emphasized or diminished. Theircomplex patterns can combine to introduce tremendoussound coloration at low frequencies.The Concerta B120’s Equalization controls can help tocompensate for these effects, but no electronic systemalone can fully compensate for the dramatic effects ofroom acoustics. Every room has locations where “nulls”at specific frequencies occur. These cancellations of thesound are like “black holes,” which no amount ofequalization can fill. The best results are alwaysachieved through careful placement of both theloudspeakers and the listening position. Preferableplacement can be determined through the use ofcomputer modeling programs, or by trial-and-errormeasurements. For optimal results, find the bestloudspeaker and listener locations first, then use theB120 Equalization controls for fine-tune adjustments.To help determine good locations for the subwoofer(s)and the listener(s), it is recommended that you makehigh-resolution in-room response measurements. Yourauthorized Revel dealer can make the appropriatemeasurements, using suitable equipment to ensureoptimal results.NoteMany sound-measurement devices are notaccurate enough to properly measure low-frequency performance in a listeningroom, since room boundaries can oftencause modes (standing waves) with verynarrow-band peaks and dips. Check withyour authorized Revel dealer to confirmthat your measurement equipment issuitable for accurate, high-resolutionmeasurements.OMtop-EPEsubwooferplastic bag bottom-EPE grillebeauty carton HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 4

5Revel Concerta B120Owner’s ManualGENERAL PLACEMENTGUIDELINESThe following placement suggestions are followed bydiagrams for recommended subwoofer locations. Due to thenature of room acoustics, the best approach is to experimentwith different listening locations, as well as loudspeakerlocations, to obtain the best sound at low frequencies.Generally, it’s best to place the Revel Concerta B120subwoofer(s) near solid walls to reinforce bass response.Avoid placing the subwoofer(s) near windows, which canrattle and transmit sound to the outside world. Placing asubwoofer in the corner of a room, as shown in Figure 2,results in maximum reinforcement, which contributes tolower distortion. Most dips cannot be equalized, but theycan be minimized through the optimal placement of thesubwoofer(s) and listening position.Figure 2: Single B120 subwooferPlacing two Revel Concerta B120 subwoofers in oppositecorners of the listening room, as shown in Figure 3,results in smoother low-frequency response and moreconsistent sound throughout the listening area.Figure 3: Two B120 subwoofers in opposite corners If using two B120 subwoofers but corner placement isnot an option, try placing the subwoofers at the midpointsof opposite walls, as shown in Figures 4 and 4a.Figure 4: Two B120 subwoofers at opposite walls Figure 4a: Two B120 subwoofers at opposite walls Use of a modeling program or trial-and-error measurementsto further determine the best locations is recommended.Using precise measurements to determine subwooferplacement minimizes the response dips due to standing-wave cancellation that cannot be corrected by equal-ization. Ask your authorized Revel dealer for moreinformation and assistance.B120B120B120B120B120B120B120HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 5

6Revel Concerta B120Owner’s ManualFor large rooms (greater than 2000 to 3000 cubic feet,or 57 to 85 cubic meters), consider adding one or moreadditional B120 subwoofers for greater bass output andlower 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 isusually obtained by placing one pair at the midway pointof the opposite front and back walls, and a second pairat the midway points of the side walls, as shown inFigure 5. Your authorized Revel dealer can use in-roommeasurements to fine-tune the locations, accounting for variation in construction among the room walls.Figure 5: Four B120 subwoofers at midpoints Another option is to place four Concerta B120 subwoofersin the corners of the listening room, as shown in Figure 6.Figure 6: Four B120 subwoofers in the corners A third alternative is to place the four B120s on the frontand back walls at one-third of the distance into the room,as shown in Figure 7.Figure 7: Four B120 subwoofers at the front and back The placement of the other system loudspeakers in thelistening 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 measurementsto 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 timespent determining the ideal placement locations.Remember that peaks (below the subwoofer crossoverfrequency) can be minimized or eliminated by theproper adjustment of the Concerta B120’s Equalizationcontrols, but dips cannot be corrected via equalization.Therefore, the most important objective is to findlocations that result in the minimum number (andseverity) of dips. Contact your authorized Revel dealerfor assistance in determining the proper placement ofyour Revel loudspeakers and subwoofers.After placing the B120 subwoofer(s), begin playback of a familiar music or film source that has substantial basscontent. Listen from the primary listening position, increasingthe overall volume of the system to a comfortable level.Adjust the Subwoofer Level (volume) control until youobtain the desired blend of bass. Also, test the subwooferlevel by playing a recording of a deep male voice. Settingthe subwoofer level (or crossover frequency) too highresults in unnaturally “thick” or “boomy” vocal reproduction.Bass response should not overpower the room, andshould be adjusted to achieve a harmonious blendacross the entire audible range.If you are using a multichannel receiver or processorwith a subwoofer output, it’s preferable to use theSubwoofer Level adjustment on the processor. Set theB120 Level control to the indicated “Nominal” position.B120B120B120B120B120B120B120B120B120 B120B120 B120HSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 6

7Revel Concerta B120Owner’s ManualNoteSetting the level of the subwoofer in relationto the left and right front speakers is of criticalimportance because it is essential that thesubwoofer integrate smoothly with the entiresystem. Setting the level too high results in an overpowering bass response. Setting thelevel too low negates the benefits of theB120 subwoofer.MAKINGCONNECTIONSCAUTION!Never make or breakconnections unless all systemcomponents are powered off.Figure 8: Rear-panel input connectors This section provides typical examples of cableconnections with different system configurations anddevices. Review the owner’s manuals for associatedaudio components to determine their connectionrequirements.The B120 subwoofer input connectors are located on therear panel. Two gold-plated RCA connector options areavailable – Sub In Low-Pass Disabled (Normal) and L/RLow-Pass Enabled – as shown in Figure 8.In most cases, you’ll use the Sub In connector, as it’sdesigned for multichannel use. This input bypasses thelow-pass filter, and is the appropriate input for mostinstallations. This connector should be used when thereis a dedicated subwoofer output available on the audioprocessor or receiver.NoteSome processors incorrectly label the subwooferoutput as LFE; others offer both an LFE and a Subwoofer output. If there is no labeledsubwoofer output, use the LFE output. If theoutput has labeled connections for both LFEand Subwoofer, use the Subwoofer output.The L (Left) and R (Right) connectors on the rear panel of the B120 are for use with 2-channel applications, where there is nodedicated subwoofer output available. Theseinputs are automatically crossed-over by theadjustable Low-Pass Crossover control on therear panel. Having the low-pass filter enabledhelps offset the fact that most 2-channelsystems do not perform any high-pass filteringon the main speakers, minimizing theadvantages of using a subwoofer. Theseconnectors should be used in 2-channelapplications where the receiver or preamplifierlacks a dedicated subwoofer or LFE output.NoteThe Concerta B120 subwoofer has a thirdconnection option – wireless connection isalso available when coupled with the optionalTX1 transmitter. Refer to the “WirelessConnection” section found later in this manualfor additional details regarding this option.Multichannel Applications –Typical ConnectionFigure 9: Typical connection This configuration is for use with multichannelprocessors or receivers that have a single dedicatedSubwoofer or LFE output connector.Connect the supplied RCA patch cable from the Subwooferor LFE output on the processor/receiver to the Sub Inconnector on the B120 rear panel, as shown in Figure 9.B120 Input PanelReceiver/ProcessorSubwooferOutputHSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 7

Connect an RCA patch cable between the left mainoutput 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 mainoutput on the receiver/preamplifier to the R(ight) Low-Pass Enabled connector on the B120 rear panel.NoteThis configuration applies to receivers withpreamplifier outputs or to preamplifier/power amplifier configurations in which thereare two sets of Main outputs. If the receiverhas jumpers from the Pre- or Main-Out to theAmp in connectors or if the preamplifier hasonly one set of Main-Out connectors, a Y-adapter should be used to send the samesignal to both the main power amplifier andthe subwoofer(s). Tape Out or Record Outconnectors cannot be used.Multichannel Applications –Multiple Subwoofer ConnectionsFigure 11: Connection to multiple B120 subwoofersThis configuration is for use with multiple B120 subwoofersand a multichannel processor or receiver.NoteThe supplied single-RCA patch cord can beused in any of the three connections describedbelow, but you will need to purchase an RCA Y-adapter and possibly an additionalsingle-RCA cable.1. Connect an RCA patch cable from the Subwoofer orLFE output on the processor/receiver to the singleinput on the Y-adapter, as shown in Figure 11.2. Connect an RCA patch cable from one of the outputsof the Y-adapter to the Sub In connector on the firstB120 rear panel.3. Connect an RCA patch cable from the second outputof the Y-adapter to the Sub In connector on thesecond B120 rear panel.NoteAdditional B120 subwoofers may be connectedby using additional Y-adapters – by placing an additional Y-adapter input connector intoone of the output connectors of the first Y-adapter.B120 Input PanelReceiver/PreamplifierMainOutputsMainOutputsB120 Input PanelSub 2B120 Input PanelSub 1Receiver/ProcessorSubwooferOutputHSGP1031RC_B120_OM.qxd 6/4/08 10:30 AM Page 8

11Revel Concerta B120Owner’s ManualSubwoofer Level (Volume)ControlProvides basic volume adjustment for the subwoofer.Begin with this control set to the nominal “12 o’clock”position.Low-Pass Frequency ControlFigure 15: Rear-panel controls and connectorsAdjusts the variable 50Hz – 150Hz low-pass crossover,which determines the highest frequency at which theB120 reproduces sounds. Set the crossover to a lowerfrequency setting, between 50Hz and 100Hz, when usinglarger main loudspeakers that can comfortablyreproduce some low-frequency sound.With a lower frequency setting, the B120 subwooferconcentrates on reproducing the deep bass required by contemporary music and film soundtracks. Set thecrossover to a higher frequency, between 100Hz and150Hz, for smaller bookshelf loudspeakers that do notextend to the lower bass frequencies.If the frequency control is set too high, the bass sounds“boomy” and can overpower the overall sound of thelistening room. If the frequency control is set too low,some low frequency sound may be difficult to hear, ormay 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 toOff (Normal) while using the wireless input, because in both cases the receiver/processor sets the crossoverfrequency.NoteThis control does not limit the frequencyrange of the main speakers in the system. Theobjective of adjusting the Low-Pass Frequencycontrol is to ensure that all frequencies arereproduced while minimizing any overlapbetween the subwoofers and the main speakers.Having both the subwoofer and main speakersreproduce the same frequencies should beavoided, as it results in very irregular response,since some frequencies are reinforced whenthey happen to be in phase while others arecanceled because they are out of phase.Phase SwitchFigure 16: Phase switchCompensates for the absolute phase of the subwoofer’soutput relative to the front speakers. Some associatedelectronics can invert the absolute phase. Use this switchto correct such occurrences. Proper phase adjustmentcan also depend on variables such as subwooferplacement and listener position. Use this switch, shownin Figure 16, to maximize bass output at the primarylistening position.• Select the 0osetting to set the B120 acoustic output in phase (0 degrees) with the input.• Select the 180osetting to invert the B120 acousticoutput (180 degrees) relative to the input.Low-Pass Filter Switch (Wireless Operation Only)Figure 17: Low-pass switchActivates or deactivates the Low-Pass Frequency Controlwhen using an optional TX1 wireless transmitter.

13Revel Concerta B120Owner’s ManualID CodesFigure 20: ID code selectorThe ID Code identifies the channel in which the wirelesssystem operates. This is particularly important if youhave more than one set of subwoofer transmitters andreceivers in operation, or in the unlikely event that thesubwoofer(s) experience(s) interference with otherwireless equipment.Four different channels are available and can be set fromthe rear panels of the subwoofer and the TX1 transmitter.The subwoofer and transmitter MUST be set to the samechannel; otherwise, the wireless system will not function.To Set the ID Code:1. Adjust the four-position ID Code selector, shown inFigure 20, to the desired channel on the rear panel of the TX1 transmitter.2. Then set the same channel on the ID Code selector on the rear panel of the subwoofer.If you are using multiple sets of B120 subwoofers andTX1 transmitters, ensure that each subwoofer/TX1transmitter pair are set to different ID Code channels.Connecting the TX1Transmitter to the SubwooferFigure 21: Wireless transmitter rear-panel connectionTo use the wireless connection option with the B120subwoofer, you must have at least one optional TX1transmitter.1. Connect an RCA patch cable from the Subwoofer orLFE output on the processor/receiver to the Sub Inconnector on the B120 rear panel, as shown in Figure 21.NoteSome processors incorrectly label the subwooferoutput as LFE; others offer both an LFE and a Subwoofer output. If there is no labeledsubwoofer output, use the LFE output. If theoutput has labeled connections for both LFEand Subwoofer, use the Subwoofer output.2. Plug the supplied power cord of the TX1 transmitterbetween the power connector on the TX1 transmitterand 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 rearpanel of the B120 subwoofer lights in orange.4. Set the Low-Pass switch on the rear panel of the B120to the Off (Normal) position for most installations.
