Dear Friend and Valued Customer

Welcome to the REL Family. If you already belong, welcome back!

Shortly after introducing the Classic 98, we began to receive requests from customers and dealers to deliver a larger, more powerful model. Anticipating this request, we proactively developed a game plan and specific amplifier/driver combinations to a high level even before launching the smaller 98. Whilst Classic 99 retains the walnut veneer and vintage form factor of a late 90’s era REL, it also boasts 450 watts and a long travel 12” (300mm) bass driver. It would thus be easy to see this as simply a larger/higher output/deeper bass version of the Classic 98.

You would be wrong.

During our usual battle to achieve refinement we investigated shifting cabinet volumes, specific insulation types, and numerous refinements to the drivers and filters. And we began to see something emerging. Something special.

We present you with Classic 99. A model that is far more than the obvious massive increase in power, and hence, output. A model whose 12” driver and cabinet yields far deeper bass extension. A subwoofer larger, heavier, more substantial than its fraternal mate, Classic 98.

Classic 99 is special because in addition to playing 30% louder, in addition to extending some 4 to 5Hz lower in our development studio, it is simply BETTER. Better in that way that REL always seeks, in ways both large and small. And in ways that result in inverse improvements. These are nuanced enhancements that elevate sound quality, transparency, and dynamic range that one would not anticipate from simply a more powerful model. Classic 99 is more transparent throughout the entire audio range. It is capable of greater dynamic contrasts both large and small, it is both more subtle and more outright thunderous. And it is more dexterous and lighter on its feet, which is a rare and beautiful thing to hear.

It is also a crushingly powerful theatre subwoofer, especially when used as rear channel subs in a large HT/3D-enhanced system; a REL method of achieving Dolby’s stated goal of providing deep, extensional bass response throughout ALL the channels of theatre whilst also delivering exceptional .1/LFE special effects-rich bass. Its use in the rear channels is spectacular. As is its value; we’ve worked, as always to keep our prices as reasonable as possible.

This is a special accomplishment that allows us to push the envelope in multiple directions simultaneously and still deliver remarkable value.
Enjoy – John Hunter

Connectivity and Functionality

HIGH LEVEL INPUT

Connections should be made to the same binding post on main amplifier as the main speakers. Red tomain amplifier right speaker positive terminal, yellow to amplifier main left speaker positive terminal and black to a ground lug or chassis screw. See Connecting and setting up section below for details on integration with Class D and Differential type amplifier designs. Plug the Neutrik® Speakon® plug into the HIGH LEVEL Speakon® socket.

.1/LFE INPUT

This requires an RCA to RCA cable and is a dedicated true .1 Channel. This circuit therefore eliminates the normal Natural RollOff™ Crossover and passes the .1 Low Level signal through with only the required 120Hz fourth-order filter.

LOW LEVEL INPUT

This RCA input allows for conventional connection from a preamplifier. This connection is necessary when using powered speakers or when connecting to certain soundbars. Connect from either the left or right low level output from a pre-amplifier to the REL’s LOW LEVEL INPUT RCA.

Phase Switch

Used to set phase. Phase selection affects all inputs (High Level, Low Level and .1/LFE). Used to set Phase to 0 or 180 degrees.

Crossover

The Crossover affects High and Low Level inputs. The .1/LFE signal does not pass through the Crossover circuit.

Connecting Up

Always switch off your system before disconnecting any wires.

To increase the versatility of connecting up, the Classic 99 models have three separate inputs. A High Level input socket, a .1/LFE RCA input, and a Low Level RCA input. This is to facilitate use with both two-channel stereo systems and AV surround sound systems.

The High Level, unbalanced, dual-channel (stereo) input is via a Neutrik® Speakon® connector is designed to accept the stereo (two-channel) signals from the speaker terminals of your receiver, integrated amplifier or basic amplifier. This has the advantage of ensuring that your subwoofer receives exactly the same signal as the main speakers, which means that the character of the bass from the main system is carried forward into the Sub-Bass System.

This is a very important point and together with REL’s Natural RollOff™ circuitry, ensures far superior system integration of the Sub-Bass System with the main system.

STOP! Please read the following or damage can occur. Do not force the Neutrik Connector into its socket on the rear of the amplifier. Please study the Neutrik and note that the cable’s black and blue plug has a black key, a part that locates into a corresponding slot on the amplifier. Line up the cable’s connector with this slot on the amplifier, insert fully into socket and rotate clockwise until a soft “click” is heard.

To remove the Neutrik® Speakon® plug, grip body of plug, place thumb on chrome lever, move lever backwards, rotate plug anticlockwise quarter turn and withdraw.

There is a single RCA socket for Low Level connection to the output of a stereo preamplifier or receiver. Another single RCA socket connects to the .1/LFE output of a home cinema processor.

HIGH LEVEL and .1/LFE inputs can be used simultaneously. The benefits are two- fold when used with a home cinema processor. The .1/LFE input reproduces the .1/LFE channel and the High Level connection underpins the main front speakers. The main front speakers should be set to the ‘Large’ option on the processor. See “Theatre Applications” for more information.

REL Set-Up Made Simple

REL products are not traditional subwoofers, but true Sub-Bass Systems. A REL is designed to augment the performance of “full range” speaker systems in order to provide, in certain cases, linear response below 15Hz. Therefore, for the moment, please set aside everything you’ve been taught about subwoofers and how they are integrated into a stereo or home cinema system. REL Sub-Bass Systems set-up and positioning differs from conventional subwoofers. A REL will take advantage of physics and room acoustics to provide deep pressurization as no traditional subwoofer can. It is important that you bring to the set-up process a willingness to do things a little differently in order to obtain these superior results. The end result of your labors will be an utterly seamless integration of true deep bass to a sound system, regardless of the main speakers’ low bass capability.

Basic set-up should take no more than ten to fifteen minutes to accomplish once connected.

Two Things Before You Begin

1. It is helpful to know that you will almost always connect the REL to the input on the rear panel labeled “HIGH LEVEL INPUT.” This connection is made using the supplied 33’ 6” (10 meters) cable, the bare leads of which connect to the speaker output terminals of the power amplifier. The easy and foolproof connection at the REL is done with a Neutrik® Speakon® connector. The purpose of connecting to the speaker output terminals is one of the unique secrets of REL’s success. By connecting to the HIGH LEVEL INPUT on the REL from the amplifier, you build forward the sonic signature of your main system, including the tonal balance and timing cues of the entire electronics chain. In this way, the REL is fed the exact signal that is fed to the main speakers
2. When possible, the REL should be placed in one of the corners behind the speakers. Remember, we are dealing with true LOW bass pressurization with RELs. Low bass pressurization below 40Hz is best derived from corner placement, where the most linear and efficient low bass can be produced because the subwoofer is able to take advantage of the tangential (corner-to-corner) axis which is typically the longest axis in a room. Corner positioning requires drawing the subwoofer slowly out from the corner after Phase, Gain and Crossover settings have been properly set. Draw it on a 45 degree diagonal away from the corner while moving slowly, listening for small increases in deep bass energy. Pause and assess each time a bass node is encountered. Generally, a range between 4”(100 mm) and 1’ (305 mm) out from the corner will result in achieving cleaner, more open sounding bass, while retaining good deep bass.

Connecting and Setting Up

High level connection, using the enclosed cable with the Neutrik® Speakon® connector, is always the first choice. This connection can be made without affecting the performance of the amplifier because the REL’s amplifier input impedance is 150,000 ohms, in effect producing NO additional load on the rest of your system.

• The standard High Level hook up procedure is: attach the red wire to the amplifier’s right positive speaker output terminal; attach the yellow wire to the amplifier’s left positive speaker output terminal; attach the black wire to a ground lug on the amplifier or a pre-amp or a chassis screw; plug the Speakon® connector into the Sub-Bass System’s HIGH LEVEL INPUT.
  Standard High Level
  
  

• • For Differential(i.e. fully balanced) amplifiers using one REL, simply use the standard connecting scheme above. Connect the black wire to a ground lug or chassis screw. Should hum occur using this method, the black wire should be allowed to “float” or hang down without connection to ANY terminal.
  Please contact your dealer should there be any questions concerning this or any other hookup procedure
  Differential (i.e. Fully Balanced)
  
  NOTE: Classic 99 models are equipped with internal circuitry to allow connection to many Class D (digital) amplifiers.
  Warning: Do NOT connect the black wire to the main Class D power amplifier’s speaker negative terminal. Some Class D amplifiers produce voltage at the amplifier’s negative terminal and connecting the REL’s black wire will produce an undesirable short to ground. If connecting to a Class D amplifier, follow the above connection procedure for differential amplifiers.

• When connecting RELs to Mono Bloc amplifiers (2) RELs, one for each amplifier, must be used. Connect the black wire of each REL to a ground lug or chassis screw of each amplifier; twist together the red and yellow wires of each REL separately and connect each pair to the positive speaker terminal of the corresponding amplifier channel. In some instances, this will result in exceptionally high gain (output) from the RELs. If it seems simply too high in gain, please remove either the red or yellow wire from the twisted pair. This will reduce output by half and restore a natural dynamic.
  Mono Bloc
  
  If the amplifier is of balanced differential design, please follow the instructions in the section above labeled Differential Connection.
  Mono Bloc Differential
  

• If connecting a single REL as a dedicated centre channel sub, twist together the red and yellow wires and connect these paired wires (red/yellow paired together) to the positive centre channel amplifier terminal. Connect the black wire to a ground lug or chassis screw on the amplifier.
  Dedicated Centre Channel
  
  

• If connecting a REL as a dedicated rear channel sub, connect the yellow wire to the left rear positive speaker terminal; connect the red wire to the right rear positive speaker terminal, connect the black wire to a ground lug or chassis screw. If the amplifier is of balanced differential design, please follow the instructions in the section above labeled Differential Connection.
  Dedicated Rear Channel
  

Low Level connection (via RCA connector) is always an option if High Level connection is not possible. When connecting to the LOW LEVEL INPUTS in a system in which High Level connection is not possible, such as if using internally-amplified speakers, connect left and right RCA cables between the LOW LEVEL INPUT jacks of the REL and the left or right channel output of your preamplifier. In some cases, these channels can be combined with a “Y” cable or a dedicated SUB output.

Please consult your pre-amplifier’s/integrated amplifier’s manufacturer before connecting with a “Y” cable.

When connecting to a home cinema system where there is a .1/LFE channel output, connect a single RCA to RCA cable between the sub output of the processor/receiver and the .1/LFE INPUT jack on the REL.

1. Positioning
   The optimal position for a single REL Classic 99 is in one of the corners behind the main speakers. This position provides 9 dB of mechanical amplification and allows for the most linear true low bass wave launch, owing to the ability to tune the REL’s crossover to the longest distance in the room in order to produce the longest, therefore lowest frequency, bass waves.
   1a Stereo Set-Up of Classic 99
   (see page 19 through 21 for Stereo Set-Up procedure). When this step has been completed, proceed to Number 2, immediately below.

2. The Process
   To begin the set-up process, choose a piece of music that has a repetitive bass line that is very low in frequency. We suggest track 4 from the soundtrack to Sneakers (Columbia CK 53146). This has a repetitive bass drum throughout that gives you plenty of time to move the woofer around, but more importantly, the venue was quite large for this recording, and therefore it has a very deep and large-scale bass signature. This track is perfect for the set-up process and should be played at the highest reasonable level expected for system playback. Working with a partner, one in the listening position and one at the REL manipulating the controls, is the most effective and efficient way to set up the REL. If working alone, the initial steps in the set-up can be very effectively carried out from the location of the REL. Trying to ignore all other music in the track, listen for the bass drum and its effect on the listening room.

3. Phase Orientation
   Once in the corner, we need to adjust for phase. This may be the single most critical step, and because it really is quite simple, it is often over- thought. Keep in mind; the right phase is whichever position is the loudest or fullest. While playing music with true low bass, adjust the crossover to a point where the REL and the speaker are sure to share frequencies at 50Hz on the crossover control, or slightly higher for smaller speakers. At this point turn the HI/LOW LEVEL control up so that both the REL and speaker are roughly equal in volume and then switch, using the phase switch, set phase to 0 or 180 degrees. Again, whichever position is loudest or fullest is the correct position. That is, when the position is working in harmony with your main speakers, reinforcing bass, not canceling it.

4. Corner Fine Tuning
   (When setting up for Stereo Classic 99 it is Possible that Placement is Not Corner Loaded and this Step May be Omitted). The next step is to determine precisely how far from the corner the sub should be placed to achieve the most efficient output, as well as the lowest frequency extension. With the REL fully into the corner, and pointing straight out along the diagonal coming out of the corner, continuing to play the music, slowly pull the REL from the corner on the diagonal, equidistant from both side and rear wall. At a certain point (sometimes a matter of only a few inches, in rare cases a foot or more) the REL will audibly go lower, play louder, and, if it truly locks on to the room and is fully pressurizing it, the air around the REL will seem to be energized, stop right there! This is the correct position from the corner for the REL.

5. Orientation
   Once the position from the corner has been established, the orientation of the woofer must be determined by rotating the REL from an imagined centre point at the rear of the REL. As the REL is moved from one side to the other listen for the greatest level of output and bass linearity. In effect, the REL should be left in the position where it is playing the loudest and lowest.

6. Crossover and Level Settings
   To determine the crossover point, take the volume of the REL (using the HI/LOW LEVEL control) all the way down, and put the crossover to 30Hz. At this point, bring the REL’s volume back up slowly to the point where you have achieved a subtle balance, i.e. the point at which you can just hear the Classic 99 even with the main speakers playing. First, bring the crossover point up until it is obviously too high; now gently reduce frequency to the appropriate setting. For all intents and purposes, this is the correct crossover point. Once this stage has been reached, subtle changes to volume and crossover may be accomplished to provide the last bit of complete and seamless integration. With that, set-up is complete.

Hint : There may be a tendency to set the crossover point too high and the volume of the Sub-Bass System too low when first learning how to integrate a REL with the system, the fear being one of overwhelming the main speakers with bass. In making this common error, the resulting set-up will be lacking in bass depth and dynamics. The proper crossover point and volume setting will increase overall dynamics, allow for extended bass frequencies, and improve soundstage properties. Note, volume adjustments may need to be made to offset the effects of crossover changes. In general, when selecting a lower crossover point, more volume may need to be applied. Higher crossover frequencies will generally necessitate less gain.

Stereo Set-Up of REL Classic 99

Stereo Sub-Bass is advised for the fastest, clearest, deep bass—not for more output. Conventional wisdom has it that stereo subs results in between +3 and +6 db additional output depending upon positioning. In and of itself, this is of only passing interest in most instances since even a single Classic 99 is capable of profound output. What then, is the point to adding a second stereo sub bass Classic 99?

In a word, clarity. Clarity that permits “seeing” back into the farthest reaches of the sound stage. Clarity that illuminates all dimensions of the musicians and the space that they inhabit equally and enhances the natural reality of a great full range system, as only RELs can. Stereo Classic 99 produce clarity, transparency, speed and low-level detail NOT just in the bass but throughout the entire spectrum of music.

Expert Set-Up: Preferable is to bring the subs further out into the room and place them slightly behind and outboard of the main speakers.

1. Set each side up independently. Disconnect the sub that is not being set-up so your complete focus can be given over to the sub that is being set-up. Carefully follow the guidance provided in standard set-up if you are unfamiliar with standard REL set-up procedure for gain, phase and crossover settings.

2. Carefully fine-tune the position of the sub in its recommended location (slightly behind and to the outside of the main speaker) listening for rich powerful room nodes, but focusing on speed and connection with the main speaker. Since there will be a preponderance of output available to a stereo Classic 99 owner, focusing on connection with and blending with the main speaker becomes the primary focus, not merely raw output.
   

3. Once each sub has been carefully tuned, attach the cables for both subs. At this point, the output achieved will be too loud and will require re-setting the volume/gain control of each Classic 99 lower. This is normal as the combined output is likely to be at least 3 db louder with both subs now being used. Using the supplied remote, carefully turn down each sub until perfect balance is achieved. While turning the left or right sub gain down, it is helpful to turn slightly and even lean slightly toward the side that is being adjusted to better achieve focus and a balanced sound level more quickly.

Theatre Applications

For Dolby Digital AC3 or other 5.1 theatre systems, once the standard set-up for two-channel outlined above is complete, the LFE output from the processor or receiver should be connected to the .1/LFE INPUT and appropriate volume adjustments made using the .1/LFE level control. For this configuration, you must set the processor to the “large” or “full range” setting for the left and right speakers in order for the REL to receive the bass signal via the high- level cable. In this configuration, the REL provides support for both the left and right speakers for two-channel listening, and support for the LFE when movies are playing. Most processors will allow you to defeat the subwoofer output when listening in the two-channel mode. The effect of this set-up is one of greatly increased dynamics in the mid-bass range, no bass bloat, and a greater degree of space and timing from the special audio effects. For an even greater sense of space and impact, a second REL connected in parallel to the centre channel will prove to be a dramatic improvement as well. And if that is not enough, a rear REL, both to support the rear channel speakers as well as to evenly distribute LFE through the room, truly completes the full-range sonic picture for state-of-the-art film reproduction.

Running   In

Care taken during run in will be rewarded by many years of pleasurable use. Both the electronics and the drive unit will benefit from an initial period of carefully controlled use. Possible damage may be sustained by running in the unit at too high a volume setting over an extended period. On the other hand, by taking a little care over this initial period, about 24 hours of actual use, a longer life with a higher potential eventual performance is assured.

Care and Polishing

The cabinets are best maintained by using a clean soft cloth on the veneer.

Overload Protection

All REL Sub-Bass Systems are designed as true sub bass speakers. They are designed to reproduce those exceptionally deep notes that are felt as well as heard. This it will attempt to do at whatever volume level you set. If set too high no damage should result because the built-in electronics will limit the cone movement. This electronic control is called Set-Safe™. It constantly and instantaneously monitors the output from the power amplifier and is totally transparent in operation until required. This means it has absolutely no effect on the sound quality of your REL until an overload is detected.

Ordinarily an overload would cause the power amplifier to go into clipping with resultant loss of control over the drive unit. This can cause drive unit damage, and always sounds nasty. Set-Safe™ detects the point of incipient clipping and gently soft-clips the waveform of the signal to ensure actual clipping does not occur. This is a necessarily simplified description of what actually happens, but in effect, Set-Safe™ controls the amplifier and ensures there is minimum risk of amplifier and driver damage caused by over-driving.

A thermal overload device is fitted to all Classic 99 Sub-Bass Systems. If the unit is deliberately over-driven this device will sense the temperature rise and cut the output; recovery time is approximately five minutes. If this happens, it is a warning that the unit is being over-driven and the volume level control should be reduced to a safe level.

Although everything possible has been done to minimize risk of thermal overload failure, there can be no defense against those individuals who deliberately abuse the device. Such damage is NOT covered by warranty. Please remember your REL is there to supplement your main system, not overwhelm it!

Power Saving Efficienc y

All REL Sub-Bass system designs utilize a true POWER ON-OFF switch that affords the owner the ability to turn off their unit completely, without having to unplug the A/C mains cord. When a REL Sub-Bass System is switched off using the POWER ON-OFF switch on the rear panel it draws ZERO power.

In addition to the power switch there is an ALWAYS ON/STANDBY mode switch has two positions.

Up engages the STANDBY circuit and down keeps the unit always on.

The Classic 99 features a standby mode that is enabled when the mode switch on the rear of the unit is set to the “STANDBY” position. In this mode, the input signal is constantly monitored for audio activity. If no audio information is detected over a period of 30 minutes, the unit will enter a low power standby mode in which less power is consumed. When input signal activity is detected, the unit resumes normal operation. By using the standby mode, you can ensure that there is no unnecessary power draw when the unit is not in use.

Note: Due to variations in program material, it is impossible to produce a perfectly reliable standby circuit. Bass rich music or effects will consistently trigger our standby circuit whilst content that is low in volume and possesses little or no bass cannot be relied upon to trip the standby function.

Alternatively, the user has the option to leave the unit in the normal operation mode at all times by selecting the “ALWAYS ON” position of the power mode switch. Leaving a REL on produces the best sonic performance and the most reliable operation. In this mode, the unit will not enter standby regardless of whether or not there is activity at the input. Using this setting ensures that the Classic 99 is ready to react instantaneously to bass transients, whether in music or films.
