  • Page 9 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.
  • Page 10 REL Classic 99 Rear Panel Connection Legend 1 HI/LOW LEVEL INPUT: Used to adjust the output of either the High Level or Low Level input. 2 .1/LFE LEVEL: Used to adjust output level when using .1/LFE Input from a surround sound processor.

  • Page 12: Connectivity And Functionality

    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.
  • Page 13 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.
  • Page 14 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.
  • Page 15 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.
  • Page 16 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.
  • Page 17 • 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.
  • Page 18 • 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.
  • Page 19 .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...
  • Page 20 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.
  • Page 21 +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.
  • Page 22 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...
  • Page 23 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.
  • Page 24 .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.
  • Page 25 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.
  • Page 26 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.
