Dear REL Friend Owner, and Valued Customer Dear Congratulations on your purchase of our all new Serie S, the centerpiece of REL’s range of subwoofer offerings. This latest range is the most comprehensive series of upgrades any range has delivered in the nearly three decades that REL have brought you the finest subwoofers extant. S/812 and S/510 deliver up to 60 percent more power, flatter, more extended deep bass, and more extended upper frequency air and detail. Couple that with dramatic upgrades to the .
REL Serie S Rear Panel Connection Legend 1 High Level Output (Neutrik Speakon): Used to connect or “daisy chain” another REL Serie S in tandem. 2 High Level Input (Neutrik Speakon): Used to connect to the main front amplifier speaker terminals. 3 . 1/LFE Balanced Output: Balanced (XLR connector) version of .1/LFE Output. For use only with fully balanced cables. 4 . 1/LFE Balanced Input: Balanced (XLR connector) version of .1/LFE Input. For use only with fully balanced cables.

Connectivity and Functionality High Level Input Connections should be made to the same binding post on main amplifier as the main speakers. Red to amplifier main right speaker red terminal, yellow to amplifier main left speaker red terminal and black to amplifier main speaker black terminal, right or left but not both. 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 HI LEVEL Speakon® socket.
Connecting Up Always switch off your system before disconnecting any wires. To increase the versatility of connecting up, the Serie S models have three separate inputs. A high level input socket, a .1/LFE input consisting of both RCA and XLR connectors, and a low level input that includes two RCA sockets for stereo input. This is to facilitate use with both two-channel stereo systems and AV surround sound systems.
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.
• T he 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 whichever of the amplifier’s ground output terminals is convenient; plug the Speakon® connector into the Sub-Bass System’s high level input. Standard High level • For differential (i.e.
• When connecting RELs to Mono Bloc amplifiers (2) RELs, one for each amplifier, must be used. Connect the black wire of each REL to the negative speaker terminal of the corresponding amplifier channel; 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 connecting a single REL as a dedicated centre channel sub, an insider tip is to consider connecting to the rear of the speaker, rather than routing the REL High Level enable all the way back to the amplifier (unless the amplifier is of Class D or Differential output design). Connect the black wire of the REL to the negative centre channel speaker terminal; twist together the red and yellow wires and connect this paired cable (red/yellow paired together) to the positive centre channel speaker terminal.
When connecting to a home cinema system where there is a .1/LFE channel output, connect a single RCA to RCA or XLR to XLR cable between the sub output of the processor/receiver and the .1/LFE input jacks on the REL. 1 P ositioning: The optimal position for a single REL Serie S is in one of the corners behind the main speakers.
5 O rientation: 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.
Set-Up: When setting up stereo RELs, it is possible to place both units in the front corners of the room, carefully toed-in and placed per normal guidance in this manual. Connect each sub to the speaker terminal outputs based on the following diagrams for standard stereo amp, non-balanced mono blocks or balanced differential mono blocks.
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 S et 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 (see page 14).
Connectivity for Towers of Serie S, Multiple Sub-Bass Systems To render connectivity simple, Serie S provides both inputs and outputs for all connections. Thus, a stack of Serie S can be connected using only one high-level main cable from power amp to REL stack. In a .1 film sound configuration each channel will require a single main .1 cable as well, but additional units’ .1/LFE connections in a tower may be daisy chained to minimize clutter.
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.
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™.
Power Saving Efficiency All REL Sub-Bass System designs utilize a true 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 On-Off switch on the rear panel it draws ZERO power.
