Dear Friend and Valued Customer Thank you for placing your trust in us and welcome to the REL family. While we make products far more expensive than the T/x range, these T/x models are so very important to us. Experience has taught us that if you have a wonderful experience with this range, you will understand in a deeper way what we’re about as a company and be more likely to become a repeat customer in the future.
REL SERIE T/x Rear Panel Connection Legend 1 Wireless Interface Socket: Used to connect to Arrow™ Wireless. 2 Phase: Used to set phase 0-180 degrees. 3 H i/Low Level: Volume control for High/Low Input. Use to adjust output when using either High Level or Low Level input. 4 Crossover: Used to adjust crossover frequency of Hi/Low Level channel. Variable between 20-120Hz.

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).
Connecting Up Always switch off your system before disconnecting any wires. To increase the versatility of connecting up, the Serie T/x 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.
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.
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.
• For differential (i.e. fully balanced) amplifiers using one REL, simply use the standard connecting scheme with the exception of NOT connecting the black wire to a negative speaker terminal. Instead, it should first be allowed to “float” or hang down without connection to ANY terminal. Should hum occur using this method, please try connecting to an unused RCA connector on the rear of a preamp or amplifier.
• 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.
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.
4 Corner Fine Tuning: (When Setting up for Stereo Serie T/x 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.
Stereo Set-Up of REL Serie T/x 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 Serie T/x is capable of profound output. What then, is the point to adding a second stereo sub bass Serie T/x? In a word, clarity.
Mono Bloc Mono Bloc Differential 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 C arefully 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 Serie T/x owner, focusing on connection with and blending with the main speaker becomes the primary focus, not merely raw output.
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™.
