    Important Safeguards 1 Read all of these instruc ons. 2 Save these instruc ons for future use. 3 Unplug from the wall socket before cleaning. 4 Do not use near water. 5 Do not place on a stand or table; it may fall causing injury to a child or adult, and damage to the unit. 6 The unit should only be operated from the power source indicated on the panel of the amplifier.
  • Page 3 Welcome to the REL Family Thank you for buying a REL Serie T Sub-Bass System. The Serie T is the result of a state-of-the-art collabora on between our American design and engineering team and our Bri sh produc on team. Serie T is conceived as the most cost effec ve high end product we know how to build.
  • Page 4 Overview: Serie T Sub-Bass Systems Many or most loudspeakers emphasize the mid-bass. This is the range from 50 to 90 Hz. We at REL believe this is an incomplete approach and that loudspeakers need to be extended in the lower frequencies for true full range reproduc on.

  • Page 6 1 Volume Control for .1/LFE INPUT: Use to adjust output level when using .1/LFE input from a 5.1 amplifier or processor. 2 Volume Control for HI/LOW INPUT: Use to adjust output when using either HIGH-LEVEL or LOW-LEVEL input. Do not use both simultaneously. 3 Crossover: Used to select crossover frequency.
  • Page 7 Connec ng Up Always switch off your system before disconnec ng any wires. ALWAYS connect using the REL HIGH LEVEL input, unless your system simply cannot accommodate this. While rare, a few esoteric systems, such as those that deliver a pure digital signal to ac ve speakers preclude this possibility.
  • Page 8 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 integra on of the Sub-Bass System with the main system. HIGH LEVEL INPUT: Connec ons should be made to the same binding post on main amplifier as the main speakers.
  • Page 9 REL Set-Up Made Simple REL products are not tradi onal subwoofers, but are 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 12 Hz. Therefore, for the moment, set aside everything you’ve been taught about subwoofers and how they are integrated into a stereo or home cinema system.
  • Page 10 • The standard HIGH LEVEL hook up procedure is: a ach the red wire to the amplifier’s right posi ve speaker output terminal; a ach the yellow wire to the amplifier’s le posi ve speaker output terminal; a ach 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.
  • Page 11 • If connec ng two RELs in a stereo configura on, connect the black wire of each REL to the nega ve speaker terminal of the corresponding amplifier channel; twist together the red and yellow wires of each REL separately and connect each pair to the posi ve speaker terminal of the corresponding amplifier channel.

  • Page 12 • If connec ng a REL as a dedicated rear channel sub, connect the black wire of the REL to either the le rear or right rear nega ve speaker terminal; connect the yellow wire to the le rear posi ve speaker terminal;...
  • Page 13 Working with a partner, one in the listening posi on and one at the REL manipula ng the controls, is the most effec ve and efficient way to set up the REL. If working alone, the ini al steps in the set-up can be very effec vely carried out from the loca on of the REL.
  • Page 14 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.
  • Page 15 2 In the rear corner (ideally that which is opposite the primary sub), connect a second REL to the rear speakers using REL Theater Reference connec vity. The purpose of the rear channel REL is to ensure proper front-to-rear balance and weight; too o en virtually ALL the power and weight in a theater comes from the front and it produces unnatural weigh ng as well as hot spots.
  • Page 16 When you have accomplished this task, plug all three units in and re-check your gain se ngs as the cumula ve effect of hooking all three up will usually result in, temporarily, excessive output. Work carefully and methodically to reduce the se ngs on primary, then rear, and finally center channel RELs and in a few minutes balance should be restored.
  • Page 17 Power Saving Efficiency All REL Sub-Bass Systems are designed for maximum power efficiency, both when passing a signal through to its resultant output sound into the room and also when silent. REL circuitry allows for “power starva on” opera on under no signal condi ons. This means that when there is a gap in the signal the REL is instantly at maximum power saving efficiency, yet remains at maximum readiness to respond immediately to a sudden transient signal (such as an explosion in a movie) even a er a long quiet period and regardless of level.
