Page 3: Important Safeguards
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 4 Welcome to the REL Family Thank you for buying a REL Gibraltar Sub-Bass System. Gibraltar is carefully hand-built using the finest materials available and is designed for maximum performance. This manual contains important safety informa on as well as helpful advice and should be carefully studied before connec ng the unit. Many or most loudspeakers emphasize the mid-bass.
- Page 5 Introduc on to the Design of the REL Gibraltar Sub-Bass Systems Any design process is a journey. Please follow along as we share lessons gleaned from our three-year journey culmina ng in the birth of a new ultra high performance range for REL Acous cs, Gibraltar™. The REL design team’s goals for Gibraltar were to replicate the extraordinary performance of the much costlier REL Studio III while reducing size and upgrading appearance.
- Page 6 Numerous versions of the cabinet were constructed and evaluated using test instruments and, in par cular, the human ear. Extensive bracing runs the full internal height of each side panel, across the en rety of the crucial top panel, and includes a single fore-and-a integra ng brace much like the spars on a ship that results in an excep onally quiet cabinet.
- Page 7 REL Reference Theater Connec on Gibraltar’s filter, opera ng completely independently of the primary crossover, provides for dedicated .1 inputs and crossover func on. The pure Dolby® Labs .1 protocol is observed featuring a dedicated fourth-order filter fixed at 120Hz. Connec on is via either XLR or RCA sockets for the .1 input. Gain is adjustable completely independently of the high-level connec on.

- Page 9 1 .1/LFE Phono Input: Used to connect to the .1/LFE output of a surround-sound processor. 2 .1/LFE Phono Output: Used to connect or “daisy chain” another REL G-Series in tandem. 3 Le & Right Channel Low-Level Phono Input: Used to connect low-level signals to the sub-bass system from the output of a preamplifier, integrated amplifier or receiver.
- Page 10 Connec vity and Func onality High-Level Input: Connec ons 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 le speaker red terminal and black to amplifier main speaker black terminal, right or le but not both.
- Page 11 Remote Control Battery Installation Gibraltar’s remote control unit requires two AAA ba eries. These are not installed but are supplied. To install or replace ba eries in the remote control unit, first remove the bo om aluminum cover by using the supplied 2.5mm allen key to loosen the two visible screws.
- Page 12 HIGH LEVEL and .1/LFE inputs can be used simultaneously. The benefits are two fold when used with a home cinema system. The low level input reproduces the .1 Sub/LFE channel and the high level connec on underpins the main front speakers. The main front speakers should be set to the ‘large’ op on on the processor.
- Page 13 Differen al or Class-D Amplifier Connec on • For differen al (i.e. fully balanced) amplifiers using one REL, simply use the standard connec ng scheme with the excep on of connec ng the black wire to chassis ground (i.e. a metal bolt or screw, preferably not painted or anodized, on the chassis of the power amp or receiver), not to a nega ve speaker terminal, and then connec ng into the HIGH-LEVEL INPUT on the REL.
- Page 14 Dedicated Center Channel Sub Connec on • If connec ng a single REL as a dedicated center channel sub, connect the black wire of the REL to the nega ve center channel speaker terminal; twist together the red and yellow wires and connect this pair to the posi ve center channel speaker terminal.
- Page 15 Connec ng Gibraltar Towers For higher levels of low-frequency output, you may want to use mul ple sub-bass systems. To facilitate this, the Gibraltar uses a rear panel high-level connector to “daisy chain” units when stacked ver cally or placed next to each other.
- Page 16 Using the Remote Control to Address Mul ple Sub-Bass Systems The address selec on is accessed on the remote control unit by removing the bo om aluminum cover in the same way as outlined in the sec on “Ba ery Installa on”. Removing the cover will reveal a small rotary switch labeled “ADDRESS”...
- Page 17 Before You Begin • 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 connec on is made using the supplied 34’ 10” (10 meters) cable, the bare leads of which connect to the speaker output terminals of the power amplifier.
- Page 18 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 19 and crossover can be made to provide the last bit of complete and seamless integra on. 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.
- Page 20 REL Theater Reference™ Home Cinema Applica ons For Dolby® Digital AC-3 or other 5.1 theater 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.
- Page 21 connect the remaining black lead to the nega ve (black) terminal on the rear of the speaker. The purpose of the third “center” REL is to ensure the center channel can keep up with the scale, weight and dynamics the main system now has. Loca on should be anywhere from the opposite corner of the front wall to somewhere in the middle of the front wall, listen for best integra on with the center channel speaker.
- Page 22 Care and Polishing The cabinets are best maintained by using a light automo ve spray-on wax and a microfiber cloth. We use a spray-on made by a company called Griot’s Garage™. While this may not be available in all markets, you can use a similar product.
- Page 23 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 so clips the waveform of the signal to ensure actual clipping does not occur.
