Page 2: Important Safeguards
This item is heavy. To avoid risk of injury, take care when handling. Welcome Thank you for buying a REL G1 Sub-Bass System. The G1 is carefully hand-built using the finest materials available and is designed for maximum performance. This manual contains important safety information as well as helpful advice and should be carefully studied before connecting the unit. - Page 3 .1/LFE film sound. Class D amplifiers pose no problem to the G1 as it incorporates REL-D™, a proprietary input for their use. Setup and adjustment is made simple and easy by a unique digital rotary control based remote control. This small round handheld remote control is capable of making all critical adjustments from your listening position.
- Page 4 Any design process is a journey. Please follow along as we share lessons gleaned from our three-year journey culminating in the birth of a new ultra high performance range for REL Acoustics, GIBRALTAR™. The REL design team’s goals for Gibraltar are a simple attempt to replicate the extraordinary performance of the much costlier REL Studio III while reducing size and upgrading appearance.
- Page 5 REL employ an expensive but, in our vast experience, ultimate circuit topology for Gibraltar. A linear, Class AB power amplifier using 6 MOS-FETS for the G1 and 4 for the G2 backed by state of the art power supply and a power transformer with vast over-specification.

LED Display An LED display is located on the lower front of the G1. All functions that are user adjustable via the remote control can be seen here. The display reverts to off a few seconds after adjustment. - Page 8 Low-Level Input: This stereo phono input allows for conventional connection to a preamplifier and should be used in the rare event that a high-level connection proves incompatible. Connect as shown below. Plug one end into the low-level output of the amplifier/processor and the other end into the stereo low-level inputs on the G1.

Using Multiple Sub-Bass Systems For higher levels of low-frequency output, you may want to use multiple sub-bass systems. To facilitate this the REL G1 uses a rear panel high-level connector to “daisy chain” units when stacked vertically or placed next to each other. -
Page 10: Connecting And Setting Up
Two Things Before You Begin 1 It is helpful to know that you will almost always connect the REL to the input on the rear panel labelled “HIGH LEVEL INPUT.” This connection 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 11 3 Phase Orientation: Once in the corner we need to adjust for phase. This may be the single most critical step, and because it really is quite simple, it is often over-thought. Keep in mind; the right phase is whichever position is the loudest or fullest.
- Page 12 Technical The G1 model uses an unusual method of bass loading. It is designed to operate below normal system resonance. This has been achieved without the normal form of bass boost or electronic equalization. Instead of a constantly increasing bass equalization response, we simply ensure there is sufficient amplifier gain to drive the speaker unit to its maximum excursion level at whatever the designated lowest operating frequency is, and then cut the bass at a controlled rate of 12 dB per octave above this frequency.
