Operation Manual

sing 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.

This connectivity allows for the same amplifier output signal to be designated to each sub-bass system individually. Simply

use the optional cable (Neutrik Speakon-to-Neutrik Speakon) to connect from the “HIGH LEVEL OUTPUT” of the first sub-bass

system to the “HIGH LEVEL INPUT” of the second unit.

When “daisy chained” each sub-bass system retains its autonomy and each will need to have its output level, crossover

point, phase, etc adjusted individually.

This arrangement provides unrestricted flexibility for in-room integration and fine-tuning of all audio parameters.

For multi-channel home cinema systems, the same procedure is followed except the optional (Phono-to-Phono) cable

is used to connect the first sub-bass system “.1/LFE OUTPUT” to the “.1/LFE INPUT” of the second unit. As is typical for

REL, both high-level and .1/LFE inputs can be used together and adjusted simultaneously offering the ability to blend

both signals to your taste.

To protect the REL G-Series fine furniture grade cabinetry when stacking, optional rails that replace the metal feet are

available. The rails measure 23.5” L x 4”W x 2”H and have a felt covering on the bottom surface. The kit contains all

hardware necessary to attach two rails.

Using the Remote Control to Address Multiple Sub-Bass Systems

The address selection is accessed on the remote control unit by removing the bottom aluminum cover in the same way

as outlined in the section Battery Installation. Removing the cover will reveal a small rotary switch labeled “ADDRESS”

next to the battery holder. Factory setting is position “0”. With the remote control unit powered off (locked mode), this

switch can be rotated using a small slotted screwdriver to select one of sixteen possible address positions, “0” through

“F”. Once a selection has been made, replace the back cover and turn the remote control unit on (unlocked mode). At

this point the remote control will not operate the subwoofer. In order to pair the remote control unit with the subwoofer,

point the remote control unit’s emitter at the subwoofer’s LED display and hold the PHASE switch for 5 seconds. The

LED under the CROSSOVER control will flash once and the display on the sub-bass system will read “- - -“ followed by

a confirmation noting the selected address. The sub-bass system is now paired with the specific remote control unit

and will not function with a different remote. In a system with multiple sub-bass systems, change each address one unit

at a time with the sub-bass systems not being changed switched-off to avoid inadvertently changing the addresses of

multiple units.

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 down to 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. REL Sub-Bass Systems set-up and positioning differs from conventional subwoofers. A REL

will take advantage of physics and room acoustics to provide deep pressurization as no traditional subwoofer can.

It’s important that you bring to the set-up process a willingness to do things a little differently in order to obtain these

superior results. The end result of your labours will be an utterly seamless integration of true deep bass to a sound

system, regardless of the main speakers’ low bass capability.

Basic set-up should take no more than ten to fifteen minutes to accomplish once connected.
