sing the Low-Level Inputs

.1 Input: This requires a phono-to-phono cable and is a dedicated true .1 channel. This circuit therefore eliminates

the normal Natural RollOff Crossover and passes the .1 low-level signal through with only the required 120Hz 4th

rder crossover.

Low-Level Input: This single channel 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 preamplifier output and the other into the low-level input on the sub-bass system. To obtain signal from both

channels requires purchase of a Y-adaptor that is available from most parts stores.

Phase Switch

Phase reversal can be useful as explained in “SETTING UP”.

PHASE SWITCH – Used to set phase

Position 0 / High-Level or LFE: 0 degrees phase

Position 180 / High-Level or LFE: 180 degrees phase

PHASE SELECTION AFFECTS BOTH HI AND LO LEVEL INPUTS

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 12Hz. 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.

Two Things Before You Begin

1 It is helpful to know that you will almost always connect the REL using the input on the rear panel labeled

“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. The easy and foolproof connection at the

REL is done with a Neutrik Speakon connector. The purpose of connecting to the speaker output terminals is

one of the unique secrets of REL’s success. By connecting to the high-level input on the REL from the amplifier,

you build forward the sonic signature of your main system, including the tonal balance and timing cues of the

entire electronics chain. In this way, the REL is fed the exact signal that is fed to the main speakers.
