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 connec1on 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 connec1on
at the REL is done with a Neutrik Speakon connector. The purpose of connec1ng to the speaker output
terminals is one of the unique secrets of REL’s success. By connec1ng 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 1ming cues of the en1re electronics chain. In this way, the REL is fed the exact signal that is fed to the
main speakers.
• When possible, the REL should be placed in one of the corners behind the speakers. Remember, we are
dealing with true LOW bass pressuriza1on with RELs. Low bass pressuriza1on below 40Hz is best derived
from corner placement, where the most linear and efficient low bass can be produced.
High-level connec1on, using the enclosed cable with the Neutrik Speakon connector, is always the first
choice compared with low-level connec1on. This connec1on can be made without affec1ng the performance
of the amplifier because the REL’s amplifier input impedance is 150,000 ohms, in effect not producing any
addi1onal demand whatsoever on the rest of your system. When connec1ng to a home cinema system
where a .1/LFE channel output is present, connect a single phono cable between the sub output of the
processor/receiver and the .1/LFE input jack on the REL.
Se.ng Up
1 Posi,oning: The op1mal posi1on for a REL is in one of the corners behind the main speakers. This posi1on
provides 9 dB of mechanical amplifica1on and allows for the most linear true low bass wave launch,
owing to the ability to tune the REL to the longest distance in the room in order to produce the longest,
therefore lowest, bass waves.
2 The Process: To begin the set-up process, choose a piece of music that has a repe11ve bass line that is
very low in frequency. We recommend track 4 from the soundtrack to Sneakers (Columbia CK 53146).
This has a repe11ve bass drum throughout that gives you plenty of 1me to move the woofer around,
but more importantly, the venue was quite large for this recording and therefore it has a very deep and
large-scale bass signature. This type of track is perfect for the set-up process and should be played at the
highest reasonable level expected for system playback.
