When connecng to a home cinema system where there is a .1/LFE channel output, connect a single phono
cable between the sub output of the processor/receiver and the .1/LFE input jack on the REL.
1 Posioning: The opmal posion for a REL is in one of the corners behind the main speakers. This posion
provides 9 dB of mechanical amplicaon 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 repeve bass line that is
very low in frequency. We suggest track 4 from the soundtrack to Sneakers (Columbia CK 53146). This has
a repeve bass drum throughout that gives you plenty of me 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.
Working with a partner, one in the listening posion and one at the REL manipulang the controls, is the
most eecve and ecient way to set up the REL. If working alone, the inial steps in the set-up can be
very eecvely carried out from the locaon of the REL. Trying to ignore all other music in the track, listen
for the bass drum and its eect on the listening room.
3 Phase Orientaon: Once in the corner we need to adjust for phase. This may be the single most
crical step, and because it really is quite simple, it is oen over-thought. Keep in mind; the right phase
is whichever posion is the loudest or fullest. While playing music with true low bass, adjust the crossover
to a point where the REL and the speaker are sure to share frequencies (about halfway up, or at 12
o’clock on the crossover control, or slightly higher for smaller speakers). At this point turn the HI/LOW
LEVEL control up so that both the REL and speaker are roughly equal in volume and then switch, using
the phase switch, from “0” to “180” phase posions. Again, whichever posion is loudest or fullest is the
correct posion. That is, when the posion is working in harmony with your main speakers, reinforcing
bass, not cancelling it.
