Low-level connecon (via RCA connector) is always an opon if high-level connecon is not possible. When
connecng to the low-level inputs in a system in which high-level connecon is not possible, such as if using
internally-amplied speakers, connect le and right RCA cables between the LOW LEVEL INPUT jacks of
the REL and the le or right channel output of your preamplier. In some cases, these channels can be
combined with a “Y” cable or a dedicated SUB output.
Please consult your pre-amplier’s/integrated amplier’s manufacturer before connecng with a “Y” cable.
When connecng to a home cinema system where there is a .1/LFE channel output, connect a single RCA to RCA
or XLR to XLR cable between the sub output of the processor/receiver and the .1/LFE input jacks on the REL.
1 Posioning: The opmal posion for a single REL Serie T/x 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’s crossover to the longest distance in the room in order to produce
the longest, therefore lowest frequency, bass waves.
1a.Stereo Set-Up of Serie T/x: : (see page 11 through 12 for Stereo Set-Up procedure).When this step has
been completed, proceed to Number 2, immediately below.
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 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 at 50Hz on the crossover control, or slightly
higher for smaller speakers. At this point turn the HI/LO 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 canceling it.
