switch, using the phase switch, from “0” to “180” phase positions. Again, whichever position is loudest or
fullest is the correct position. That is, when the position is working in harmony with your main speakers,
reinforcing bass, not canceling it.
Crossover and Level Settings:
To determine the crossover point, take the volume of the REL (using the Level control) all the way down,
and put the crossover to 1/4 of the rotation. At this point, bring the REL’s volume back up slowly to the
point where you have achieved a subtle balance, i.e. the point at which you can just hear the HT/MKII even
with the main speakers playing. First, bring the crossover point up until it is obviously too high; now gently
reduce frequency to the appropriate setting. For all intents and purposes, this is the correct crossover point.
Once this stage has been reached, subtle changes to volume and crossover may be accomplished to provide
the last bit of complete and seamless integration. With that, set-up is complete
Hint: There may be a tendency to set the crossover point too high and the volume of the Sub-Bass System
too low when first learning how to integrate a REL with the system, the fear being one of overwhelming the
main speakers with bass. In making this common error, the resulting set-up will be lacking in bass depth and
dynamics. The proper crossover point and volume setting will increase overall dynamics, allow for extended
bass frequencies, and improve soundstage properties. Note, volume adjustments may need to be made to
offset the effects of crossover changes. In general, when selecting a lower crossover point, more volume may
need to be applied. Higher crossover frequencies will generally necessitate less gain
Running In
Care taken during run in will be rewarded by many years of pleasurable use. Both the electronics and the
drive unit will benefit from an initial period of carefully controlled use. Possible damage may be sustained
by running in the unit at too high a volume setting over an extended period. On the other hand, by taking a
little care over this initial period, about 24 hours of actual use, a longer life with a higher potential eventual
performance is assured.
Care and Polishing
The cabinets are best maintained by using only a damp cloth on the vinyl. For the top, please use
automobile polish made by reputable manufacturers. Our favorites are those made by Meguiars and
Mother’s. If objects are to be placed upon the top, it is advisable to use a small mat to protect the surface
and to avoid the risk of rattles.
