Operation Manual

When you have accomplished this task, plug all three units in and re-check your gain settings as the
cumulative effect of hooking all three up will usually result in, temporarily, excessive output. Work carefully
and methodically to reduce the settings on primary, then rear, and finally center channel RELs and in a few
minutes balance should be restored. However, the net result of all your tuning will be a sound that utterly
immerses the theater owner in a rich natural wash of bass that suffuses the room effortlessly, rather than
what is often experienced as too loud a bass balance pushing uncomfortably at the listener.
Running In
Care taken over running 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 an eventual higher potential
performance is assured.
Care and Polishing
The cabinets are best maintained by using a light automotive spray-on wax and a micro fiber cloth. (We use
a spray-on made by a company called Griot’s Garage™. While this may not be available in all markets, you
can use a similar product.) Take care not to spray the aluminum badge. Do not place objects, such as drinks
on top of your REL TZERO. Never use a dry cloth on this finish.
Technical
TZERO uses a very fast, gentle and transparent filter intended to allow excellent impulse response and a
natural sound. We refer to this circuit as Natural RollOff™. Most subs use slow, very steep filters that lend
an unnatural, machine-like quality to the sound. The TZERO employs a highly refined Class-D amplifier
which combines high performance and high efficiency. The TZERO includes an automatic power-saving
mode which ensures that, when not in use, the unit consumes as little power as possible. The driver is
simple, rugged and relatively light, and yet offers excellent self-damping so we are better able to
reproduce the nuance of music and preserve the explosiveness of transients. Finally, the cabinets, apart
from being physically beautiful, are like finely tuned instruments that are largely responsible
for the sonic
virtue with which the
TZERO
is imbued.
