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. (Our
favorites are those made by Meguiars and Mother’s. While these may not be available in all markets, you
can use a similar product.) Take care not to spray the aluminium badge. Do not place objects, such as
drinks on top of your REL TZERO MKIII. Never use a dry cloth on this finish.
Technical
TZERO MKIII 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 MKIII employs a highly refined Class-D
amplifier which combines high performance and high efficiency. The TZERO MKIII 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 MKIII
is imbued.
Power Saving Efficiency
All REL Sub-Bass Systems are designed for maximum power efficiency, both when passing a signal through
to its resultant output sound into the room and also when silent.
In addition to the low power draw exhibited by all REL models, the TZERO MKIII also features an automatic
standby mode that is enabled when the power mode switch on the rear of the unit is set to the “STANDBY”
position. In this mode, the input signal is constantly monitored for activity (audio information). If no audio
information is detected over a period of fifteen minutes, the unit will enter a low power standby mode in
which less than 0.5 watt of power is consumed. When input signal activity is detected, the unit resumes
