OPERATION & PERFORMANCE
OPERATION & PERFORMANCE
SUPERB CLARITY WITH C.R.I.S.T.A.L.® AUDIOPHILE TECHNOLOGY
All GECKO® GENESIS ELEGANCE Series amplifiers use refined multi-stage C.R.I.S.T.A.L.® Audiophile
Class-H technology for precise audio reproduction (step-up from previous 3-tier C.R.I.S.T.A.L.® Audiophile
Class H design). The new multi-stage C.R.I.S.T.A.L.® Audiophile Class-H technology allows wider frequency
bandwidth to be processed in numerous bands of “frequency cells” more efficiently while maintaining the
desired RC time constants. The result – superb audiophile clarity and an energy efficient system with lots of
headroom.
THERMAL PROTECTION WITH ULTRA QUIET COOLING (UQC) SYSTEM
All GECKO® GENESIS ELEGANCE Series amplifiers use forced-air cooling system to maintain a low, even
operating temperature. Drawn in by dual 45 cubic feet-per-minute (CFM) fans, cool air flows through the front
cooling vents, then exhausts through the evenly-layout copper heat sinks (dissipating power transistor heat)
located at the rear vents. The “intelligent” variable-speed DC fans are controlled by Ultra Quiet Cooling
(UQC) heat sink temperature-sensing circuits. When the amplifier is turned on, the fans briefly “rev up” for
approximately 6 seconds, then slow to an idle; this indicates that the temperature sensing circuits are
operating normally. The fan speed increases only as required by heat sink temperatures, keeping fan noise
to a minimum. Under extreme thermal load, the fans will force a very large volume of air through the heat
sinks. If the heat sinks surpass the maximum allowed temperature, the Ultra Quiet Cooling (UQC) sensing
circuit will open the output relay, disconnecting the load from that channel (TEM LED indicator illuminates). If
the power transformer overheats, another Ultra Quiet Cooling (UQC) sensing circuit opens both channel
output relays until the transformer cools to a safe temperature.
SHORT CIRCUIT PROTECTION WITH IMPEDANCE SENSING CIRCUITRY (ISC)
If an output is shorted (i.e. defective speakers or crossed speaker wires) the Impedance Sensing Circuitry
(ISC) and thermal circuits will automatically protect the amplifier. The ISC circuit senses the short circuit as
an extremely stressful load condition and attenuates the signal, protecting the channel’s output transistors
from over-current stress. If the short circuit remains, the load will be disconnected by the thermal protection
circuitry (output relay opens). PRO LED indicator illuminates.
DC VOLTAGE PROTECTION
If an amplifier channel detects DC voltage at its output terminals, the output relay will immediately open to
prevent speaker damage. PRO LED indicator illuminates.
CLIP PROTECTION WITH VOLTAGE PEAK LIMITER (VPL)
The Voltage Peak Limiter (VPL) provides optimum peak voltage settings for each channel automatically. At
the amplifier’s full power limit, or clipping point, VPL will be activated. This is indicated by illumination of the
VPL / CLIP LED. The channel gain is automatically reduced, protecting the speakers from potential damage
from the high power, continuous square waves that would otherwise be produced. The circuit is virtually
transparent in operation and full signal bandwidth is maintained.
