Gryphon Colosseum - Manual (Page 14)

extreme low power consumption of
Class A/B, or even the low power
consumption of "auto-biasing" sys-
tems, it does offer significantly
lower power consumption without
sacrifice or compromise of even a
fraction of its PURE CLASS A per-
formance.
The Colosseum user who do not
own a Gryphon preamplifier can
access the progammable bias sys-
tem manually.
Protection
When DC or HF is detected at the
input, the amplifier mutes until the
error condition is corrected.
The output signal is constantly com-
pared to the input, so that, in the
presence of a difference which
exceeds predetermined limits (typi-
cally a short circuit condition), the
amplifier mutes until the error con-
dition has been corrected. Heatsink
temperature is constantly moni-
tored by a thermistor. In the event of
overheating (temperature in excess
of 82° C), the amplifier will turn-off
and go in stand-by mode. Normal
operation will resume when a safe
operating temperature is reached.
At temperatures above 100°, the
amplifier will turn off and can not be
turned on again before temperature
is below 50°.
Exterior
The Top and base plate is
machined from a solid 40 mm black
acrylic block. A VFD display pro-
vides continuous information on
amplifier status. The amplifier is
“floating” inside the oval cover, the
unique architecture of the
Colosseum provides a new level of
logic amplifier thinking, allowing the
componets the best possible work-
space and conditions. The double
transformers are suspended and
radiation is controlled to prevent
them from intruding other compo-
nents. The decoupled curved side-
panels are purely cosmetic and are
not any expression of how the
amplifier is mechanically ridgid
ordampened. - You don´t kick the
tire of a Ferrari to judge the quality
of the design...
