SPECIAL DESIGN FEATURES
MACHINED ALUMINUM CHASSIS:
The preamplifier circuitry is housed inside twin
ultra-low resonance, structurally rigid chassis precision-machined from solid
ingots of aircraft grade 6061-T6 aluminum, completely sealed for trouble-free
operation, yield maximum electrical/EMI/RF isolation.
FUNCTIONAL ISOLATION:
Power supplies and microprocessor-based system
control circuits confined inside Control Chassis. Sensitive audio circuits isolated
in separate Audio Chassis. Left and right channel circuits are further isolated into
individual milled aluminum pockets in a true dual mono design for ultimate RF
and EMI shielding.
FREE OF INTERNAL SIGNAL POLLUTION:
Control subsystem taken completely offline
after each command execution to maximize sound purity. All signal switching
relays are “latching” type which only draw current for a few milliseconds during
the switching event then revert to a no current “off” state.
ADVANCED DC OPERATIONS:
NiMH field replaceable high capacity, industrial
grade, rechargeable batteries provide the ultimate clean power source and
absolute isolation from the power grid. AC power supply is taken offline during
DC battery-based operations to isolate the
CRITERION PREAMPLIFIER
completely
from residual mains grunge.
MULTI-REGULATED AC SMPS:
High speed regulated, low noise switch mode power
supply (SMPS) developed for aerospace applications incorporates passive power
factor correction (PFC) for sonic performance so pure and musical that is virtually
invariant to different quality power cords. Power supply radiation is isolated by
locating the power supply in it’s own milled pocket.
AUTOMATIC WORLDWIDE OPERATIONS:
Auto-sensing and auto-ranging SMPS
provides optimum performance at any world-wide mains operating voltage
between 85V and 265V.
CERAMIC CIRCUIT BOARDS:
All audio circuits are implemented on military-grade,
multilayer, low dielectric constant, Rogers™
ceramic
circuit board substrate for
extremely low energy retention and absorption. Large low impedance ground
planes for extended internal star-grounding. Newly developed ceramic capacitors
replace conventional electrolytic type, resulting in power supply noise decoupling
improvements by an order of magnitude (10X).
