The Direct Energy HD Amplifier has further evolved as Digital Class
D
3
Amplifier to meet the needs of the latest HD content. With our
MOSFET, the Direct Power FET, a simple, high-power solution is
provided to fully enjoy today’s AV entertainment. This year, the
digital circuit power supply has been redesigned on all models, to
provide a clean electric current with reduced noise.
High-Power Simultaneous Multi-Channel Drive
With class AB amplifiers, driving all channels in full power is only
possible for a short time, at around 300 W to 400 W power output.
Pioneer’s Digital Class D
3
Amplifier has plenty of allowance to
simultaneously drive 9 channels at 760 W (SC-85) to 850 W (SC-89)
power output, letting you fully enjoy dynamic scenes.
Eco-Friendly
The power consumption of the Digital Class D
3
Amplifier is
exceedingly lower than analog amplifiers — letting you save
energy without compromising performance.
High Efficiency
The Digital Class D
3
Amplifier has been designed with a simple
structure to take a straight signal path, resulting in improved
sound quality.
Low Heat Generation
The simple form of the Direct Power FET has the advantage of
improved thermal characteristics. In addition to the upper-side
heat dissipation from the heat sink, the circuit board’s heat
radiation feature is also utilized for downward heat dissipation,
providing efficient cooling for a superior performance.
Quick-Response Sound
The Direct Power FET is directly connected to the print circuit
board without any wiring. This simple structure maximizes
audio performance by reduced noise and improved switching,
offering a quick-responding sound, perfect for digital content
playback.
Improved Circuit Design
On the top two models, dedicated ICs are lavishly used on the
circuit in pursuit of ideal sound. The operational amplifier IC for
processing small signal is set apart from the amplifying section
to prevent mutual interference. This allows clear signal to be
transmitted to the Direct Power FET. As for the SC-85/SC-82/
SC-81, they adopt a compact integrated IC with space merit. The
directly coupled IC reduces signal loss and provides precise
signal transmission.
