Direct Energy HD Amplifier
New Power Amp Module
Both the main and amplifier
chassis are partially insulated,
providing the most stable earth
for each section. Together with
the separate construction, this
ensures high sound quality

separate components.
Insulated Dual Chassis
Advanced 3-D Space Frame Construction
In order to make the most of the Direct Energy HD Amplifier,
Pioneer developed an innovative power amp module. It puts the
power supply, power device and speaker terminals inside a
c o m p a c t u n i t t h a t i s o n e - t e n t h t h e s i z e o f p r e v i o u s
configurations. An optimised circuit layout and highest quality
parts ensure maximum power performance.
Ultra Rigid Separate Construction
Because the power amp module is

construction. The power amp

separated by a metal plate, so
they perform like two distinct
amplifiers. TAOC carbon cast
insulators effectively dampen
any vibrations.
For the SC-LX90 power amplifier,

the drawbacks typical of Class-D
amps. It effortlessly delivers

Power Amp Assign Selector
The Power Amp Assign Selector gives you extreme flexibility for
configuring your home theatre system. You can assign the 10
power amp channels in a variety of ways, including 9.2-ch full
surround, 7.2-ch plus multi-zone, 7.2-ch front bi-amp, 7.2-ch
speaker B, and 5.2-ch all bi-amp.
Isolated Power Supply Design
The SC-LX90 has an extremely sophisticated power supply
system, with separate transformers for the analogue and
digital circuitry. The digital circuits use high capacity DC/DC
capacitors, while the analogue circuits use low-noise series
pass regulators. The Direct Energy HD Amplifier has its own
Switching Mode Power Supply. This optimises the performance
of every circuit, for superior sound quality.

great sound, but where exactly do
you put the speakers? Precision
