Pioneer KRP-500P Direct Energy HD Amplifier, Insulated Dual Chassis, Isolated Power Supply Design

Direct Energy HD Amplifier

For the SC-LX90 power amplifier, Pioneer collaborated with ICEPower to develop an entirely new Direct Energy HD (High Fidelity Class-D) Amplifier. This amp uses multiple feedback technology to eliminate power supply interference and load fluctuation effects, overcoming the drawbacks typical of Class-D amps. It effortlessly delivers 140W x 10 of ultra-pure power for the finest listening experience.

Insulated Dual Chassis

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 equivalent to that of two separate components.

Advanced 3-D Space Frame Construction

This internal construction method uses 1.6mm thick steel plates to isolate the power s u p p l y , p o w e r a m p , analogue/digital circuitry and video circuitry. Because there can be no interference among these elements, each can perform to its optimum ability.

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.

New Power Amp Module

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 compact unit that is one - tenth the size of previous configurations. An optimised circuit layout and highest quality parts ensure maximum power performance.

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.

Ultra Rigid Separate Construction

Because the power amp module is s o c o m p a c t , i t a l l o w s a n i n n o v a t i v e t w o - l a y e r construction. The power amp a n d p r e a m p s e c t i o n s a r e separated by a metal plate, so they perform like two distinct amplifiers. TAOC carbon cast insulators effectively dampen any vibrations.

Precision Distance

Amulti-speaker system promises great sound, but where exactly do you put the speakers? Precision Distance tells you. This unique f e a t u r e a n a l y s e s s p e a k e r p o s i t i o n s a n d g i v e s y o u a n on-screen display of how to adjust them. You can get the same optimum speaker configuration that a skilled installer would give you.
