KRELL’s new KMA-i800 class-A Mono amplifier
RRP @ NZ$139,995/pr
DESCRIPTION
Krell’s NEW KMA-i800 is a “state-of-the-art” class-A 800watt monoblock amplifier. It incorporates Krell’s most advanced circuit topologies and Krell’s proprietary technologies iBias, XD, and Sym-Max. This gives the KMA-i800 an organic, spacious and detailed presentation along with the rock-solid bottom end and effortlessness that Krell is known for.
DESIGN HIGHLIGHTS
iBias - iBias enables the KMA-i800 to operate in Class A up to its full rated power of 800 watts with absolute accuracy but without the heat produced by a traditional Class A design
XD - XD is a technique for lowering the amplifier’s output impedance. This results in better control over the speaker drivers which improves musical dynamics, depth, and dimensionality. It is very dependent on maintaining thermal equilibrium in the output stage so that all the output transistors are contributing equally to the signal output.
SymMax - SymMax is short for “Symmetry Maximisation.” The circuitry in the KMA-i800 is differential, meaning that there is a positive half and a negative half.
Power - The heart of any power amplifier is the power supply. The KMA-i800 has a massive power supply consisting of a 5400VA transformer and 188,000uF of filter capacitance. Delivering this power to the output circuit is a combination of gold-plated circuit boards and silver-plated sold copper buss bars with a very short physical path for extremely low impedance
Circuitry - The KMA-i800 uses Krell Current-Mode circuitry with advanced current mirroring that is balanced, differential, and direct-coupled. Each stage is independently tuned and matched to the previous stage for optimal operation
Control and Protection - The KMA-i800 is microprocessor controlled and has Ethernet connectivity and a 12VDC trigger input for easy connection to a home controller. The Ethernet connection allows access to the KMA-i800 web page for status information and control. The KMA-i800 is protected against high DC on the outputs, output short circuit conditions, and power brown outs. The protection operation is conveniently indicated on the front panel status lights and the web page
