Krell Chorus 7200 XD 200 Watt 7 Channel Power Amplifier

Krell iBias Class A amplifiers are the first to deliver the rich musicality of Class A amplifiers, the uncompromised dynamics of classic Krell amplifiers, with much greater efficiency than traditional Class A amplifiers.

Circuitry Highlights

Krell iBias Class A technology allows their latest amplifiers to run in full Class A mode to full power while minimizing heat generation. All signal gain is realized in the current domain using discrete, proprietary, multiple-output current mirrors with extraordinary open loop linearity. There are no generic integrated circuits or op amps used anywhere. 

Power Supply Highlights

Four 700VA toroidal transformers feed amplifier modules that include the audio circuitry, rectifier, and power supply filtering mounted to an individual heat sink. This design shortens the electrical path from the power supply to the output transistors, reducing the overall impedance and allowing the circuit to respond faster and control the speakers better and more accurately.

Krell Foundation 4K Ultra HD Home Theater Processor

The Foundation 4K UHD Surround Sound Home Theater Processor couples award winning Krell preamplifier circuitry to the latest in HDMI technology to create the centerpiece of a high performance home theater system. The Foundation 4K UHD adds HDMI 2.0 and HDCP 2.2 technology to the award winning Foundation processor. From decoding the latest lossless audio formats, extensive digital switching, 3DTV pass-through, and more, the Foundation 4K UHD is fully compliant with the digital age. The 7.1-channel processor also features balanced audio outputs, automatic setup and room EQ, and Krell’s legendary robust hardware. A slim form factor exudes the Krell aesthetic, while allowing placement in smaller equipment racks.
