The large power supply improves noise rejection and renders the Illusion II impervious to all but the most severe AC voltage power fluctuations. A new eco-friendly standby mode reduces power consumption to 2W. - - - - 1 AES/EBU via XLR connectors digital input 2 coaxial via RCA connectors digital input 2 optical via Toslink connectors digital input - -1 RS-232 input via 9-pin D-subminiature c onnector - - 1 Headphone output via 3 -conductor 6.35 mm (1/4 in) connector Digital Module Highlights The digital module supports up to 24 bit/192kHz LPCM. All digital signals are fed to an ESS Sabre DAC and then sent to Krells Current Mode, discrete, balanced analog circuitry. Circuitry Highlights The Illusion II preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple- output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero feedback, balanced, Krell Current Mode design, the Illusion II shares the same design philosophy as its bigger brother, the flagship Illusion preamplifier. Negative feedback is not used anywhere in the preamp, nor is it necessary. Open-loop distortion is typically less than 0.003%. The volume control is realized with a balanced resistor ladder - bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting. The headphone circuitry is identical to the main circuitry, offering private listening with the same performance as speaker playback. - - - - - - - - - - - - - - - - DESIGN SPECIFICATION HIGHLIGHTS Krell ®is a registered trademark of Krell Industries, LLC., and is restricted for use by Krell Industries LLC., its subsidiaries, and authorized agents.
