Current Mode gain stages from input to output, and Current Audio Signal Transmission (CAST) receivers and transmitters. Utilizing these powerful technolo- gies, the Phantom conveys the complete range of timbre and dynamics that com- prise the foundation musical performance. Typical of our latest preamplifier designs, the Phantom preamplifier includes a thoughtful suite of menu options and can be customized for the greatest ease of operation. - Page 6 Circuitry Highlights The Phantom preamplifier is a dual monaural circuit design with the left and right channels afforded their own power supply regulation and individual full chassis sized boards. All signal gain is realized in surface mount topology using propri- etary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs.

Page 7: Revolutionary Krell Cast Technology
Capable of delivering current and voltage swing for any musical event, the Phantom power supply is gentle on AC require- ments when not in use. A new eco-friendly design reduces standby power draw to 2W. -
Page 8: Section One: Phantom Features And Technology
Here is how a CAST audio system works. Internally, each CAST source transfers, or amplifies, current using Krell Current Mode circuitry. This current signal is then output using CAST circuitry. When the signal is received by a CAST input, Krell Current Mode circuitry again takes over until the signal reaches the loudspeaker. - Page 9 The goal for CAST is the same company goal used for all Krell products. Krell strives for the delivery of the best performance of a musical event for you, using the full expres-...
