CAST and other key terms used in this reference. Circuity highlights Sharing the same audio circuitry as its bigger brother, the Phantom II 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.
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.
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-...
CAST and Evolution CAST Krell Current Audio Signal Transmission, or CAST, is a proprietary Krell circuit tech- nology for connecting analog components, transmitting the audio waveform between components in the current domain rather than in the voltage domain. The...

This unique technology provides the component with exceptional speed, and a wide bandwidth.
