THEATER 7 XD - 7 Channel Power Amplifier
100 Watt Amplifier Featuring Krell iBias Technology
The amplifier design uses Krell Current Mode technology that is fully differential and discrete in the critical gain stages. This results in a highly linear and extended frequency response, well beyond the range of hearing, for smooth effortless highs and tight high impact bass.
The power supply consists of two 787VA toroidal transformers and 160,000uF of capacitance. This is shared among all the channels so all of that power is available to the channels with the most demand.
In real world conditions the left, right, and center channels require the lion’s share of the power so this gives the Theater 7 a more effective power supply than other amplifiers that have smaller dedicated power supplies for each channel.
