The fans used are specifically chosen for quiet operation, and operate at the speed required to maintain the ideal internal temperature. This convenient form factor is made possible through thermostatically controlled ventilation fans. Unlike traditional Class A amplifiers, iBias Class A amps have a compact design that allows rack-mounting, making them ideal for custom installation as well as traditional audiophile systems. 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 even better and more accurately. Depending on the model, up to four toroidal transformers feed amplifier modules that include the audio circuitry, rectifier, and power supply filtering mounted to an individual heat sink. The power supplies of our Krell iBias Class A amplifiers have been optimized for use with the iBias circuit. Power supply technology has always been an important contributor to the Krell sound. Our revolutionary, patent pending circuit delivers true Class A operation without the excessive heat and wasted energy of conventional designs вЂ“ Learn more. KrellвЂ™s history is rich with breakthrough Class A amplifiers that have helped build the Krell legacy of offering the best sounding amplifiers available. This lower output impedance exerts more control over the speaker drivers, and damps out unwanted vibrational modes-allowing a more accurate reproduction of the original signal. This affects the amplifierвЂ™s stability and transient response, so each stage prior to the output stage had to be re-tuned to work optimally with the lower output impedance. It was no simple matter merely lowering the output impedance. When applying this technique to our existing line of amplifiers, the improvement was so substantial, it deserved its own, unique designation-XD. During the development of the K-300i Integrated Amplifier we discovered substantial sonic improvements by lowering the output impedance below traditional norms. XD is a classic example of KrellвЂ™s continuous R&D efforts reaping benefits across multiple product lines.

KrellвЂ™s XD (Xtended Dynamics, Dimensionality & Detail) upgrade for the iBias amplifiers takes an already great sounding amplifier and raises its performance to the next level. In real world conditions the left, right, and center channels require the lionвЂ™s share of the power, thus giving the Theater 7 a more effective power supply than other amplifiers that have smaller dedicated power supplies for each channel. This is shared among all the channels so all of that power is available to the channels with the most demand. The power supply consists of two 787VA toroidal transformers and 160,000uF of capacitance. 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 Theater 7 XD amplifier design uses Krell Current Mode technology-fully differential and discrete in the critical gain stages. вЂњThe New XD amplifiers haveвЂ¦ warmthвЂ¦ tonal saturationвЂ¦ a level of bass slam that made Krell famous.вЂќ They easily cut through background noise such as chatter and command attention from your audience.Krell Theater 7 XD Multi-Channel Amplifier Even though they are more of a traditional form of communication, these multi channel power amplifier systems continue to play a vital role in addressing groups of people. They give you a quick way to address everyone at a given location.
