The power amplifier is the final component in the signal chain before the loudspeakers. It is the workhorse of a hi-fi system. It takes the low-level signal from the pre-amplifier and converts it to a powerful signal to drive the loudspeakers. It has a low-level input to receive the signal from the preamplifier, and terminals for connecting loudspeaker cables.

Because of the power amplifier's unique function, it differs from other components in size, weight and use. High-quality power amplifiers are usually large and heavy. Moreover, the power amplifier is the component you don't need to touch and adjust. Consequently, power amplifiers are often placed on the floor near the loudspeakers rather than in an equipment rack.

STEREO POWER AMPLIFIER:
A power amplifier with two audio channels (left and right) in one chassis.

MONOBLOCK POWER AMPLIFIER:
A power amplifier with only one audio channel per chassis. Two monoblocks are required for stereo reproduction.

Mono Amplifiers

Krell's New XD Technology
Krell’s “XD” (Xtended Dynamics, Xtended Dimensionality, Xtended Detail) upgrade for the iBias amplifiers takes an already great sounding amplifier and raises its performance to the next level. “XD” is a classic example of Krell’s continuous R & D efforts reaping benefits across multiple product lines. During the development of the K-300i Integrated Amplifier we discovered substantial sonic improvements by lowering the output impedance belowtraditional norms. So we applied this technique to our existing line of amplifiers and the improvement was so substantial that it required a unique designation, hence, “XD.”

Pro-Ject Power Box RS Amp
Pro-Ject Power Box RS Amp
Linear power supply consists of a big toroidal transformer with shielding between primary and secondary winding which acts as an isolation transformer and avoids penetration of interferences from mains into amplifier. This transformer has a big power reserve, compared to a standard power adaptor. It has very low output impedance and in combination with large filtration capability it can easily manage required power of one stereo amplifier or two mono amplifiers. Advice: To avoid magnetic interference do not stack amplifier and Power Box RS Amp!
