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.

Elac DPA-1-M (DPA1M) Mono Amplifier
Elac DPA-1-M (DPA1M) Mono Amplifier
DPA-1M Monoblock Hybrid Digital Power Amplifier

The DPA-1M Digital Power Amplifier doubles up on the DPA-1’s almost magical combination of power, musicality and efficiency. Even though it’s just 10.5 inches wide, the DPA-1M conjures up an incredible 325 watts per channel into 8 ohms. Because it’s a monoblock, power is doubled and the left and right channels can hit full output and maximum dynamics without impacting the performance of the other channel. Hearing this tiny, cool-running amp produce such incredible dynamics is almost as dazzling watching a wizard change a rabbit into a horse. But it’s not magic, just a masterful combination of a Class A analog input stage with a high-efficiency Class D output stage.

DPA-1 Stereo Hybrid Digital Power Amplifier:

The DPA-1 Digital Power Amplifier was created to perform not just in today’s stereo systems, but in tomorrow’s systems, too. The core of the DPA-1 is a wizardly circuit topology that combines the musicality of traditional Class A and Class AB amps with the power, dynamics and efficiency of the latest Class D designs. From a chassis just 10.5 inches wide, the DPA-1 delivers 125 watts per channel into 8 ohms and 200 watts per channel into 4 ohms, plenty enough power even for the largest tower speakers. It might seem like magic, but it’s just solid engineering.
