Feed-Forward Error Correction

Don't look back, the future is here!

Benchmark's AHB2 power amplifier has a unique feedforward error correction system that cancels distortion before it reaches the speaker terminals. In contrast, global feedback systems attempt to correct the distortion after it reaches the speaker terminals.

Feed-forward correction is fast, precise, and inherently stable.

Benchmark's AHB2 blends feedback with feed-forward correction to leverage the best characteristics of each.

Listen to Gene and John as they discuss this revolutionary technology.

• How does the feed-forward system know what correction to send?
• Does it predict the future?
• What makes feedback unstable when driving capacitive loads?
• Why is feed-forward stable when driving capacitive loads?

Take a few minutes to learn how feed-forward error correction works:

• Watch as John provides an easy-to-understand analogy for feed-forward error correction.
• Join the discussion.
• We reserve the right to limit negative feedback.

The AHB2 - A Radical Approach to Audio Power Amplification

Benchmark's AHB2 Power Amplifier is radically different from every other audio power amplifier on the market. It delivers the lowest distortion and lowest noise of any commercially available power amplifier. The THD+N and SNR specifications are 20 dB better than many high-end hi-fi power amplifiers. The unique high-efficiency design delivers hundreds of watts from a relatively small, passively cooled chassis.

Benchmark's lead Engineer, John Siau, will take us on a deep dive into the AHB2. You may be shocked by what is inside!
