Product Overview
Little amp that could... and does. Repeatedly.
The DRA-1 Differential Reference® Amplifier wakes your speakers with clean vocals, tight bass, and smooth sound at any volume. Built into a compact chassis that stacks to keep your system small, its Hypex NCOREx solution is transparent and efficient, with high-current for power delivery without glare. You get 100 watts x 2 at 8 ohms or 130 watts x 2 at 4 ohms. Bridge both channels into one for 400 watts at 4 ohms. Noise and distortion sit far below the music: signal-to-noise ratio over 115 dB and total harmonic distortion plus noise and low kevels is 0.0008%.
