Best Signal-to-Noise Contender In Its Class

Total Harmonic Distortion (THD+N) vs. Frequency

  • Uniquely, the Power Pack distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion. - < 0.03% THD+N @ 1W, 1% THD+N @ rated power.
