THD+N | 0.001%, @ 1kHZ into 64Ω |
Total Harmonic Distortion + Noise is the percentage of output signal which is made up of frequencies added due to harmonics of the fundamental frequency and noise. By using low-noise input circuitry and Class A signal stages, Perreaux engineers have kept this figure to a minimum.
Frequency Response | 5Hz to 60kHz, +0dB |
Describes the frequency range where the amplitude or strength of the output signal deviates by no more than 0.25dB.
Signal to Noise Ratio (unweighted) | 105dB |
The ratio of desired signal to noise signals in the output. Headphone reproduction is susceptible to noise because of the nature of the environment to reveal every detail. This is why Perreaux engineers have designed the SXH2 to maintain a low noise floor.
Dynamic Headroom | >3.0dB |
This indicates the SXH2 can provide more than enough extra power to cope with the sharpest musical transients. Without adequate headroom, an amplifier can become unstable under clipping conditions. Perreaux amplifiers are intrinsically stable under all dynamic conditions.
