Meets the Standards of Hi-Fi Audio

THD+N (1kHz 0dB, No load)

THD + Noise (Distortion) over the THD + Noise signal rate, less distortion is heard. The AK10 achieves a 0.008% distortion signal rate.

Signal to Noise Ratio (1kHz 0dB, No load)

SNR (Signal to Noise Ratio) As the signal-to-noise ratio increases, the clearer the sound becomes. AK10 signal-to-noise specification is 110dB.

Crosstalk (1kHz 0dB, No load)

CROSSTALK The higher the number in the crosstalk specification, the higher the isolation in the Left/Right channels develops. The AK10 has a crosstalk specification of -106dB.

Frequency Response (1kHz 0dB, No load)

Frequency Response The frequency response specification of +0.02 to -0.02 in the AK10 provides a clear sound from Bass to Treble.
