• Line Level Analog Inputs: Line level analog inputs on the SP-1 are switched using precision control relays. This signal path is entirely passive, and so introduces virtually no additional noise or distortion to the analog signal. The signal level and source impedance are determined solely by the source device.
  • Phono Input Impedance:
    MM: 47k Ohms
    MC: user selectable – 47, 100, 470, 1k Ohms
  • Gain:
    MM: 40 dB
    MC: 60 dB
  • Frequency Response:
    MM: RIAA + / – 0.12 dB, 20 Hz – 20 kHz
    MC: RIAA + / – 0.25 dB, 20 Hz – 20 kHz
  • Signal to Noise Ratio (S/N; A weighted):
    MM: > 88 dB
    MC: > 68 dB
  • THD:
    MM: <0.0075 % @ 1 kHz; < 0.03%, 20 Hz – 20 kHz
    MC: <0.006 % @ 1 kHz; < 0.08%, 20 Hz – 20 kHz
