Definitions and conditions
Input and output voltages are RMS values for a sine signal
and 1 kHz unless stated otherwise.
Tone controls in neutral position unless stated otherwise.
Min. input voltage: Input voltage for nominal output
voltage at line out with gain and master fully clockwise.
Max. input voltage: Permissible input voltage that does not
cause distortion more than the rated THD + N (assuming
suitable control settings).
Signal-to-noise ratio (SNR): Ratio of nominal output voltage
to noise voltage at line out, at specified gain setting,
master fully clockwise, input shorted, 20 Hz…20 kHz.
Note: The SNR found at line out may be less than the SNRs
specified for the channels because both channels
contribute to the output noise.
Residual noise: Noise voltage at an output when all gain
and level settings are minimal.
THD + N: Total harmonic dist noise for nominal
output voltage at line out
Specifications and appearance subject to change without
notice.
