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 dis-

tortion 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.
