Scotch #206
2. Reference recording level: meter 0dB level (NAB standard reference
level)
3. Reference signal: 1,000Hz
4. Wow & Flutter: at 3,000Hz weighted RMS
5. Frequency response: measured at -20dB level (19cm/s)
6. Signal-to-Noise ratio: measured at +6dB level (reference recording
level)
7. Total Harmonic Distortion: measured at reference recording level
8. Channel separation: measured at reference recording level
9. Channel crosstalk: measured at 0dB level(reference recording level )
10. Sensitivity: Input level (mV) for reference recording measured with
input (recording) level control set at maximum position.
11. Maximum allowable input level: measured at the point where the output
signal wave is clipped while gradually turning the input control.
12. Reference output level: meter 0dB level.
