9. Noise Interference
- U(F) = extraneous voltage non-weighted with B = 22 Hz ... 22 kHz, effective value (IEC 268-1)
- U(G) = noise voltage, frequency-weighting filter according to CCIR-468-3, quasi peak-weighted (IEC 268-1)
- U(A) = interference voltage A-weighted, dB(A), effective value (IEC 268-1)
- S/N ratio ref. to max. output voltage at 4 ohms = 55.1 V (+37 dBu) and interference voltage A-weighted.
