NOISE INTERFERENCE
- U(F) = external voltage un-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)
- Signal-to-noise ratio referenced to a nominal output voltage of 69.3 V (1200W/4ohms)
- HI/LO-CUT ON, GND LIFT = GROUNDED
