TEST METHOD
40 40 72 00 72 40 * 10 (a) l Input signal (1 kHz, 500 mVrms, sine
wave) to TP6 and TP8
l Measure amplitude of TP13 and
TP16 (v13s mVrms, v16s mVrms).
l Connect TP6 and TP8 to GND.
l Measure amplitude of TP13 and
TP16 (v13n mVrms, v16n mVrms).
l SN R dB = 20 âog (v13s / v13n)
SN L dB = 20 âog (v16s / v16n)
l Input signal (80 Hz, 125 mVrms, sine
wave) to TP6 and TP8.
