Apply 9.0 V DC and sine wave
(60 Hz, 500 mVrms) to VCC
terminal.
Measure amplitude of TP12,
TP13 and TP16 (vTP12 mVrms,
vTP13 mVrms, vTP16 mVrms).
RR1 W dB = 20 og (vTP12 / 500)
RR1 R dB = 20 og (vTP13 / 500)
RR1 L dB = 20 og (vTP16 / 500)

(a)
Input signal (100 Hz, sine wave)
to TP6 and TP8.
Increase amplitude of the input
signal, and measure THD of
TP13 and TP16.
Measure amplitude of TP13 and
TP16 when THD of the output is
1% (vDOUT R1 Vp-p, vOUT L1
Vp-p).
Input signal (10 kHz, sine wave)
to TP6 and TP8.
Increase amplitude of the input
signal, and measure THD of
TP13 and TP16.
Measure amplitude of TP13 and
TP16 when THD of the output is
1% (vDOUT R2 Vp-p, vDOUT L2
Vp-p).
Smaller value vDOUT R1 or
vDOUT R2 is vDOUT R. Smaller
value vDOUT L1 or vDOUT L2 is
vDOUT L.
Input signal (80 Hz, sine wave) to
TP6 and TP8.
Increase amplitude of the input
signal, and measure THD of
TP12.
Measure amplitude of TP12
when THD of the output is 1%
(vDOUT W Vp-p).
