; 8 OHM @ 1KHZ, 5%THD (LPF 20KHz) (ONE CH)
*LIMITER (
CH LEVEL VR & MASTER VR NORMAL)
(AMP OUTPUT)
RATED Ouput,Again add 20dBm,Amp Output No Clipping
*FREQUENCY RESPONSE
8ohm load,Output 1W
Remark:
1. If check we want to output test signal from the analyzer(VP-7723B),please parallel a 600 ohm Load from the output
signal.
2.. The low pass filter should be 20KHz while testing the part of Amp.
