...oh btw, i have recently bought the EMI Power Line Tester from an MO and realized that when my airconditioner is not turned on, the reading shows 450mV there about. However, when my AC is turned on, with the compressor cut in, the reading is 1,500mV....Anybody got any ideas on how to reduce the noise injection into the power line when the AC is running?
... But just curious will the hum isolation module affect the sound quality?
