Note *1.1ch Drive *2.All tests are measured using a constant-voltage supply unless otherwise specified. *3.The output noise voltage is peak value of an average-reading meter with a rms value scale(VTVM). A regulated AC supply(50Hz) should be used to eliminate the effects of AC primary line flicker noise. *4.Available time for load short-circuit and output noise voltage are measured using the specified transformer power supply.
