Jitter Measurement
· Connect the STEREO OUT DIGITAL A terminal to DSA1.
· Set the Fs to 48 kHz and 44.1 kHz with the test program and measure the jitter at DSA1.
3-8.
Ramp Voltage Measurement
· Measure the voltage between Pin 3 and Pin 4 at four locations on the rear panel.
· Measure the voltage when the RAMP DIMMER control is MAX and MIN.
3-9.
Fan Operation Check
· Check that the fan rotates while the power is on.
· Listen to the noise from the fan to verify that the FAN switch changes the rotation rate.
