(2) BNC
· Connect AD824 word clock out and DA824 word clock in.
· Insert MY8-AE card into the slot and connect to DSA1 via the D-sub-cannon converter box.
· Set AD824 word clock settings to BNC.
· Set AD824 word clock settings to 44.1 kHz and 48 kHz.
2-6
Fs operating range
· Connect the oscillator to AD824 word clock in.
· Set AD824 word clock settings to BNC.
(1) Fs=50.88 kHz (48 kHz+6 %)
· Set the oscillator to 50.88 kHz.
· Conduct a listening test for one minute to check that there is no noise.
(2) Fs=39.69 kHz (44.1 kHz-10 %)
· Set the oscillator to 39.69 kHz.
· Make the same input as 2-6 (1) and confirm that the same output level is attained. Or, conduct a listening test for one minute
to check that there is no noise.
