G) Repeat the above measurements for the right channel. Connect the oscillator
to the right analog input and the distortion analyzer to the right analog out-
put.
H) Disconnect the oscillator and THD analyzer from the 6300.
6. Test Digital Sample Rate Converter (Receiver).
A) Verify 6300 software controls are set to their default settings. (Refer to page
4-7.)
B) Be sure you are still in B

C) Navigate to S

D) Connect the digital source generator to the AES3 DIGITAL IN XLR connector of
the 6300.
E) Set the frequency of the digital source generator to 400 Hz and its output
level to 6 dB below full scale.
F) Set the word length of the digital source generator to 24-bit. In turn, set the
generator to emit 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz sample
rates. Listen to the analog outputs of the 6300 and verify that the output
sounds clean and glitch-free regardless of the source sample rate.
G) Leave the digital source generator connected to the 6300.
7. Test Digital Sample Rate Converter (Transmitter).
A) Connect an AES3 analyzer (like the Audio Precision System 2) to the 6300's
AES3 DIGITAL OUT 1.
B) Set the sample rate of the digital source generator to 48 kHz.
C) On the 6300, navigate to S
D) Change the 6300's D
