Step 3 - Setting a Conversion
do this: If you need bit-for-bit operation in a different output format, proceed to the
Format Conversion section.
do this: If you want to change the sample rate or the word length or process the data in
some other way, proceed to the Sample Rate Conversion section.

Figure 3 – Pure Format Conversion
do this: Press the ←
←←
← button, scroll down to Format Conversion , press the →
→→
→ button
and press the Set button. This sets Pure Format Conversion to On and
disables the Sample Rate Conversion menu.
do this: If the “Fs In not Fs Out” information box appears on the display, press the Set
button to make the Output Sample Rate match the Input Sample Rate.
do this: Scroll down the Format Conversion menu to Output Mode and press the →

→
button. The cursor should be beside Normal. Choose one of the settings from
the following list, scroll to it and press Set:
• Normal. The Input & Output Sample Rate must not be higher than
96kS/s. Bit-for-bit data will be available on all of the AES, SPDIF or SDIF-2
outputs.
• Dual AES. The Input & Output Sample Rate must be 88.2, 96, 176.4 or
192kS/s. Dual AES bit-for-bit data will be available on the AES 1 / AES 2
output pair and the AES 3 / AES 4 output pair. Do not use the other outputs.
• Quad AES. The Input & Output Sample Rate must be 176.4 or 192kS/s.
Quad AES bit-for-bit data will be available on the AES 1, AES 2, AES 3 and
AES 4 output group. Do not use the other outputs.
• DSD SDIF-2. The Audio Input Select setting must be DSD or DSD Quad.
DSD SDIF-2 bit-for-bit data will be available from the DSD/SDIF outputs
(lower block) and DSD Quad data from the AES 1, AES 2, AES 3 and AES
4 output group. Do not use the other outputs.
• DSD SDIF-3. The Audio Input Select setting must be DSD or DSD Quad.
DSD SDIF-3 bit-for-bit data will be available from the DSD/SDIF outputs
(lower block) and DSD Quad data from the AES 1, AES 2, AES 3 and AES
4 output group. Do not use the other outputs.
do this: Proceed to Step 4.
