Digital I/O, Setup, and Utilities

Using two recorder tracks per channel, high-resolution digital audio can be 
recorded at the maximum wordlength of 24 bits. Recorder tracks 1 to 4 are 
used for the upper 16 bits, while tracks 5 to 8 are used for the lower 8 bits. 
In 24-bit Recording mode, a single slot can output up to four channels, 
which are selected on the DIGITAL I/O 5/5 page. See “Slot Output Select” 
on page 194. Slots 1 and 3 output bus signals 1 to 4, while slots 2 and 4 
output bus signals 5 to 8. Aux, stereo, and direct out signals can also be 
recorded in 24-bit mode. Output signals are split in two and fed to two 
recorder tracks. For example, bus out 1 is split and fed to recorder track 1 
(upper 16 bits) and track 5 (lower 8 bits). Bus out 2 feeds tracks 2 and 6. Bus 
out 3, tracks 3 and 7. And bus out 4, tracks 4 and 8.

For playback, track signals are automatically recombined and fed to the 
02R channels as shown in the following table.

As the table shows, in 24-bit Recording mode four MIC or TAPE channels 
for each slot cannot be used. So if all four slots are used for 24-bit recording 
the maximum number of slot inputs is reduced from 32 to 16. The 
recording mode can be set individually for each slot, however, and settings 
are stored in scene memories.

The following I/O cards can be used with 24-bit Recording mode: ADAT 
(CD8-AT), Tascam (CD8-TDII), Yamaha (CD8-Y), AES Single (CD8-AE-S), 
and AES Double (CD8-AE). The following I/O cards can be used with 
24-bit Recording mode: ADAT (CD8-AT), Tascam (CD8-TDII), Yamaha 
(CD8-Y), AES Single (CD8-AE-S), and AES Double (CD8-AE). The input 
and output configurations for analog I/O cards are not affected by the 
24-bit Recording mode settings.
