system sampling rate , from wherever it is derived, or sample rate conversion must be
enabled.
•
The digital outputs are at the system sampling rate , and all analog to digital and
digital to analog conversion is done at the system sampling rate .
S/P DIF
The digital inputs 1/2 are received at either the
AES/EBU 1/2 input jack or the S/P DIF 1/2 input
jack. To select between the two, use the
DIN 1/2
parameter on the "bottom"
inputs
menu page in the
SETUP
area.
The digital outputs 1/2 are sent out at both the
AES/EBU 1/2 output jack and the S/P DIF 1/2
output jack. To select between the two
formats , use the
DOUT 1/2
parameter on the "bottom"
format
menu
page in the
SETUP
area. To be clear, signals will be present at both the AES/EBU 1/2
output and the S/P DIF 1/2 output, but they can only be one format .
S/P DIF
selects a
"consumer" format while
AES/EBU
selects a "professional" format. Use the
AES/EBU
format unless you have a compelling reason to do otherwise.
Note: The digital inputs 1/2 need not be assigned to the same protocol as the digital outputs 1/2. In other
words, digital inputs 1/2 can be received at the AES/EBU 1/2 input jack and digital outputs 1/2 can be sent
via the S/P DIF protocol, or vice-versa.
Similarly, on the H8000FW, S/P DIF inputs 3/4 can be used in place of AES 11/12. Their protocols are fixed.

See
DIN 11/12 allows the choice of either AES/EBU or S/P DIF for AES11/12.

ATES
The H8000FW can operate over a range of sampling rates, from 32kHz to 100kHz. Because the
higher sampling rates demand more of the signal processing resources, some large presets will not
operate at the higher rates. These are identified by the absence of the "
9
6
" symbol.
If one (or two) of these large presets is loaded, the
H8000FW will not allow
Int 88.2
or
Int 96kHz
to
be selected and will not lock to any digital source above
50kHz. It may be necessary to unload both A and B
presets before a higher sampling rate can be selected.
Similarly, if one of these higher clock rates is selected, or the system is locked to a digital
source above 50kHz, the H8000FW will not allow these larger programs to be loaded.
