Setting the System Clock & Digital Out Sync
The system clock and DIGITAL OUT sync source can be set as follows.
1
Press the UTILITIES button, then select the DIGI page shown below.
2
Select the parameters, and use the JOG dial to set them as required.
System clock
This parameter determines the sampling rate and source of the Z8’s system clock.
44.1 kHz:
Sets the system clock to 44.1 kHz.
48 kHz:
Sets the system clock to 48 kHz.
96 kHz:
Sets the system clock to 96 kHz. The polyphony is reduced by half.
When the JOG dial is rotated, a window appears for you to select the system clock. Select
the system clock, and then press “DO IT.”
DIGITAL OUT sync
This parameter allows you to set the sync source for the DIGITAL OUT independently
of the Z8’s system clock. This is convenient when the Z8’s system clock is running at,
for example, 96 kHz, and you need to integrate the Z8 into a system that is running at
44.1 kHz. By connecting an external 44.1 kHz clock to the WORDCLOCK IN, and set-
ting the DIGITAL OUT sync source to the WORDCLOCK IN, you can output digital
audio at 44.1 kHz via the DIGITAL OUT regardless of the fact that the Z8’s internal
clock is running at 96 kHz.
INTERNAL:
Synchronizes the DIGITAL OUT signal to the Z8’s system clock.
DIGITAL IN:
Synchronizes the DIGITAL OUT signal to the digital audio signal being
received by the DIGITAL IN.
ADAT IN:
Synchronizes the DIGITAL OUT signal to the digital audio signal being
received by the ADAT IN.
WORDCLOCK:
Synchronizes the DIGITAL OUT signal to the clock signal being
received by the WORDCLOCK IN.
Type
This parameter enables you to select the data format of the digital output.
CONSUMER:
This format is commonly used for CD players, DAT players, and other
consumer products.
PROFESSIONAL:
This format is primarily used on the industry’s professional equipment.
ADAT out 1/2
This parameter appears only when an optional ADAT board is installed. Select the signals
output from ADAT out 1/2. When you select “1/2,” the signals output from Individual out
1/2 are also output from ADAT out 1/2. When you select “L-R,” the signals output from
MAIN OUT (L/R) are also output from ADAT out 1/2.
Warning: When the system clock is changed, the Z8 is reset and the memory contents
cleared. Be sure to save any important data before changing the system clock.
