Connecting A Digital Mixer - Fostex D-160 Owner's Manual

4-3. Connecting a digital mixer

As shown in the figure, connecting the input and output connectors of the D-160 to
the output and input of a digital mixer respectively may cause digital looping.
When you select a digital input track, the D-160 will automatically enter "sync to the
external word clock in digital input signal" mode. If you set the connected digital
mixer to the same condition (that is, "sync to the external word clock in digital input
signal" mode), both devices will try to lock to the external word clock, resulting in a
digital loop that prevents synchronization from being established.
To avoid this situation, follow one of the suggestions below, depending on the type
of the connected mixer.
A. Using a digital mixer that accepts a digital signal if you select its internal clock as sync source:
The mixer is always able to input and output a digital signal to and from the D-160.
Select an appropriate digital signal to input in the "digital input track" parameter on
the D-160. The D-160 will lock to the external word clock.
B. Using a digital mixer that locks to the external clock when you select digital input on the D-160:
You need to change the settings on both devices. If you wish to input a digital signal
to the D-160, select an appropriate digital signal to input in the "digital input track"
parameter. You cannot select "digital in" on the digital mixer. On the other hand, if
you wish to input a digital signal to the digital mixer, select "digital in" on the digital
mixer, and set the "digital input track" parameter of the D-160 to "L-- R--" (no
assignment).
This section uses a digital mixer as an example, but the same problem applies to any
other digital device. Any digital device (DAT, adat, etc.) can replace the digital
mixer in this explanation.
The precaution described above applies to a system in which both the input and
output of the D-160 are connected to the output and input of the external device
respectively. If you connect either one of them (output or input), the device that
accepts the input signal will lock and sync to the output device.
The example here uses a digital mixer that can accept a digital input signal when
its internal clock (INTERNAL) is selected.
Connecting a digital mixer
Connect the DATA INPUT of the D-160 to the digital output jack of the digital mixer, and
the DATA OUTPUT of the D-160 to the digital input jack of the mixer.
