d) S/PDIF Destinations. The z-8.8a can accommodate up to four S/PDIF digital destination,
for a total of eight channels of S/PDIF output from the z-8.8a. S/PDIF sources include the
S/PDIF input to a digital-to-analog (D/A) converter, the S/PDIF input to a DAT machine, or
the S/PDIF input of a computer soundcard.
Operating the z-8.8a
How to set up a routing pattern.
Setting up a routing pattern is very simple. You need only use the source and destination knobs
and keep an eye on the routing pattern display and the destination legend. The desired
destination is indicated on the destination legend. To control a given destination, simply turn
the destination knob until the digit above the desired destination on the destination legend
blinks. Then turn the source knob until the desired source number is showing; turn the
destination knob
to the next desired destination and repeat. Continue until all the destinations
are set up as desired. Notice that nothing has happened to the audio yet. Also, notice that any
time you rotate a knob, the display blinks. This is to notify you that the routing pattern may have
been changed and needs to be sent to the crosspoint matrix, which is what physically changes the
audio routing inside the z-8.8a. To send the routing pattern to the crosspoint matrix, simply press
the route button.
It is very important to note that the routing changes shown on the routing pattern display do
not take effect until the route button is pressed. This allows you to edit the routing pattern
without having to invoke any intermediate changes on the way to your final routing pattern. You
are also further assured that your routing changes won't affect the audio path until you are ready
for them to do so.
You will notice that destination number 8 is special. It is the number we have assigned to the
S/PDIF sources and destinations. On the destination legend, we have painted the number 8 in
red and labeled it S/PDIF so that you will always remember that this is where the S/PDIF sources
and destinations get connected.
How to save a preset.
Once you have defined a routing pattern, it is a simple matter to save it to the z-8.8a's permanent
internal memory so that you can later recall it. Press the save button once and you will see that
the routing pattern display has changed to a patch number display. Rotate the source knob to
choose a preset number. Once you have the number you wish, press the save button again. This
will write the routing pattern to the z-8.8a's nonvolatile memory. If you wish to cancel the save
operation when you're in save mode, simply press the route button to exit from save mode and
return to normal routing mode.
How to load a preset
Recalling a pre-defined routing pattern is also very easy. Press the load button once and you will
see the routing pattern display has changed again to a patch number display. Rotate the source
knob
to choose which preset you wish to load. Press the load button again to accept this preset.
You will be returned to normal routing mode and you will see your preset in the routing pattern
display
. Don't forget to hit the route button to send the routing pattern to the crosspoint matrix.
If you wish to cancel the load operation when you're in load mode, simply press the route button
to exit from load mode and return to normal routing mode.
