e) Route button. Press the route button to send the state displayed by the routing pattern
display to the z-8.8a's internal routing matrix. Pressing the route button also makes the
routing pattern display stop blinking.
f) Load button. Press this button to invoke the preset load mode and to execute the load
command. Use the source knob to select the preset number to be loaded. Press the route
button
to send the loaded preset to the routing matrix.
g) Save button. Press this button to invoke the preset save mode and to execute the save
command. Use the source knob to select the preset number to which you wish to save the
routing configuration.
h) Synchronize button. Press this button to engage sample rate conversion on all four S/PDIF
source inputs (collectively known as "source 8"). This is necessary if the S/PDIF sources are
not at exactly the same sample rate and locked to the ADAT destination to which they are
being connected.
i) Synchronize LED. This LED gives a visual indication of whether or not sample rate
conversion is engaged on the S/PDIF source inputs to the z-8.8a.
Rear Panel Connections
On the rear panel of the unit you will see four groups of connectors. These are for the following:
a) Lightpipe Sources. The Lightpipe sources are outputs from source machines. For example,
the eight-channel digital audio output from an ADAT could be hooked up to one of the
Lightpipe source inputs. The Lightpipe sources also support standard two-channel S/PDIF
optical format signals (although they cannot be converted to ADAT format signals)
b) Lightpipe Destinations. The Lightpipe destinations are inputs to destination machines. For
example, the output from one of the Lightpipe destinations could be hooked up to the eight-
channel digital input of an ADAT. The Lightpipe destinations also support standard two-
channel S/PDIF optical format signals (although they cannot be converted to ADAT format
signals)
c) S/PDIF Sources. The z-8.8a can accommodate up to four S/PDIF digital sources, for a total
of eight channels of S/PDIF input to the z-8.8a (recall that each S/PDIF line carries a stereo
pair). S/PDIF sources include the S/PDIF output from a CD transport or the S/PDIF output
from a sampler or DAT machine, and the S/PDIF output from an analog-to-digital (A/D)
converter.
