combo jack analog inputs. By connecting the 8pre
optical output to another device, such as another
ADAT-optical equipped interface or a digital
mixer, you add an additional eight mic inputs to
your system, as demonstrated in Figure 4-5 on
page 21. This can be done at any sample rate up to
96 kHz.
To set the sample rate (or clock mode) when
operating as an 8-channel optical expander, see
“Setting the clock source in converter mode” on
page 27.
CONNECT MIDI GEAR
Connect your MIDI device’s MIDI IN jack to the
8pre’s MIDI OUT jack (Connection A below).
Conversely, connect the MIDI device’s MIDI OUT
jack to the 8pre’s MIDI IN jack (Connection B).
Figure 4-2: Connecting a MIDI device to the 8pre.
One-way MIDI connections
MIDI devices that do not receive MIDI data, such
as a dedicated keyboard controller, guitar
controller, or drum pad, only need Connection B
shown in Figure 4-2. Similarly, devices that never
send data, such as a sound module, only need
Connection A. Make both connections for any
device that needs to both send and receive MIDI
data.
Connecting additional gear with MIDI THRUs
If you need to connect several pieces of MIDI gear,
run a MIDI cable from the MIDI THRU of a device
already connected to the 8pre to the MIDI IN on
the additional device as shown below in Figure 4-3.
The two devices then share the 8pre’s MIDI OUT
port. This means that they share the same set of 16
MIDI channels, too, so try to do this with devices
that receive on only one MIDI channel (such as
effects modules) so their receive channels don’t
conflict with one another.
