Eleven Rack User Guide72
To connect a digital device to Eleven Rack, do one
of the following:
• Connect the AES/EBU output on the device to
the AES/EBU input on Eleven Rack, and the
device’s AES/EBU input to Eleven Rack’s
AES/EBU output, with two AES/EBU-format
XLR cables.
– or –
• Connect the S/PDIF output on the device to
the S/PDIF input on Eleven Rack, and the de-
vice’s S/PDIF input to Eleven Rack’s S/PDIF
output port, using two 75-ohm coaxial cables
with male RCA connectors on both ends.
Configuring Digital Devices
When connecting to external gear digitally,
Eleven Rack and Pro Tools must be set to the
same sample rate and digital format as your dig-
ital device. Pro Tools must also be set to clock
from the digital device, or no audio can pass be-
tween them.
To configure Pro Tools to interface with a digital
device:
1 Choose Setups > Hardware Setup.
2 Select AES External or S/PDIF External from the
Clock Source pop-up menu, to match with the
device.
3 Change the sample rate of your external de-
vice to match the rate you are using or plan to
use in your Pro Tools session. If your device op-
erates in a limited range of sample rates, you’ll
need to stay within that range when choosing
the sample rate for your Pro Tools session.
4 Click OK.
At this point, you can try to record some signal
from the digital device (if it is a sound source,
like a keyboard or CD player), inserting it onto a
pre-recorded track (if it’s an effects processor),
and so on.
MIDI Connections
The two MIDI ports on Eleven Rack let you take
advantage of all the MIDI features of
Pro Tools LE, including recording and editing
MIDI data for to automate controls on Eleven
Rack, and/or compose using virtual or hardware
MIDI sound sources.
If you need additional MIDI ports you can add a
compatible USB-based MIDI interface to your
system.
To connect a MIDI device to Eleven Rack:
1 Connect a standard 5-pin MIDI cable from the
MIDI Out port of your device to the MIDI In
port on the back of Eleven Rack.
2 If the device has a MIDI input and you plan to
send MIDI signals to it from Pro Tools, connect
another MIDI cable from the MIDI Out port on
the back of Eleven Rack to the MIDI In port of
your device.
If you get no signal or a compromised signal,
double-check that Pro Tools and your exter-
nal device are set to the same sample rate and
digital I/O format, and that Pro Tools is set
to receive sync from the external device.
