15. Power Input ((9V DC 3.5A - 4A) – Connect the included power supply to this jack.
NOTE: Fast Track Ultra 8R is designed to work with 9V DC power supplies with
a 3.5 - 4A rating. If you need to purchase an additional power supply for your
Fast Track Ultra 8R, be sure to buy one with the correct rating and polarity. Replacement
power supplies are available at the M-Audio webstore.
16. USB Connector ( USB 2.0) – Connect a standard USB cable to this port, connecting the other end to
your host computer.
NOTE: Fast Track Ultra 8R is a USB 2.0 device and must be connected to a USB 2.0
port on your computer. USB 1.0/1.1 operation is not supported.
17. Kensington ® Lock Port ( ) – This connector is compatible with Kensington ® security cables to protect your
device from theft.
18. MIDI and S/PDIF Connector (MIDI S/PDIF) – The accompanying breakout cable connecting to this
multi-pin jack provides MIDI input and output on 5-pin DIN connectors, and S/PDIF input and output on coaxial
RCA connectors.
• When the Sync Source drop-down menu is set to “External” in the Control Panel, input channels 7 and 8
will receive their signal from the S/PDIF input instead of analog inputs 7/8.
• The S/PDIF output signal is identical to the output of Line Outputs 7/8.
• The S/PDIF output will also support pass-through of AC-3 or DTS encoded surround formats.
19. Line Outputs – These eight balanced/unbalanced 1/4” (TRS) jacks provide eight analog outputs. The level
of output pair 1/2 is controlled by the front-panel master volume knob
10 . Signal present at outputs 7 and 8 is
duplicated at the S/PDIF outputs.
20. Mic/Line Inputs – These eight combo jacks provide eight
analog inputs, and can accommodate microphone or
line-level sources via XLR or 1/4” TRS or TS connectors.
The microphone (XLR) inputs route signals to the interface’s
preamplifiers while the line-level (1/4”) jacks bypass the
preamplifiers.
The input source for channels 1 and 2 can be selected via
the front-panel Mic/Line – Instrument switches
2 between
Mic/Line inputs 20 or the front-panel Instrument inputs 1 .
Selecting “External” from the Sync Source drop-down menu
in the control panel will activate the S/PDIF input as the
signal source for input channels 7 and 8. Mic/Line inputs
7 and 8 will be disabled in this configuration.
21. Inserts – Insert jacks allow you to add analog outboard
effects (compressors, limiters, etc.) into the signal path of
the first two channels of your Fast Track Ultra 8R. Outboard
effects are “inserted” between the preamp and the A/D converter.
These 1/4” TRS jacks are only active when a a special “insert” cable is connected to these jacks (see the box
entitled “About Insert Cables” to learn more about these cables). If no insert cable is connected, these jacks do
not affect the signal path.
About Insert Cables:
An insert cable is wired in a way that lets you send
and receive signals over a single cable. This cable
features a “TRS” (tip-ring-sleeve) connector on one
side and two “TS” (tip-sleeve) connectors on the
other. The TRS side connects to one of the insert
jacks of Fast Track Ultra 8R. The TS connectors are
usually labeled “tip” (send) and “sleeve” (return).
Attach the “tip” connector to your external device’s
input and the “sleeve” connector to the device’s
output. This allows signals to be sent to the external
device and returned to the A/D converter on
Fast Track Ultra 8R.
