. Power Input (5V DC) – Connect the included 5VDC 2000mA power supply to this jack.
• NOTE: Due to the limitations of the USB bus, powering Fast Track Ultra via the USB bus will limit its
functionality to 4 input/4 output operation using analog inputs and outputs 1/2 and the S/PDIF I/O.
16
. Line Outputs (Outputs) – These six balanced 1/4-inch (TRS) jacks provide six analog outputs. The level of
outputs 1/2 is controlled by the front-panel main output knob

17
. USB Connector (USB 2.0) – Connect a standard USB cable to this port, connecting the other end to your host
computer.

. S/PDIF Input (S/PDIF In) – Digital input on a coaxial (RCA-type) connector. This input will accept a digital input
signal at any of the supported sample rates.
21
. S/PDIF Output (S/PDIF Out) – Digital output on a coaxial (RCA-type) connector. This output will also support
pass-through of AC-3 or DTS encoded surround formats.
• NOTE: When AC-3 or DTS encoded signals are passed through this output, all analog inputs and outputs will
be muted.
22
. Line Inputs (Inputs) – These six balanced/unbalanced 1/4-inch (TRS) jacks provide six analog inputs for channels
1 through 6. Inputs for channels 1 through 4 are selectable between these inputs and the front-panel combo/XLR
inputs

. Inserts (Inserts) – These 1⁄4” TRS jacks are configured to connect to an analog outboard compressor/limiter or
other effect inserting the effect between the preamp and the A/D converter. These inserts are only active when a
connector is inserted, and are otherwise bypassed. The TRS jack is configured as follows: Tip=Send; Ring=Return;
Sleeve=Ground.
➤ IMPORTANT NOTE: Fast Track Ultra can be powered via the included AC power
supply or via bus power from the host computer. However, when running on bus power,
Fast Track Ultra will be limited to four inputs and four outputs. These are mapped to
inputs 1/2, outputs 1/2, and the S/PDIF I/O.
