CONNECT THE ULTRALITE-MK3 INTERFACE

1 Make sure your computer and the
UltraLite-mk3 are switched off.
2 Plug one end of the UltraLite-mk3 FireWire
cable (included) into the FireWire socket on the
computer as shown below in Figure 3-1.
☛
You can connect the UltraLite-mk3 to an
800Mbit "FireWire B" port using a 9-pin to 6-pin
FireWire B cable (not shown). However, the
UltraLite-mk3 will still operate at its specified
400Mbit (FireWire A) data rate.
3 Plug the other end of the FireWire cable into the
UltraLite-mk3 I/O as shown below in Figure 3-1.

☛
Make absolute sure to align the flat side of the
FireWire plug properly with the flat side of the
FireWire socket on the UltraLite-mk3. If you
attempt to force the plug into the socket the wrong
way, you can damage the UltraLite-mk3.

CONNECT AUDIO INPUTS AND OUTPUTS

The UltraLite-mk3 audio interface has the
following audio input and output connectors:
10 balanced quarter-inch analog outputs
■
6 balanced quarter-inch analog inputs
■
2 XLR/quarter-inch "combo" analog inputs with
■
preamps
1 pair of RCA S/PDIF in and out
■
Here are a few things you should keep in mind as
you are making these connections to other devices.
Mic/instrument inputs
Connect a microphone, guitar, instrument or other
analog input to the XLR/TRS combo jack with
either a standard mic cable or a balanced cable with
a quarter-inch plug.
☛
Do not connect a +4 (line level) XLR cable to
the front-panel inputs (because of the preamps).
Use a rear-panel quarter-inch input instead.
Phantom power
If you are connecting a condenser microphone or
other device that requires phantom power, move
the 48V phantom power switch on the front panel
to the up position (enabled).
Trim
Both the low-impedance XLR jack and the high-
impedance TRS jack are equipped with 24dB of
trim control. Use the digital trim knobs on the
front panel to adjust the input level as needed for
each input. The LCD provides visual feedback as
you turn the trim knob. The UltraLite-mk3's input
trims are digital controlled, so they allow you to
make fine-tuned adjustments in precise 1dB
increments. You can also adjust trim in the MOTU
CueMix FX software. See "Input trim" on page 69.
