ABOUT THE ULTRALITE-MK3 HYBRID
11
control software for Mac and Windows. This allows
you to fine-tune trim settings for synths, effects
modules and a wide variety of analog inputs for
optimum levels. Different trim configurations can
then be saved as files on disk for instant recall.
S/PDIF
The UltraLite-mk3 rear panel provides RCA “coax”
S/PDIF input and output.
MIDI I/O
The UltraLite-mk3’s standard MIDI IN and MIDI
OUT jacks supply 16 channels of MIDI I/O to and
from the computer via the UltraLite-mk3’s
FireWire connection.
On-board SMPTE synchronization
The UltraLite-mk3 can resolve directly to SMPTE
time code via any analog input, without a separate
synchronizer. It can also generate time code via any
analog output. The UltraLite-mk3 provides a
DSP-driven phase-lock engine with sophisticated
filtering that provides fast lockup times and sub-
frame accuracy.
The included MOTU SMPTE Console™ software
provides a complete set of tools for generating and
regenerating SMPTE time code, which allows you
to slave other devices to the computer. Like
CueMix FX, the synchronization features are
cross-platform and compatible with any audio
sequencer software that supports the ASIO2
sample-accurate sync protocol.
Hybrid FireWire/USB2 connectivity
FireWire has long been recognized as a reliable,
high-performance connectivity standard for
professional MOTU audio interfaces. Meanwhile,
hi-speed USB2 has also developed into a widely
adopted standard for connecting peripheral
devices to personal computers.
To fully support both formats, your UltraLite-mk3
Hybrid audio interface is equipped with both a
FireWire A (400 Mbit/sec) connector and a hi-
speed USB2 (480 Mbit/sec) connector, and you can
use either port to connect the UltraLite-mk3 to
your computer. This gives you maximum flexibility
and compatibility with today’s ever-expanding
universe of Mac and Windows computers.
The UltraLite-mk3 has the ability to power itself
from its FireWire connection to the computer, for
convenient, mobile bus-powered operation.
Power supply
If you do not want the UltraLite-mk3 to draw
power from the computer, and AC power is
available, you can power the UltraLite-mk3 from
any standard 10-18V, 12 watt DC power supply
with any polarity (tip positive or negative).

Headphone output and main volume control
The UltraLite-mk3 front panel provides a quarter-
inch stereo headphone output jack and volume
knob. The LCD display provides feedback as you
turn the knob. The VOL knob can be used to
control the volume of the main out jacks on the rear
panel. It can alternately be configured to control
any combination of outputs.
Programmable backlit LCD display
Any UltraLite-mk3 setting, including the powerful
CueMix FX on-board 16-bus mixer with effects,
can be accessed directly from the front panel using
the four rotary encoders and the 2x16 backlit LCD
display.
