ABOUT THE AUDIO EXPRESS
11
Digital Performer. Therefore, pressing the foot
switch is the same as pressing the 3 key. The Audio
Express Control Panel software lets you program
any keystroke you wish.
On-board SMPTE synchronization
The Audio Express 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 Audio Express 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
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,
high-speed USB2 has also developed into a widely
adopted standard for connecting peripheral
devices to personal computers.
To fully support both formats, your Audio Express
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 Audio Express to
your computer. This gives you maximum flexibility
and compatibility with today’s ever-expanding
universe of Mac and Windows computers.
The Audio Express 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 Audio Express to draw
power from the computer, and AC power is
available, you can power the Audio Express from
any standard 9-18V, 5 watt DC power supply with
any polarity (tip positive or negative).
THE AUDIO EXPRESS FRONT PANEL
Front-panel mixing
The six digital rotary encoders on the Audio
Express front panel provide hands-on mixing of all
live inputs. In fact, these controls provide control of
up to four separate mixes. Use the MIC, LINE and
S/PDIF knobs to control input volume for each
mix; push the MIX knob to cycle among the four
different mixes, plus trim mode, which lets you
adjust input trim for each across all mixes.
48V phantom power and pad
The two MIC knobs let you toggle independent
48V phantom power and -20 dB pad settings for
the two mic inputs. See “Mic/guitar inputs with
preamps” on page 10.
Headphone output and main volume control
The Audio Express front panel provides a quarter-
inch stereo headphone output jack and volume
knob, which can be configured to control phones
volume, phones and main outs together, or the
main outs by themselves.
Status and metering LEDs
The LED section provides visual indication of
audio levels, audio activity status, and the current
settings for all front-panel controls.
16-BIT AND 24-BIT RECORDING
The Audio Express system handles all data with a
24-bit signal path, regardless of the I/O format. You
can record and play back 16-bit or 24-bit audio files
at any supported sample rate via any of the Audio
Express’s analog or digital inputs and outputs. 24-
bit audio files can be recorded with any compatible
host application that supports 24-bit recording.
