16-Bit And 24-Bit Recording; Cuemix Fx 32-Bit Floating Point Mixing And Effects - MOTU Traveler-mk3 User Manual

Bus power provides convenient portability with
laptop computers. An external battery pack
provides both portability and extended operation,
even in remote locations. The included DC power
supply allows for stand-alone operation as a mixer,
without a computer. (The Traveler-mk3 can also
run stand-alone with a battery pack.)
Battery power
The 4-pin XLR battery power jack allows you to
connect a standard DC battery pack for extended
remote recording. The battery pack must supply a
minimum of 10-18 volts and 12 watts. For further
details, contact your preferred supplier of
professional audio/video equipment.
Power supply
If you do not want the Traveler-mk3 to draw power
from the computer, and AC power is available, you
can power the Traveler-mk3 from any standard
10-18V, 12 watt DC power supply with any polarity
(tip positive or negative).

16-BIT AND 24-BIT RECORDING

The Traveler-mk3 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
Traveler-mk3's analog or digital inputs and
outputs. 24-bit audio files can be recorded with any
compatible host application that supports 24-bit
recording.
CUEMIX FX 32-BIT FLOATING POINT
MIXING AND EFFECTS
All Traveler-mk3 inputs and outputs can be routed
to the on-board CueMix FX 16-bus (8 stereo)
digital mixer driven by hardware-based DSP with
32-bit floating point precision. The mixer allows
you to apply no-latency effects processing to
inputs, outputs or busses directly in the
Traveler-mk3 hardware, independent of the
computer. Effects can even be applied when the
Traveler-mk3 is operating stand-alone (without a
A B O U T T H E T R A V E L E R - M K 3
computer) as a complete rack-mounted mixer.
Input signals to the computer can be recorded wet,
dry, or dry with a wet monitor mix (for musicians
during recording, for example).
Effects include reverb, parametric EQ and
compression/limiting. The Traveler-mk3's Classic
Reverb™ provides five different room types, three
frequency bands with adjustable crossover points,
shelf filtering and reverb lengths up to 60-seconds.
Two forms of compression are supplied: a standard
compressor with conventional threshold/ratio/
attack/release/gain controls and the Leveler™, an
accurate model of the legendary LA-2A optical
compressor, which provides vintage, musical
automatic gain control.
CueMix FX also provides 7-band parametric EQ
modeled after British analog console EQs,
featuring 4 filter styles (gain/Q profiles) to
effectively cover a wide range of audio material.
Low-pass and high-pass filters are also supplied
with slopes that range from 6 to 36 dB. The EQ
employs extremely high precision 64-bit floating
point processing.
The Traveler-mk3's flexible effects architecture
allows you to apply EQ and compression on every
input and output (a total of 58 channels), with
enough DSP resources for at least one band of
parametric EQ and compression on every channel
at 48 kHz. However, DSP resources are allocated
dynamically and a DSP meter in the CueMix FX
software (included) allows you to keep tabs on the
Traveler-mk3's processing resources. Each input,
output and mix bus provides a send to the Classic
Reverb processor, which then feeds reverb returns
to mix busses and outputs, with a selectable split
point between them to prevent send/return
feedback loops.
