chain multiple interfaces — up to four MOTU
FireWire interfaces — on a single FireWire bus. It
can also be used to connect other FireWire devices
without the need for a FireWire hub.
On-board SMPTE synchronization
The 8pre can resolve directly to SMPTE time code
via any analog input, without a separate
synchronizer. The 8pre provides a DSP-driven
phase-lock engine with sophisticated filtering that
provides fast lockup times and sub-frame
accuracy.
The included MOTU SMPTE Setup™ software
provides a complete set of tools to generate SMPTE
for striping, regenerating or slaving other devices
to the computer. Like CueMix DSP, the synchroni-
zation features are cross-platform and compatible
with all audio sequencer software that supports the
ASIO2 sample-accurate sync protocol.
THE 8PRE FRONT PANEL
Preamp trims, 48V phantom power and pad
The 8pre front panel provides convenient,
individual trim control, 48-volt phantom power
switch and 20 dB pad switch for each analog input.
Headphone output and main volume control
The 8pre front panel includes a quarter-inch stereo
headphone output jack and volume knob. The
volume knob also controls the rear-panel main
outs. Push the knob to toggle between them.
Metering section
The front panel of the 8pre displays input metering.
The five-segment input meters provide dedicated
multi-segment metering for their respective analog
inputs.
The
Mode
lights indicate whether the interface is
currently operating as a FireWire audio interface or
an analog-to-optical converter.
The
Clock
lights indicate the global sample rate and
clock source.
16-BIT AND 24-BIT RECORDING
The 8pre 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 8pre’s
analog or digital inputs and outputs. 24-bit audio
files can be recorded with any compatible host
application that supports 24-bit recording.
HOST AUDIO SOFTWARE
The 8pre system ships with a standard WDM
Windows driver that allows you to record, edit,
play back and mix your 8pre projects using your
favorite Windows audio software. In addition, this
driver provides legacy Wave/MME compatibility
for older applications that do not yet support
WDM.
The 8pre also includes a ASIO and GSIF drivers for
multi-channel compatibility with any audio
applications that support these drivers.
A COMPUTER-BASED SYSTEM
Regardless of what software you use with the 8pre,
the host computer determines the number of
tracks the software can record and play simulta-
neously, as well as the amount of real-time effects
processing you can apply to your mix. A faster
computer with more RAM and faster hard drives
will allow more simultaneous tracks and real-time
effects than a slower computer with less RAM and
slower hard drives. Today’s fastest computers can
typically play as many as 72 tracks or more.
Standard third-party high-performance hard drive
solutions can also help you achieve higher track
counts.
