bit/96 kHz.
Featuring an asynchronous transfer system,
is not impacted by computer jitter, and reproduces audio with
complete accuracy.
can be used with computers running Windows and Mac OS X, as well as with an iPad.
High-Performance Mic Preamps
is equipped with high-performance mic preamps that are based on the same design as our H-Series Handy
Recorders.
+48V phantom power can be supplied to each input. INPUT 1 also supports Hi-Z input.
Additionally, H-Series mic capsules can be connected to the
.
Designed with the DJ in Mind
The
features 2 RCA outputs that make it easy to connect DJ mixers or other devices. The balance between
computer playback signals 1-2 and 3-4 can be adjusted for the LINE OUT 2 and PHONES outputs.
For example, you can balance the PHONES output between click and MAIN OUT signals during a live performance. Or
you can balance between the cue and MAIN OUT signals during a DJ performance.
Plus, the PHONES jack delivers enough volume output for use in clubs and other small venues.
Standalone AD/DA Mode
In standalone mode, the
can be used as a high-quality mic preamp and AD/DA converter.
can convert digital output from a DVD or Blu-ray player to analog output, and also convert analog input to
digital output.

Usage Precautions
Interference with other electrical equipment
is designed to minimize the emission
For safety considerations,
of electromagnetic waves and suppress interference from external
is
electromagnetic waves. However, interference could still occur if
placed next to equipment that is very susceptible to interference or that
and
emits powerful electromagnetic waves. If this occurs, place the
the other device farther apart.
—
With any type of digital control device—including the
electromagnetic interference can cause malfunction, corrupt or destroy
data, or cause other unexpected issues. Always exercise caution.
Cleaning
Use a soft cloth to clean the exterior of the unit if it becomes dirty. If
necessary, use a damp cloth that has been wrung out well to wipe it.
Never use abrasive cleansers, wax or solvents such as alcohol, benzene
