Key Features
oadRunner is a complete package. It is housed in a rugged case
and includes a foldaway handle. The complete RoadRunner
package weighs less than 9.5 pounds (4.3 kg). Inside the
RoadRunner case is a full featured 3-channel monaural audio mixer, an
18-bit A-to-D converter, a multi-algorithm codec, a slot for available
plug-in digital interface device (an ISDN terminal adapter is supplied
as standard), an auto-dialer, international AC and DC power supplies,
and a powerful command processor. If you choose, you can connect
your RoadRunner to any digital transmission system through available
ISDN, X.21, V.35 or RS422 digital interface modules.
RoadRunner uses state-of-the-art compression technologies to provide
bi-directional broadcast quality monaural audio over a single 56 or 64
kb/s line. In addition, the RoadRunner can provide bi-directional 20
kHz monaural audio transparently over a single ISDN line at 112 or 128
kb/s. Ancillary data is supported at all bit rates with any MPEG
algorithm.
RoadRunner is easy to use. The RoadRunner front panel controls have
been kept to a minimum, are simple to use, and are clearly labeled. The
front panel controls include mixing levels for three inputs (two
microphone and one switchable mic/line) and individual local and
return level adjustments for two separate headphone outputs.
All audio connections are made through industry standard connectors,
logically located on the front and rear panels. Two balanced XLR
microphone inputs are located on the front panel, as are two standard
¼” headphone jacks. An additional balanced input, switchable
between microphone and line levels, is located on the rear panel. Also
on the rear panel is an XLR balanced line level output and two ¼”
unbalanced local and return audio outputs, ideal for PA feeds,
recording, etc.
