DolbyFax ™
DolbyFax™, longtime favorite of the Film and Television community, is increasingly finding a home in Album Recording. While earlier DolbyFax units use only the Dolby AC-2 algorithm, the new DP503/524 codecs feature multiple algorithms AC-2 in stereo and mono, AC-3 two channel, and even MPEG Layer 2, as well as integrated front panel control and an internal speed-dial directory. DolbyFax usually requires only two ISDN BRI lines for standard AC-2 256Kbit operation, delivering two 20kHz discrete audio channels in each direction! The basic DolbyFax setup is a DP503 Encoder, DP524 Decoder, Ascend Terminal Adapter, and Ascend hand-held terminal for diagnostics and maintenance. Typical DolbyFax applications are long distance session supervision, mix approvals, ADR, music overdubs, and sound design collaboration.

Codec of choice for Film, TV, Music Albums, Film/TV and Music Recording!
DolbyFax PLUS
The popular DolbyFax™ becomes even more useful when coupled with the Colin Broad IS-1 ISDN Synchronizer. We call this combo DolbyFax PLUS. The IS-1 is a clever device that adds an independent timecode channel to the DolbyFax’s two bi-directional audio channels. Send 20kHz stereo audio and timecode in the same directions over the same two ISDN lines! DolbyFax PLUS allows remote control of a serially controlled deck at the distant location. You can Stop, Start, Rewind, Fast Forward, even Record on an unattended VCR or DAT machine at the other end of your DolbyFax connection!
The IS-1 is also a complete Timecode Synchronizer. It syncs any RS-422 controlled video or audio device, both as a true timecode synchronizer (replaces two lynxes), or as a code-only master (chase) synchronizer. The unit pictured is packaged in an optional lightweight fiber carrying case. Typical DolbyFax PLUS applications are mix approvals with synced video, ADR, video laybacks, element delivery; your imagination is the only limit to the applications.
