FEATURES
- Ultra High-speed PCI bus six stereo devices
on 5 physical outputs available simultaneosly
on one soundcard.
- Separate record and playback subsystems,
each with ndependent sample clack.
- Flexible digital mixing and volume control
between all channels within each subsystem.
- Supports the most popular compression formats
including MPEG Layer I and II, ADPCM and more.
- Recording and production of spots and phone
calls simultaneously with on-air playback on a
single PC — eliminating the need far separate
workstations or additional soundcards, and
making digital broadcast systems far more
affordable to develop and use.
- 6 stereo devices available between two
subsystems.
- Three 32-bit floating point DSPs.
- 20-bit converters with an SRAM buffer depth of
384k bytes prevents dropouts in high latency
networked environments.
- Optional LTC (Longitudinal Time Code) input.
- On-board header to accept an Antex daughter
card that will breakout the outputs into
- AES/EBU digital for simultaneous, parallel
access to all analog and digital outputs. This is
a field upgrade and will not require returning
the card to Antex.
- Optional General Purpose opto-isolated 16-bit
digital I/Os, with a serial data stream to allow
system integrators future expansion for control-
ling keypad switches, user interface functions,
timers and other broadcast installation functions.
- Drivers are available for Windows 95/98,
Windows NT.
- Strict adherence to Microsoft WAV standards
allows compatibility with a broad range of appli-
cations. A high level Software Developers Kit
(SDK) simplifies utilization of advanced features.
APPLICATIONS:
- Broadcast automation
- Digital audio mastering and recording
- Kiosks and other integrated computer audio systems
SOFTWARE:
Antex Broadcaster driver software allows an
application program to provide direct-to-disk digital
sound sampling and reproduction. When used in
conjunction with the Broadcaster’s Software Developers
Kit (SDK), system integrators can add to their application
programs high performance digital audio record, play
and mixing functions featuring the most advanced
compression algorithms.
