Available in both ISA and PCI versions, the PCX11+ was one of our most popular models for broadcast automation and audio production. It features balanced analog inputs and outputs and an LTC (SMPTE) input. An optional board provides digital input/output in AES/EBU or SPDIF formats. (The digital option requires an additional slot in the ISA version, but is integrated in the PCI version.)
Replaced by the PCX924.
The PCI version also has a dedicated CD-ROM input.
The PCX11+ is full duplex, offering simultaneous and independent record and playback.
Sampling frequencies supported are 8, 11.025, 16, 22.05, 24, 32, 44.1, and 48 kHz.
The PCX11+ performs real-time, simultaneous MPEG Layer I and Layer II compression and decompression during record and playback. Support provided for Layers I and II of the MPEG Audio standard (ISO 11172-3) and the low sampling frequencies of the MPEG-2 Audio standard (ISO 13818-3).
When using applications based on the Digigram np SDK:
Real-time mixing of multiple sound files, level adjustment, panning, cross fade, punch-in/punch-out, scrubbing, time-stretching, pitch-shifting, and format and frequency conversions are performed on the DSP.
Multiple applications may share the resources of a single card.
Analog inputs and outputs may be configured as one stereo or two mono channels.
Interboard synchronization is possible for operation of multiple. Up to 16 stereo hardware inputs and 16 stereo hardware outputs can be managed simultaneously across multiple cards in the same PC.作者: yuechu 时间: 2005-6-30 07:40:52
