ASI6714 and ASI6718 - LOW PROFILE PCI Express Sound Cards


The ASI6714 and ASI6718 are low profile professional PCI-Express sound cards designed for use in radio broadcast automation.

Providing up to 16 play streams that are mixed to 4 (ASI6714) or 8 (ASI6718) stereo outputs and up to 2 record streams fed from one stereo input, the ASI6714 and ASI6718 feature AudioScience’s unique “anything to anywhere” mixing and routing.

The ASI6714 and ASI6718 provide both balanced analog and AES/EBU inputs and outputs. The maximum analog input and output level is +24dBu.

A choice of uncompressed PCM, MPEG layer 2 and MP3 is available for both recording and playback. All compression is handled by an on-board floating point DSP, allowing the host computer to focus on other tasks.

ASI6714 and ASI6718 functionality includes MRX™ multi-rate mixing technology that allows streams of different sample-rates and formats to be mixed digitally. TSX™ time scaling allows compression/expansion of any or all playback streams in real time with no change in pitch.

For emerging surround sound applications, SSX2™ mode allows multichannel streams of up to 8 channels to be played and mixed.
