Digital Audio

The ASI5111 is a professional PCI audio adapter designed for use in radio broadcast production. The adapter offers two stereo record stream from either a balanced analog input or AES/EBU digital input and four stereo play streams mixed to both a balanced analog output and an AES/EBU digital output. Also included is a microphone input, with low noise pre-amp and a 48V phantom supply.

Key Benefits

	Four stereo streams of PCM playback
	Balanced stereo analog input and output
	AES/EBU or S/PDIF digital input and output (software switchable). Two stereo streams of PCM record.
	SoundGuard™ transient voltage suppression protects against lightning and other high voltage surges on all I/O
	Windows 98/NT/2000/XP and Linux software drivers available.
	24bit analog-to-digital and digital-to-analog converters - 100dB SNR and 0.0025% THD+N.
	Up to 8 cards in one system.
	11 to 96kHz sample rates.
	Low noise microphone input with 48V phantom supply and DSP based compressor/limiter and 3 band equalizer.
	MRX™ multi rate mixing technology supports digital mixing of multiple sample rates.


The AudioScience ASI4300 family of digital audio adapters enable cost-effective multi-stream, single sample rate recording and reproduction of MPEG Layer 2 and MP3 digital audio on the PC platform. Utilizing the 32bit PCI bus and the latest generation of 24bit DSPs from Motorola, these cards were designed to deliver the highest performance available to the broadcast industry.
