AudioScience Debuts Sound Cards

PCI Express small footprint cards offer 192 kHz sample rates

Audio card specialist AudioScience has two new cards available, the ASI5810 and ASI5811.

Both are 192 kHz-capable half-height PCI Express cards.

The ASI5810 provides one stereo analog and digital input, one stereo analog and digital output, two record streams and four play streams. Audio formats include 8-, 16- and 32-bit PCM. The GPIO features consist of four opto-isolated inputs and two relay isolated outputs.

The ASI5811 adds a low-noise microphone preamp with a software adjustable gain.

Both analog and AES/EBU interfaces are standard on the ASI581x cards. AudioScience says that the analog interface is balanced and uses 24-bit oversampling converters to deliver more than 100 dB of dynamic range with THD+N better than 0.002% at sample rates from 32 kHz to 192 kHz. In addition, the AES/EBU input features a hardware-based sample rate converter with a range of 32 to 192 kHz.

The ASI5811’s balanced microphone input is designed to work with professional studio microphones requiring 48 V phantom power. Gain is adjustable from 20 dB to 60 dB. Processing effects for the ASI5811’s 32-bit floating point DSP include a compressor/limiter/expander, and a three-band parametric equalizer.

Each has SoundGuard technology to prevent damage from lightning strikes and voltage surges.

The cards are Windows 7-, 10- and Server-compatible, along with Linux-compatible. Both are compatible with AudioScience’s Multi-Rate Mixing technology for playback, recording and mixing. They will ship with XLR breakout cables.

President and co-founder of AudioScience Richard Gross said, “This card is perfect for those broadcasting applications that do not require onboard audio compression, such as production. The microphone preamp allows you to create a complete low-cost recording studio which is ideal for producing spots and promos.”
