Soundcraft A520.003000SP AES/EBU 8-In/8-Out D-Sub Card

$709.00

The Soundcraft AES/EBU 8-In/8-Out D-Sub Card (model A520.003000SP) is a single-slot expansion card that adds 8 input and 8 output channels of AES/EBU digital audio to compatible Soundcraft Si Series consoles, including the Expression, Performer, and Compact models. It provides connectivity via a 25-pin D-Type connector. The card allows for high-quality, 24-bit/96kHz digital audio transmission with minimal latency and no signal degradation. A dedicated BNC connector for word clock output ensures accurate synchronization with other digital equipment. This makes it ideal for interfacing with external effects processors, digital recorders, and broadcast gear in live, studio, or broadcast environments.

About the Soundcraft A520.003000SP AES/EBU 8-In/8-Out D-Sub Card

The Soundcraft A520.003000SP is a digital audio interface card that provides professional AES/EBU input and output connectivity for compatible Soundcraft Si series digital mixing consoles. AES/EBU is a standard professional format for transmitting two channels of uncompressed digital audio over a single balanced XLR cable or, in this case, via a multi-channel D-Sub connector. This card offers eight discrete AES/EBU input pairs and eight output pairs (16 channels in each direction) through a single 25-pin D-Sub connector, enabling high-fidelity digital interconnection with external devices such as digital recorders, broadcast equipment, or other digital mixers without undergoing unnecessary digital-to-analog conversions.

Installing this card into an available expansion slot on the Si console integrates these digital I/O channels directly into the console's routing matrix. Engineers can then assign these digital streams as inputs from external sources or use the outputs to feed digital processors or recording systems, all while maintaining pristine digital audio quality from end to end. The use of the D-Sub connector allows for a clean and organized setup, as a single cable can carry all 16 channels, which is far more efficient than running multiple individual XLR cables. The card supports standard sample rates and syncs to the console's internal clock or an external word clock reference.

Marked as a spare part ("SP"), this module is available for retrofitting consoles or as a replacement for an existing faulty card. It is an essential component for studios or live sound setups that operate within an all-digital or hybrid digital signal chain. By providing direct AES/EBU access, the card enhances the Si console's versatility, allowing it to function seamlessly as the core of a sophisticated digital audio workflow, ensuring signal integrity is maintained throughout the production chain.
