Description
The DiGiCo MOD-SDR-AESO is a four-stereo AES/EBU output card designed to provide high-quality digital audio distribution from compatible DiGiCo systems. It delivers eight digital audio output channels across four stereo AES connections. The card is designed for professional applications where reliable digital transmission and flexible system integration are essential. Its high-quality AES interface supports accurate audio delivery to external digital processors, amplifiers, recording systems, and other compatible equipment. The compact modular design allows it to be integrated directly into supported DiGiCo racks. This makes it a practical solution for expanding digital output capability in professional audio systems.
Sample Rate Conversion
The MOD-SDR-AESO features sample rate conversion to provide additional flexibility when connecting digital equipment operating at different clock rates. SRC can be switched per AES output on appropriately specified output modules. This helps simplify integration within systems containing multiple digital devices and varying sample-rate requirements. Supported operating rates include 44.1 kHz, 48 kHz, and 96 kHz. The conversion functionality helps maintain compatibility while preserving the integrity of the digital audio signal. It is particularly useful in complex broadcast, live sound, and installation environments.
High-Quality Digital Transmission
The card complies with or exceeds AES3 / IEC-60958 Type I 2003 requirements for professional digital audio transmission. It provides a 20 Hz to 20 kHz frequency response at 0 dBFS and supports 24-bit resolution when sample rate conversion is disabled. The output stage is designed for reliable digital signal transmission with controlled impedance. Low-jitter performance helps maintain accurate timing throughout the digital signal path. These characteristics make the card suitable for demanding professional audio applications. It provides dependable AES/EBU connectivity without unnecessary external conversion equipment.
Flexible Output Connectivity
Four stereo AES outputs provide a total of eight digital audio channels from a single card. The outputs can be used to feed external digital equipment such as amplifiers, processors, consoles, recording systems, and broadcast infrastructure. The card supports transformer-balanced 110 Ω AES connections, with optional 75 Ω unbalanced operation where specified. This provides flexibility when integrating the card into different digital audio infrastructures. Its high channel density makes it especially useful where rack space and system efficiency are important. The result is a compact and versatile digital output solution.
Broad DiGiCo Compatibility
The MOD-SDR-AESO is designed for integration with the DiGiCo SD-Rack, SD-MiNi Rack, SD-Nano Rack, SD-Range, and 4REA4 platforms. Its modular format allows it to become part of a larger DiGiCo I/O configuration. The card can expand the digital output capacity of a system without requiring a separate external interface. This makes it suitable for live production, touring, theatre, broadcast, corporate AV, and fixed installation applications. Its compatibility with multiple DiGiCo platforms provides flexibility when designing or upgrading professional systems. The card is engineered to work as part of DiGiCo's modular I/O ecosystem.
Hot-Plug Design
The card is designed to support hot-plug operation, helping simplify installation and maintenance in professional environments. Engineers can configure or replace compatible modules with reduced system downtime. This is particularly useful for touring systems, rental inventories, and installations where rapid servicing is important. The modular architecture also makes it easier to customize DiGiCo racks according to specific I/O requirements. Combined with its compact form factor, the hot-plug capability contributes to efficient system management. It provides a practical solution for professionals who require reliable and serviceable digital infrastructure.
