Description
The DiGiCo MOD-SDR-AES-I is an AES/EBU digital input and output card designed for professional DiGiCo systems. It provides four stereo AES input channels and four stereo AES output channels through BNC connections. The card uses the AES3-id format, which employs 75Ω unbalanced connections commonly used in professional broadcast and video environments. This approach allows reliable digital audio transmission while providing a practical alternative to conventional XLR-based AES3 connections. It is suitable for professional live sound, broadcast, installation, and production applications. The card provides a flexible method of integrating AES-compatible equipment into a DiGiCo system.
BNC AES3-id Interface
The card supports AES signals over BNC connectors using the AES3-id standard. The 75Ω connection format is well suited to installations where longer digital cable runs and professional broadcast-style infrastructure are required. BNC connectivity also provides a familiar connection method for systems using existing digital video and broadcast cabling. The interface is designed to maintain reliable digital signal transmission between compatible equipment. Both input and output connections are available on the card. This makes it useful for integrating digital processors, converters, amplifiers, recording systems, and other AES-compatible equipment.
Flexible Sample Rate Conversion
Sample rate conversion is available on both the AES inputs and outputs, providing additional flexibility when connecting equipment operating at different sample rates. Input sample rates can range from 32 kHz to 99 kHz when sample rate conversion is enabled. Sample rate conversion can be switched independently per AES input. Appropriate output configurations can also provide switchable sample rate conversion per AES output. This allows the card to integrate more easily into systems containing equipment with different digital clocking requirements. It provides engineers with greater control over digital signal routing and compatibility.
Multi-Channel Digital I/O
The MOD-SDR-AES-I provides a total of eight stereo AES channels, with four stereo inputs and four stereo outputs. This gives the card substantial digital I/O capacity while occupying a single modular card position. Each stereo AES connection carries two digital audio channels, making the card suitable for high-density digital system configurations. The available I/O can be used for connecting multiple external digital devices simultaneously. This makes it practical for complex live sound and fixed installation systems. Its compact modular format helps expand system connectivity without requiring additional external interfaces.
High-Quality Digital Performance
The card is designed to comply with or exceed AES3 / IEC-60958 Type I 2003 requirements. It supports 24-bit digital audio resolution when sample rate conversion is disabled and provides a frequency response from 20 Hz to 20 kHz at 0 dBFS. The AES output section is engineered for stable digital transmission with controlled output impedance and low jitter performance. Operating sample rates include 44.1, 48, and 96 kHz. These specifications make the card suitable for professional applications where accurate and reliable digital audio transmission is essential. It provides a high-quality digital interface for demanding audio environments.
