Descripción
The DiGiCo D-RACK-AES-I is an AES/EBU input card designed to provide four stereo AES digital input channels for compatible DiGiCo systems. It uses XLR connectivity for professional digital audio signal input and provides a practical way to expand AES/EBU connectivity within supported hardware. The card is designed for use with the DiGiCo SD-Rack, SD-MiNi Rack, SD-Nano Rack, and 4REA4 platforms. Its four stereo inputs provide connectivity for multiple digital audio sources. The card is suitable for professional live sound, installation, and production environments.
Flexible Digital Input Configuration
The D-RACK-AES-I provides four stereo AES input channels, allowing up to eight digital audio channels to be received. Its input architecture is designed to provide reliable digital signal connectivity for compatible DiGiCo systems. The card uses a 110-ohm transformer-balanced input configuration with a tolerance of plus or minus 5 percent. An optional 75-ohm unbalanced configuration with a plus or minus 5 percent tolerance is also supported. This flexible input configuration allows the card to accommodate different professional digital audio requirements.
Wide-Range Sample Rate Conversion
The card provides wide-range sample rate conversion for flexible integration with different digital audio sources. With sample rate conversion enabled, the supported input sample rate range extends from 32 kHz to 99 kHz. Sample rate conversion can be switched independently for each AES input, allowing different inputs to be configured according to their connected sources. This provides greater flexibility when integrating equipment operating at different sample rates. The feature is particularly useful in complex professional audio systems requiring reliable digital signal integration.
Supported Operating Sample Rates
The D-RACK-AES-I supports operating sample rates of 44.1 kHz, 48 kHz, and 96 kHz. At 48 kHz, the specified operating tolerance is plus or minus 2 Hz. This range provides compatibility with common professional digital audio sample rates used in live sound and production systems. The card also provides a frequency response from 20 Hz to 20 kHz at 0 dBFS. Its digital architecture is designed to provide full-range audio performance within supported system configurations. These capabilities make the card suitable for a variety of professional digital audio applications.
AES3 Standard Compliance
The D-RACK-AES-I complies with or exceeds the requirements of AES3, also identified as IEC-60958 Type I, 2003. This provides a standardized digital audio interface for professional AES/EBU signal transmission. The card's transformer-balanced input design supports dependable signal connectivity within compatible DiGiCo systems. Its 24-bit resolution specification applies when sample rate conversion is switched off. The combination of standard compliance, flexible connectivity, and sample rate conversion makes it a versatile AES/EBU input solution. It is designed for reliable operation in demanding professional audio environments.
DiGiCo System Integration
Designed for the DiGiCo SD-Rack, SD-MiNi Rack, SD-Nano Rack, and 4REA4, the D-RACK-AES-I provides dedicated AES/EBU input expansion for compatible systems. The card is also designed to support hot-plugging, providing convenient installation and servicing within supported equipment. Its compact card-based design allows AES/EBU input capability to be integrated directly into the compatible DiGiCo hardware. With four stereo inputs, flexible sample rate conversion, and professional XLR connectivity, it provides a practical expansion solution. The D-RACK-AES-I is an appropriate choice for users requiring additional AES/EBU digital input capacity.
