Audiotec Fischer Extension Card 2.0 – DIGITAL IN – additional digital inputs for DSPs
The Extension Card 2.0 – DIGITAL IN is a digital stereo input module for HELIX and MATCH DSP devices with an Extension Card 2.0 slot. It adds an optical and a coaxial S/PDIF input, so digital sources can be connected without analog conversion and the signal is processed entirely in the digital domain.
Only one source is processed at a time: the module switches automatically when it detects a digital audio signal, or a fixed source can be selected in DSP PC-Tool, where the inputs can also be configured as additional main inputs or as an AUX source.
Key Features
- Two digital inputs: optical and coaxial S/PDIF (stereo PCM only)
- Sampling rates: optical 28–96 kHz, coaxial 28–192 kHz
- High jitter immunity: low-jitter clock recovery for reliable transmission
- Input selection: automatic signal detection or manual selection in DSP PC-Tool
- Info LED: shows signal detection status
- Flexible routing: configurable as main inputs or AUX source
- Made in Germany: supplied with module-specific cover panel
Compatibility
- All HELIX and MATCH DSP devices featuring an Extension Card 2.0 slot
