The BA-DB44 is a compact digital audio processor with 4 analog inputs and 4 analog outputs, 4 × 4 Dante network channels and a USB-C sound card. It pairs high-performance A/D and D/A converters with a 32-bit floating-point DSP at 24-bit / 48 kHz for high-quality sound, full matrix mixing and easy-to-use control software. Powered by PoE or DC 12 V, it suits meeting rooms, video conferencing, places of worship, conference centres and public sound reinforcement systems.

Key features
- Compact digital audio processor with 4 analog inputs and 4 analog outputs.
- High-performance 32-bit floating-point DSP with all-digital processing.
- High-performance A/D and D/A converters, 24-bit / 48 kHz sampling.
- Dante network audio: 4 inputs and 4 outputs.
- Built-in AFC (feedback cancellation), AEC (echo cancellation), ANS (noise suppression) and automatic mixing.
- Comprehensive matrix mixing.
- Input channel processing: preamp, expander, compressor, auto gain, 5-band parametric EQ and ducker.
- Output channel processing: delay, crossover, limiter, 31-band graphic EQ.
- Per-channel phase and mute switches, plus 48 V phantom power on inputs.
