Industry use
Three versions. One platform.
Made in Finland. Certified for safety.
The ADA 8x8 G4 runs on Linux and uses advanced DSP for all audio inputs and outputs, with per-channel delay for precise zone control. Its 32×32 digital matrix handles complex audio routing across up to 512 zones. An optional DANTE network audio interface (Brooklyn 3) provides 24×24 channels of IP-based audio distribution using standard Ethernet infrastructure.
Power amplification uses Class D GaN technology, delivering 95% efficiency with minimal heat output — a significant improvement over conventional amplifier designs. Up to four DPA224 amplifier cards can be installed in a single Core unit, with each card providing 2×240W output.
The built-in message player stores up to 128 pre-recorded WAV messages for automated announcements, emergency tones and evacuation instructions. Calendar and timer functions enable scheduled operations without external control systems. An open API allows integration with building management systems, fire alarm panels and third-party control platforms.
