ADA 8x8 G4 System Unit
EN54-Certified Voice Evacuation and Public Address System for Any Scale
The ADA 8x8 G4 is the central system unit of the Audico AVEC G4 voice evacuation, public address and background music platform. It provides centralised control and management for all connected components — from a single-zone retail installation to a fully redundant multi-site voice evacuation system across hundreds of zones. Available in three versions — Core X, Core I and Core II — the ADA 8x8 G4 scales to match the exact requirements of the installation, without oversizing or compromise. Designed and manufactured in Finland under ISO 9001 certified processes.

Industry use
Ideal for any application requiring secure, multi-zone public address or EN54-certified voice evacuation — schools, hospitals, shopping centres, transport infrastructure, industrial facilities and maritime vessels. Scales from 8 to 512 zones within a single system.
Three versions. One platform.
Core X for compact installations such as small retail and schools. Core I for mid-sized buildings including offices and healthcare. Core II for the most demanding projects — shopping centres, airports and large passenger vessels. All three versions share the same architecture, software and product family.
Made in Finland. Certified for safety.
Designed and manufactured in Finland under ISO 9001 and ISO 14001 certified processes. EN 54-16 and EN 54-4 certified. EN 60945 compliant with DNV and Bureau Veritas type approval for maritime use. RoHS compliant.
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.
Core Versions
Core X — Compact installations
The entry-level configuration for straightforward PA requirements. Suited to small retail environments, schools and any site where simplicity and cost-efficiency are the priority. Delivers essential amplifier functionality with the full AVEC G4 feature set.
Core I — Mid-sized buildings
Designed for offices, schools, community buildings and small healthcare facilities. Balances amplifier power and channel count to deliver reliable performance across multiple zones without unnecessary complexity.
Core II — Large and demanding installations
Built for shopping centres, airports, transport terminals and large passenger and cruise vessels. Provides maximumamplifier power with up to 4 DPA224 amplifier cards per unit,
