🎬 Reference-Grade Immersive Processing for Dolby Atmos, DTS:X Pro & Auro-3D

The ISR Fusion supports every major 3D audio format with full-bandwidth, high-precision decoding:

• Dolby Atmos with complex multi-layer speaker layouts
• DTS:X Pro enabling up to 30 discrete rendering channels
• Auro-3D with Voice of God channel
• IMAX Enhanced playback support

StormAudio’s signature StormXT algorithm intelligently expands immersive layouts by distributing audio objects into additional speakers with natural, seamless integration—preserving artistic intent while enhancing envelopment.

🔊 High-Current, Ultra-Low-Distortion Amplification

The Fusion integrates a powerful multi-channel amplifier stage engineered for clean transient response, wide dynamic headroom and ultra-low distortion. Its refined power supply and efficient thermal architecture ensure stable performance even under demanding cinema loads.

• High-current Class AB amplification
• 20 powered channels for direct-to-speaker drive
• Silent thermal design for discreet installation
• Optimized damping factor for authority and control

From deep bass steering to crystal-clear spatial detail, this amplifier section delivers the visceral dynamic range required by modern blockbuster soundtracks.

🎚️ Dirac Live Active Room Treatment (ART) – Industry-Leading Calibration

StormAudio is the first manufacturer to integrate the groundbreaking Dirac Live ART platform, which uses all speakers in the room to actively control low-frequency behaviour. This results in:

• Tighter, more uniform bass across all seating positions
• Reduced room resonance
• Improved transient accuracy
• Seamless integration between subwoofers and main speakers

Alongside ART, the ISR Fusion supports Dirac Live Full Bandwidth, providing correction from 20 Hz to 20 kHz with phase optimization and filter precision unmatched in the category.

🏛️ ESS-Based Audiophile DAC Architecture

The ISR Fusion uses premium multi-channel ESS digital-to-analog converters, delivering:

• Ultra-low noise floor
• High dynamic range
• Exceptional channel separation
• Phase-coherent reproduction

The result is a sonic presentation that is transparent, articulate, and effortlessly dynamic, even in large-scale speaker configurations.

⚙️ Modular Architecture – Designed for Longevity

Like the ISP processors, the ISR Fusion uses a fully modular hardware platform, ensuring future updates can be installed without replacing the entire unit. This includes:

• Video board upgrades
• Audio module upgrades
• Firmware-based feature expansion

The ISR Fusion is built with future-proofing at its core, protecting your investment for many years.

🔧 Installation-Ready for Premium Home Cinemas

• 20 onboard amplifier channels for large Atmos / DTS:X Pro layouts
• Advanced bass management for up to 4 independent subwoofer channels
• Extensive control integration (IP, RS232, automation)
• Web UI with intuitive calibration and monitoring tools

The ISR Fusion is ideal for premium theaters where powerful decoding, ample amplification and advanced correction must coexist in a single, space-efficient chassis.
