Mercury G810 Rack System II: High-Performance 500 Series Power for the Budget-Conscious Studio

The Mercury G810 System II provides the same "bulletproof" power architecture and heavy-duty construction as the flagship System I, but in a more streamlined, budget-friendly package. Designed by the experts at Mercury Recording Equipment, this 10-slot rack is engineered to solve the power and stability issues common in standard 500 Series enclosures. By focusing on a refined I/O set and sequential linking, System II offers an entry point into the Mercury D Series ecosystem without sacrificing the elite power regulation that protects your investment.

The Gold Standard in Power and Regulation

The foundation of any great signal chain is its power. System II utilizes Mercury's proprietary technology to ensure your modules perform at their absolute peak:

• Mercury Power Regulation Circuit (PRC): Unlike standard racks, the G810 features individual regulation for every slot. This isolates each module, preventing power-hungry units from sagging the rails or introducing noise into adjacent channels.
• Mercury Soft Start Circuit: Protects your gear by gradually ramping up voltage during power-on, eliminating the dangerous "turn-on thump" that can damage both your modules and your studio monitors.
• External PSU-1 Linear Power Supply: Ships with a robust, low-noise linear supply designed specifically for professional audio. This ensures massive headroom and dynamic reserve that exceeds VPR Alliance specifications.
• Stable Dynamics: Whether you are running a single preamp or 10 power-hungry compressors, the G810 provides the current necessary to keep your audio clean and punchy.

Streamlined Connectivity and Reliability

System II is built for efficiency and high-density setups, making it the perfect choice for modern hybrid studios:

• Optimized I/O Layout: Features high-quality DB25 (D-Sub) connectors for Channels 1–8 for fast, cost-effective integration with your patch bay or interface. Dedicated Gold Pin XLR connectors are provided for Channels 9 and 10.
• Sequential Link Switch: Easily link adjacent modules (1-2, 3-4, etc.) for stereo operation with the flick of a switch, provided your modules support the link feature.
• Custom Ground Lift: Three-mode ground selection (Ground Lift, RF, and Ground) ensures hum-free operation in even the most challenging electrical environments.
• Tabletop or Rackmount: While it ships as a 3U rackmount unit, it can be easily converted to a portable tabletop configuration for mobile recording.

Built Like a Tank, Ready for the Future

Hand-built in the USA, the G810 System II is designed to be a permanent centerpiece of your studio:

• Heavy-Duty Construction: A durable steel chassis and thick aluminum rack ears make this rack road-worthy for live use while looking beautiful in a studio rack.
• Future-Proof Slots: Slots 9 and 10 are designed to host any 500 Series module or upcoming specialty Mercury G8 modules for advanced routing and summing.
• No Compromise Components: Mercury avoids the shortcuts of mass-market racks, opting for premium components that provide a solid foundation for your audio signal.

Key Benefits

• Elite Power for Less: Get the same industry-leading power regulation as the System I at a more accessible price point.
• Individual Slot Isolation: Protects your modules from faults and noise generated by other gear in the rack.
