Description

Edit description

The Monster Power PRO 3500 Rack PowerCenter is the unsung hero of any professional or home recording studio. More than just a standard surge protector, this powerhouse integrates patented Clean Power filter circuitry, designed to eliminate noise that ordinary surge protectors cannot handle. Whether you're running digital or analog gear, you’ll benefit from its revolutionary noise isolation technology, which keeps your sound clear and true by separating digital and analog filtered outlets. This means any noise picked up from shared components has to overcome two layers of filtration before it reaches your equipment, resulting in an impressively low noise floor.

The Monster Power PRO 3500 doesn’t just stop at noise reduction. With its Tri-Mode circuitry, you receive both audible and visual alerts for comprehensive surge protection, ensuring your gear remains safe from unexpected power spikes. The high-sensitivity digital meter lets you keep an eye on available voltage and current demand, providing insights into your power usage. A thoughtfully designed three-stage sequenced AC power turn-on and turn-off feature further protects your equipment from overloads.

Built with studio professionals in mind, the PRO 3500 offers a component-width chassis with built-in rack mounts and handles for easy integration into any setup. And with a 2775-joule rating, your equipment is shielded by a high level of surge protection.
