Delivering unmatched power, flexibility, and efficiency, the Parasound ZM12 is a 12-channel, 6-zone amplifier designed for large-scale audio installations. Built to handle complex, multi-room systems, the ZM12 packs robust power into a compact 2RU chassis, making it perfect for custom installations, commercial audio, or multi-zone residential systems.
Combining a Class AB input stage with premium Class D output modules, the ZM12 is stable down to 2 Ω and engineered for both performance and reliability. It offers independent level control for each channel, A/B speaker outputs (up to 24), and multiple trigger and input options to integrate seamlessly into any automation or distribution system. Each zone supports its own auto-on trigger and can switch between stereo or summed mono, giving installers flexible control over how the system is configured.
Whether you’re powering a home theater, restaurant, retail space, or whole-home audio system, the Parasound ZM12 delivers consistent, high-performance sound with minimal heat, low power consumption, and exceptional build quality.
