Heritage Audio 8 Slot 500 Series OST Enclosure with 10 Channel mixer

The Heritage Audio MCM-8 II is a high-quality 10-channel professional audio mixer designed for seamless integration with 500 Series modules, offering robust features for mixing and processing sound in studio or live environments.

MCM-8 is an eight-slot chassis designed for 500 Series modules, equipped with a ten-channel mixer. Each of the eight slots includes its own linear power regulation stage, ensuring that a complete rack of various modules operates reliably.

On the back of the unit, you'll find both XLR and D SUB 25 connectors for inputs and outputs, providing versatile connectivity options. Additionally, the MCM-8 includes an extra stereo input, allowing you to connect multiple MCM-8 units or integrate signals that don’t need further processing from 500 Series modules.
