Heritage Audio OST4v2 4-slot 500 Series Chassis

The OST-4 V2.0 500 Series enclosure from Heritage Audio is designed for racking any and all 500-series modules and devices, including ‘double wide’ modules and even the most demanding class-A and vacuum tube designs. The enclosure features Heritage Audio’s On Slot Technology, providing maximum protection, filtering and isolation to each channel. While most 500-series enclosures on the market have a relatively simple power supply design essentially feeding every channel in parallel, each channel of the OST-4 enclosure has its own power supply, individually regulated and isolated from the rest. This ensures that every 500-series module installed will perform at its peak potential, and that no faulty module will compromise the performance of another. In addition to reducing interference, many 500-series devices actually exhibit lower self-noise and better performance when racked in the OST-4 V2.0 enclosure, specially mic preamps.
