OST 4 V2.0

The OST-4 V2.0 500 series enclosure 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 OST-4 V2.0 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 V2.0 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 ‘power
hungry’ or even a 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, especially mic preamps.
