The Heritage Audio OST-4 is an enclosure for up to 4 lunchbox style 500 series modules, both from Heritage and other manufacturers. What makes the enclosure special is the company's "On Slot Technology," which leverages the latest generation of power electronics to provide a supply of power on a "per slot" basis. Each slot has its own power supply linear regulation stages, which makes each module isolated from the rest. This helps address some of the issues encountered when modules of different kinds share one common power supply. Instead, they simply share the same heavy gauge steel enclosure.
On the side of each connector, each slot features test LEDs for checking the correct power operation (red for +16V, green for -16V). The power capability of the unit is 400mA per rail per slot maximum, with an overall of 700mA per rail, whichever is reached first. The total available phantom power is 80mA. The heavy gauge steel enclosure has an aluminum front panel and was constructed in the United Kingdom.
