Heritage Audio OST-6 Enclosure for 500 Series Modules (6-Slot)
Express Checkout


The Heritage Audio OST-6 is a 6-slot enclosure designed to provide stable power for up to six 500 Series modules for musicians and recording and mixing engineers in mobile-production rigs and home, project, and commercial studios. Its On-Slot Technology enables per-slot linear regulation stages, which isolate the slots and avoid power sharing between modules. Each slot features test LEDs—red for +16V and green for -16V—to indicate proper power status.

It supplies up to 140mA of phantom power and utilizes gold-plated XLR jacks and Edge connectors. Made in the EU with a heavy-gauge steel enclosure and aluminum front panel, it yields tour-worthy durability and sports a built-in carry handle for easy transport. The OST-6 can be mounted in 3 RU of a standard 19” equipment rack via the included rack ears. It ships with the required external power supply.
