4-Slot 500 Series Rack with Per-slot Power Handling and Channel Linking
The Heritage Audio OST-4 v2.0 is a 500 Series chassis that accommodates up to four modules. The OST-4 v2.0 features On Slot technology, which leverages next-gen power electronics to handle module power requirements on a per-slot basis. In the OST-4 v2.0, each slot is spec’d with its own linear power-supply regulation stage, keeping each module isolated from the rest. Modules only share the metal enclosure. Sweetwater engineers agree that this is an effective method for eliminating common issues that can occur when sharing power between modules of different brands. An exciting feature of this second-generation model is the Link feature, which allows each channel to be linked to its next neighboring channel at the press of a rear-panel button — no patch cables required.

Don’t merely house your 500 Series modules — optimize their performance
500 Series racks are a fact of life in the modern pro studio. So it only makes sense to go for one that is durable, well-priced, and compatible with all your 500 Series modules. But more importantly, one that enables you to get the cleanest and best performance from every module you own. The OST-4 v2.0 checks all these boxes; it’s an ideal solution for housing 500 Series modules in an enclosure that allows them to achieve their peak sonic potential, in a rugged, portable enclosure that won’t blow a hole in your budget.
Safer, cleaner, and more compatible
Many experienced engineers are aware of certain power-hungry Class A or vacuum tube based modules which could cause banks of 500 Series modules to “brown out” or cease to function, or that simply would simply refuse to work in many standard enclosures. The OST-4 v2.0 offers the widest range of compatibility with all 500 Series modules, ensuring both that demanding modules receive the power they need, and that modules in adjacent slots remain unaffected. You can think of the Heritage Audio OST-4 v2.0 as an upscale condo building, where each one of your 500 Series modules has its own luxury penthouse.
The power of On Slot technology
In the world of 500 Series racks, Heritage Audio’s On Slot technology (OST) sets the OST-4 v2.0 apart. Thanks to OST, the OST-4 v2.0 is able to deliver hefty current: up to 1.6A per rail, or 400mA per rail per slot, whatever is reached first. Maximum phantom power current is rated at 140mA. Each slot has its own red (+16V) and green (-16V) test LEDs, located aside the slot connector, for convenient power-status checking. With its heavy-gauge steel construction and classic RAF blue-gray livery, the OST-4 v2.0 features Heritage Audio’s typical military-grade build quality for years of unflagging professional duty.
