HERITAGE AUDIO OST-4 V2.0 | 4-slot 500 Series Rack With Power Handling & Channel Linking

OST-4 v2.0

Enclosure for 500 Series Modules

House all your prized 500 Series gear in the Heritage Audio OS-4 v2.0 Enclosure, a high-quality 500 Series rack with four slots. This enclosure can handle double-wide modules, as well as power-hungry Class-A and vacuum tube designs. With Heritage Audio's On Slot Technology, the OS-4 v2.0 ensures that each channel offers a high degree of protection, isolation, and filtering.

Each rail slot provides 400mA of current, for a total of 1.6A. Up to 140mA of phantom power can be supplied. Each of the slots in this rack essentially has its own power supply, one that is regulated individually and isolated from the others. This ensures that no one power-hungry unit will ruin the fidelity of another.

Heritage Audio also assures you that many 500 Series units will perform better when housed in the OS-4 v.20. You should note, and be able to measure, a lower degree of self-noise in 500 Series preamps, for example.

On the rear of the unit you'll find four XLR inputs and four XLR outputs, as well as a five-pin XLR power input jack. All XLR jacks are gold-plated. A major addition to this series of rack enclosures is the link feature, which automatically feeds one channel into the next on the panel with the push of a button. Now, you no longer need to use patch cables if you're outputting signals in series. Simply press the link button between two slots, and one will automatically feed the other.
