Heritage Audio OST4 v2

The small but mighty OST4 v2 from Heritage Audio is a 500 series case which provides clean, noise-free power, and is ideal for someone just starting with 500 series modules or in need of some extra slots in an existing setup. OST is short for On Slot Technology, which is Heritage Audio's specially designed power supply system that keeps each module regulated in isolation from the others, so although they share an enclosure, noise crosstalk between modules is kept to a minimum to maintain clear audio output. Additionally, version two of this case adds Link switches to the audio ports on the rear, allowing easy configuration of favorite combos or multichannel modules. Don't be deceived by the small size, for Heritage Audio designed the OST4 v2 to provide the same level of quality designed power and audio signal flows as its larger counterparts.
