10-Slot 500 Series Rack with Per-slot Power Handling and Channel Linking

The OST-10 V2.0 500 series enclosure is designed for racking any and all 500-series modules and
devices, including ‘double wide’ modules and even the most demanding Class A and vacuum tube
The OST-10 V2.0 enclosure features Heritage Audio’s On Slot Technology, providing
maximum protection, filtering, and isolation to each channel. While most 500-series enclosures on the
market have a relatively simple power supply design essentially feeding every channel in parallel, each
channel of the OST-10 V2.0 enclosure has its own power supply, individually regulated and isolated from
the rest. This ensures that every 500-series module installed will perform at its peak potential, and that
no ‘power hungry’ or even a faulty module will compromise the performance of another. In addition to
reducing interference, many 500-series devices actually exhibit lower self-noise and better performance
when racked in the OST-10 V2.0 enclosure, specially mic preamps.


A new and exciting feature in the V2.0 model is the Link feature, allowing each channel to be linked over to the next at the push of a button (via back panel), no patch cables required!
As with all Heritage Audio products; the 500 Series OST-10 V2.0 enclosures are built utilizing the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners — all at the Heritage Audio headquarters in Madrid-Spain.

The 500 format is here to stay, be set up for it!
With the popularity of 500 Series modules showing no signs of waning, it makes more sense than ever for both professional and home studios alike to have plenty of slots available to house their growing collection of new and old 500 Series modules.

Don’t just house your 500 series modules, bring out the best in them!

While a 500 Series enclosure may not seem like the most exciting thing in the studio, you’ve got to have them. It only makes sense to get one that is durable, not overpriced, compatible with any 500 Series module you may have, and most importantly, one that will bring out the cleanest and very best performance in your gear.
With the OST-10 V2.0, you have a perfect solution for housing up to ten 500 Series modules in an enclosure which brings out the best of their sonic potential, in a portable, rugged
enclosure that won’t break the bank.

Safer, cleaner, 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 not function, or that simply would not work in some standard enclosures.
The OST-10 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 adjacent modules remain unaffected.
Your 500 Series modules have simply never had it so good!
