Heritage Audio OST4 V2 500-serien rack
New to the V2.0 model is the Link feature, which allows each channel to be linked to the next channel at the push of a button — no patch cables required! And of course, each channel still features the On Slot Technology used in all of Heritage Audio’s 500 Series enclosures, now almost three times as powerful as its predecesor.
With On Slot Technology (OST), each channel of the enclosure has its own power supply, independently regulated, filtered, and protected. This ensures the highest degree of isolation and consistency in performance. 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. OST enclosures offer 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. Aside from safety and compatibility, OST
enclosures ensure the highest level of performance and lowest self-noise for your 500 Series modules, specially mic preamps. With a heavy gauge steel chassis, a rugged finish in Royal Air Force Blue-Gray, and as an audiophile design, your 500 Series modules have simply never had it so good. Like all Heritage Audio products, the OST V2.0 enclosures take advantage of the latest in manufacturing technology to offer an unprecedented value without compromising audio quality — all built at the Heritage factory in Spain.
The Heritage Audio OST-4 is an enclosure for up to 4 lunchbox
style 500 series modules, both from Heritage and other manufacturers.
What makes the enclosure special is the company's "On Slot Technology,"
which leverages the latest generation of power electronics to provide a
supply of power on a "per slot" basis. Each slot has its own power
supply linear regulation stages, which makes each module isolated from
the rest. This helps address some of the issues encountered when modules
of different kinds share one common power supply. Instead, they simply
share the same heavy gauge steel enclosure.
On the side of each
connector, each slot features test LEDs for checking the correct power
operation (red for +16V, green for -16V). The power capability of the
unit is 400mA per rail per slot maximum, with an overall of 700mA per
rail, whichever is reached first. The total available phantom power is
80mA. The heavy gauge steel enclosure has an aluminum front panel and
was constructed in the United Kingdom.
