Heritage Audio OST-8 ADAT 500 Series Rack

8-slot 500 series rack with ADAT output designed to rack any and all 500 series modules featuring On Slot Technology


Product Description

Maximize the potential of your audio interface with Heritage Audio’s OST-8 ADAT 500 Series Rack. Heritage Audio created the OST-8 ADAT 500 Series Rack as a direct response to customer requests to incorporate an ADAT output into the trusted manufacturer’s designs. This eight-slot 500 Series enclosure incorporates a premium converter, ensuring that capturing, processing, and digitizing high-quality signals is fast and easy. Sturdily built with gold plated XLR connectors and input / output duplication on DB25 connectors, the OST-8 ADAT 500 Series Rack opens up a new world of possibility, clarity, and ease.

Heritage Audio’s tried-and-true On Slot Technology provides unmatched filtering and isolation for each of the OST-8’s slots, while additionally guaranteeing the cleanest, most protected environment possible for your modules. Every module in the OST-7 ADAT 500 Series Rack enjoys its own power supply, so you can rest assured they’ll be giving their best performances. The OST-8 even includes two indicator lights for each slot, so you’ll always know whether or not your modules are receiving proper voltage. The OST-8 has the widest possible range of compatibility with 500 series modules, supporting even ‘power hungry’ class A and vacuum tube designs.

The OST-8 ADAT 500 Series Rack has an incredible eight-channel converter. The built-in premium 24-Bit/192 kH ADC can operate as a Master unit or Slave to another, with correct syncing with its BNC connector guaranteed, so you can sync to WordClock and assure a stable conversion. Unique to the OST-8, you can individually select the input routed to the ADC on a channel-by-channel basis, giving you the opportunity to access more processing possibilities. Furthermore, Heritage Audio has included their “Link” button on the back of the rack, which allows you to internally connect one module’s output to the adjacent module, thereby erasing the need to deal with more patch cables. So don’t wait! Order your OST-8 today from Vintage King Audio!

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
