McDSP APB-8 Analog Processing Box

8-channel analog processing box combining the convenience of digital signal processing with the incomparable sonic quality of premium analog components

Product Description

The McDSP APB-8 Analog Processing Box is an eight-channel version of the APB-16. Other than channel count, all functionality and capability is identical in the APB-16 and APB-8. The units can be combined on the same Thunderbolt bus, in any combination, up to five (5) units, for up to 80 channels of programmable analog processing. Both Thunderbolt 2 and Thunderbolt 3 connectivity is supported in the APB-8 and the APB-16.


The Analog Processing Box comes with an array of powerful signal processors, including compressors, mastering-grade limiters, transient enhancers, multi-channel processing and more. Each plug-in routes audio to the groundbreaking APB hardware device, where it’s processed by authentic analog components. And just like any other plug-in, you can save your settings as a preset, automate parameters, and recall sessions in an instant. Finally, the solution to analog recalls is here!

Compatible with macOS and Pro Tools 12.x or later, the APB-8 lets you turn your computer into a world-class analog recording studio. Process tracks with sample-accurate automation using state-of-the-art 32-bit digital audio converters.


The APB-8 includes six cutting-edge dynamics processors. The C673-A compressor is based on McDSP’s C670 and C671 modules from the McDSP 6000 series with a custom saturation circuit.

The Moo Tube compressor delivers soft, warm tube compression based on decades of software modeling. The El Moo tube limiter uses a similar design with an adjustable all-analog saturation stage.

The Chickenhead compressor offers a one-of-a-kind compression algorithm that utilizes high-end analog components and aggressive saturation for a punchy, plucky sound.

The L-18 limiter offers pristine analog limiting perfect for any genre. Whether you need heavy peak limiting, subtle bus compression, or surgical transient shaping, the L-18 is your new go-to limiter. And if you’re looking for a versatile compressor, the C-18 is packed with powerful features. Based on McDSP’s classic CompressorBank plug-in, the C-18 features an upgraded BITE control. An advanced AUTO feature offers program-dependent response times, making the C-18 a solid choice for individual channels, bus compression, or even parallel processing.

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.

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.
