API 2500 (Demo Deal) – No Longer Available

Discrete stereo bus compressor

Product Description

The API 2500 is a versatile stereo bus compressor that allows adjustment of sonic qualities that can alter the punch and tone of the stereo mix. The 19" rack-mountable unit features API's patented "thrust" circuit for a chest-hitting, punchy bottom end. With its dual-channel design, the API 2500 is set up for stereo compression, but can also be used as two separate units via a single compression setting. The 2500 boasts a range of parameters that make it incredibly musical.

API pushes the envelope of flexibility further with selectable "old" or "new" compression. The old-style uses the feedback type of compression found in the API 525, Universal Audio 1176, and the Fairchild 660/670. The new style uses a feed-forward type, similar to other popular compressors.

The output stage features API's auto-makeup gain button, permitting the user to vary the threshold or ratio while automatically maintaining a constant output level. Fidelity is ensured with an all-discrete, fully balanced design, and two front panel VU meters show input, output, and gain reduction levels.

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.

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.

Thank you so much! Vintage King has been so fair and easy to work with. I can't thank you enough. It feels good to trust such a hefty purchase to folks who are so helpful and knowledgeable. Vintage King is a sound designers dream store.

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.
