SPL Transpressor

Compressor and transient processor
MFR# 1080

Product Description

The SPL Transpressor is the first processor that combines the two most important dynamic processing techniques: compression and level-independent treatment of transients. By blending these techniques in a single path, SPL aims to void the previous limitations of dynamic processing.

The Transpressor is designed as a single channel unit but you can always couple two in order to do some stereo processing. Our intent to offer a flexible and powerful audio processing tool, based on the interaction between transient processing and compression, is made evident by the freedom to place the modules in any order in the signal path. That way you can compress attacks that have been heavily amplified by the Transient Designer more precisely or enhance the transients once they have been compressed.

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.
