API 2500+ Stereo Bus Compressor

Updated version of the 2500 stereo bus compressor featuring expanded variable threshold between -20 dBu to +20 dBu, new blend/mix function, and proprietary 2520 op-amps
MFR# 2500+

Product Description

The API 2500+ Stereo Bus Compressor allows adjustment of sonic qualities to alter the punch and tone of the stereo mix. The 19-inch, rack-mountable unit features a dual-channel design that can be configured for stereo compression or for use as two separate units via a single compression setting.

Among the many qualities which make the 2500+'s unique is its use of API's patented THRUST circuit for a chest-hitting, punchy bottom end. Another distinctive feature of the 2500+ is its selectable "old" or "new" compression, with the old style using the "feed back" type of compression found in the API 525, and the new style using the "feed forward" type in which the compressor side chain is fed directly from the unit input. Additionally, the output stage of the 2500+ offers an auto-makeup gain button that permits the user to vary the threshold or ratio while automatically maintaining a constant output level.

Added to the 2500+ is the Mix/Blend circuit. First featured in the limited production 50th Anniversary Edition, Mix/Blend control provides either cross fader or parallel mixing of the compressed and uncompressed signal. Three different user settings are offered:

  • OFF - compressed signal only
  • X (Cross) - allows the MIX control to adjust between 100% uncompressed to 100% compressed – increasing one, while decreasing the other
  • || (Parallel) - allows the MIX control to dial in compressed signal to blend into the uncompressed signal, (which remains the same)

The 2500+ ensures fidelity with its fully balanced design and two front panel VU meters showing input, output and gain reduction levels. The 2500+ features API's industry exclusive five-year parts warranty and offers the user the reliability, sonic excellence and long life characteristic of all API products.

Features:

  • API 2520 Op Amps
  • Expanded variable threshold between -20 dBu to +20 dBu
  • Selectable ratio, attack, and release times
  • Patented THRUST filter with 3 settings for frequency dependent side chain control 
  • Variable link between left and right channels
  • Old "feed back" and new "feed forward" compression
  • Soft, Medium, or Hard knee for easy to sharp compression
  • Auto or manual gain make up
  • 1/4" balanced side chain inputs
  • Output clips at +32 dBu
  • New Mix/Blend circuit
  • "Over Threshold" LED illuminates when input audio crosses the set threshold
  • Stereo analog meters to show input level, output level, and gain reduction
  • Full hard-wired relay bypass

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.
