API 2500 Stereo Bus Compressor
Discrete stereo bus compressor with API 2520 Op-Amp, variable threshold between -20 dBu and +10 dBu, and selectable ratio, attack and release times
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.
FEATURES:
- API 2520 Op-Amp
- Variable threshold between -20 dBu and +10 dBu
- Selectable ratio, attack and release times
- Patented THRUST selectable high-pass filter before RMS detector

Thrust Circuit is Amazing!

The Drum Bus magic box!!!!!!!!!! My drum tracks always lacked that punch, loudness, and vibe of professionally mixed songs. After I got this box on the reccomendation of my VK rep, things done changed! I've been using my UA plug ins for individual compression and EQ on the kick and snare and then mixing all the drums tracks out to a stereo bus/hardware insert, through the 2500 and back in. It's been a game changer for me.

Buyer's Guide: Compressors/Limiters
05.23.2019Read MoreCompressors and limiters are some of the most important and versatile tools that any audio engineer can use. Virtually every modern recording uses compression somewhere in the chain of tracking, mixing, and mastering. This ubiquity makes them valuable but also creates confusion when considering the many choices in the marketplace. To help straighten that out, we’ll discuss the main types of compressors and the terminology that explains their usage.The purpose of a compressor is to even out the audio signal in order to tame loud transients and bring up lower amplitude material. Compressors were born out of necessity to fill that very straightforward role, to protect radio transmitters from overly hot signals, and to keep recordings in a narrower dynamic range that was easier to reproduce on tape or record.
