API 2500 Discrete 2 Channel Stereo Buss Compressor

API 2500 front view
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 the 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, 1176 and Fairchild. 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 really like this API 2500 Stereo Buss Compressor! Upon first listening to it I was very impressed... and have to say it one of the best 2 buss compressors I have heard. It has personality without being over done... but wass not "too clean" either. It has more than one sound.. which is a nice feature and very useful. I A/B'd the API 2500 against my 33609 (Discrete, Shep) as was shocked to hear the API was much more musical and the low end was tighter and more present. Over all the API 2500 sounded much better. If you could ony afford one stereo buss compressor... I suggest the API 2500. If your budget affords you the luxury of having more that one 2 buss compressor... this should still be one of them... you can not get this sound anywhere else and it sounds great."
