Revamp your audio experience with the API 2500+ Stereo Bus Compressor. This exceptional unit empowers you to sculpt the sonic character of your stereo mix by fine-tuning punch and tonal qualities. Designed for versatility and precision, this 19-inch rack-mountable marvel boasts a dual-channel configuration, providing the flexibility to employ it either as a stereo compressor or as two independent units using a unified compression setting.

What sets the 2500+ apart is its arsenal of distinctive features, headlined by API`s patented THRUST® circuitry that delivers a chest-thumping, impactful low-end. Further enhancing its prowess is the option to toggle between "old" and "new" compression styles. The "old" style channels the timeless "feed back" compression reminiscent of the revered API 525, while the "new" style employs the cutting-edge "feed forward" approach where the compressor side chain originates directly from the unit input. Enriching the offering is the output stage with an auto-makeup gain button, seamlessly allowing you to modify the threshold or ratio while effortlessly maintaining a consistent output level.

Freshly integrated into the 2500+ is the innovative Mix/Blend circuit, making its debut in the esteemed 50th Anniversary Edition. The Mix/Blend control introduces the option for crossfading or parallel mixing of the compressed and uncompressed signals. Choose from three user settings:

• OFF - Exclusively compressed signal
• X (Cross) - Gradual mix adjustment from 100% uncompressed to 100% compressed, enhancing one as the other diminishes
• + (Parallel) - Blend compressed signal into the unaffected signal, preserving its integrity

The 2500+ ensures sonic fidelity with its fully balanced architecture and dual front-panel VU meters displaying input, output, and gain reduction levels. Backed by API`s industry-exclusive five-year parts warranty, the 2500+ guarantees reliability, sonic excellence, and enduring performance – the hallmark of all API products.
