Description

The API Audio 2500 is the ultimate stereo bus compressor that serves as the secret weapon for both professional and aspiring audio engineers. This versatile dual-channel signal processor is designed for tracking, mixing, and mastering, offering an unparalleled level of control over the sonic character of your mix. Whether you're aiming for a tight, punchy bottom end or a smooth, cohesive blend, the API 2500 delivers with finesse.

At the heart of the 2500 is API's patented THRUST circuit, which injects a chest-hitting low-end impact into your mix. You can effortlessly switch between "old" feedback compression and "new" feed-forward compression styles, allowing for dynamic and adaptable processing. The unit features a soft, medium, or hard knee, letting you tailor the compression curve to your precise needs. The auto-makeup gain feature ensures consistent output levels as you adjust thresholds or ratios, providing a seamless mixing experience.

The 2500 also boasts a Mix/Blend circuit, a feature first seen in the limited 50th Anniversary Edition, that offers cross-fader or parallel mixing of compressed and uncompressed signals. This enables you to blend your signals exactly as desired, without losing any sonic detail. With a fully balanced design and front panel VU meters, the 2500 ensures fidelity and precision, making it an indispensable tool in any studio setup.

  • Dual-channel design for stereo or dual-mono operation
  • API's patented THRUST circuit for enhanced low-end punch
