525A FET Compressor

500 Series Module

From API:

Since the early 1970s and the subsequent re-issue over 20 years ago, the 525 Discrete Compressor has become one of the most trusted vintage-style compressors in the industry. Building on the powerful core circuitry of the original 525, the new 525A maintains the discrete audio path and expands the feature set for even more applications in the modern studio. It artfully combines API’s proprietary transformers, 2510 and 2520 opamps, retaining the sonic characteristics of the original while exhibiting the reliability, long life, and uniformity which is characteristic of all API products.
