API 525A Discrete Compressor Module
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.
Features:
- NEW – Variable Attack adjustable from 15 microseconds to 15 milliseconds
- NEW – 7 selectable Release Modes (.05 to 2.0 Seconds)
- Unique Ceiling Control simultaneously combines Threshold and Make-up Gain
- Classic 1970s style analog gain reduction VU meter
- Traditional API discrete audio path circuit design
- Equipped with 2520 and 2510 opamps
- Proprietary API output transformer
- Balanced Input/Output
- Hardware Bypass
“I have always loved the 525 Compressor, but wished that I could have more control over the attack and release times to make it more useful on things like drums, etc,” commented Grammy Award-Winning Engineer and API Technician Paul Leavitt. “The new features built into the 525A really make this classic FET compressor an even more indispensable tool in the studio.”
