API 525

Feedback compressor in the style of the Urei 1176 with variable Threshold and Output levels and at the same time a “Ceiling” control which changes the Threshold and Make-up Gain simultaneously, giving precise control of the compression while keeping the output constant.

• Exact reissue of API’s original 525 from the early 70’s
• Peak detecting “feedback” compressor/limiter
• Variable Threshold and Output levels
• Unique “Ceiling” control combines key functions
• Analog VU meter for monitoring gain reduction
• 4 Switchable release modes
• De-Ess function
• Traditional API fully discrete circuit design
• Active Balanced Input/Output
• Hardwire bypass
