Product lists can be submitted to HHB for a packaged quotation
The API 2500 Stereo Bus Compressor is a 19-inch, rack-mountable unit that offers a dual-channel design that can be configured for stereo compression or for use as two separate units via a single compression setting. It employs API’s patented THRUST circuit for optimised bottom end. Users can choose between “old” or “new” compression. The old style uses the “feed back” type of compression found in the API 525, while the new style uses a “feed forward” type in which the compressor side chain is fed directly from the unit input. The output stage exhibits an auto-makeup gain button that permits the user to vary the threshold or ratio while automatically maintaining a constant output level. Two front panel VU meters showing input, output and gain reduction levels.
