API 2500 Stereo Bus Compressor
Good used condition with some light visible signs of use, including minor scratching, marks, rack-rash etc. Supplied serviced and in perfect working order. No original box or accessories.
The API 2500 Stereo Bus Compressor allows adjustment of sonic qualities to alter the punch and tone of the stereo mix. The 19-inch, rack-mountable unit features a dual-channel design that can be configured for stereo compression or for use as two separate units via a single compression setting. Among the many qualities which make the 2500 unique is its use of API’s patented THRUST circuit for a chest-hitting, punchy bottom end. Another distinctive feature of the 2500+ is its selectable “”old”” or “”new”” compression, with the old style using the “”feed back”” type of compression found in the API 525, and the new style using the “”feed forward”” type in which the compressor side chain is fed directly from the unit input. Additionally, the output stage of the 2500+ offers an auto-makeup gain button that permits the user to vary the threshold or ratio while automatically maintaining a constant output level.
