API 2500+ Stereo Buss Compressor The API 2500+ Stereo Bus Compressor is a versatile bus compressor, famous for its ability to add sonic character and personality. Whether its used on the mix bus, sub groups or on a parallel bus, the feature set of the 2500+ tailors for most needs.Among the many qualities which make the 2500+'s 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. Features API 2520 Op Amps Expanded variable threshold between -20dBu to +20dBu Selectable ratio, attack, and release times Patented THRUST® filter with 3 settings for frequency dependent side chain control Variable link between left and right channels Old "feed back" and new "feed forward" compression Soft, Medium, or Hard knee for easy to sharp compression Auto or manual gain make up 1/4" balanced side chain inputs Output clips at +32dBu New Mix/Blend circuit "Over Threshold" LED illuminates when input audio crosses the set threshold Stereo analog meters to show input level, output level, and gain reduction Full hard-wired relay bypass Specifications Rear Connectors: XLR input, 1/4" side chain, XLR output Input Impedance: 60K Ohms, Balanced Output Impedance: 75 Ohms, Transformer coupled, Balanced Maximum Output Level: +32 dBu Frequency Response: ±0.5dB 20Hz to 50kHz Signal to Noise Ratio: 120 dB Power Consumption: 28.8 Watts Size: 19" X 1.75" X 10.5" deep Size (Boxed for Shipping): 23.25" X 6.5" X 16" Unit Weight: 9.4 lbs.
