9 CP9PRO+

With the CP-9 Pro+, Maxon has taken one of the most lauded compression circuits of all time and placed it in one amazing little stompbox, creating the most “effective” compressor yet!

More than a reissue, the CP-9 Pro+ features a completely redesigned circuit that is vastly superior to the original 1980’s model. The CP-9 Pro+ circuit is based around the patented low-noise DBX compression technology that is used in many high-end pro audio products. This circuit combines a high-quality VCA (voltage controlled amplifier) with an RMS (root mean square) sensor, providing a natural attack response while maintaining an extremely low noise floor generally not found in floor-based units.

The CP-9 Pro+ has Threshold, Ratio, and Gain controls that are extremely interactive and allow for a variety of useful applications for the unit. With a maximum compression Ratio of ?:1 (no increase in output level, regardless of level) the Pro+ can be used as a limiter to balance volume levels. At medium Threshold settings a variety of compression effects from “pinched” notes to shimmering, sustained arpeggios can be achieved by simply varying the Ratio and Gain knobs. With a maximum Gain of 30 dB and Threshold set at 1:1 (no compression) the Pro can also be used as a clean booster to slam the front end of your amplifier or other effects units. The CP-9 Pro+ has the highest Gain available from a pedal compressor, making it possible to achieve a balanced output at any compression setting. A Reduction status LED accurately displays the degree of the compression effect for the user to see when the unit is engaged.
