The PA20-CP is a sturdy, "walk up and go" powered mixer, guaranteed to deliver loads of weighty power from it's 'Constant Power' amplifier. These well thought-out mixers offer operational flexibility for any live sound situation and engineers of any experience.
Allen & Heath' years of real world experience with large format touring desks has resulted in many innovative touches being incorporated into the design of the PA Series of stereo live compact mixers. The range brings a classic, feature-packed pro audio design with the same superior build and sound quality to an even wider audience, so that now every aspirational performer or rental company supporting them can benefit from a truly professional system.
Walk up and go is a perfect description of the PA20CP mixer all the controls you expect are logically placed so that you stay in control under the pressure of any performance. The 4 band EQ on inputs and outputs and clever output routing are unique and will ensure you get the best out of the system, while features such as individual phantom power switches and SPDIF recording output add professional finishing touches. Add sparkling clarity to your performance with the superior sound quality of a PA Series mixer.
There is a digital SPDIF 2-track output available from a RCA phono socket for recording direct to digital media, such as PC soundcards, DAT and digital audio processors. The recording send can be switched pre-fade if desired.
4 Band Channel EQ - Another design innovation taken from ALLEN&HEATH’s flagship range, the 4 band input EQ is every bit a pro tool. The low [60Hz] and high [12kHz] bands have shelving response, while the high-midrange band is sweepable from 350Hz to 6 kHz. Low-midrange EQ has a bell response at 250Hz - a frequency chosen to provide reduction of ‘muddy’ sounds and enhance ‘warmth’.
The PA-CP versions contain a built-in amplifier, delivering an impressive 1 kiloWatt, able to run a regular stereo PA system with very little external equipment. Our objective was to produce a powerful, great sounding amplifier in a compact package for the high-end audio market. The result is not only a well voiced amp with loads of weighty power but also clear, transparent audio quality.
Allen & Heath’s unique ‘Constant Power’ system ensures that all available power is converted into useable speaker power so we can guarantee the full 500W RMS per side into 4 ohms OR 8 ohms.
