Allen and Heath PA20CP Powered Mixer; Where innovation and power meet diminutive design. The years of experience Allen and Heath have gained in designing large format touring mixers has enabled them to see where mandatory innovation is needed to incorporate these designs to make the same use of smaller sized PA mixers. Allen and Heath have met this challenge and now offer the same superior build and sound quality as their feature-packed pro audio design to an even wider audience. Now every aspiring act or audio team can benefit from a truly professional system.

Walk up and go is the way the PA20CP mixer has been described, all the controls you expect are placed in logical positions so you won't have to think twice about where your fingers need to be, even when under the pressure of any performance. Boasting a versatile 4 band EQ on both the inputs and outputs and clever output routing are unique features and ensure you get the best out of the system. Other features like the individual phantom power switches and SPDIF recording output add the professional finishing touches you've been searching for.

Add sparkling clarity to your performance with the superior sound quality of a PA Series mixer.

High Performance Preamp
The mic preamp is probably the most important stage in the console's signal path and its performance is often the measure of the quality of the console. The PA Series uses a high grade dualstage design, developed from our top-end range of ML and GL consoles. This ensures optimum matching and very low noise when connecting mic or line sources.

Parametric Output EQ
A 4 band equalizer with swept frequency on each band provides more precise optimization of the speaker system and control of feedback than the typical fixed frequency graphic type EQ found on similar consoles. Download the free EQ Visualizer program from the Allen & Heath website to learn more about using this powerful tool.

Filter
Each mono input channel is equipped with a 100Hz high-pass filter, an invaluable tool for cleaning up the mix. The majority of live sound sources have very little content below 100Hz, and modern microphones have wide frequency response and can pick up bleed from nearby low frequency sources such as bass and kick drums. The filter can be used: on vocal channels to reduce mic handling noise and close proximity popping; on drum overhead mics to reduce kick and bass pick up; on higher frequency instruments such as flute and acoustic guitar; and on stage mics to reduce foot noise.

Recording Outputs
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. An analogue recording output is also available.

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.

Lamp socket
A 4 pin lamp connector is provided on the rear of the control surface.

Easy-to-Mix Controls
The control surface is laid out in an uncomplicated format and the operator can easily see all connections for patching. Pre-fade sends (FB) and post-fade sends (FX) are clearly labeled and color coded, and there are generous 100mm fader masters with a LED mute button, identical to the channel controls. There is a selection of 16 editable digital FX to complete the professional design.

Stereos
2 dual stereo channels with RCA and TRS connectors and independent gain controls are included for FX returns and stereo sources, such as CD players and backing tracks. The RCA inputs can feed straight to LR, so providing extra returns. The stereo channels are furnished with 2 band EQ, and can be routed to all 4 auxiliary sends.

Powered Option
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.

A+B Output Channels
The main outputs derive their source from a selectable combination of LR (stereo), L+R (mono), FB1 and FB2, and provide master level trim, meters, slave outputs, patch point for external processors, and the very precise 4 band semi-parametric equalizers. This is extremely flexible and means that the PA can be operated in many different ways. For example, the user may want to run a stereo house system with separate left and right speakers and no monitors, or a mono system with a foldback monitor. Alternatively, you may patch into a bigger house system and use the built-in amplifier to provide a pair of equalized stage monitors. The PA Series takes the concept of a PA in a box a versatile step further. read less
