PA User Guide
Overview
PA Series consoles provide the tools you need to run a small PA system in an easy ‘walk up and go’
format. You simply plug in your microphone and line sources and connect to your amplifiers or
powered speakers. All the control and processing you need is built into the console.

This guide describes the ‘unpowered’ PA models available in three frame sizes PA-12, PA-20, and
PA-28. These have 8, 16 and 24 mono mic/line plus 2 dual stereo channels respectively. ‘Powered’
PA12-CP and PA20-CP models are available with built-in 2x500W power amplifiers. These are
described separately in user guide AP4956. The unpowered PA provides a more compact and
lightweight choice for systems using external amplifiers or powered speakers.

PA Series consoles are portable and include protective side trims and front carry handles. The PA12
can be mounted in a standard 19” rack or plinth by removing its trims and fitting the optional rack ears
provided.

We recognise the importance of accurate equalisation both for creative sound processing and for
dealing with problems such as feedback and room resonance. We have chosen to include versatile
four band semi-parametric rather than traditional graphic EQ on the main A and B outputs. This
provides far greater accuracy and therefore less colouration of the sound. The AB outputs can be
configured in several different ways according to your PA requirements. For example, you may run a
stereo house system without monitors, or a mono system with additional musicians monitor speaker,
or you may use both for two independent monitors. The additional mono output can be used, for
example, to feed a sub bass amplifier/speaker system or another listening zone.

The channel strip features a powerful four band EQ with two mids, one with swept frequency control.
Four bands allow more accurate tonal control than the common two or three band channel EQ found
on similar consoles. The built-in digital effects unit provides 16 useful presets including reverbs,
delays, echo and other types.

Years of designing mixers and listening to our customers has resulted in a control surface that presents
a well thought out set of functions including many innovative touches that make the job of mixing a
simple pleasure. Notable features include individual phantom power, space saving dual stereo inputs,
BGM (background music) mode, built-in digital effects processor, lamp connector, selectable sub filter,
recording source selector and even an SPDIF digital output.

The name Allen & Heath is well regarded in the professional audio world. The standards applied to our
top end consoles also apply to the PA Series. High grade circuits and components, 100mm faders,
individual vertical circuit cards with sealed potentiometers nutted to the panel, solid grounding with
internal solid copper buss and steel chassis construction are just a few of the qualities that put this
console into a class of its own. Our objective was to provide a truly professional solution for small
system mixing. We hope you enjoy using your PA Series console.
