PA series mixers are designed to provide all the tools you need to run a regular stereo PA system in a straightforward ‘walk up and go’ format. You’ll quickly feel at home with these desks, but you’ll also find that we’ve included a number of those innovative touches that you only get from designers who have many years of ‘real world’ experience. If you care about quality you’ll also appreciate the build standards that the PA series conforms to, including the same individual vertical circuit boards, nutted pots and solid copper buss interconnection as our acclaimed ML series consoles. As for audio performance, PA series mixers have the wonderfully full, open, natural quality that you’d expect from a professional ALLEN&HEATH desk.

The PA20 has 16 mono plus 2 dual stereo channels, giving a channel count of 20 inputs, while the PA28 has 24 mono plus 2 dual stereo channels. Main features are a new padless preamp, internal FX unit, SPDIF output and parametric output EQ.

The mono channels feature an XLR input with individual +48V phantom power, and a TRS jack input. The TRS input feeds a new two-stage padless preamp which directs line sources to the second stage for improved matching and performance.

4 auxiliary sends are included, with 2 pre-fade sends for foldback, one post-fade for internal or external FX, and another post-fade for additional FX or special feeds. Mute and PFL switches with LEDs, peak metering and a full 100mm fader are also provided.

The 4 band semi-parametric EQ which proved to be such an important feature on the amplifier outputs of the PA-CP powered mixers is also available on the main outputs of PA20 and PA28. The EQ is a specially-designed 4-band type, with shelving LF and HF, a fixed LM band at 250Hz and a swept HM.

Also included in the mixers’ comprehensive feature set: built-in editable FX, 12-segment LED meters, XLR lamp socket and background music facility.
