pots and solid copper buss interconnection as our acclaimed ML series consoles. As for audio performance, PA20 mixers have the wonderfully full, open, natural quality that you’d expect from a professional ALLEN&HEATH desk. 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 equaliser with swept frequency on each band provides more precise optimisation of the speaker system and control of feedback than the typical fixed frequency graphic type EQ found on similar consoles.

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. 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 labelled and colour coded, and there are generous 100mm fader masters with a LED mute button, identical to the channel controls.
