Product Description


Allen & Heath PA20-CP

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.

Mono Inputs
16 mono channels with Mic [XLR] & Line [TRS] inputs. Line input overrides the XLR input. Individual +48V phantom power switches are provided. New padless two-stage preamp with smooth gain law. Line input goes to second stage for better matching and performance. Switched 100Hz high pass filter. Insert point. 4 band EQ. 4 aux mixes. Mute with LED. PFL button with LED [functions as peak indicator]. 100mm fader.

Dual Stereo Channels
Two stereo channels with two unbalanced stereo inputs on each. One is RCA one is TRS jack. Independent gain controls provide source mixing in the channel strip. The top inputs [RCA] can be switched direct to L&R instead of the channel strip providing extra returns. Two band shelving EQ. 4 aux mixes. Stereo balance, mute with LED, PFL with LED, and 100mm fader as mono channels.

4 Auxiliary Sends
From all channels: 2 pre-fade for foldback mixes - these have 100mm fader masters, mute switch with LED, AFL with LED, and TRS outputs [can be routed internally to output section]. 1 post-fade aux mix for FX - this feeds the internal FX and has a TRS jack output for external FX. 1 post-fade aux mix to TRS jack output is provided for external FX or special feeds.

Mix Outputs
Main stereo mix output has 100mm fader control & mute with LED. TRS jack outputs. Mono sum output with level control with switch for subwoofer mode to TRS jack. Record output [RCA] analogue + SPDIF switchable pre/post fader. Twin 12 segment LED bar meter shows program [or PFL /AFL]. Insert points on TRS jack for external processing. Output EQ and routing to internal amplifiers / external systems is provided.

Output EQ
4 band semi-parametric EQ is provided in the output section, this affects the TRS slave outputs, and the internal constant power amplifiers. This offers more control than graphic equalisers for precise management of speakers, especially foldback / monitors. Source selector allows output EQ section to be used on Left / right, L&R sum / foldback1, or foldback1 / foldback2.
