Precision control over an incredible number of parameters.
The Allen & Heath PA 20 Mixer gives you the tools you need to run a stereo PA system in a straightforward
plug-and-play format. You'll quickly feel at home with a number of innovative touches based on many years of real-world experience.
High-quality construction includes the same individual vertical circuit boards, nutted pots, and solid copper bus connections
as the acclaimed ML series consoles. Experience the mixing console's full, open, natural sound quality that has made Allen
& Heath a respected name around the world.
16 mono channels with mic (XLR) and line (TRS) inputs (line input overrides
the XLR input), individual +48V phantom power switches, and new padless 2-stage preamp with smooth gain law provide pristing
sound quality. 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), plus 100mm fader on every
channel.
Shelving LF (60Hz), and HF (12kHz) with fixed LM (250Hz), and swept HM (300Hz - 6kHz). The fixed 250Hz control
has been carefully selected to provide reduction of muddy sounds and enhance warmth.
The PA 20 mixing console's 2 stereo
channels with 2 unbalanced stereo inputs on each-one RCA and one 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.
Each stereo channel features 2-band shelving EQ, 4 aux mixes, stereo balance, mute with LED, PFL with LED, and 100mm fader
as mono channels.
Auxiliary sends from all channels include 2 pre-fade for foldback mixes - these have 100mm fader
masters, mute switch with LED, AFL with LED, and TRS outputs (which can be routed internally to output section). One post-fade
aux mix for effects which feeds the internal effects and has a TRS jack output for external effects. One post-fade aux mix
to a TRS jack output is provided for external effects or special feeds.
Main stereo mix output has 100mm fader control
and mute with LED plus TRS jack outputs, mono sum output with level control and switch for subwoofer mode to TRS jack. Record
output (RCA) analog and SPDIF switchable pre/post fader, plus twin 12-segment LED bar meters that show program (or PFL/AFL).
Insert points on TRS jack for external processing as well as output EQ and routing to internal amplifiers/external systems
are provided.
The Allen & Heath PA 20 Mixer has a 4-band semi-parametric EQ that enhances the output section. This
affects the TRS slave outputs and the internal constant power amplifiers, offering more control than graphic equalizers for
precise management of speakers, especially foldback/monitors. Source selector allows output EQ section to be used on left/
right, L&R sum/foldback 1, or foldback1/foldback 2.
16-program digital effects processor provides reverbs, delays,
chorus, and others, including combinations. This FX module takes its feed from the post-fade FX aux on the mono and stereo
channels. The output of the FX module is controlled by a 100mm fader with mute and PFL and is routed to the stereo mix and
FB1&2 with post fade level controls. 2 TRS inputs with level control provide a way of combining external effects with the
internal unit. The audio mixer's internal effects can be switched off to use external effects only if preferred. A footswitch
TRS jack is provided to mute the effects channel. Editing of effects can be done via MIDI using the software editor available
free from the resource CD or the Allen & Heath website.
Background music (BGM) mode plays 2 track input into the main
mix post fader, allowing the user to pull down the fader (while patching, taking a break, or during walk-in) and leave music
playing through the amplifiers/speakers. 2 track input (RCA) with level control to L&R feeds the headphone monitor selector
(checking recording) while twin, 3-color 12-segment LED meters display active monitor source. Large LED indicates PFL/AFL
active signal overrides L&R/2TRK monitor source selection. Standby switch uses relays to disconnect the speakers. 2 track
output (RCA) analog + S/PDIF allows direct-to-digital recording. Switchable pre/post master L&R fader. Mono sum out with level
(TRS) mode switch to provide sub feed with 100Hz low pass filter. Phones out (TRS) with level.
