appropriate for your local mains supply as
provided with the icon. This equipment must be
earthed (grounded). Do not remove the earth
connection from the power cord.
 Route the power cord so that it will not be walked
on, have heavy items placed on or against it or be
subject to heat, moisture or tension. If the power
cord is damaged or cut refer to your dealer for a
replacement. A damaged or modified power cord
is a potential fire and electrical shock hazard.
 To reduce the risk of fire or electric shock do not
expose the icon to rain or water or use it in damp

if it is to remain unused for a long period of time.
 Do not locate the icon in a place subject to
excessive heat or direct sunlight as this could be a
fire hazard. The ambient operating temperature
should not be less than 5°C (41°F) or greater than
35°C (95°F).
 Do not obstruct the ventilation slots or position
the icon where the air flow required for
ventilation is impeded. icon uses forced air
cooling with ventilation slots on the front, sides
and underside. Do not operate the icon on soft
materials such as a thick pile carpet or sofa which
may block the underside openings. If the icon is
to be operated in a rack unit or flightcase ensure
that it is constructed to allow correct ventilation.
 Do not subject the icon to excessive shock or
vibration. Ensure adequate protection when
moving, transporting or shipping the icon.
CAUTION
 Turn off the icon immediately if it is exposed to
moisture, liquid spilled on the panels, objects
fallen into the openings, the power cord become
damaged, if the equipment has been dropped or
become damaged, or if smoke, odour or noise is
noticed. Consult your dealer for repair.
 The icon is a heavy piece of equipment due to
the nature of the internal power supply and power
amplifier components. Always ensure you are
correctly positioned and grip securely when
lifting, moving or transporting the equipment.
Before operating the icon ensure that it is stable
and securely positioned. Failure to ensure this
may result in injury to yourself or damage to the
equipment.
 Follow the instructions printed in this guide for

 Avoid electromagnetic, radio frequency and
magnetic fields such as those generated by
televisions, computers, motors and lighting
equipment. If interference is encountered
relocate the affected equipment or cables.
 Avoid the use of chemicals, abrasives or solvents
in cleaning the icon. Use a soft brush and dry
lint-free cloth.
 Connect the icon as specified using the correct
cables and connectors for their intended purpose
only. Do not connect any source of AC or DC
power to the icon audio connectors.
 Set the output levels to minimum when
connecting external equipment or reconfiguring
the icon.
 Do not operate the equipment for a long period of
time at a high or uncomfortable volume level as
this may cause permanent hearing loss.

INTRODUCTION 1
Welcome to the new generation of live performance mixing !
The Allen & Heath icon SERIES combines the established principles of audio
mixing with state-of-the-art digital electronics and control technology to bring
you a revolutionary new set of live sound tools more powerful and yet easier to
use than traditional analogue mixers. The unique versatility makes icon well
suited to many small sound reinforcement applications including bands, duos,
soloists, cabaret, clubs, theatres, multi-function venues, schools, churches, PA
rental … and more.
This User Guide describes two models in the icon SERIES, the DP1000 and the
DL1000. The models are identical except that the DP1000 includes a built-in dual
power amplifier. The overview, installation and operation of these mixers is
described in the sections that follow. For further information on the basic
principles of audio system engineering please refer to the specialist publications
available from bookshops and audio equipment dealers. Further support is
available from your dealer and the Allen & Heath Internet web site.
To get started quickly please refer to Section 5 GETTING STARTED.
However, we recommend that you take the time to read the rest of this guide to
enjoy the full benefit of your icon mixer.
OVERVIEW
The icon is a 10 input 4 output digital audio mixer with performance memory system designed
for small high quality live sound applications. It provides a complete sound system in a single
portable package by including both mono and stereo input channels, built-in parametric and
graphic EQ, compressors, noise gates, dual effects processing, together with full mixing
facilities and a built-in power supply. Additional outputs are provided for recording, auxiliary
and slave amplifier feeds. The DP1000 is a known as a ‘powered’ mixer as it includes a built-
in power amplifier for direct connection to loudspeakers. The DL1000 is identical except that
it does not include the power amplifier. Instead it provides a pair of main outputs suitable for
driving an external amplifier system, or for use as a sub-mixer.
Unlike traditional analog mixers, the control settings can be stored and recalled from memory.
The stored memories can be sequenced for recall in the required order. This makes it very easy
to automate the performance or change between events without having to manually reset the
controls. The benefit to the musician or small band is that the settings appropriate to each song
can be recalled according to the set being played by simply pressing a pushbutton, footswitch
or MIDI. Additional memories store the settings appropriate to the venue being played.
Theatre shows can be automated by storing and recalling the settings for each scene according
to cue list. Control settings for regular events typical of multi-function venues, clubs, schools,
churches, conferences centres and so on can be set up and instantly recalled from memory.
Memories can be copied, named, archived and locked to prevent them being accidentally
overwritten. MIDI and RS232 ports are provided to allow data archiving and downloading of
future software upgrades. Version 2 software now includes the ability to control all the icon
performance parameters via MIDI.
The icon is easy to use with a simple uncluttered control layout that does not sacrifice the
instant access so important in live performance. The large illuminated LCD display and
custom soft touch backlit controls allow operation in both light and dark conditions and
provide a very graphical display of the selected functions without complex multi-level menus.

1 - 2 icon SERIES

CONFIGURATION
The icon provides 6 mono and 2 dual stereo channels. The 6 mono channels accept either a
microphone or a line level signal. The microphone inputs are balanced XLR with globally
switched +48V phantom powering. The line inputs are balanced 3-pole TRS (Tip Ring Sleeve)
phone jack and can accept balanced or unbalanced signals. The 2 stereo channels include an
XLR mic input so that the icon can be used as an 8 input microphone mixer if required. Each
has two stereo line inputs which combine to allow two sources to use the same channel
simultaneously, for example a keyboard and additional voice module, or a stereo guitar
processor and a CD player. One input is on a pair of TRS phone jacks, the other on RCA
phono pin jacks. The stereo signal can be switched for mono operation. A further two
dedicated stereo channels are included for the built-in effects processors FX1 and FX2. This
allows up to 14 inputs to be connected to the 8 channels of the icon with control of 18 signals
in the mix.
The icon provides four output mixes: the main LR stereo mix, FB foldback monitor mix and
the AUX output which can be configured pre or post channel fader. These mixes are available
on TRS jack outputs and can also be configured as required to the two amplifier outputs A and
B. The LR mix is summed to an additional mono output jack. The DP1000 has a built in dual
power amplifier with outputs on Speakon®connectors. The DL1000 has two balanced XLR
outputs to feed external amplifiers. The AB outputs can be configured as :
• A=L B=R Stereo mode = PA with separate left and right outputs
• A=FB B=M Split mode = mono PA and single foldback monitor
• A=Aux B=FB Monitor mode = external PA and 2 foldback monitors

DIGITAL MIXING
Mixing audio signals in the digital domain provides icon with its powerful processing tools,
programmability and sonic clarity well beyond the capability of traditional analog mixing.
However, no additional expertise or equipment is required for operation. The audio signals
enter and leave in standard analog format, and the usual familiar controls are presented.
The input sources are matched to the operating level of the mixer through high grade pre-
amps, then converted to digital signals using A/D (analog to digital) converters. In the digital
domain audio signals are represented as binary numbers which are mixed and processed by the
DSP (digital signal processor) by applying mathematical operations known as algorithms. No
matter how complex these algorithms they are always accurate and do not suffer the usual
noise, distortion and crosstalk problems associated with analog mixing. An algorithm is the
digital equivalent of an electronic circuit. The circuits in analog mixers can be complex, take
up considerable space and are not easily modified once built. Digital algorithms are stored as
data in computer memory and can be easily adapted in software. A built in computer reads the
changes you make to the controls and sends instructions to the DSP accordingly. The control
settings can be stored as digital data in memory for recall later. Once processed the signals are
converted back to analog audio using D/A (digital to analog) converters. The computer
operations are determined by a software program which is loaded in memory. The icon
includes an RS232 serial computer port which allows for future upgrades to this software as
well as the archiving of user data.
THE USER INTERFACE
The icon retains an easy-to-use control panel with familiar controls. Multi level menus are
avoided. Important performance controls such as channel gain, faders, mute switches,
amplifier levels and headphone monitoring are instantly accessible. Access to the auxiliary
mixes and signal processing such as EQ, dynamics and effects is by a single key press which
assigns the function of 10 rotary controls and associated LCD display. This is known as the
‘soft strip’ as its function is determined by the row of select keys beneath. For example, it can
become a channel EQ with simultaneous control of all four bands, or it can be used to set up
the foldback mix with all channel sends presented at the same time. A cursor keypad provides
menu control and additional editing functions including copy, paste, undo and reset.
The icon soft strip keeps the layout simple and logical with easily accessed controls. The keys
are shaped and grouped according to function and together with the LCD display are backlit
for operation in low lighting conditions. The display provides instant visual feedback of the
control settings, EQ response curve, setup menus and memory names using large text easily
read from the performance position.
The icon can be put into standby mode when leaving the mixer unattended or reconfiguring
equipment. Pressing the front panel standby switch disconnects the loudspeakers, mutes all
outputs and disables the controls.
MIXING THE AUDIO SIGNALS
The channel signals are mixed and routed to the outputs using the faders and level controls.
Signals can be panned between left and right in the main LR mix to create a stereo image.
The balance and level of the FB monitor and AUX mixes is independently controlled. Each
input and output has its own channel strip with 100mm fader, mute switch to turn the signal on
or off, PFL switch so that the signal can be independently monitored using headphones, and
peak indicator to warn if the signal level is too high. The fader always takes control of the
channel signal level and is not automated. However, a trim function is provided so that level
differences between songs or scenes can be stored in memory if required. With the faders set
at normal ‘0’ position, recalling the memories adjusts the levels as programmed. For example,
this can be useful when backing tracks have been recorded at different levels and would
otherwise require manual adjustment during performance.

EQUALISATION
The equaliser (EQ) is one of the most important signal processors in live sound mixing. It
allows the tonal response of the signal to be precisely adjusted to enhance selected frequencies,
for example to brighten up a dull guitar sound, or to deal with problems such as acoustic
feedback and instrument resonance. All input channels feature 4-band parametric EQ.
Parametric means that the parameters for each band can be separately controlled. Each has its
own variable gain control to boost or cut the frequencies selected using a sweep control. The
low frequency (LF) band has a shelving response and affects all frequencies below the selected
frequency. The high frequency (HF) band is shelving and affects all frequencies above the
selected frequency. The low mid (LM) and high mid (HM) bands have a bell shaped response
and affect frequencies either side of the selected frequency according to the width control. A
variable frequency high pass filter (HPF) is automatically selected by turning the LF gain to
minimum. This is useful in eliminating the annoying ‘popping’ sound produced when close
miking vocals. The effect of the EQ controls is displayed on the LCD as a large level versus
frequency graph.
The AB amplifier outputs each feature a 10-band graphic EQ for overall frequency adjustment,
for example to compensate for room acoustics or loudspeaker characteristics, or to tailor the
foldback monitor. These may be linked for stereo operation or used independently. The
extreme frequency bands are useful for filtering out very low and high frequencies to prevent
the amplifiers wasting energy on inaudible sounds.
An in/out switch is provided so that comparisons can be made between the original and the
adjusted signals. The EQ settings can be easily copied from one channel to another, copied
between memories, reset flat, or the recent changes can be undone.
DYNAMICS PROCESSING
The icon includes much of the signal processing usually found in the outboard equipment
rack. Each input channel features both a noise gate and a compressor. These can be used to
correct problems with the sources or used creatively for effects. The noise gate shuts off
signals below a preset level to eliminate background noise typical of old keyboards and guitar
effects boxes. Controls include threshold level, attack and decay. The compressor reduces the
dynamic range of the signal and is typically used to control vocal microphone levels. It can
also be used creatively, for example to tighten up a bass guitar sound. How much compression
you apply is determined by the drive control. This combines several parameters of the
compressor including threshold, ratio and makeup gain into one control making it very easy to
set up. Other controls include attack, release and hard/soft knee.
EFFECTS PROCESSING
The icon features two independent built-in stereo effects processors. FX1 provides a wide
range of echo and modulation effects including mono/stereo echo, chorus, flanger, tremolo and
vibrato as well as foot pedal volume control. FX2 provides different types of reverb and
echo+reverb multi-effects. FX1 is an ‘Insertion Effect’. Individual channel wet/dry controls set
how much signal is routed through the effects channel or direct to the mix. FX2 is a ‘System
Effect’ with the signal always routed direct to the mix (dry). The amount of effect (wet signal
such as reverb) is set using the individual channel send controls which add the effect to the
mix. FX2 can be fed to FX1, and FX1 can be fed to FX2, for example to add reverb to an
echo. The icon provides 40 presets per effect. Each has up to four parameters which can be
user adjusted to create precisely the effect required. Parameter changes are stored in the song
memories. Presets can be easily reset to the factory default. The effects can be muted using
footswitches or their levels controlled using foot pedals. A fader, mute switch and PFL switch
are provided for each effects channel.
icon SERIES 1 - 5

THE PERFORMANCE MEMORY SYSTEM
The icon is a programmable memory mixer. This lets you accurately recall previous settings
without having to manually reset every control. The memory system is structured specifically
for live performance. The memories also apply in theatre where scenes can be sequenced
according to a cue sheet, or in multi-function venues such as clubs, schools and houses of
worship where settings change according to event or user. Three types are provided:
• VENUE memories store the settings associated with how the mixer is set up for the
performance venue. This includes the amplifier configuration and graphic EQ settings.
• SONG memories store the settings which are likely to change between songs or scenes.
This includes the EQ, dynamics, effects, mutes and mix pan and level settings.
• SET memories store the sequence of song memories for recall during live performance
using panel or foot switches. A ‘set’ is the play list or order in which songs are to be
performed.
You can decide how you want to use the Song memories. A ‘safes’ system lets you choose
what parameters on which channels you want affected by the memories. You can, for example,
use the system to recall effects and EQ changes on your guitar channel only rather than
overwriting all your settings. This provides the system with huge flexibility.
There are 19 Venue, 127 Song and 9 Set user memories. A special song memory known as the
PAUSE patch toggles the mixer between the current settings and an alternative setting. This is
normally used for intermission chat between songs where it may be desirable for example to
reduce the level of effects and mute some of the channels. Alternatively it could be used to
toggle between two alternative settings for comparison, or used as a scratchpad memory. Panel
and footswitch control is provided. Changes made to the current and pause patches do not
need to be stored. These settings and the contents of the memories are saved when the mixer is
turned off.
Each user memory can be given an 8 digit name which is displayed in large characters during
performance. Selected memories can be locked for recall only so preventing accidental
overwriting. An 8 digit user name can be entered for mixer and data archive identification.
MIDI AND RS232
MIDI in and out sockets are provided so that memories can be recalled using MIDI program
change messages, individual channels can be muted using note on/off messages, individual
performance parameters can be accessed using controller messages, and the user memories can
be archived using system exclusive MIDI dump. The RS232 connector allows connection to
the serial port of a personal computer for data archiving and downloading of future software
releases. Refer to the Allen & Heath Internet web site for the latest information and software.
A rear panel selector switch determines whether the MIDI or RS232 interface is active.
THE DP1000 POWER AMPLIFIER
Two power amplifiers are included in the DP1000 powered mixer. These each produce a
maximum of 300 Watts into a minimum 4 ohms impedance. Outputs A and B benefit from the
10-band graphic EQ and are fed to the amplifier inputs. These can be configured in one of
three ways: stereo PA, mono PA with foldback monitor, or a larger system with two monitors
and an external PA amplifier. Speaker connections are the standard Speakon®type. The
amplifier and associated power supply are a linear design with metal cased bi-polar power
devices to ensure signal clarity and on the road reliability. Heat is dissipated and removed
from the unit using a 3-speed fan which sucks air in from the front of the unit, blows it over
the circuits and down a purpose designed extruded heatsink funnel to the exhaust vents in the
side. The fan blows briefly at full speed on power up to test and clear the system, then slows
to idle speed until a rise in temperature is detected. Loudspeaker protection is provided by
relays which disconnect the speakers if DC or excessive temperature is detected. These relays
also delay speaker turn on for a few seconds on power up to allow the amplifier circuits to
stabilise. A current limit circuit protects the amplifier from excessive loading or short circuits.

INSTALLATION
The icon can be used either free standing or installed in a rack. If it is to be frequently
transported we recommend that it is carried in a suitable flight case. Although very compact,
consideration must be given to the weight when installing or handling the product. The
DP1000 includes a power amplifier which necessitates the inclusion of heavy power
components. Consideration must also be given to the ventilation requirements of this model.
Details are given below. Dimension and weight details are provided on the following page.
To ensure your safety please read the IMPORTANT INSTRUCTIONS printed at
the beginning of this User Guide.

HANDLING AND MOVING THE CONSOLE
The icon is a heavy piece of equipment due to the nature of the internal power supply and
power amplifier components. Always ensure that you are correctly positioned and grip
securely when lifting, moving or transporting the equipment. Lift the console at the centre of
its side lips or under the base. Avoid contact with and therefore possible damage to the
controls. Before operating the icon ensure that it is stable and securely positioned. Failure to
ensure this may result in injury to yourself or damage to the equipment.
FREE-STANDING OPERATION
Position the console on a secure flat surface such as the floor or a table. Do not operate the
console on soft furnishings such as a sofa, or on thick pile carpet which may restrict air flow
around the chassis. Ensure that the cables are positioned where they will not be stressed or
stepped on.
Do not obstruct the ventilation
slots or position the icon where the
air flow required for ventilation is
impeded. Cold air is sucked in
through the slots at the front of the
console and warm air blown out
through the side ventilation slots.
RACK MOUNTING
The icon is designed to be mounted in a standard 19” equipment rack by fitting a pair optional
rack ears. This is available through your dealer. Fitting instructions are supplied with the kit.
The console requires an 8U front panel space with additional space for the connectors which
plug into the rear (top when rack mounted). Make sure the rack is strong enough to take the
weight and that the equipment is securely mounted. Ensure adequate ventilation around the
unit.
FLIGHTCASING
A flightcase is recommended if the console is to be frequently transported between venues.
There are many flightcase suppliers who can provide a case to satisfy your requirements.
Make sure the case provides adequate strength and protects the controls and exposed parts.
Do not operate the icon in the flightcase if the front and side ventilation slots are
obstructed. Failure to observe this may result in damage to the console.
Do not under any circumstances disassemble the console or attempt to drill
additional fixing holes. Side bracket fixing holes are provided under the side lips.

The DP1000 and the DL1000 front panel control layout is the same except for the labelling of
the A, Blevel controls and MODE select key. This is because the DP1000 includes a built-in
power amplifier, while the DL1000 provides balanced XLR outputs instead. The controls are
soft touch for user comfort, and the display and keys are backlit for viewing in dark conditions.
The ANALOG CONTROLS match the connected analog inputs and outputs to the console
before and after the digital signal processing. The STANDBY SWITCH turns off the outputs
and locks the controls when the console is replugged or left unattended. HEADPHONES may
be plugged in to check the individual input and output signals without affecting the mix. A
large DISPLAY provides information about the console status and settings according to the
row of controls immediately below. These controls are known as the SOFT STRIP as their
function is determined by which of the round SELECT KEYS is active. In this way the same
set of controls is used for many of the console functions such as setting up the EQ, dynamics,
effects and programming the memories. The CURSOR KEYS are used for memory scrolling,
menu and editing functions and to confirm changes to the settings. The AUTOMATION
CONTROLS are used for memory recall during live performance, and to isolate selected
channels from the automation. The PERFORMANCE CONTROLS provide instant access to
channel levels, muting and monitoring during live mixing.

GAIN Matches the sensitivity of the channel input to
the connected source. Use the headphones monitor to
check the signal quality and adjust the control until
the meters read an average 0dB with the loudest
peaks up to ‘+6’. If set too high the signal may clip
and produce a harsh distorted sound. If set too low
the signal to noise ratio is reduced and excessive
noise may be heard. Always turn back the gain if the
red channel peak indicator flashes.
MONO Press this switch to sum the stereo channel
left and right signals together to produce a mono
signal, or when using the channel with a mono source
such as a microphone. If the switch is not pressed
the mic signal will appear on the left channel only.
MIC +48V Press this switch when using
microphones which require phantom powering. This
puts +48V DC on all the XLR mic input sockets.
Note that you can connect non powered microphones
to powered sockets without damage as long as
balanced leads are used. The switch is recessed to
prevent accidental operation and should be operated
with a pointed object such as a pen.
To prevent damage to the microphones
always use balanced mic leads. Do not connect
unbalanced sources to powered inputs. Always
plug the microphones in with +48V turned off,
and only switch +48V on or off with all output
faders turned down. Failure to do this may result
in loud thumps and damage to external
equipment.
AB LEV These are the volume controls which set the
listening level of the amplifiers. Start with these set
to minimum and adjust the faders until the meters
read around 0dB for the average signal level. Raise
the level controls until the required sound level is
heard from the loudspeakers. When set correctly the
faders and meters may be operated within their
correct range. When set incorrectly distortion or
excessive background noise may result. The normal
position for loud program should be between 12 and
3 o’clock.
To avoid the possibility of unexpected high
sound volumes always set the AB level controls to
minimum when changing the amplifier
configuration.
☺Tip Take time to set the input and output levels
correctly. This will ensure that you get the best
performance from your system. The meters and
headphones monitoring system are provided to help
you set the levels accurately. If the levels are set too
high then distortion may result. This will be
indicated by the channel peak indicators flashing. If
the levels are set too low then excessive background
hiss and noise may be heard. This will be indicated
by very low meter reading

PFL key
The headphones monitoring system lets you listen to
any selected input or output signal using stereo
headphones. The signal is selected by pressing a
channel PFL switch. This is referred to as PFL (Pre-
Fade Listen) as the signal is monitored before the
fader. This means that the fader has no effect on the
monitored signal and can be turned down to allow
signal checking before raising the level in the mix.
Only one channel can be monitored at a time. The
signal is heard in mono or stereo depending on the
source. Each input, effect and output channel can be
monitored. The headphones are quiet when all PFL
switches are off. Raise the headphones level control
for comfortable listening level.
☺Tip We recommend that robust good quality
enclosed ear stereo headphones of 30 to 600 ohms
impedance are used to ensure signal clarity and
continued reliability.
