INTRODUCTION
Thank you for choosing a DXi series amplifier for your application. Please spend a little time reading through this manual, so that you obtain the best possible performance from the unit and become familiar with its operating requirements. All DAS Audio Group products are carefully designed and engineered for cutting-edge performance and world-class reliability. If you would like further information about this or any other DAS Audio product, please contact us. We wish you many years of service from this amplifier and look forward to hearing from you in the near future. The DXi amplifier series has been designed to combine incredible audio power and performance with ultra-flexible connectivity for both remote control and audio. Exemplary audio processing is assured through the use of a DSP platform, and power amplifier capabilities are taken care of with high efficiency output stages and a generous power supply. All units named with an “i” include a DSP in the amplifier. DX-100I and DX-80I include a 4 in 8 out DSP platform. Accepting analogue, AES3 digital and optional Dante networked audio, the DXi amplifiers can connect to any source and make it available over the network, as well as processing four additional channels with local analogue outputs to connect to DX amplifiers. These auxiliary processed outputs can also be fed onto the network, and used by DX amplifiers that have Dante cards fitted, or by any other Dante enabled device. Connectivity for remote control is covered by USB, Ethernet and RS485, with relay of either USB or Ethernet control via RS485 to work with legacy products. Configuration of the amplifier's processing is through the industry standard DASnet application, with tuning and monitoring of a network of DXi amplifiers. With a range of power levels available in the DX Series, the amplifiers can be networked to a single DXi model, creating a powerful, efficient system that's easy to expand and adapt for use in live, install and everything in between.
INSTALLATION: ELECTRICAL CONSIDERATIONS
The amplifier has been manufactured to comply with your local power supply requirements, but before connecting the unit to the supply, ensure that the voltage (printed on the rear panel) is correct. The amplifier is fitted with either a 100/120V or 220/240V tapped transformer according to customer requirements. Make sure power outlets conform to the power requirements listed on the back of the unit. Damage caused by connecting to improper AC voltage is not covered by the warranty.
Safety Warning
Apparatus with CLASS I construction shall be connected to a MAINS socket outlet with a protective earthing connection. Where a MAINS plug or appliance coupler is used as the disconnect device, it should remain readily operable. Where the amplifier is mounted in a rack and permanently connected to the mains, then the rack should be installed with a readily accessible connector or an ALL POLE circuit breaker with 3mm breaking distances. This unit is fitted with a 3-wire power connector. For safety reasons, THE EARTH LEAD SHOULD NOT BE DISCONNECTED IN ANY CIRCUMSTANCE. If ground loops are encountered consult the section on Line Inputs and Outputs on page 11. WHERE A FIXED MAINS LEAD IS FITTED, THE WIRING COLOURS ARE:
230V AREAS: 120V AREAS:
EARTH = GREEN AND YELLOW GREEN NEUTRAL = BLUE WHITE LIVE = BROWN BLACK TO PREVENT THE LIKELIHOOD OF SHOCK OR FIRE HAZARD, DO NOT EXPOSE THE UNIT TO RAIN OR MOISTURE. DO NOT PLACE OBJECTS CONTAINING LIQUID ON TOP OF THE APPARATUS. TO AVOID ELECTRICAL SHOCK DO NOT REMOVE COVERS. REFER ALL SERVICING TO QUALIFIED PERSONNEL. DO NOT USE THE UNIT OF THE ELECTRICAL POWER CORD IS FRAYED OR BROKEN. The power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs and the point where they exit from the appliance. ALWAYS OPERATE THE UNIT WITH THE AC GROUND WIRE CONNECTED TO THE ELECTRICAL SYSTEM GROUND. Precautions should be taken so that the means of grounding of a piece of equipment is not defeated. DO NOT REMOVE THE LID. Removing the lid will expose you to potentially dangerous voltages. There are no user serviceable parts inside. ESD strikes to the unit's front panel that are in excess of 4000 volts may cause disturbance to the status LEDs on the unit. This will not affect audio performance and will be corrected on the next power up cycle.

INTRODUCTION (cont'd)
INSTALLATION: MECHANICAL CONSIDERATIONS
To ensure that this equipment performs to specification, it should be mounted in a suitable rack or enclosure as described below. Like all high power amplifiers, it should be kept away from other equipment which is sensitive to magnetic fields. Also, this amplifier may suffer a substantial reduction in performance if it is subjected to, or mounted close to equipment which radiates high RF fields. Warning: To prevent injury, this apparatus must be securely attached to the rack in accordance with the installation instructions. When mounting the amplifier in a rack or enclosure: Be aware that ... THE FRONT PANEL IS NOT CAPABLE OF SUPPORTING THE UNIT ON ITS OWN. Make sure that the rear of the unit is adequately supported. The brackets which are supplied fit standard 19 inch (483mm) rack mounting systems. ENSURE THERE IS ADEQUATE VENTILATION. The cooling fans suck cool air in through the front and blow hot air out at the rear of the unit through the ventilating grills. The front and rear of the amplifier should have free exposure to the air (i.e. in a rack leave the front & rear doors off), with 2cm air gap at the sides. IF AIR IS NOT ALLOWED TO ESCAPE FROM THE REAR, OVER-HEATING WILL OCCUR. Take care when mounting other equipment in the same rack. Make sure that the rack unit has a separate earth connection (technical earth). Please also see the notes regarding maintenance on page 10.
RF EMISSIONS
The high frequency resonant converters in the DXi series amplifiers have been designed to have very low radio frequency (RF) emissions; however even these low level emissions can cause interference with other equipment. In order for this to be minimised, the amplifier should be mounted in a metal rack enclosure, which should have a separate (technical) Earth. Alternatively a separate earth should be attached to the amplifier at the rear rack mounting bracket.
DYNAMIC AMPLIFIER PERFORMANCE MEASUREMENTS
The DXi series is the very latest example of a 'dynamic amplifier'. This new 'breed' of power amplifiers provide very high peak power levels in a much smaller, and lighter, package than previously possible with conventional amplifiers. They are designed specifically for today's high power audio installations, which use multiple speakers with electronic crossovers or speaker controllers. These systems can handle very high transient signals that far exceed their RMS power rating. The DXi series amplifiers have been designed to match this requirement and can deliver huge levels of power for short durations. In order to protect themselves and the loudspeakers that they are driving, continuous signals such as sine waves, are automatically detected and reduced (ramped down) to a safe level. When trying to measure the power output however, continuous signals will give totally incorrect results. A dynamic signal, such as a tone burst, should be used and the levels measured by monitoring the waveform on an oscilloscope. The power envelope can then be accurately measured. Our power output figures are measured using signals with known Crest Factors and are quoted at the rear of this manual on page 43 and on our website. Please refer to the technical area of our website for further information.
INITIAL SET-UP AND SWITCHING ON
Please read all documentation before operating your equipment and retain all documentation for future reference. Do not spill water or other liquids into or on the unit and do not operate the unit while standing in liquid. Do not block fan intake or rear ventilation outlets or operate the unit in an environment that could impede the free flow of air around the unit. If the unit is used in an extremely dusty or smoky environment, it should be cleaned of any collected debris at regular intervals. Please also see the notes regarding maintenance on page 10. It is important that the power output of your amplifier is matched to the power handling capacity of your loudspeaker. If not, damage to the loudspeaker could occur.
Switching On… At 'switch-on' the protection circuit will initially activate whilst the circuits stabilise, indicated by the red A/P LED illuminating, in addition to various other LEDs. After a few seconds the red A/P LED will extinguish indicating a satisfactory working condition. Other LEDs may remain illuminated depending upon rear panel switch settings and input connections. If the A/P LED does not extinguish after 5 seconds the unit may be faulty or some external connections may be incorrect or inappropriate. If this occurs you should power down the unit and remove all external connections (except for the mains power supply) and repeat the power up sequence. If the problem persists please contact us.

Note: The front panel is common for all models.
1: USB Type “B”: Connect to a computer for remote control – a driver will be required. Please see the section on remote control starting on page 36.
2: MUTE keys: This will mute the respective input or output channel according to the current setting of the bank control selection (#14).
3: 2 x 24 LCD: By default this will display preset names and is used to show all parameter information. The LCD contrast and backlight brightness can be adjusted in the System Sub-Menu - see page 32 for details. If the LCD backlight is flashing, it is being remotely identified by software.
4: PROTECTION LED: If a condition exists, either internally or externally, that could cause damage to either the amplifier or the speakers, the protection circuit will disengage the outputs and this LED will illuminate/flash. Typical conditions that could cause the protection to be triggered include very high frequency or subsonic input signals, DC in the inputs, short-circuited outputs, or internal high temperatures. The protection circuit can affect all channels or a 'channel pair' depending on the type of fault. This is indicated by the combination of Protection LED illuminating and a corresponding message on the LCD. In this way, it is possible for two channels (a channel pair) to remain functioning even though a fault has caused the other channel pair to mute. A channel pair would be 1+2 or 3+4. Temperature related faults will reset automatically if the unit has cooled sufficiently. Output short circuits will require manual reset after clearing the fault (switching off at the mains switch and then on again after a few seconds). Short circuits on either channel of a channel pair will only affect that channel pair.
5: BRIDGE pair LEDs: The channel pair LED will illuminate if these channels have been switched into bridged (mono) mode. See page 11 for details of how to connect your speaker to a bridged channel pair, and page 12 for how to enable bridge mode.
6: Power Switch: This double pole switch turns the amplifier fully off and isolates it from the mains supply.
7: STBY LED: The DXi amplifiers can be powered down leaving just the DSP active. Apart from the obvious power savings to be made, there may be circumstances when only the DSP is required, such as utilizing it for braking analogue audio channels onto a Dante network. This LED illuminates when the power amplifier sections are turned OFF. HINT: The amplifier can be brought out of standby by holding ENTER and QUIT at power-up.
8: REMOTE LED: This will flash when the unit is being addressed under remote control.

9: DIGITAL IN LED: This illuminates if either AES input is switched in (replacing the respective analogue input channel) and will flash if there is a loss of lock on either input. Note that this does not mean AES is actually routed to the amplifier's DSP, only that a rear panel socket is set to receive an AES stereo signal.
10: NETWORK AUDIO LED: This will illuminate when an audio network connection is correctly made to the amplifier. Note that this does not mean that any network audio channels are actually routed to the amplifier's DSP, only that the connection is available.
11/12: Rotary encoder and navigation keys: MENU is always the way under the bonnet of the amplifier, and then BACK and NEXT to choose the Sub-Menu and ENTER to select the choice. These controls are also used when editing DSP audio parameters, accessed via the EDIT keys.
13: Signal meters: Depending on the current bank selected (#14), these will be showing input levels pre­DSP, output levels for the power amp channels, or output levels of the auxiliary channels.
14: EDIT keys: First press on an EDIT key will show the gain for the selected channel within its respective BANK. Second press will display the last edited parameter - see pages 17 to 18 for more info on full real­time editing of input and output parameters.
15: BANK Select key and LEDs: This key will cycle through three banks: inputs A-D, power amp outputs 1-4 or auxiliary outputs 5-8, for both meter displays, mute functions and during editing. Bank select will default to showing power amp outputs on meters and mutes after 20 seconds of inactivity.

Group, S.L. The rear panel is common for all models.
1: Fan outlet: The variable speed fans suck air in through the front vents and out through the back of the amplifier. Please see maintenance for recommendations on how to clean this and the front foam sections.
2: Channel A output Speakon socket: Normal output is on pins 1+ hot, 1- cold. Channel B's output is also wired to this socket to enable a single NL4 to provide both channels and to facilitate easier wiring in bridged mode. Channel B is wired pins 2+ hot, 2- cold. Similarly channel C's output Speakon socket carries Channel D's output. Check the table on the rear panel for details.
3: Input XLR sockets: Connect signal inputs to these sockets, wired pin 2 hot, 3 cold, 1 ground. For sensitivity and impedance of these inputs, please see the specifications on page 43. Inputs C & D may also be switched to AES digital inputs, each carrying a stereo AES stream – channels A&B on socket C, channels C & D on socket D. This arrangement allows an analogue stereo source to remain connected to sockets A & B for fallback purposes. To select AES inputs please see the section on page 24.
4: Auxiliary output XLR sockets: These carry the four additional channels of separate DSP processing – they are NOT just link outputs or a copy of the power amplifier channel's processed audio – they are fully independent.
5: Audio network connections: Four additional inputs are available via the Dante network card included. This will also add four network audio outputs, which can be chosen (in banks of four) from a variety of processing points within the amplifier's DSP structure. For more on this feature see the block diagram on page 13 and set-up information from page 27.
6: Ethernet control port: Your amplifier may be remotely controlled by connecting it to a computer via this standard Ethernet port connection. Please see the section starting on page 35 for how to use this feature. HINT: You can quickly check the amplifier's IP address by pressing ENTER + NEXT.
7: GPIO Port: Your amplifier has a pair of general purpose logic level input and outputs that can be configured to recall memories, put the amplifier in standby, mute and control levels, and also provide feedback about status. Please see the section on page 36 for more details.
8: RS485 Port: Your amplifier may also be controlled via an RS485 connection, and this port may also be used to relay control data from the Ethernet port or the front panel USB port to connect to further devices. Please see the remote control section on page 36 for more information.
MAINTENANCE
These maintenance instructions are for use by qualified personnel only. Before any routine maintenance, please ensure that your amplifier is disconnected from the mains supply! The filter behind the air intake apertures on the front of your amplifier should be cleaned or replaced periodically, e.g. 12-24 months. (Filters in amplifiers located in more 'dirty' atmospheres may require more frequent maintenance). The filter should be 'dry' cleaned, using a vacuum cleaner preferably. Running the unit without a filter is not recommended unless it is within a 'clean room'. Replacement filter material is available. If the fan vents on the rear of the amplifier develop a build-up of dust/debris on the finger guards, they can be cleaned with a dry paintbrush and a vacuum cleaner. The casework of the amplifier may be cleaned with a lightly dampened cloth – do not use any solvents as they will damage the paint finish and could remove printing. If you have any doubts about carrying out maintenance, please refer to a service engineer or contact your local dealer.

LINE INPUTS AND OUTPUTS
The inputs are made via 3-pin XLR connectors, which are electronically balanced and should be connected via a high grade twin core screened cable, as follows:
Pin 1: Screen (see note below) Pin 2: Hot (signal +) Pin 3: Cold (signal -)
The amplifier is designed to operate with fully balanced equipment and ground loops or loss of performance may be experienced if connected to unbalanced sources. If it is unavoidable however, the following wiring should be used. The cable should still be twin core plus screen.
Pin 1: Screen - connected to the chassis of the unbalanced equipment - or left disconnected at the unbalanced end. Pin 2: Hot (signal +) Pin 3: Cold (ground 0V)
NOTE: This amplifier is wired to the latest industry recommendations. Pin 1 is connected directly to the chassis/mains earth. If ground loops (mains hum) are encountered remove the screen connection from the other end of the cable and leave it open circuit. If problems persist, consult your dealer/supplier. DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS INSIDE THE AMPLIFIER.
For bridged operation input should be made to channel A (or C) only and the channels set for bridged mode for the appropriate pair of channels.
Outputs are also made via 3-pin XLR connectors wired as follows:
Pin 1: Screen (see note above) Pin 2: Hot (signal +) Pin 3: Cold (signal -)
Note that the rear panel outputs are electronically balanced and so are not galvanically (electrically) isolated. Front panel outputs are transformer balanced and so are isolated.
SPEAKER OUTPUTS
The speaker outputs are via Neutrik Speakon connectors. 2 pole (NL2FC) or 4 pole (NL4FC) connectors can be used.
Pin 1+: Hot Pin 1-: Cold
Additionally, Channel 1 Speakon connector carries Channel 2 output on Pins +2 & -2 to allow easy bi­amping or bridged operation using a single NL4 connector. Similarly, Channel 3's Speakon connector also carries Channel 4 output.

REAR PANEL (cont'd)
For bi-amped operation, connect as above.
There must be no shared connections between channels.
Negative output terminals must not be joined together as they are not both at ground potential. Connecting them together will damage the amplifier and void the warranty!
As the currents involved are very high, and to ensure best performance, the speaker cables should be kept as short as possible and conform to the following minimum requirements:
DX-80I, 14A into 4 Ohm speaker loads DX-100I, 20A into 4 Ohm speaker loads
When operating the amplifier into loads of less than 4 Ohms, be aware that the current capacity of the speaker cables will need to be increased above the values quoted here.
Do not connect the inputs/outputs to any other voltage source such as a battery, mains source or power supply, regardless of whether the amplifier is turned on or off.
Do not run the output of any amplifier channel back into another channel's input and do not parallel or series-connect an amplifier output with any other amplifier output.
BRIDGED (MONO) OPERATION
Pairs of channels may be independently bridged – channel pair 1+2, and/or channel pair 3+4.
The method is the same for both channel pairs:
Select the required bridged mode through the front panel MENU system (see page 29 for more information).
Use Channel 1 or 3's Output Speakon connector and connect as follows:
Pin 2+: Hot Pin 1-: Cold
When operating in bridged mode, the minimum impedances are doubled.
The minimum load in bridged mode is 4 ohms.

Source Choices and Selection
Your amplifier can source audio from analogue, AES digital, or network locations (DANTE).
Analogue and AES digital audio are standard, and arranged so that AES digital audio can be chosen in pairs of channels to replace either analogue inputs A&B together or analogue inputs C&D together, or all four channels.
Physical input of AES for channels A&B is swapped to the input XLR for channel C and the AES input for channels C&D is on the XLR socket for channel D.
In this way, a pair of analogue inputs can remain connected to channels A&B and a digital stream of the same audio can be connected to input C, with fallback from one to the other possible without repatching.
With the DANTE card, four additional digital sources will be available.
In total, 8 sources can be made available at any one time – four analogue and four digital. This affects the choices that can be made for routing to the inputs of the DSP channels.
Analogue A and B is available at all times; If AES A&B is selected, Analogue C cannot be used (shares XLR C); If AES C&D is selected, Analogue D cannot be used (shares XLR D); If AES A&B is chosen, Dante A&B cannot be used (shares SRC One); If AES C&D is chosen, Dante C&D cannot be used (shares SRC Two);
Source selection is therefore affected by the selection of AES inputs, which then controls the choice of input source selections on offer to any input processing channel.
Please see page 23 for further info on using the AES and Input source selection menu options.
Input Processing Channels
Your amplifier has four input channels of processing that can be fed from a variety of sources.
These four channels in turn, feed a mix matrix for routing to the power amplifier processing channels and the auxiliary output processing channels.
Each input processing channel consists of the following sections:
Input gain control Input delay time Input parametric EQ bands 1 through 9
The dynamic EQ sections will be added in a future firmware update. For more information on adjusting input processing parameters, please see the section beginning on page 17.

Mix Matrix Section
The mix matrix allows four independent mixes to be set up for the power amplifier channels and the auxiliary output channels.
These can be either “Boolean” in design (so just A+B+C etc.) or a full mix matrix mode can be used to allow four continuously variable “sends” from the four input processing channels to be combined.
There are also a variety of templates to act as starting points for crossover duties, where useful crossover (high and low pass) frequencies are automatically assigned to groups of outputs, dependant on the format used. For more information on adjusting the mix matrix, please see the output editing section on page 22. Note that the mix matrix will only be available if it has been selected as part of the output/auxiliary configurations – see page 27 to change this.
Power Amplifier and Auxiliary Output Processing Channels
There are eight identical channels of output processing in your amplifier: four dedicated to the power amplifier channels, and a further four that are connected to the auxiliary XLR outputs on the amplifier, providing analogue feeds to other equipment.
Each output processing channel consists of the following sections:
Output delay time High and low pass crossover filters (up to 48dB/Oct.) Output parametric EQ bands 1 through 9 Output gain control Program (RMS) limiter Peak limiter
FIR filtering capabilities will be added in a future firmware update. For more information on adjusting output processing parameters, please see the section beginning on page 18.

DSP LAYOUT, CONFIGURATIONS AND ROUTING (cont'd)
Independent Network Audio Outputs
All DXi models have a network audio card fitted (Dante), this means being able to route four channels of audio from the network and, as well, being able to route four channels of audio back onto the network.
This feature is primarily intended for use with the DX series models, which may also be fitted with a network audio interface (optional), allowing them to utilise the additional processing channels in your DXi models via connection with a single Ethernet cable.
Working like this, the network audio outputs would be routed directly from end of the auxiliary output processing, so that they are just a copy of the signals available at the Aux XLR outputs 1-4 (choice #1 in the above diagram).
However, there are other circumstances where it might be more useful to route these outputs from elsewhere within the DSP processing. For example, if the network outputs are being used to also “break­in” analogue or AES channels, for use with other amplifiers, it might be more applicable to route the audio from the outputs of input processing channels (choice #5).
If it's required for the network outputs to break in channels that are not being used by the local processing, this can also be achieved by using the outputs of the mix matrix which feed the auxiliary output processing (choice #3).
Alternately, the mixes being used by the power amp processing can be selected (choice #4) and finally, the pre-mute final output of the auxiliary channels' processing may be selected (choice 2) to prevent muting the local aux outputs from muting the network feeds.
Note that these routing selections work on a “x4” basis – all four network output feeds are
selected from one of the above choices as a group – they cannot be individually assigned to different points.
For more information on selecting the network audio output routing, please see the section on page
26.

DIRECTLY EDITING AUDIO PARAMETERS
Overview
Editing all audio parameters is available from the front panel of your amplifier using a combination of the select BANK key, reassignable EDIT keys, and the BACK/NEXT/ENTER navigation controls.
First, make sure the correct bank of channels is selected – either inputs A-D, amplifier outputs 1-4 or auxiliary outputs 5-8 by pressing the BANK key.
Next, press the EDIT key that corresponds to the channel to be adjusted. The EDIT key will illuminate, and the gain will always be displayed as the first parameter.
To choose another parameter, use BACK and NEXT to scroll through the available choices.
If there are multiple parameters grouped on a single screen (such as parametric EQ frequency, 'Q' and gain) move between these using the ENTER key.

Press
ENTER
Finally, use the rotary encoder to adjust the value of the parameter.
You can swap bank at any time by pressing the BANK key, and to quickly access the same parameter on another channel (within a bank) double press on the required channel's EDIT key. If the same parameter doesn't exist in a bank (such as no limiters on the input bank), the gain screen will be shown.
A third press on the same EDIT key will exit editing and return to the current bank's default screen.
Hint: You can quickly check the same setting of any parameter on a bank of channels by double pressing each EDIT key in turn – so to check each output's polarity setting, just press EDIT, press NEXT until Polarity is displayed, then press the next channel's EDIT twice, and so on.
