Page 5: About This User Guide
Introduction About this User Guide This user manual gives a detailed description of the functions of the Martin Audio DX4.0 series advanced loudspeaker processor. Unpacking the Units After unpacking the unit please check carefully for damage. If damage is found, please notify the carrier concerned at once. You, the consignee, must instigate any claim.

Page 8: Compliance
We, Martin Audio Ltd. of Century Point, Halifax Road, High Wycombe, HP12 3SL England, declare under our sole responsibility that the DX4.0 product, comply with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Singapore standard SS145-1:2010. Warning THIS PRODUCT MUST BE EARTHED. Ensure that the earth terminal of the certified cord-set is connected to the protective earthing system of the installation. DX4.0 USER GUIDE V1.0 Copyright © 2020 Martin Audio Ltd.
Page 10: Product Overview
LIR Linear Phase Crossover Filtering The DX4.0 also includes a new type of crossover filtering Linear Impulse Response (LIR) crossover filtering, which results in a linear phase crossover that has a constant delay regardless of frequency (unlike other types of crossover which delay different frequencies to a different extent, thus smearing the arrival time).
Page 11 O-Line The DX4.0 allows control of an O-Line array which has been designed and optimised using DISPLAY 2.3. The d2p file created in DISPLAY can be uploaded to the DX4.0 when the unit is connected and controlled by VU-NET. The routing and all processing will be automatically allocated using the Preset Manager section of VU-NET.

Page 13: Audio Connections
Pin 1 of the XLR connectors is internally connected to the chassis. The shield of the output cable should always be connected Pin 1 of the XLR to ensure that EMC performance and regulations are met. DX4.0 USER GUIDE V1.0 Copyright © 2020 Martin Audio Ltd.
Page 14: Using Unbalanced Connections
The cable shield is connected to pin 1 at the source (this device), and to ground at the destination device (along with the pin 3 ‘cold’ connection). Alternatively, if the cable is a single core plus shield, the cable shield should be terminated to both pins 1 and 3. DX4.0 USER GUIDE V1.0 Copyright © 2020 Martin Audio Ltd.
Page 15: Panel Layouts
Please note that because of the long release time of the thermal limiter, the <˚C> indicator may remain illuminated for several seconds after signal on that channel is reduced. DX4.0 USER GUIDE V1.0 Copyright © 2020 Martin Audio Ltd.
Page 16: Rear Panel
Rear Panel Power Inlet – The DX4.0 unit should be connected to a suitable mains electricity supply using an earthed IEC C14 connection power lead. The processor has a switch mode power supply with a nominal mains voltage of 85V to 240V, 50/60Hz without re-configuration.
Page 17: Operation
Drive Modules The DX4.0 uses Drive Modules to represent loudspeaker sub-systems. Drive Modules result in a less processor-centric and more speaker- orientated system design. A Drive Module is defined as the processing provided by one input DSP, and a number of outputs, which are associated with one another by means of routing.
Page 18: Component Presets
Module Preset. Note: DSP inputs are not the same as physical inputs. The DX4.0 has four audio inputs and four DSP inputs. This is a matrix mixing system where any physical inputs, be they analogue, AES3 or networked audio feeds, can drive any number of DSP inputs.

ModulePreset.Component name). When the desired component is reached, pressing <ENTER> will flash the Enter button. Pressing <ENTER> again will then recall the Component Preset. Note that Component Preset do not contain and do not disturb parameter Overlays. Also see Overlays and Snapshots. DX4.0 USER GUIDE V1.0 Copyright © 2020 Martin Audio Ltd.
Page 20: Aes3 / Dante® Inputs
AES3 / Dante® Inputs In addition to the usual analogue inputs, the DX4.0 can also accept AES3 digital inputs. The same physical XLR sockets are used for both analogue and AES3 inputs; the function of these being determined by the Type parameters in the Input Type menu. The input sockets 1 and 3 are used to input pairs of AES3 channels, so setting the input to "AES3"...
Page 21: Fir Shelving Eq
DSPs can be driven from any one input, or from pairs of inputs "1+2", "3+4", "1+3", "1+4", "2+3" or "2+4". Summed inputs have 6dB of attenuation so that a sum of largely similar programme material remains at the correct calibrated level. DX4.0 USER GUIDE V1.0 Copyright © 2020 Martin Audio Ltd.
Page 22: Output
AES3 & Dante® Outputs In addition to the usual analogue outputs, the DX4.0 also allows outputs to be sent digitally using either AES3 or Dante. The same physical XLR sockets are used for both analogue and AES3 outputs; the function of these being determined by the XLR parameters in the Output Route menu.
Page 23: Limiters
Limiters The DX4.0 includes three limiters in the output signal path. Please note that whilst the limiters in this product offer protection for amplifiers and drivers, they can never protect from all possible scenarios, therefore Martin Audio is not responsible for any damage which might occur.
Page 24: Amplifier Gain
Amplifier Gain Expressed in dB, this is the gain of the amplifier which the output of the DX4.0 is feeding. This value must be entered to allow the DX4.0 to correctly calibrate the thermal and excursion limiter for the amplifier in use.
Page 25: Utility Pages
WARNING – Do NOT use "Static" mode unless your IT system specifically requires it. "Auto" mode should always be used where possible since in this mode, the DX4.0 can always be ‘discovered’ by the VU-NET software. When in "Static" mode, the IP Address will flash on the Home screen.
Page 26: Dhcp
Snapshots A Snapshot may be recalled either via the device User Interface, from the VU-NET application or via the AUX port on the rear of the DX4.0. The Snapshot menu is accessed via the utility pages. Recalling a Snapshot triggers the recalling of a Component to each input and output, and may change other device-wide settings, effectively recalling a processor-wide preset.

Otherwise, press the "Down" button to escape. Alternatively, you can access this feature from VU- NET application using the by right clicking on the DX4.0 icon in the System Diagram and selecting "Reset to defaults".
Page 29: Tipi Control
DX4.0 USER GUIDE Tipi Control Protocol Overview Tipi is a simple but powerful ASCII text based protocol for controlling and monitoring DX4.0 processors from any number of third party control panels or software applications over Ethernet (TCP/IP). Physical Layer Tipi would typically be transported using an Ethernet Interface (10/100/1G) using the TCP/IP protocol, port 51456.

For each type of device, a list of compatible MethodNames is published. Please refer to the documentation for the specific device. Security Not all the published MethodNames will be accessible; some of these might have been ‘locked’ by the vendor. DX4.0 USER GUIDE V1.0 Copyright © 2020 Martin Audio Ltd.
