About this Guide
This user guide contains installation, configuration, and operating information for the Extron DMP 44 xi. NOTE: Throughout this guide, the general terms “DMP,” and “processor” are used interchangeably to refer to
the DMP 44 xi.
About the DMP 44 xi
The DMP 44 xi, digital audio matrix processor, is a compact, standalone audio mixer with four line-level inputs and four line-level outputs. It features a digital signal processing platform for audio signal routing and control and offers several audio digital signal processing (DSP) tools for mixing, routing, and room optimization. All configuration of DSP processors and the matrix mixer is performed using the Extron DSP Configurator Pro from a host computer via RS-232 or USB communication ports. Two operational modes, Live and Emulate, allow for working offline from the DMP to set up a configuration and create presets and group controls as needed before loading the configuration to the processor. DSP settings developed offline can be saved to the disk as a configuration file that can be uploaded to the device at a later time or can be transferred directly to the device by switching to live mode. Up to 16 user presets and up to 16 group master controls can be created and stored on the DMP. Control systems connected to the DMP 44 xi by RS-232 or USB can control a subset of device functions using Extron Simple Instruction Set (SIS) commands.
Features
· 4×4 line level digital audio matrix mixer — The DMP 44 xi is a compact matrix mixer with DSP. It features four line level inputs that can be processed, mixed, and routed to four line level outputs.
· Inputs: Four balanced or unbalanced line level on two 3.5 mm, 6-pole captive screw connectors · Outputs: Four balanced or unbalanced line level on two 3.5 mm, 6-pole captive screw connectors · Digital audio signal processing on all inputs and outputs · Expanded dynamics and filter DSP blocks — Comprehensive dynamics block includes compression,
limiting, AGC, gating, and ducking. Filter DSP includes 4th order HPF/LPF. · DSP Configurator Pro provides an intuitive graphical user environment — A powerful and user-friendly
PC-based software tool for managing all audio operations of the DMP 44 xi. It enables complete setup and configuration of digital audio processing tools with a clear view of all inputs and outputs, audio processing blocks, routing, and mix points in a single window. · Four digital input ports for remote triggering — Four configurable digital input ports are provided, so that external switches and sensors can be connected to the mixer for remote triggering of functions within the DMP 44 xi. · Predictable, low latency hardware DSP — Input to output latency is fixed within the DMP 44 xi, regardless of the number of active channels or processes. Predictable, low latency processing keeps audio in sync with video, and prevents distractions to a presenter resulting from delayed live audio.
DMP 44 xi · Introduction 1

· 24-bit/48 kHz analog-to-digital and digital-to-analog converters — High performance converters preserve audio signal integrity in input and output signal conversion, while maintaining latency under 1 ms.
· Front panel USB-C configuration port — Enables easy configuration via DSP Configurator Pro while the unit is installed.
· RS-232 control port — Using serial commands, the DMP 44 xi can be integrated into a control system. Extron products use the SIS command protocol, a set of basic ASCII code commands that allow for quick and easy programming.
· Building Blocks processor settings — A collection of Extron-designed processor settings optimized for specific types of input or output devices, such as microphones and Extron speakers, with preset levels, filters, dynamics, and more. Flexible Building Blocks are available on each I/O strip and allow system designers to fully customize and save their own Building Blocks, further streamlining audio system design and integration.
· Live and Emulate operating modes with configuration file saving — Live mode allows integrators to connect to the DMP 44 xi with DSP Configurator Pro to make live parameter adjustments while hearing or metering them in real-time. This avoids the need to compile and upload a configuration file to the DSP. Emulation mode allows settings to be configured offline, then uploaded to the DMP 44 xi. The software also downloads configuration files from the mixer for archiving.
· Sixteen DSP Configurator Pro presets — Using DSP Configurator Pro, any or all parameters for DSP processing, levels, or routing can be saved as presets.
· Group masters — The DMP 44 xi provides the capability to consolidate gain or mute control throughout the system. Gain or mute controls can be selected and added to a group master, which can then be controlled by a single master fader or mute control. Up to 16 group masters can be created.
· Soft limits provide optimal group master adjustment range — The group master volume range can be limited using soft limits to maintain optimal minimum and maximum levels when using external volume control. This prevents operators from over or under-adjusting levels when using digital input or RS-232 control. DSP Configurator Pro provides quick drag-and-drop adjustment of soft limits from the Group Controls screen.
· Rack-mountable 1U, quarter rack width metal enclosure · External Extron Everlast power supply included, replacement part #70-1175-01 — Provides worldwide
power compatibility with high-demonstrated reliability and low power consumption. This power supply is compatible with the ZipClip 50 Mounting Kit. · Extron Everlast Power Supply is covered by a 7-year parts and labor warranty

Figure 3. Rear Panel Features
A Power port — Connect the included external 12 V power supply to the 2-pole, 3.5 mm captive screw
connector. Follow the power supply wiring instructions starting on page 5 to wire the connector to the power supply.
CAUTION: The DC output cables must be kept separate from each other while the power supply is plugged in. Remove power before wiring.
ATTENTION: Les câbles de sortie CC doivent être séparés les uns des autres tant que la source d’alimentation est branchée. Coupez l’alimentation avant d’effectuer les raccordements.
ATTENTION:
· Do not tin the wire leads before installing into the connector. Tinned wires are not as secure in the connector and could be pulled out. They may also break after being bent several times.
· Ne pas étamer les conducteurs avant de les insérer dans le connecteur. Les câbles étamés ne sont pas aussi bien fixés dans le connecteur et pourraient être tirés. Ils peuvent aussi se casser après avoir été pliés plusieurs fois.
· Always use a power supply supplied and or specified by Extron. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the end product.
· Utilisez toujours une source d’alimentation fournie ou recommandée par Extron. L’utilisation d’une source d’alimentation non autorisée annule toute conformité réglementaire et peut endommager la source d’alimentation ainsi que le produit final.
· If not provided with a power supply, this product is intended to be supplied by a power source marked “Class 2” or “LPS” and rated at 12 VDC and a minimum of 0.4 A.
· Si ce produit ne dispose pas de sa propre source d’alimentation électrique, il doit être alimenté par une source d’alimentation de classe 2 ou LPS et paramétré à 12 V et 0.4 A minimum.

DMP 44 xi · Installation and Operation 4

ATTENTION:
· The length of the exposed (stripped) copper wires is important. The ideal length is 3/16 inch (5 mm). Longer bare wires can short together. Shorter wires are not as secure in the connectors and could be pulled out.
· La longueur des câbles exposés est primordiale lorsque l’on entreprend de les dénuder. La longueur idéale est de 5 mm (3/16 inches). S’ils sont un peu plus longs, les câbles exposés pourraient se toucher et provoquer un court circuit. S’ils sont un peu plus courts, ils pourraient sortir, même s’ils sont attachés par les vis captives.
· Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities.
· Sauf mention contraire, les adaptateurs AC/DC ne sont pas appropriés pour une utilisation dans les espaces d’aération ou dans les cavités murales.
· The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently fixed to building structure or similar structure.
· Cette installation doit toujours être en accord avec les mesures qui s’applique au National Electrical Code ANSI/NFPA 70, article 725, et au Canadian Electrical Code, partie 1, section 16. La source d’alimentation ne devra pas être fixée de façon permanente à une structure de bâtiment ou à une structure similaire.
· Power supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply and the unit. The ridges on the side of the cord identify the power cord negative lead (see figure 4).
· La polarité de la source d’alimentation est primordiale. Une polarité incorrecte pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté du cordon permettent de repérer le pôle négatif du cordon d’alimentation (voir l’illustration 4).
· To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.
· Pour vérifier la polarité avant la connexion, brancher l’alimentation hors charge et mesurer sa sortie avec un voltmètre.

To wire captive screw connector to the power supply:

1. Cut the DC output cord to the length needed.

2. Strip the jacket to expose 3/16 inches (5 mm) of the conductor wire (see figure 4).

3. Ensure the connections have the correct polarity as shown in figure 4. The wire with ridges is the ground wire.

4. Slide the exposed ends of the wire into the captive screw connector and secure by tightening the screws. 5. Use the supplied tie wrap to strap the power cord to the extended tail of the connector.

A Power LED — Blinks during power up and firmware uploads, and lights solid when the device is operational. B Configuration port — Connect a USB-C cable to a computer to perform the following:
· Control and configure the device via the DSP Configurator Pro software (see the DSP Configurator Pro Help File for details) or SIS commands (see SIS Configuration and Control on page 18 for details)
· Update firmware via the Firmware Loader software (see the Firmware Loader Help File for details).

Operation
Powering the Processor
To power on the processor, plug the external 12 VDC power supply into the rear panel power inlet and into an AC power outlet. Unplug the power supply to power off.
On power up, the front panel power LED (A) and rear panel reset LED (see figure 3, F on page 4) blink twice
then light steadily when the unit is available for operation or configuration. Current mixing and audio processor settings — the current state of the device — are saved in nonvolatile memory within a 10 second time period. When the unit is powered off, all settings are retained. When the unit is powered back on, it recalls settings from the nonvolatile memory. If a configuration was in process during the power down, these saved mix, audio level, and audio DSP processor settings become active.
Resetting
The rear panel RESET button initiates two levels of resets. Use a a pointed stylus, ballpoint pen, or small screwdriver to access the recessed button. See the Reset Modes table for a summary of the resets.
ATTENTION: · Review the reset modes carefully. Using the wrong reset mode may result in unintended loss of flash memory programming, port reassignment, or processor reboot. · Étudier de près les différents modes de réinitialisation. Appliquer le mauvais mode de réinitialisation peut causer une perte inattendue de la programmation de la mémoire flash, une reconfiguration des ports ou une réinitialisation du processeur.

SIS Configuration and Control

Use Simple Instruction Set (SIS) commands to configure the DMP 44 xi. This section provides information about using those commands. Topics include:
· Host Control Ports · Simple Instruction Set Control
· Command and Response Table for SIS Commands

Host Control Ports

Rear Panel Remote RS-232 Port

The DMP 44 xi has a rear panel remote port (see figure 3, E on page 4) that can be connected to a host device,
such as a computer running Extron DataViewer or HyperTerminal utilities, available at www.extron.com. The port makes serial control of the device possible. Use the protocol information listed below to make the connection.

The protocol for the Remote serial port is as follows:

· 38400 baud

· No parity

· 1 stop bit

· 8 data bits

· No flow control

NOTE: The rear panel configuration port requires 38400 baud communication. This speed is higher than most other Extron products. The DMP 44 xi control software automatically sets the connection for the appropriate speed. When using DataViewer or similar application, make sure the host PC or control system is set for 38400 baud.

Front Panel Configuration USB Port
The front panel USB-C type port (see figure 9, B on page 7) can be connected to a computer as a host device
running either the HyperTerminal or DataViewer utilities for control of the device. Once a connection is established, SIS programming can begin.

Simple Instruction Set Control
Host-to-Unit Instructions
SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the transmitter executes the command and sends a response to the host device. All responses from the transmitter to the host end with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string. A string is one or more characters.
Device-Initiated Power-Up Message
When the device completes its start-up, it issues the following message to the host:
© Copyright 2024, Extron DMP 44 xi, V, ] · is the firmware version number · is the part number of the unit

DMP 44 xi · SIS Configuration and Control 18

Using the Command and Response Table

Symbols are used throughout the SIS tables to represent variables in the command response fields. Command and response examples are shown throughout the table. The ASCII to HEX conversion table (see figure 20) is for use with the command and response tables.

Space

ASCII to Hex Conversion Table

·

Figure 20. ASCII to Hex Conversion Table
NOTE: For commands and examples of computer or device responses used in this guide, the character “0” is the number zero and “O” is the capital letter “o”.

Error Responses

When the DMP 44 xi is unable to execute the command, it returns an error response to the host. The error response codes and their descriptions are as follows:

E10 ­ Unrecognized command

E17 ­ Invalid command for signal type

E11 ­ Invalid preset number

E18 ­ System timed out

E12 ­ Invalid port number

E22 ­ Busy

E13 ­ Invalid parameter

E25 ­ Device not present

E14 ­ Not valid for this configuration
