IUSB Audio Port Connector — Connect a Windows or Mac computer to this mini type B port to interface with the DMP128
Plus as a 4x4 audio interface. Available sample rates are 16 kHz/16-bit up to 48 kHz/24-bit. Refer to the Aux Input section of
the DMP 128 Plus User Guide for more information on USB audio interfacing capabilities.
JReset Button and LED — The reset button returns the DMP 128 Plus to different tiers of default states. When using the reset
function, the LED blinks to signify the different reset modes. When not using the reset function, the LED operates as a power
indicator, matching the front panel LED.
When all connections have been made, power up the input and output devices, then apply power to the DMP 128 Plus.
DSP Configurator Software Installation
After applying power, there are no hardware controls for the DMP 128 Plus. All conguration and control is done using DSP
Congurator. Install DSP Congurator on a PC running Microsoft®Windows®. For full details about computer requirements, see
the DSP Congurator product page at www.extron.com.
To download the DSP Configurator Software from the Extron website:
1. From the Extron home page (www.extron.com), click the Download tab, to open the Download page.
2. Under Software in the left column, select DSP Configurator Software. The DSP Configurator Software product

DMP 128 Plus Configuration
When power is connected to the DMP 128 Plus, an audio source, a power amplier, and speakers, audio output can easily be
tailored to any listening environment. When a different conguration is required, changes can be made using DSP Congurator
setup and control software.
To Configure the DMP 128 Plus:
1. Ensure the control computer is connected to
the Ethernet port (recommended), RS-232 port,
or front panel USB Cong port of the
DMP 128 Plus.
2. Start the DSP Congurator software. From the
splash screen drop-down list, select the
DMP 128 Plus model corresponding to the model
connected to the control computer. Click OK and
the main workspace opens.
3. The program starts in Emulate mode.
a. To create a conguration le ofine and
upload (push) that conguration to the
DMP 128 Plus at a later time, remain in
Emulate mode.
b. To push a conguration to a DMP 128 Plus,
pull the current conguration from a
DMP 128 Plus, or make immediate changes to a DMP 128 Plus, enter Live mode. Live mode can be entered by clicking
Live at the top of the DSP Congurator workspace, selecting Tools > Connect to Device, or by pressing <F6>.
NOTE: When Live mode is selected, a connection dialog box appears. Select the desired connection and follow
the on screen prompts. Refer to the DMP 128 Plus User Guide for more information on actions available in this
connection dialog box.
The main workspace provides access to mix matrices, gain blocks, and DSP processors for conguring a DMP 128 Plus. It also
provides a menu bar across the top for further conguration tools. For more information about using DSP Congurator, see the
DSP Congurator Software section of the DMP 128 Plus User Guide or the DSP Configurator Help le that can be accessed
by selecting Help > Contents or pressing <F1>. Dialog boxes within DSP Congurator also contain context sensitive Help
buttons ( ) in the top right corner of most dialog boxes.
