MX8700 Computer Control

NOTE

: It is only necessary to connect a computer to the MX8700 if you wish to change the loudspeaker

model for which the MX8700 is configured.  EAW’s MXLoader program must be installed on your computer
in order to communicate with the MX8700. Different preset files are available from EAW for all applicable
products either on the EAW web site or by contacting the factory.

Use the rear panel RS-232 9-pin female connector for connecting to a computer to download a different
EAW loudspeaker preset.  The RS-232 port uses the following protocol: 9600 baud (minimum), 8 bits, no
parity, 1 stop bit (8N1).  

4.4.1 Downloading a Different Preset:

The MXLoader program is used to download presets to the MX8700 using an RS232 interface. The
MXLoader program requires an IBM compatible PC equipped as follows:

Operating System: Windows 98, 2000, ME. NT (Do not use with Windows 95)

I/O: An unused serial port, preferably accessible via a DB9 connector.

1. Obtain a copy of the MXLoader program by downloading it from the EAW web site:
http://www.eaw.com/ and go to the “Downloads” page or contact the factory and a copy will be sent to
you on a CD-ROM.

If downloaded from the web site, run the “setup.exe” file and follow the instructions in the install pro-
gram. An entry will be made in your “Start/Programs” menu and shortcut icon “EAW MXLoader” will be
put on your desktop.  

2. Download the loudspeaker preset file you wish to use. The file will be “451xxx.mxl” where xxx will
be a number corresponding to the particular preset. Save this in the same folder as the MXLoader.exe
program.

Files available from EAW include:

451xxx.mxl

preset file

451xxx.mxl.txt text file of the *.mxl file contents
451xxx_c.pdf

sheet listing all parameters for the preset

451xxx_l.pdf

labels for presets

3. Click on the downloaded “451xxx.mxl” file which will automatically start the MXLoader program.
You will be prompted to type in the number of the COM port (1,2,3, etc.) connected to the MX8700.
The default COM port in the program is “1”.

4. Choose where you want to load the preset: left channel, right channel or both channels. The
default is both. Click 

OK

. The file will automatically download to and reconfigure the MX8700 for the

new preset.

NOTES:

1. Only one loudspeaker preset at a time can be resident in the MX8700.

2. You can also open the MXLoader program by double-clicking on the EAW MXLoader desktop icon
or click 

Start/Programs/EAW MXLoader/EAW MXLoader

.  Then, from within the program, browse

for the desired “451xxx.mxl” file you want to load into the MX8700.

WARNING

: Downloading a new preset into the MX8700 will overwrite the previous preset loaded

into the MX8700.  Using the wrong preset with a loudspeaker can result in damage to the loud-
speaker.  Be sure you are loading the correct preset for your loudspeaker before continuing.  If in
doubt about what preset is already loaded, simply obtain the correct preset from EAW and load it
into the MX8700.
