The File Menu
Saving your work is critical. Whenever you have the PC connected to your DSP all the
work you are currently doing is at risk of being lost if something should happen to cause
a loss of power to the system or to close the GUI prematurely. So, like anything else in a
computer, save and save often. Saving and Loading of files and presets is through the
FILE menu in the upper left corner of the GUI (Point 1, Pag. 14).
The file menu allows you to:
1. Open a file that has been stored on your computer.
2. Save a file that you want saved on the computer.
3. Save As lets you choose a location to save the file in**
4. Factory Setting will let you completely erase all
current settings.
5. Write to Device puts the current settings into a
DSP memory preset.
6. Read from Device loads a saved memory preset
from the DSP.
7. Delete from Device allows you to delete one or
more presets from the DSP.
** For saving files to the PC you should create a sub folder named DSP Settings. The first time you
save a file you click Save As and navigate to your DSP Settings folder. Then highlight the system’s
file name, enter a name you create and click Save. Occasionally you may need to do this a couple
of times but usually after the first time that you Save a file and Open a file those functions will
automatically take you directly to the correct folder.
Write to Device will open the memory preset
menu. There you can choose to save in any of 10
preset positions. Unused positions have a green
background while the currently used presets have
a red background. Click Select Save Place and
choose a green position. If you select a red position,
you will overwrite whatever is there with the new
parameters. When you click Save you will be asked
to give a name for the preset. You choose a name
and click OK and the preset will be saved. You will
see the save progress and then system will tell you
the save was successful.
Read from Device works the same way. You will get the Read from Device menu and at
the bottom you can Select Read Place, choosing any of the saved memory positions, and
then click Read to load the settings of that memory preset into the DSP. Delete from
Device opens a similar menu screen, and you choose the preset you no longer want and
click Delete. The Delete menu will stay open so you can delete more than one preset if
you wish. When finished you can click the X to close the menu.
Manual Setup without Auto Calibration
As explained earlier in reviewing the GUI, the process will start by choosing your input
setup as 2-Ch, 4-Ch, etc. and summing channels, if needed, to get a full range signal from
a factory head unit. Then you can name the channels and set the crossovers as per the
recommendations of the speaker makers. You need to also measure the distance from
the listening position to each speaker center as accurately as you can and let the GUI
calculate the delay for each speaker.
Begin phase check: R/L Balance in the middle
A. Tweeters: Click to Mute all channels except the tweeters. Note that tweeters are the
most difficult to phase. They are the smallest drivers and are not loud. You need complete
quiet. Play a music track of female vocal and notice where the vocal originates (you may
need to lower the crossover point for this. If so, keep the volume low and you may want
to use a 48 dB slope, so you do not blow tweeters. We have already set the calculated
delay, so the vocal should come from a specific location near the center of the windshield.
If the tweeters are not correctly in-phase, then the sound will not have a specific location.
It will splash and seem to come from everywhere at the same time. You will not be able
to locate the sound at a specific spot. To the left of the Delay bars you see the Phase
buttons. All should say 0 at this point. Click the Right channel tweeter to 180 and listen
for the difference. Do this a few times and you will see that in one position the vocal is
easily located near the center of the window while in the other it seems to come from
everywhere and cannot be located. Obviously, you want the right speaker to be in the
polarity that puts it in phase with the left, so the image is centered in the middle of the
dash. Note: Once you establish the proper phase combination of a pair of speakers, it
never changes. You do not change one without changing the other as they are now a
matched pair. If you have changed the crossovers of the tweeters for phase check, you
can put them back to normal now.
