DS18 DSP8.8BT 8-Channel In and 8-Channel Out Digital Sound Processor
SETTINGS PAGE OFF ANY SCREEN
On the Settings page you can see what sourcels) you are using and pick between them. You can also see all the Bluetooth devices that you may have paired up to DSP8.8BT app. And choose between Those also.
Down at the bottom are 2 settings:
- Refresh Device list This will be useful when you set up this up with your installer/tuner and you. You can choose installer/tuner and you. You can choose yourself or your installer can pick himself.
- Reset DSP Tuning This is useful if you don’t like your DSP Settings and want to do a clean setup all over again.
BASIC/ ADVANCED SETTINGS
SAVE SETTINGS/ NAME:
This is SUPER important. ALWAYS save settings!! Once you select SAVE on ANY
page it will bring you to the “New Settings” text box as shown to the left.
You have a choice of Basic
Tuning Presets and Advanced
Tuning Presets. The difference is that the BASIC setting… ANYONE can access
it. ADVANCED ONLY you (or whomever you give your password to) can access. It
is best to first save in BASIC and then once refined in your tuning SAVE in
ADVANCED.
YOUR you’ve settings name, for example, BOB6 it will save it to the APP. As
shown Once entered to the left. You can save 10 settings. You may want one set
to show that it is ALL 6dB per octave crossovers… So BOB6 is easy to remember
and then do the same setting but uses 12dB per octave crossover slopes. Call
that one BOB12, that way you can hear the difference in slopes, Or different
EQ settings.
To sync to DSP8.8BT, go back to the SAVE button on the top of each page blue
bar. Click on SAVE and look at your saved sesaved settings Pick the one you
want to be The setting The EQ / GAIN
PHASE/ DELAY setting. Let’s say it is the 66666 saved file that is shown
highlighted to the left. Since it is highlighted it is THE selection.ttings
Pick the one you want to be The setting The EQ / GAIN
PHASE/ DELAY setting. Let’s say it is the 66666 saved file that is shown
highlighted to the left. Since it is highlighted it is THE selection.
To sync data from DSP8.8BT to DSP8.8BT APP, click on the top bar with the white outlined box and arrow pointing down. It takes one minute to sync data from DSP8.8BT With this many settings, you can now pick and choose what your vehicle= sounds like. Be it a car, truck, UTV, motorcycle, or boat. With 8 channels of input and output the DSP8.8BT there are 1,000’s of possibilities EQUALIZER SETTINGS
EQUALIZER SCREEN
This is where ALL the “magic” happens.
There are 31 bands of Parametric Equalizer adjustments. This means that YOU
can select whatever frequency you need to fix, or bands of frequencies and
easily solve the peaks or dips in your system setup. QUICKLY! You can LOCK the
EQ on this page also. This makes it so you don’t accidentally change an EQ
setting while adjusting something else.
FREQUENCY
Each of the 31 Bands can be changed to ANY frequency you need it to be. Click inside the BLUE boxes at the bottom of each frequency and type the frequency, Q, or boost desired. Since there are 31 bands of adjustment SCROLL Left to Right.
Q ADJUST:
Q (or width) of the frequency is adjusted. Q’s of 1 is very wide, Q of 18 is
very narrow as shown below on the APP itself. To change Q simply slide the
light blue “Q” bar. Or TAP+/
SPECIAL NOTE: An RTA is an ABSOLUTE necessity to adjust ANY audio system that has an equalizer, especially 1/3 octave.
AN EXAMPLE OF FREQUENCY AND Q
The example to the left shows you what happens at a frequency when Q is
adjusted differently at different frequencies. Look at the 1000Hz EQ setting
which has a Q of 20 at the same time 6000Hz has a Q of 1. You can use fewer EQ
adjustments to effect far greater frequencies making EQ adjustment much
quicker. (You MUST have an RTA to properly adjust ANY Equalizer!)
TIME ALIGNMENT
Once we have levels, phase and gains pretty much set.
It’s time to do Time Alignment. Think of all this preset up as prepping a car
to be painted. If you’ve ever painted a car, it’s ALL about the prep work.
Paint (in our case
Time Alignment) is the finishing touches. And up till now it was ALL just
getting ready for this part!
It is important that we do this methodically. Some experts say to Time Align
BEFORE EQ the system. Some say do it after. It is up to YOU. Both ways work.
And we have found that as much EQ you do in this process BEFORE and AFTER it
really doesn’t matter.
Let’s assume that you’ve done some EQ, GAIN and checked to make sure all
speakers are “In Phase”PLUS.. you’ve got the system sounding good. Clean,
smooth, tight with really good mid-bass punch. Then it is the PERFECT time to
do time alignment.
Below is a conceptual picture of what we (you?) are trying to do. Get speakers
that are at different physical dimensions away from your ears to be time
coherent.
Meaning move them electronically so they SEEM to be at the same time /distance
dimension.
Thereby creating the illusion of stereo imaging and sound stage Where the sound does not appear to be coming for the left or right, but in front of you. And out on the hood of the vehicle Plus the woofer sounding like it is under the dash on front of you.. even though the woofer is actually in the trunk of the vehicle.
FINAL SETTINGS
At this point, you are pretty much done, we recommend that you live with the
initial setup (EQ / Time Delay /Gains) for a week and THEN make adjustments.
Also do not spend to0 much time “tweaking” the system. Once you have gains set
CORRECTLY and have checked “Phase” acoustically (with a Phase Meter which is
built into the Audio Tools APP) Spend LESS than 45 minutes EQ your system.
Then take a break as your ears and brain will be charcoal!! Rest your ears
overnight and listen again in the morning. 45 Minutes is plenty of time to get
a system initially “dialed in'”You need to “live” with it for a bit BEFORE
randomly changing settings.
ONCE MORE TIME! SAVE/SYNC
Now click on the top bar with the white outlined box and arrow pointing down
let’s make sure that this LAST”tune” is SAVED and SYNCED to the DSP8.8BT.
Double check that all the EQ settings/Time Alignment/Gains,ett. Are as you set
them and nothing has changed.
When you tap it, upload the DSP data setting from the device back to APP. It
takes around one minute to upload data to prevent data package dropout.
This is used for data from device to APP. When you select the saved file, the
data is from APP to device.
They have reversed the data sync direction.
For example, your DSP tuning is done for a while, but you want another
installer to re-tune it, he might need to know what the current DSP data setup
is. So that he can start from there. Or, if you like some other vehicles DSP
tuning (using DSP8.8BT APP) and you want to get their data, you can connect to
his vehicle with the DSP8.8BT APP with its amplifier, and upload it into your
DSP8,8BT APP, and then load it into one of your 5 memories.
