@ Hoyt
This is the response I got from an ARC rep a while ago on setting up PSM. It's a little vague if you ask me, I'd really like to know what ALL the VU Meters reflect, mostly overall end volume. After you tune you lose a little. How do you know where to get back to. Raising master is raising gains as well. I guess just hope for no distortion? Weird...

Source Unit:

Set your source unit to flat if it is an aftermarket headunit (all headunit signal processing functions turned off)

If using a 2014+ Harley OEM radio as your source, then do the following:

1. Set BASS to 2 clicks above minimum
2. Sett TREBLE to center
3. Set the Speed Volume feature to OFF

Amplifier:

1. Ideally when using a PSM for signal processing, you should set your amplifier crossovers at ALL PASS or FULL PASS and make all crossover adjustments on the PSM.
2. Set your amplifier gains to approximately 60%.

PSM Initialization:

1. Set your PSM master gain -10 to -15.
2. Set your PSM individual channel gains to 0.
3. On the PSM GUI, click on “Meters” (top left) and select “Open Meters”
4. Play full range pink noise with headunit volume at 70%.
5. On the PSM GUI “Setup” tab, select the “Input Sensitivity” voltage that shows the input meters tipping into the red but not staying in red. (You will most likely be setting at 1-volt or 2-volts)

System Tuning:

1. Once you have completed the system initialization steps you can move on to tuning.
2. After you have completed EQ settings for all your channels, you can go to the PSM GUI “Outputs” tab and reduce gains for the channels that seem to be playing louder than others. (Use the channel mute features along the bottom of the GUI to help you adjust channel gains)
3. After you have adjusted individual channel gains you can adjust the master gain with headunit volume at 70%.
4. *Please note: you may have to decrease some EQ levels as you adjust the master gain up
5. The goal is to have all speakers playing distortion-free with similar volume outputs.
6. The master gain DOES NOT have to be adjusted up to 0. Most likely you will be at -5 to -10 when done tuning

Then I asked about input sensitivty :
When using the input sensitivity 2v seems a little high according to meters, 4v seems a little low. Can these be adjusted in the mixer section?

Response :

Set it to 4V and adjust the gain up on each active channel in the mixer

 

At any point in your conversation with Arc did you mention that your HU had been flashed? Pretty sure the instructions they gave you are based on a HD HU that has not been flashed and is their attempt at defeating the stock EQ curve.

 

Dang I forgot you Rushmore guys have a completely different signal feeding that device than the rest of us do. I'm sure all the adjustments would have to be different. Looks like a completely different learning curve versus starting off with a flat signal. I imagine your input and output sliders would probably be a good bit different.

Thanks for posting that response from Arc it's good info.

 

@ Bates
Yes I did mention it..

He asked...What is your source unit?

Harley OEM radio?

Aftermarket radio?

My Response :

Harley 6.5 gt with 8/2 flash.

 

You know I wonder if the guy at Arc really understood what you meant when you told him about the flash. Turning the bass all the way down sounds like he was trying to dodge the low frequency bump of a stock flash.

 

Yes....exactly that.

 

Maybe?... On to other news, I did what you all knew already I uncapped the Hertz in the lids and let'em run. My original experiment was epic failure. Unleashed with a small tweak they sounded awesome, its more work on the Mmats I need, leaving the Hertz alone. Got to get rid of some high end on the Mmats I'll try that by messing with the EQ some more and not so much cutoff like suggested. All in all it's not horrible, just not where I want it. Everything in time I guess... thx.

 

Keep plugging at it, you'll eventually get it. Are you using the Mobile Tools app and pink noise to isolate when tuning?

 

Yeah, and bought that little Dayton mic for the iPad just got it today. Pretty cool, just ironic. I have a bunch of mics, SM57’s 58’s, AT Omni’s and this little thing for 25 bucks!

 

Very kewl.
