2. With the subs plugged into the HD and REW up and running, we get sound rom the subs when playing the pink noise from the signal generator but none when we test the sub individually in the PC's control panel. We get from the speakers but not the subs.

So I assume the issue is in the HD. Could anyone identify what may be the issue?
If the output from REW when sending the test signal is from HDMI4, then you are sending an LFE signal. If you are not getting any sound from the AVR when viewing movie content, the first thing I would check would be whether the speakers are set to “Small”. If the speakers are “Large”, there would be no signal to to the subs.

Unless the sub channel is set to "Plus" or the equivalent.

Thanks AJ. Another thing to note is that when we set the option to hdmi output 4 we get nothing even in the generator. But when we set it to minidsp hdmi 1, that's when we get sound.

I reboted the Minidsp, run YPAO again and now bass are back to normal and clean.

I know the dip at 60 is very annoying but I only have two option. Sub on the left with the dip at 60Hz or sub on the right with a huge dip from 80Hz to 120Hz and my center channel has to be crossed over at 100Hz. That's why I got the MiniDSP. I need a second DIY sub, they must be build tailored and only 8". The room is small so that's ok.

That’s because the WI-DG is a buggy device. In fact, I’d call it the worst piece of Wi-Fi tech that I’ve dealt with in a long time.

I fought similar intermittent issues like you’re fighting for 3+ hours and then I gave up. I bought a 25 foot USB extension cable, connected to my 4 x 10 directly, and moved on with my life. I’ve had zero connection problems since. Save yourself some trouble and switch to USB.

I would check Windows "Sound" playback tab and make sure it did not revert back to stereo. It needs to be 5.1 or 7.1 depending on your system.

For now I want to try their instructions and see what happens. Hopefully it will get resolved so I didn't waste my money. I have a 15' cable and it's just not quite long enough to be convenient. I have a 25' in my wish list ready to go though. I've almost purchased it several times, but I thought I read somewhere (maybe it was for the UMIK mic for REW?) that 15' was the max for reliable connection.

15’ is the published maximum “supported” distance for a passive cable. Longer passive cables may work, as Ron has reported. You could also select an active USB cable to be sure it will work:

Did that already and it is on 7.1

I would next try a different HDMI on the AVR.

I bought this and it works for me.

Last night I made a quick treatment with polyfil behind the sub. The dip got much better, earned 10db.
Tonight I will try to make it even better. Now I know what the problem is.

I think my miniDSP died today. I'm hoping someone might have an idea of something else to try to get it working again. Here's what happened:

- It was working last night.
- This morning I disconnected it to take physical measurements on it for 3D printed wall mount that's being designed.
- I hooked everything up the same way it was before. One thing to note is that my system was off at the time.
- I started playing a test tone to verify that I hooked everything back up correctly. Nothing was coming from the subs or BOSS.

So I started trouble shooting it and tried all of the basics:
- Rebooted the miniDSP
- Checked the plugin. It's showing meter lights on all the inputs and outputs.
- I plugged one of the amps directly to my AVR and it played correctly. Putting the miniDSP back in the chain results in no sound. So it's definitely the miniDSP that's the issue.
- In the plugin I did a Factory Reset. No change after it was completed.
- I unplugged it as a long shot when I went to dinner to see if it needed a harder power cycle with no luck.

Everything looks correct. Any suggestions on anything else to try?


Nevermind. I just figured it out and back up and running. Keeping this in case someone else runs into it. It looks like the units are sensitive to the power adapter they're plugged in with. I accidentally used the wrong one. There was one from an old device hanging out that I grabbed by mistake. When I switched to the correct power supply everything started working.

In the BEQ thread it was recommended to lower the input 1 for each decibel one would raise in an EQ. So I have an LS @20hz +5db that I should lower the input level 1 by -5db in order to avoid digital clipping.

I had always lowered the overall master volume of the MiniDSP by -5 dB. Is lowering the input level better/different? Measurement wise I see no difference. I am just curious especially with regards to BassEQ (BEQ).

TIA

You can verify by playing since waves (from REW or other) at 0dB in your AVR, with your subwoofer amplifiers turned off. Look in MiniDSP and see what the levels are at. If you properly gain matched your system before applying any EQ, there should not be any issues - but you can still confirm.
