Here you go Mark, what do you think?
I have restored previous EQs.

RP Sept 2019, subs set to 1/4 gain, RP sub level +24.3db (true distance for subs from MLP)
RP Jan 2020, subs set to zero gain, RP sub level -7db (added extra 3' to real measuement, Tom requested)
RP Jan 2020, subs set to 1/4 gain, RP sub level + 32.1db (added extra 3' to real measurment, Tom requested)

All the other speaker dbs are similar, the results are different for the sub levels.

@joerod , is having +trims normal with RoomPerfect on the MX-160? To this extent? It is not normal on the MP-50 IME. The numbers do not jive with at all with my expectations based on the speaker sensitivities.

As long as things sound great, I say return to the most recent calibration and enjoy.

BTW, when did you upgrade to V1812s? Neo or IPAL drivers? Your impressions?

Thanks Mark, would be keen to know if you can test the MTM-210s for me and see what the result might be. Maybe the 160 performs different in level gains to the MP50?

Ive had my four V1812s now for approx 2 years, they are wonderful subs.

Murray, you must either have the older V1800s or V1801s then. The V1811s have the PSA amp (with XLR) but same driver as the V1801. The V1812 has newer drivers available. I assumed you had upgraded your drivers. Perhaps the amp must be swapped with the driver update, I'm not sure. @basshead81 ? @Hopinater ? @Tom V ? I'm out of the loop on upgrades for existing cabs.

Mx160/170 v3.6.6

Yes l, this was fast! Long weekend...

You know the drill:

3.6.6 Release Notes:
- Fixed missing Center channel on PCM multi-channel soundtracks.
- Fixed possible crash at system boot-up.
- RoomPerfect Focus position names are now correctly stored.
- Web page and front Info display would indicate 9.1.4 when decoding 9.1.6.

Send me a PM with your email and I will shoot it to you.

If I have sent you then before then just send me an email and I will reply with it.

V1812 has only been out for a couple months...he must mean the V1801's.

“joerod, is having +trims normal with RoomPerfect on the MX-160? To this extent? It is not normal on the MP-50 IME. The numbers do “not jive with at all with my expectations based on the speaker sensitivities.”

Yes, the “+ Trims” is normal now. It’s the new way that Lyngdorf is trying to display the relative differences.

They tried to explain it in their Release Notes, even though it doesn’t specifically say “+” or “-“.
They were just trying to reassure people that the change they see is OK.

https://lyngdorf.com/downloads/lyngd...p-60-software/

MP50/60: Note regarding RoomPerfect gains in installer menu – “Channel gain” page:
/The RoomPerfect levels you see on the gains page, have been normalized in recent Software. That means the channel that plays the loudest is displayed as 0dB.
//So the absolute number is not important, what you can see from them, is the difference between the channels. And if LFE is 0dB, that means it's the one we've measured to be the highest. If he looks at the differences between the channels, they should be the same as with old SW.

So this now means all my + measurements are ok Mark?

Thanks for the email joe. My MX170 is still not passing video when my Sony projector (695ES) is set to enhanced (18 Gb). Yes I’ve unplugged/reset the projector after changing this setting. Still nothing, only works on standard (barely). When it’s set to standard a lot of the time the projector go back and forth from signal/no signal and I have to unplug hdmi (going to the projector) from the mx170 them plug back in. My dealer and I have tried EVERYTHING. Factory resets, testing all cables, sources, different firmwares (expect this last one). Do you think 3.6.6 would help? It won’t even pass Dolby Atmos audio, only legacy Dolby digital and 2 channel audio. Any ideas?

I have a message into “support” for you. First question though is which hdmi cable are you using? Second, in the menu (set up) for the 170 do you have HDR enabled? Make sure your hdmi out matches your main out in the set up GUI. Let’s see if getting an image solves Atmos.

I am using an Audioquest 10M Cinnamon cable. You may want to consider just for fun trying a different hdmi cable. Maybe just run it direct from the 170 to your projector. I’m not saying for sure it’s not the 170 acting up but at least we could rule it out one way or another. Maybe your dealer has one you can try (different model) or you can get one from somewhere with easy returns just in case.

Double check the arrows on the active cable. It will only work one way.

So, just today got my MX 170 installed. Ran RP, at the end RP said 98 percent. When I looked at the room dimensions they are all zero.
WHy might that be?

Next, when I tune in Netflix, choose a 4k UHD movie, it comes out at 1080p from my ROKU. I have ROKU set for Auto Detect, then tried forcing it to HD UHD 30 hz then 60 hz, MX 170 reports at the UHD 60 hz video is unknown.

Ooperator error? Watcha think?

What are room dimensions? If you mean the speaker distance, they have to be entered manually. RP does not do this. SJ

Good Morning;

Anyone have any idea why my USB ports are not seeing my thumb drives, either one of the two. I have tried numerous drives and still no luck. All my computers see the thumb drives and the software update. The MX170 is silent on these USB ports!

Am I missing a setting?

Does the MX170 control illumination of McIntosh gear with the stereo mini cable? The MX123 shows the illumination control pinout in the manual but I am not finding a way to turn amp illumination off like some pre-amps.

Yes. See Page 10 of the MX170 manual for the pin-out and Page 12 for instructions on how to turn the connected amp light on or off.

Can someone please help me. I played the movie Labour Day last night and my bass from the subs was horrible in some parts, Ive never heard this before. I dont know if they call this ringing or what, but I'll try to describe it...
At the start of the film there is some very longs slow bass notes playing continuously. They seem to get louder and boomer and longer, its almost like the not doesn’t finish, its horrible to hear….. It goes on and on….
Is this called ringing?
I want to stop this, can someone help me please?

I have three fronts PSA MTM-210s and four PSA V1081s up front.
