Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems No noise during Room Correction

Oracle64,

A complete new file would be a good idea, no copy and edit.
Isn't user type 1 - All analogue system with mono sub? (read from my 861 RC dialog)
Does that fit to your layout?
If not, you have to retype, and start all over (new files)

Today I created a new configuration file from scratch.
I set the type of the 861 to "Type 2 - All digital, LFE sub".

After setting up the devices and configuring the parameters, I tried the "speaker calibration" and it worked generating noise for each channel.

When I tried the "room correction" it still failed without making a noise.

the program window shows:
...
selecting source
starting measurement of front left (...
setting volume to 87
product status error: st = "Fail"
Measurement failed.

the speaker shows:
CD 50
CD 87
CD 65
goes into standby (green dot)

Other things I also tried:
- removing the analog sub from the configuration
- updating to the latest version of Meridian Config
- Windows 7 user account, running as admin

Can you play any Music on the Source "CD"?

What are the Speakers Typed as? Should be all Type 6.

It could be the Speakers have "CD" Mapped to D2. Highly unlikely, but is possible.

It's bizarre that Speaker Cal works but MRC doesn't make sound.

One other thing to play with, if you right click in the Measure Tab and Click New

You can choose which speakers to Measure. Try skipping the fronts and see if the rears or any other speakers work. If some speakers work and not others it might give a hint of where the problem is.

Thanks for the suggestions Fiddler.

I simplified my configuration to only a CD player and Sooloos (ID40).

I connected a DVD player with analog outputs into the Analog Input to play a CD - the result no sound. I used both the front button on the 861 and the remote control to select the CD source. I also tried connecting to A1 and A3 on the analog input card and updating the config accordingly.

I confirmed that the DVD player was actually playing the CD by connecting into a stereo receiver that is connected to my TV in another room. It worked as expected.

Back to the Meridian system, the Sooloos worked perfectly.

When selecting the CD input, the speakers and the 861 all show CD Stereo and the volume, but no sound comes from the speakers.

This is a clue, but I am not sure what it means?

Which power supply do you have in the 861? I have had an 861v4 and an 861v6 each of which started to exhibit erratic and puzzling symptoms (they still worked but were very unpredictable) and in both cases it was the power supply (the v6 was just under 3 years old). If you can check the 5volt line then do so - it should be set to 5.2v. If you think the power supply is OK then I would reload the firmware and try again.

Could it be that your analogue input card isn't working? You don't have any sound out of it.

I my situation I don't hear any sound with room correction but I can play music through the analogue inputs.

Did you set the CD source to that analogue input?

It does have the upgraded linear power supply, so I didn't think of checking the power supply voltage. Do you just check it directly on the wire coming from the power supply?

Yes, it shows an analog connection from the "A" on the CD source to the Analog Input card.

I tried both A1 and A3 building a new configuration and downloading for each.

If you have the linear power supply then you are much less likely to have a power supply problem. You could check the 5v and 12v lines where they emerge from the capacitor board ( the multi way connectors near the motherboard) but I would first reload the firmware, type the unit and then try again. If that doesn't get you anywhere try removing all cards from the unit except the bare minimum (one input card and one output card only) just in case you have a card failing. It wouldn't eliminate those cards of course, nor the internal processing cards, but it might narrow down the variables a bit. I had elusive trouble with an ID40. It crashed as soon as I asked it to play audio but everything else in the 861 seemed ok. It turnrd out to be a rogue tape card. When removed everything was perfect.

That is a hint

I think your speakers might have CD Source mapped oddly.

One experiment you could try is, while playing the CD try moving the input on your main speakers from D1 to D2. If that works they are TYPED wrong or manually mapped wrong. Could be only CD is mapped wrong which why everything works.

You could be TYPE 5 and some sources will be on D1 and some on D2.

And/Or try retyping them to Type 6. That Puts all Sources on D1.

I retyped all of the speakers to type 6, and double checked that D1 was connected on each speaker -- the result: no change the CD input still didn't work.

The next thing I will try is making the left main speaker the Master instead of the center speaker. I will update the configuration, reconfigure the master/slave setting on the speakers and then swap the M5/S5 cables on the two speakers.
