8351 - Remote Control of Volume with standalone GLM

8351 - Remote Control of Volume with standalone GLM

Padawan Posts: 73 Join Date: 1/4/16 Recent Posts
Hi,
I have the following set up.
8351 connected to GLM 2.0 and a remote control 9101A.
Source is a Squeezebox touch connected to AES/EBU using an apropriate SPDIF to AES/EBU cable.

My question is:
Does the GLM box needs to be connected to the PC for the remote control to operate?

If the GLM box is connected to the PC and the software is running all works fine.
When I try to run the GLM box without connection to the PC (USB power source) I do not get it to work.
At first it works but when I turn the speakers off and on again I have the full digital signal at the speakers.
and the overload protection kicks in. Luckily the squeezebox has a volume controlled digital output but
even when I turned the volume of the squeezebox very low when turning the speakers off and on the red LED flashes without any overload. Which could also mean that there is a digital connection problem.

Do I miss anything here or is it simply not possible?

Thanks

Cheers
Knut

Hi,
I still can't get it to work.
I try to explain what I do step by step.
I connect everythink.
I am running the GLM software the wireless remote control works fine.
I store the settings to the monitors (full level or current level makes no difference in the following behaviour) and I switch the dip switchs of the monitors to "stored".
I disconnect the GLM interface from the computer the wireless remote control still works!
I turn both monitors off and on again the wireless remote control does not work and I hear only music from the left speaker which is connected vie Aes/Ebu from the right speaker. Right speaker LED is green but no music.

I do not know if I am doing something wrong or if this is a general issue?

Any help is highly appreciated.

Thanks and cheers

Hi Knut,

I can confirm that it is not a general issue and volume control should work normally after a boot. Can you please send your GLM setup file to SAM@genelec.com ?

Hi Knut,

Than you for the file, everything looks good there. Do you have any spare Cat5 cables laying around? I would recommend to change both cables and see if the problems disappear.

Hi Ilkka,
thanks for the feedback.
I will do that and let you know the result.

Just a short question for clarification (because I found somewhere different statements regarding my question).
When exactly do I have to switch on the "stored" switch?
Before I have send the data to the speakers or after I have send the data?

Thx
Cheers

"Stored" switch should always be enabled in normal conditions. Unless it's enabled, you can not store the settings permanently into the speaker.

Very similar problem here. Two new 8351 connected via AES. While the GLM is connected to the pc the volume control works fine. Also with the 9101A wireless remote control. After disconnecting the USB cable from the pc and connecting it to an USB power supply it continues to work fine. But after switching the boxes off and on again, the sound on left and right channel stays quiet. Turning up the volume with the 9101A does not change anything. Sometimes if turned to maximum volume I can hear a slight sound, but very quiet.
After connecting the GLM to the PC and starting up the GLM software, suddenly the sound re-appears and everything works as expected.

"Stored" swich is on. All others are off. Settings were stored to the speakers.

Maybe I miss something here. Do I have to keep the speakers always on and they lose the setting after they were switched off? Does the USB power supply need to meet some special requirements?

Propably a firmware issue.
Lets wait and see what news Ilkka has about this.

Hi,

Could you let me know the manufacturing date of your speakers? Could you also send your GLM setup file to SAM@genelec.com Thanks!

There is a known problem with certain models when the speakers are connected only to the network interface (no active GLM). The speakers will forget their settings and revert back to default settings after power cycle, that's why there are AES/EBU channel issues and volume control problems.

The affected models are 8240, 8250, 8260 and 1238CF. Other models do not have this issue.

We are working on a firmware update which will be available soon. I am sorry for the trouble.

Hi,

thanks for the quick reply. Manufacturing date is 02/2016. Setup files are mailed.

It seems getting worse. At the moment the LED of both speakers is not stable green as before but switching between green and red within every few seconds. Sound is sometimes lost for the part of a second. (*)

And just now the worst case I could think of happend. I switched off one of the speakers and then on again after a minute. Suddenly the volume was at maximum and the remote control did not respond. I almost got an heart attack and immediately switched off the power to the speakers. Now I'm getting a little afraid if this will happen again.

(*) Addition
The problem with losing the digital audio signal (LED flashing red / green) could be a problem with my connected SAT receiver (vu+ Duo2). If switching the source signal to a BluRay player or to a Samsung TV (HDMI ARC) everything works fine. The SAT receiver seems to work sometimes, but sometimes not.

For the time beeing keep the GLM box connected to the computer and everything works fine.
We just have to wait until they fixed the firmware of the speakers.

I would also be interested in the firmware update for 8240A. My setup of GLM2 standalone with 9310A volume control, 7260A and a pair of 8240A behaves erradically when GLM2 is kept powered on while 8240As and 7260 will be powered off. Both the maximum volume level and left/right channel settings seem to be lost. Removing and restoring the usb power from GLM2 seems to fix them.

Hi,

Could you please send email to SAM@genelec.com so that I will have your email address? I will contact you once the firmware update for your speakers is available. Thank you!

Firmware update 8240A 2 0008 0070 0170 seems to have fixed the issue. Thank you.

What is the default state after losing 8250A's stored settings after power cycle when analog inputs are used? Will it default to maximum attenuation?

Latest firmware is installed to the monitors and setup is stored to the monitors at full level.

What else could be the problem is speaker doesnt produce sound when stored dip is on?

Would it be possible that NVRAM battery has expired? Or what kind of memory is used in the 8250A monitor?

Hi!

 

If the GLM network interface is connected to the speakers with the network cables, and the interface is connected to the computer USB port, but the GLM software is NOT running, this will result with a system MUTE. So always when you have the interface connected to the computer, you need to have GLM software running. Or then you need to disconnect the interface from the USB port and power cycle the speakers to get the stored setting loaded.

 

Best Regards, Markus

Hi Markus, thanks. This could be the case if GML adapter was connected, but it isn't. Is it possible to reset the monitor to factory settings somehow if there is something stuck in the operating system.

Br, Jani

Hi,

 

So you mean the monitors doesn't play sound at all when stored dip is ON? If so, please download latest GLM 3 Beta from link below, update monitors and adapter firmware. Then calibrate your system, and go to Group|Store current settings at full level to SAM monitors| -> Remove GLM adapter from PC -> Restart monitors-> Does it work now?

 

Please send an answer to service@genelec.com, and lets continue the problem shooting there, and I can give instructions to send it to service if needed. You can contact us in English or Finnish.
