    MR18 Power On Start Up Noise

    Hi : I have an MR18 and love it, but it makes a harsh noise on start up (listen to attached file, a zipped mp4, but WARNING: turn down your speakers to their softest level before clicking play!!).

    I have updated the latest firmware to 1.16, but I am still getting this problem. And if I don't remember to turn the volume down, turning on my MR18 is a painful experience.

    Thanks for any help.

    same here

    Hi,

    it was first so unexpected, that I got a ringing in the ears. Really dangerous!

    I have exact the same issue ... is there already a solution?

    I just figured out that there is silence if I select "mute Outputs on power cycle".

    Is this the solution, or however a hardware issue?

    The MR18 works fine besides this issue.

    Regards,
    Patrick

    I have this also and now also have 'Mute on Powerup' selected.

    It seems this is 'normal'. But I would not turn on any mixer (analogue or digital) with the power amps turned up.

    I don't use "mute outputs at power cycle" for one reason, if your unit loses power and remote access has not been established, you will have no sound. if your remote access device breaks or malfunctions and you power on, no sound and no way to get it. With not using the mute function setting, your system powers up where last set at least. The way I get around it without noise is old fashioned but works. Power ON all your amps/speakers LAST, power OFF all your amps/speakers FIRST.

    Me too

    Iím getting the same problem. My best guess is itís some sort of fx feedback loop that happens during the brief period when the routing matrix is uninitialised. Setting mute at power cycle stops it from papering the opposite wall with your speaker cones, but others have pointed out the disadvantages of that setting.

    If itís the routing matrix, it could be solved with a firmware modification, but itís interesting that XR18 owners havenít reported this issue to my knowledge, which might point to the different hardware that Midas use. A/D converters?

    Itís not a major issue for me, but Iím adding my voice here so that Midas know this is a common problem. It would be great if they could solve it in a future update. Itís too good a product to be marred by this issue.

    Does it happen even with a factory scene or just with some types of scenes?
