Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Constant Buzz/Beep Tone from my 568.2mm

While my daughter was watching a movie, about 2/3rd's of the way through the movie a constand loud buzz/beeping tone was emitted from the speakers. It scared the hell out of everyone.

At the time I was in bed asleep sick with a stomach virus when this sound started and got me out of my beauty sleep, what a rude awakening. I thought holy crap, what the hell was that. I didn't know what it was. I thought it was my alarm clock or my mobile, a sound you don't normally hear every day.

My wife walked in and said the sound came from the speakers. I thought.....[censored].....I've blown my speakers AGAIN. I posted a thread a little while ago on here about how my tweeters were cooked on my JBL XPL-200 speakers. The culprit being my Lavry DA10 and a misconfigured 568.2mm.

Unfortunately for me, some damage has occured on all my drivers. All DCR values on all the drivers have dropped slightly since last testing them when I slotted in the replacement tweeters.

Instead of white noise, I got this noise out of stargate, like when they open the doors to their underground facility but with a constant beep tone added in. I checked the 568 and noticed it had lost audio sync with the DVD player. Using the remote or the buttons on the 568 did not work so I had to do a hard reset in order for it to work again and pick up the sound from my DVD player.

I've never had this buzzin/beeping sound before but I've had occasions where the 568 has lost audio sync with the DVD player when changing discs and sometime the 568 would lock up completely and have had to turn it off to get it going again.

I have the DVD player connected to the 568 using Meridian's blue digital cable. The DVD player is a cheapie $50 MTV DVD player and I'm wondering if this is the culprit in this case.

What would cause the Meridian to emit such a beep/buzz sound? Is there a preference as to whether it is better to use coax digital over optical? I've always thought coax digital was a sweeter warmer sound as opposed to the more clinical/harsher sound of optical? Is this problem that I'm having only inherit to using digital? Would I have had the same problem if I used RCA?

Has anyone had any experience with a buzz/beep sound coming from their Meridian processors in the middle of listening to music or movies? I don't know whether or not this is specific to the 568's or if this hapens to processors across the Meridian board.

I'm starting to loose faith with my 568.2mm and ever since I've had it in the system, I've had these hiccups on the way. The first one was my fault but this buzz tome is presume is 568's own doing. I want to love the 568.2mm but it's doing a damn good job of trying to rid itself from my system.

Is it common for processors to lockup occasionally or lose audio sync with devices? I'm wondering if this was a problem that already existed by the previous owner and is why they got rid of it? Mine was from a deceased estate sale so I would think not.
