    Beolabs turning on/off.... harmful?

    Since I connected my BL8K/2 to my new pre-amp all is good.

    However, whenever I mute or pause the sound for a bit - the speakers will turn off (yes, I know part of how they work)

    Is this constant on/off bad for them?

    Is there a way that I can prevent them from going off even if there is no audio signal going to them?

    Working as designed, so it should be safe. Not much you can do about it externally, except just turning down the volume instead of muting.

    I guess it would be just a change of a couple of components in the autostart circuit to alter the time constant for automatic off, but I'm sure it's not worth the trouble.

    Not a techie, but I would suggest that it is good for them to keep switching on and off. A regularly used solenoid/switch/relay is less likely to carbon up. Just a thought.

    Re: Beolabs turning on/off.... harmful?

    Which pre-amp is it?? Some pre-amps have "trigger outputs" which is often 12V. This can easily be converted to 5V, which is, (if I remember correctly), the voltage that Beolabs receive in the Powerlink cables to tell them whether they are on or off.

    If this is possible, the speakers should turn on/off with the pre-amp, instead of the sound.
