    Hi.

    I have a powering off problem with my Vincent sp 996 amps.
    Amps are connected to a Sony 840 QS integrated via pre out terminals.
    I have a pair of Kef Q1:s, which are driven in biwred mode by Vincents.
    The problem is Vincents to shut down on low level signals in few minutes.
    If i run a multichannel dvd, and main channels are on low level for sometime, power amps shut down.
    I also run a Dali swa12 sub via Sony sub pre out, and the autostart/off works fine with Sony.
    Any suggestions?

    Is there any way of adjusting the trigger sensitivity on the Vincents?....I had a similar problem with a little Parasound amp I was using as an amp for speakers in the kitchen,and ended up having to use the on/off switch instead!

    The only switch on the amp is the power on switch.
    I also opened the box to find out if there was a adjustment for the sensitivity, but did not find any.
    I tried the amps with a JVC portable system, and connected it to the power amps via headphone out terminal. On weak signal amps went to a standby mode (power led blinking), and with some gain from the JVC they started again.
    This does not happen with the Sony...?? Could the Sony provide too weak signal from the pre outs, or could this have something to do with the earth signal?
