I recently bought a Velodyne VX-10 from 6th ave. It sounds good, but I have problem with the auto-on feature (it doesnt have a switch for constant on). It doesnt turn on unless I crank up the volume on my reciever way high. The FAQ on their website suggested using Y connector both inputs. I used Monster Y connector and it has a slight improvement in signal sensing, but does not tun on at regular listening levels. Once it turns on it sounds good at low as well as high levels. But it will turn off at moderate level. This is a big problem when watching movies, it wont turn on in a scene with high bass effects. Do all subs have low sensitivity to signals, do they turn on only at high levels ? Is my problem unique, should I have the unit replaced or returned ?
