    Not much info to go on im afraid.
    A work colleague has a Yamaha receiver and a Pioneer DVD. He has a 6.1 setup and the sub is connected via a phono type lead between Sub out on the receiver and line in on the sub. Unfortunately he couldnt remember the Yammy model number but believes its from the RX range ? Anyway everytime he switches sound modes I believe the sub "bumps" in his words
    Any ideas anyone??

    it's supposed to, every sub gives a slight 'kick' when its turned on.
    If it's switched on but the plug is off and then flicked on (not the proper way to do it) you'll hear a much louder bump.

    Hi Malone
    Dennis off this forum had the very same trouble with his sub.What had happened was that he'd been pulling the subs phono lead out when powered up this in turn damaged a capacitor in the amp which blocks noise when switching modes.Dont think it was expensive to get repaired.
    Hope this helps Gonzo.
