  • Hi John,

    I apologize about the troubles you're experiencing.

    The TS Sub is capable of taking in a stereo output so it is definitely not common to get a hum out of one side. If you connect the right cable directly into a speaker rather than into the sub, are you getting the same buzz? If so, this may be coming from your sound source or the cable itself.

    If you continue to have trouble, this may indicate a problem with the hardware. Warranty and non-warranty claims are not handled here on the forum but I can point you in the right direction. Here are a couple of options that you could choose from:
