I have a call into Axiom Tech. Too much going on to sit around waiting for a call back..... Maybe someone has a trick up their sleeve for me to try in the meantime.
One of the twins I unboxed yesterday is making this click-click-click noise. Noticed it when I initiated the Denon's white noise test tone to balance channel levels. I have dual sub output adjustment. Same spot, same cable as the V2 500's these V4's are replacing. Tried turning it off, back on a couple times. Connections are good.
When the clicking occurs, I can see a color change occurring inside the amp cover. Must be an LED. It turns from blue to red.
Can't refer to the instructions (uhhhh, it happens!!), as there were none in the boxes.
Hi Michael,
Does the sub click when there is no signal, or the signal is at low levels, or does is only take place at high levels? The LEDs you see changing colour through the cooling vents suggests that the amplifier is going into protection for some reason. I am suspecting a wire harness may have come loose during shipping, even though we have not run into this before. The amplifier used in the v4 is a proven design and has been in production for over a year in the v3 DSP models. To my knowledge we have not had a single one returned with a fault.
Thanks,
Andrew
