How to Bridge TFM-4.0?

Post by seehear » Sun Jun 21, 2009 1:25 am

Hi, I have a TFM-4.0 that I want to use as a sub amp. It has a bridge button, but there are no indications as to which speaker wire should go where (or which input to use). Does anyone have a manual or experience bridging this amp? If so, please advise. I have owned this amp since new (it's number 18) and dont want to kill it now. I am currently using a Hafler 9270 that does a passable job as sub amp but runs too hot. My hope is the 4.0 will make more power and less heat.

Thanks in advance.

Welcome seehear. Take a channel from pre amp and feed it to both right and left inputs of the amp with a Y connection. Looking at the back of the amp. The left red speaker output is the positive and the right red speaker output is the negative. Push the mono button in.

Thanks, I am going down to rat shack to get a Y cable now. Will be bumping along by afternoon, I hope!

Happy Father's Day to all the daddies out there!

I thought that you needed only to put the source into the left channel?
Some cool Carver stuff!
