Wow missed this one! no wonder no response. Can a mod correct the Post Title?
UNIT IS AN F1320D
Anyone have that? Unit has no lf output. I'm sure the driver IC is bad but instead of removing it I'm just going to see if anyone has a print with the generic IC # on it. It's the flat pack on the bottom of the amp board. May be the same one used in Mackie Thump speakers. HF driver IC is ok. -
LF driver is an TDA8950TH 24 pin 300w ampComment

Lacking an actual schematic of the unit, if you suspect the output IC, consult the IC mfg's datasheet.

The TDA8950TH is a busy little chip amp.
Lots of timing, startup & mode pins that have to be correct.
Generally speaking, if you have signal going in to the input pins & nothing coming out, the IC is bad.
Also, you could check the output pins to see if they are plastered to any of the power rails, which would keep the IC in protect mode.Comment
