Thanks. Unfortunately the TL designation can be confusing and it does make a significant difference. I think Sandy should have given it a whole new model number.
At any rate, if no one has an owners manual, what I need to know is:
1) What is the internal crossover point for each of the 2 low level inputs? For the LFE I'd be willing to bet it's in the 80-90 hz range, but you never know. For the full range low level input, I wouldn't have the slightest idea.
2) Do I need to remove the "Low" speaker terminal jumpers from the high level inputs before using either of the low level inputs? I certainly don't want to fry anything. I'm sure replacement parts haven't been available for a long time.
