I just received my 340/170 Home Theater setup. At the same time, I ordered a Panasonic SA-XR57K receiver. I'd heard some good things about it and I was intrigued by the digital amps. I ordered it because it's been discontinued. I plan to set up sometimes in the future a small LCD in the den to augment the HT. No reason to use bulb time to watch SD TV! At worse, I could use the receiver for the den.
I didn't know when I ordered it that there's two main speaker connections, A and B. I also didn't know that the unit can be configured to bi-amp fronts! Although it doesn't say explicitly (the manual is written for the average consumer), it looks like there's some active EQ applied. They were very explicit about hooking the LF to the A amp and the HF to B, else it wouldn't sound right.
I'm not expecting miracles, but it will be nice to have a little headroom for the 340's. I'm going to try it tonight.
I do have a technical question. Am I correct in assuming the only connection between the high and low sides of the crossover are the external removable jumpers? Also, if I use two different amps in this instance to drive the high and low sides, what is the impedence presented to the amp? The Panny likes 8 ohms and won't be as happy with 4.
