Splitting turntable signal


Hi, here's what I am trying to achieve, please let me know if this is feasible at all.

I have a Rotel RP900 and Rega arm turntable, which goes into a Parasound P-100 amplifier. After this amplifier I would like to split the signal so that it goes to two different amplifiers in separate rooms:

(1) can this be done and what kind of splitter would I need? Assuming that I would not need both systems to be on at the same time, should I look into a switch rather than a splitter?

(2) what are the maximum recommended lengths after the amplifier (assuming this split which should be roughly...-3 dB?) that I could run?

Thanks a lot for all the help!

The best way to do it is to go out of the tape outputs on the back of one of the amps into the aux input on the other one. Then you can play whatever is connected to the amp. The cable length should'nt be a problem. You can't really split the phono signal because it is too small.

Ok thanks guys, what about the option presented here first, run from the phono to the phono pre-amp and then to one of the receivers and then from the tape out of the first receiver run to the second receiver?

Now the issue is that I imagined the turntable sitting in between the two rooms where this would be, so now the question is would it work to run from one receiver to the other one a long(er) cable? Assume the following:

(a) recv 1 ---- 15 ft cable ---- turntable + preamp + splitter/switch ---- 20 ft cable ---- recv 2

versus

(b) turntable + preamp + splitter/switch ---- 15 ft cable ---- recv 1 ---- 35!!!! ft cable ---- recv 2

Wouldn't the long cable create a problem? I would go with this solution if it doesn't since it's cleaner and I don't have to load the preamp.

THANKS!

We use the tape outs to tie systems together lots of times. It works well. In addition all other sources will be sent to the other receiver also.
Oh that's great to hear, will definitely try this tape-out method first and see where it takes me.

So is it safe to assume that on most receivers the tape out will output whatever is currently on the system? That would be amazing (could transfer some MP3 songs playing into the other room/etc.)

THANKS!
Yes, they will output what's playing and if you happen to have a record out selector you can listen to something else in the other room.
