Subwoofer & pre amp

Semi,

Im going to use the setup on the link with a fathom and my amp.

Use the Y connector and stop fretting. If it doesn't sound good, *then* you can start to explore other options. It'll cost you only $10 or so to find out...

Dear Semi: Dear Semi: ++++++ " what about variable? my pre amp has RCA line out which has fixed output, can that be used? " +++++

this is what you posted and that is your solution, you don't need to do anything else.

My vote for Velodyne was just in case you want to change to other sub alternative but like I told you you don't need to do nothing.

Regards and enjoy the music.

I am leaning toward building a voltage divider per Perrew's link simply because it will not alter or degrade my pre amp sound. adding a Y-splitter will change the sound for sure, I contacted Purist Audio and a pair of Y-splitters cost $300! not exactly pocket change for something I am not 100% sure will work for me.

like Stanwal said, Y-splitter will not introduce cross talk. however, it will change output impedance when I have both output hookup.

Dear Semi: Maybe I'm loosing something: you say that your F-113 has a variable/fixed gain control and that your preamp has a variable line out gain ( the normal one that goes to the main amplifier ) and a RCA fixed line out.

Why then are you looking for the " divider " when you already have what you need?:

in one " side " you have the normal output to your amplifier and in the other " side " you have that preamp fixed line out that can/could goes to the F-113 with the advantage that this fixed line out is a more " clean " signal due that does not has to pass through the volume/attenuator in the preamp like the signal that goes to the amplifier.

Now, is this what you are looking for? or like I say: I'm missing on the whole subject. Coul you tell me?, I appreciate that.

Thank you in advance.

Regards and enjoy the music.
