Default pre-out vs rec-out ...same thing or not?

Could someone please comment on the differences between: (1)pre-out vs. (2) rec-out vs. (3) DAT rec-out ...for purposes of sending a signal to a powered subwoofer.

Are the signal levels approximately the same among these three different types of outputs? If so, are there other differences that I should be aware of?

Thanks!!!

Pre-out varies with the volume-setting and Rec-out doesn't.

Use Pre-out to feed the sub.

Pre-out is generally variable by the volume control. The others normally are fixed in level (sometimes adjustable). The exact levels vary somewhat from equipment to equipment from less than a volt to several volts RMS. Best to check in the manual or try it out.

Hi,
rec out is often at a higher source impedance.
You need to keep the recorder close to the amplifier.

Default OK

...makes sense now.

The reason I asked is that I have two integrated amps...only one of which has pre-outs...so that is the one I will use.

I am assuming it will be OK to use RCA "Y" to split the signal from the pre-outs. I need to feed the sub as well as the amplifier's main input.

Is using the "Y" the correct way to go here?

Thanks again....

That should be OK. If you can keep the amp one short as possible that would be better.

Does the amp use those heavy wire jumpers from the "Pre-Out" to the "Main-in" jacks?

Some amplifiers (Like my Sansui AU-7900) use a switch to seperate the two "halves" of the amp.. You can leave the switch in the "connected" position,and just run RCA cables from the "Pre-Out" jacks to the sub or whatever,without needing to fiddle with Y-cables and whatnot.

I absolutely *love* the Pre-out/Main-in feature...I don't think I'll ever own/build another integrated amp without it!

Yes it uses jumpers...no switch. It is an Akai AM-U55.

Thanks everyone for the advice!
