Wondering if anyone knows if the sub preout on a Denon 3808 has enough power to deliver signal to 4 subwoofer amplifiers or is there some type of line driver for home audio that would have to be used?:scratch: Thanks for any responses.:T

I suspect that you would not be able to get 4 subs to run to there full output off of one line feed. But really the only way to know for sure is to give it a try it wont hurt anything.

No worries of burning the preout up?
If they aren't getting full voltage is there anything that can be used to perk up the signal? Thanks.

One of these would boost the signal.

Sorry for what may be a silly question but how does that work and get the job done? All the reveiws talk about using it as a mixer for there computers?:scratch:
I'm tottally new to this using proamps in the home thing so i hope you'll forgive my ignorance and numerous questions. Thanks again.:T

simply plug the sub output of the receiver into the input 1 on the mixer (you will need to buy a 1/4" TS adapter to rca from them as well) and then plug the two tape outputs (left and right) into the subs inputs two subs on each output.

4 is a bit much to drive the subs with Y adapters, but some sub amps have pass throughs (line in, line out), so you can daisy-chain them.

Not sure if mine do, have to check. I'll be using 2 HPSA1000r amps and 2 Crown xls802 amps.:dontknow:

I have the hpsa 1000 standalone amp and it does not have a line out. :( Just stereo in and line in.

Not sure if the plate amps from the same company (with similar product numbers) have the line out.

Does that bump up the audio signal from the preout so you can run multiple amps without preout voltage drops and all 4 amps get the signal they need?:huh: Thanks.

Well I only have one sub but I would think you can split the signal coming out of the s-convert at least for 2 subs. 4 subs I don't know but I would still lean towards it working.

Maybe I'm mistaken, but I read somewhere (Can't remember), that using a Y cable from AVR to split the signal doesn't affect/degrade it.

Will you be using DIY subs????

When I started this hobby I had a Sony AVR with just one sub output, I connected a Velodyne sub, an Infinity sub and Buttkicker amp splitting the signal with "Y" cables; I didn't notice anything bad.

I think that as long as the pro-amp receives enough signal from AVR it will work fine, (just read the manual to see how much voltage do you need to get the most out of your pro-amp, in my case the Samson needs at least 1.24V(4dBu) to get full power, I'm not sure how much my Yamaha RXV2700 delivers on the sub pre-out) but they sound good.

EDIT: I just read the manual and Yamaha outputs 2.0V

I better brake out the holy bible of Denon and see what it says. Thanks for the insight.:T

Well looks like i'll have to call Denon tomorrow as i can't find the specifics on voltage.:hissyfit::scratch:
