|   <newbie> sub output vs. pre-amp output | gszczyrb
Feb 21, 2002 5:42 PM | | I am about to put together my first home theater system. I'm a newbie, but at the same time, I'm not satisfied with the off the shelf packages, so I am putting together my own system. I have the speakers - Acoustic Research satelites and center channel. Still need to get a sub and receiver.
The receiver I want - Yamaha HTR-5450, also known as RX-V520 does not have pre-amp outputs, but it does have a subwoofer output. Isn't this essentially a mono pre-amp output?
I just want to make sure that the sub output is not an amplified output. Or if it is, I want to make sure this is not a problem if I buy a powered sub. So far I've been able to figure most stuff out, but this is confusing me.
Thanks,
Greg |

And the sound information fed to that output by the receiver differs depending upon the program selected.
I you set your front speakers as ¨small¨ , when playing CD the receiver will feed lo-freqs to the sub, relieving the small speakers from the stress caused by boom-boom sounds.
In this situation you can say that´s more or less a mono pre-amp output.
But when playing a DVD movie, subwoofer output feeds the so called LFE (low frequency effects), in short, the boom-bang, whaaams any action movie has plenty of.
If you chose ¨no sub¨ at your receiver´s menu setting, no earth shaking bass will be processed during movie reproduction.
Hope this helps.

Feb 23, 2002 12:39 PM | | pre amp outputs mean you can hook up more powerful amps to the receiver if you wanted to..The sub mono connection is a way to just plug in your sub..So you go buy a POWERED sub get a cable and plug it in and you're good to go..The amp does NOT power the sub..It's not a bad idea to buy a receiver with pre amp outputs in case you feel you need more power in the future..Then you just have to buy a new amp and your set..cool? |
