Subwoofer Settings

You can set it up, get it going, be happy,

However, there are (not math) operational considerations, and as you have/will see, not everyone agrees.

Decisions for a sub for an AV system are different than the more critical use of sub(s) in a 2 way system like you are doing.

Would you like my unsolicited comments on subs?

Please, solicit.

u mentioned LFE input... are you working with a Rel sub?

if so, Rel provides an EXCELLENT owners manual... it spells out in clear prose detailed instructions on how to connect -- for example, where/when you can, you should use the HI LEVEL inputs rather than RCA - they specifically supply a cable with Neutrik connector for ths very purpose... for best sound quality

It's an SVS jjss. I've got it figured out. Thanks.

Found it. This is the explanation I was looking for.
" If you are using one subwoofer for the bass of both left and Right Channels, connect the Left and Right preamp Outputs for these channels to the corresponding Line In connections of the STA-400D. Normally the High Pass Outputs of the STA-400D will be connected to the Inputs of thepower amplifier for the main Left and Right speakers. Using the High Pass Outputs will send all frequencies above 80Hz with a -12 dB per octave slope to the power amplifier for your speakers.

The Low Pass filter control on the STA-400D should be adjusted to provide the best integration of your speakers with the subwoofer. If you are using two subwoofers (one for each channel), connect as above using one sub for the Left channel and one sub for the right channel."
