Hello - good evening
I am interested in buying an emotiva BasX - A 100 amp, and I am wondering if the Output on the back of the Amp can be connected to a subwoofer, and if it is a variable OR fixed output. My plan is to take the outputs from the usb dac into the a-100, and the outputs from a-100 into a subwoofer. I am thinking the A-100 has fixed lineout connection and in that case I can only control the subs volume from the back of the subwoofer, and not by varying the volume on the a100, is my assumption correct?
thank you for your time
Harris

The manual states:
"This is a line level output that delivers a duplicate of the input signal."
So no, you would need to adjust the sub's volume separately. It would be nice if it either had a preamp out or the loop out was switchable between preamp and line level. That would make this beast the perfect budget amp for a bookshelf + subwoofer setup.

There may be another way. |

Maybe one could use a control freak and a cable splitter so it is connected to both the mini-x and the subwoofer?

The ideal solution would be to use a subwoofer that has its own crossover and level controls (ours and many others do).

Doesn't the loop out send a line level signal, though? How would the subwoofer's volume be adjusted via the amp?The ideal solution would be to use a subwoofer that has its own crossover and level controls (ours and many others do).

I have two mini 100's looped in this configuration receiving input from an apple airport express. Crank the volume on the mini 100 to 3pm (about 75%) and then use the volume on the phone or pc whatever you have connected |

Thank you for all the replies guys - yes I think the a-100 might not fit my needs (A-150 will be better), so this is my plan - also It seems that Control Freak is no longer for sale, it seems like an amazing product.
I will get a DAC with Volume Control - (output from the DAC into the Subwoofer - then from the subwoofer high pass to pre outs on the A-150)
this seems like the best solution. I wish Emotiva would really make an integrated amplifier like the parasound halo integrated with bass management for mains and subwoofer. I would be a great product for under 1.5K, no one else offers it yet besides parasound I think
thank you

However the bass management is fixed - no adjustment controls that i know of. The TA-100 (one box lower power amp) Or the PT-100 + A-300 (higher power amp) |

His best bet if he wants to use Emotivas offerings is the PT-100 feeding into his sub and then to a separate BasX amp. To save money I'd use the PT-100 fed into a Dayton APA-102 or similar Audiosource Amp. |

Using the output jacks on the A-100 is in fact variable from a preamp. The A-100 sends the same signal that is sent to it's input jacks from the source - usually a preamp. It can be used to send the audio signal to a sub - IF the sub has it's own variable crossover dial - which most do have.
OP - post all the audio gear you are using if you want a definitive answer.

If he's using the power-amp portion of the TA-100 then his main speakers will be fed a full range signal. The subwoofer outputs on the PT-100 and TA-100 are just mono-summed signals. Additionally, they have no bearing on the signal the speakers are fed. Whether through the power amp or RCA outs, no high-pass filters there. |

Sure he can feed his sub RCA from the Basx Pre and use that same TA-100 to power the speakers but that's pretty darn sub-optimal considering these preamps don't offer any bass management outside of a separate monosummed output. He would basically at the mercy of the crossover-dial of his subwoofer, and just hope that the crossover slope on the main speakers aligns with the rollof his speakers exhibit in his room. |

No bass management, I wasn't aware of that, I thought for sure the preamp had that, sort of crappy then especially considering the TA-100 is like $600 CAD up here. |

Thank you I am using a Schiit Modi DAC + Schiit SYS (SYS is just like control freak) this setup will be going INTO SVS NSD 12 subwooder - HIGH LEVEL OUTPUTS from the subwoofer will feed the Emotiva AMP - connected to SVS Ultra Bookshelf speakers Thank you all for your Input, but it seems that at my price point / budget - Bass management is out of the question - The only 2.1 channel preamps that will do Bass management Properly (Crossover for Mains, and for the Sub) are out of my budget right now. One is offered by Emotiva XSP 1 - 1200$, and the other one is Parasound p5 - 1100$. As someone suggested the TA-100 does have sub output, but it sends all frequencies to everything connected (Sub + mains) - maybe I should save a bit more and buy the XSP 1 + A -300. To me a properly setup system with correct crossover frequencies will sound a lot better compared to lets say just buying expensive speakers, and ignoring a quality preamp / amplifier thanks again |
