Hi all, Just ordered the a100MiniX amp. i was considering a Topping 80 watt per channel tripth, but decided on the a100. I was told that the audio outputs are fixed on the back, and do not vary with the front volume control. I was hoping to use them to drive my sub. I am using a Dayton powered sub which has line level inputs plus speaker level input. Is there anyone here driving these subs with this amp? Just wondering how much the sound gets effected using this technique? Here is the sub. www.parts-express.com/dayton-audio-sub-1000-10-100-watt-powered-subwoofer--300-628. Does the fan ever intrude on the listening? I'll be using my iMacs headphone output to drive the amp. Someday down the line, I'll invest in a DAC,. this is just my desktop system. I have been running an RSP-2 preamp for about 6 years now with no issues. Hope this amp is just as reliable. is it robust enough to leave it powered on all he time? Anyother info on this thing would be great! Should receive mine this Friday. Attached a 3D rendering I did of my RSP-2 several years ago. Thanks.  |

Not really on topic but man do I wish they had kept this look. I like the silver buttons and volume knob SO much better than the all black Gen 2 look. Gen 2 doesn't look bad, this just looks so much better. Emotiva used to "look" high end and have it's own distinction among peers. Now it looks boring in comparison, and looks a lot more like plain jane receivers made by everyone else. Of course it's just my opinion and we all know what that means.  |

View AttachmentHi tony3d - Your Mini-X is the second best value in the whole Emotiva line in my opinion (the best is their XPA-2 power amp). To drive the sub the way you want, you'll need to let your iMac control the volume to both the Mini-X and the sub simultaneously. A "Y-splitter" will be needed. This isn't ideal because the iMac uses a digital volume control, and the lower you turn the volume, the more sound quality you lose. Because the RCA outputs on the back of the Mini-X do not go through the volume pot on the front, you can't control volume at the amp. A better solution might be to either use an Emotiva "Control Freak" passive volume control on the output of your iMac or else to use an external DAC (such as Audioquest's Dragonfly or Emotiva's "Ego") to both convert digital files to analog AND to control the volume. If you can afford it, I recommend the external DAC because the iMac's are merely "computer quality" and you won't hear your music at its best. Behringer also makes some very inexpensive yet "better than the iMac" DACs. The Mini-X fan was never audible to me. Boomzilla |

Not quite sure what this thing does. It's not a Dac right? |

youre using driving a lot here but i dont think its being used correctly. You want to feed a single from your mac to the a100 and then using the premap outs on the a100, you want to feed a signal to the sub. If this is correct, i can chime in. I tried this the other day thinking that the outputs were variable and they are not which makes it useless to connect a subwoofer to them since the subs volume will never change.
It makes sense of they designed them amp to be daisy changed in multiple rooms but for a 2.1 or even a 2.2 setup, that lack of control sucks

Not quite sure what this thing does. It's not a Dac right? It's definitely a DAC. It will out class the Mac's internal DAC. |

just send a signal from your mac-dac to the a-100 and connect your power speaker wires from the a-100 to the sub and then the sub to your speakers and use the subs on board crossover (if you want) and be done with it. The a100 isn't going to power the sub at all.

So am I correct that you will not be using the RSP-2? If that's the case just control the volume using your mac and do as sub zero says. However be warned if you accidentally have your mac volume set at full without knowing it then you will be pushing very loud volumes to your speakers and sub (maximum volume). If you want to still use the RSP-2 then imo that will be better. You won't need to use the mac to control the volume then. You'll use the RSP-2 which is a significantly BETTER preamplifier. Here's how. Use the Behringer UCA 202 (or use your mac output - works the same) and output the signal from the uca 202 or the mac to the RSP-2. The RSP -2 has two outputs. THIS IS WHERE YOU WILL CONTROL THE VOLUME. If your subwoofer has XLR inputs: use the XLR output to connect directly to the sub. Connect the RCA out[uts from the RSP-2 to the mini-x. Lastly use the subwoofer volume knob to adjust the volume so that the bass isn't too heavy or too little. It should be balanced volume between sub and speakers. Okay? If your sub does NOT have XLR inputs. hen purcase two RCA splitter cables Two of This: www.amazon.com/Hosa-YRA-104-Male-Female-Cable/dp/B000068O4Y/ref=sr_1_2?s=electronics&ie=UTF8&qid=1438729926&sr=1-2&keywords=RCA+splitter+cable This makes your RCA signal become two RCA signals. One for the sub, the other for the mini-x. With me. So one pair goes from the RSP-1 to the mini-x. The other goes from the RSP-1 to the sub. The reason you want to use the RSP-1 is so you don't have to control the volume from the Mac. THe reason you want to use the Behringer UCA 202 is because it sounds better than the mac. Remember garbage in, garbage out. Your Mac's DAC is a very cheap cheap unit. Though it works, you can realise sound improvements with the UCA 202. Whew, hope all that made sense. |

1. I don't think that you need a Y cable, you can use the line outs on the mini-x to the sub
2. If you could swing it, you could also look at the little ego. It has an analog volume control and is likely to sound quite good.
