Thread title pretty much says it. I've found a couple threads that talk about it but I wanted to make sure before I order one.
Can I run a 2.1 system using the DC-1 as a pre amp without any problems? The only thing I've noticed is the lack of a trigger but I can live with that. How do I go about bass management? Planning to use passive speakers and probably something like a SB 2000.
Any help is appreciated.

Well you could send a feed (either split the RCA output or use XLR for mains and RCA to sub)to the sub. Then set the frequency control on the sub to a reasonable level.. say 100Hz. Now this isn't "bass management" in the true sense, but it gives a pleasing result nevertheless.

Hemster beat me to it.
Another option, if you sub supports it is to run the rca (or possibly but less likely xlr) to the sub then out from the sub to the speakers. You can then set the crossover on the sub.

I just run my sub so that it naturally crosses over with where my speakers bottom out. Works well for me.

What this option means is that your main speakers will run full range and your subwoofer is adjusted with its own crossover controls to fill in the gap. This will work. However, the USP-1 allows you to set a crossover and basically have your main speakers only handle the mids and the treble and leave the bass for the sub. That's the main difference. I personally feel that it will work pretty decently.
The DC-1 is clearer than your other options and also more balanced. You may give up a tiny bit of impact in your music but not much. A better matched option for the DC-1 would be the fantastic XSP-1 which is more resolving in my opinion in the frequency extremes than the USP-1. I hope to audition this combo hopefully soon when I get a chance!

Reading your signature/profile I assume this is for the "bedroom" system?
If I'm reading it correctly you currently use an ERC-1 to feed the USP-1 in that system hence the addition of the DC-1 is to utilise it's better DAC.
Since you already have an XSP-1 in the "living room" as well as the aforementioned USP-1 you have the ability to do back to back testing.
My view would be to get the DC-1 and use the 30 day trial period to do some detailed listening for yourself. Some people like the DAC direct to power amp set and some don't. I'm with garbulky, I much prefer the sound with a preamp in, plus their inbuilt ability to do analogue bass management.
I suspect you wil get a split decision relying on other people's opinion, hence it's really a question for your personal preference.
Cheers

Well you don't NEED an XSP-1 in the chain especially for a bedroom system. But testing may indeed be nice. What may be much easier is to simply try the DC-1 in your living room to one of the XSP-1 inputs and see if you notice a difference. If not - problem solved  I would try both DC-1 direct to amp (it's actually pretty good), and then try it with the USP-1 and see what you prefer. As for volume controls. You would only use one volume control. Leave your macbook volume maxed out always. Then decide which one you want to use as a volume controll the dc-1 or the USP-1 then max out the one you are not using as a volume control. However in the case of the USP-1, I wouldn't max it out, as you may get noise. I would probably get it near halfway as it gets LOUD fast. If you need to max out the DC-1 put it to zero not to a + number. Interestingly yo uhave two diffferent volume controls here. The DC-1 uses analog resistors tha are integrated on a single chip. The advantage is that you have very little channel imbalance with them. However it's a bunch of resistors on a chip. Not necessarily bad, but it's what it is. THe USP-1 uses a potentiometer which is more susceptible to channel imbalance. A different kind of volume control but more "traditional". You can decide which you prefer |

Now this isn't "bass management" in the true sense, but it gives a pleasing result nevertheless. Question: if you send a feed from the DC-1 RCA output to the sub, if the sub only has one RCA input, do you use only one of the channels, Y both together or is this only for LFE signal? |

Question: if you send a feed from the DC-1 RCA output to the sub, if the sub only has one RCA input, do you use only one of the channels, Y both together or is this only for LFE signal? First, this is not for LFE signal because the DC-1 doesn't have a LFE sub output. What we're talking about here is passing the full-range signal to the sub (just as it is to the main L/R speakers) and then having the sub crossover limit the low-end frequencies. Second, I would suggest summing the signal with a Y adapter if the sub only has one RCA input. That way you're sure not to miss out low-end on either channel. |

You can also use the high level inputs on sub ( if it has them)

^But be warned, depending on how high quality the sub's high level circuitry is, you may degrade the sound. Or it may be just fine. Just a warning.

Finally got my DC-1. Missed the 110/220V switch on the bottom and blew the fuse immediately!  Anyway went out to buy a fuse and now everything works. First time I can clearly hear the difference between two devices (Sonos Connect internal DAC vs DC1 and iPhone earbuds vs same earbuds on headphone output DC1). Getting excited to look for a good pair of headphones now! Love it! |

brandGlad to hear you are enjoying it! Have you tried comparing XSP-1 with USP-1?

brandGlad to hear you are enjoying it! Have you tried comparing XSP-1 with USP-1? No hehe I just got it today and I'm currently studying for my finals. I will test when I have some more time to switch things around and test it out. Will report back. |
