If your sub has bass management, run a full range signal to it from the dc1. If it doesbt have bass management, pick up a minidsp. No need for a preproif you only want two channels and a sub.

Sent from my HTC6500LVW using proboards I'm running balanced from the DC-1 to the amps so the analog outs are available for the sub. I'll try that tonight. Thanks. |

Thanks. this WAS how i was going to do it, but the only roadblock...is I would have no way to get the sub out (for LFE) from the avr to the sub (it needs to go through the minidsp as well)...if only the minidsp came in a 4 in 4 out :/ |

What is the difference in these hookups? Besides the order they are hooked up of course. What's the effect on SQ and who is doing the processing? I want to keep my DC-1 but I also want to have the sub with my 2 channel music.
1. OPPO 95 to DC-1 -- DC-1 hooked directly to amps. Black and white, no sub.
2. OPPO to DC-1 -- DC-1 to UMC-200 7.1 -- UMC to amps. No sub with 7.1 direct so why even do this??
3. OPPO to DC-1 -- DC-1 to UMC analog -- UMC to amps. Wouldn't this negate the DC-1 and use the UMC dacs?
3. OPPO to UMC -- UMC to DC-1 -- DC-1 to amps. Could this work and could I use the sub this way?
Just confused with all this. I want to keep the DC-1 but I won't if I can't have the sub running also. I may be wrong but the moment you engage the subs or do anything other than a direct pass through (i.e. doing 2.0 to 7.1 expansion) you will be using the UMC-200's DAC or there will be some conversion taking place. For subs without digital processing you would be looking at an analog pre-amp. You could use the DC-1's analog input as a sort of pseudo HT bypass from the UMC-200. Then use the other set of DC-1 outputs to integrate your subwoofer if your subwoofer has the appropriate controls. |

If not, then we'll go to plan B. Either way, if I keep the DC-1, I'll have to switch some cables when I switch from music to movies, ie. DC-1 to UMC-200.  |

Option #1 is best but no sub. #2 is mute and #3 & 4 bring in more conversion or other dacs. I want to keep the DC-1 for music but I really like the sub too. The 80s push some bass but the sub really adds to it. DC-1 may be going back unfortunately!!  |

if you hook it through the minidsp..and switch cables...remember you would have to go back into the dsp and turn off the crossover...kind of a pain...so that is why i am just running 2 channel without sub for now..until I can afford a XSP-1 (not a priority at this point since my music sounds fantastic)

Like I mentioned, the analog inputs of the DC-1 allow the front stereo channels of the UMC-200 to be integrated sort of like a USP-1 though not quite. Then using the unused XLR outputs of the DC-1 hook it up to the subwoofer. Then you get the sub and integrate the UMC-200. I tried the DC-1 with the m80's. In my room it had a bit too much upper bass. But man the thing sounded GOOD. |

XLR out from DC-1 to sub 3. Analog outs from DC-1 to amps?? Not sure about this one. |

Like: Match the levels of the analog outs of the DC-1 to the UMC-200. I think there is a way to do that (fixed vs variable output?), I just don't know much about it. Also the tough bit would be you wouldn't be using the sub output on the UMC-200. But maybe setting it to 7.0 rather than 7.1 would do it. I'm not familiar with this. But yeah what you described is the basic idea. |

...I want to keep the DC-1 for music but I really like the sub too...DC-1 may be going back unfortunately!! May I suggest two alternatives (I'm sure these have been discussed before, but just in case...) 1. Use the balanced outputs of the DC-1 to feed the power amp, use the unbalanced outputs to feed the sub. Use the low-pass filter on the sub to bring it in under the "normal" roll-off frequency of the mains. OR 2. Use either an external crossover or an amplifier with its own built-in high pass filter. The "pro audio" world is full of both of these, and IMHO, they sound just fine. I'm currently running a Crown XSP-1500 amplifier with its own internal high pass filter. The sub's own low-pass filter is set to the same frequency, and I swear I can't hear the transition! If you otherwise LIKE the sound of the Stealth DC-1 (many do, and really, REALLY do), then I wouldn't send back a DAC that you like just because it doesn't have built-in bass management. There are other ways to skin that cat (metaphorically speaking - I like cats...). Cheers - Boomzilla |

NO, cgolf - DON'T y-cable the L&R analog outs. I think that that shorts the two channels, & I'm not sure that the output circuitry on the DC-1 likes that too much...
It may (and may not) cause the XLR outs to be mono as well...
On the other hand, I may be wrong here. Anybody KNOW?
Until you get confirmation, I wouldn't go trying that.
HELP guys - any harm in combining the two channels (unbalanced) while trying to run the stereo outs balanced?

Don't have a Y cable anyway. Thanks. |

Actually I think for now, I won't even do this. I'm not sure it's designed to feed separate speakers through the balanced and unbalanced outputs at the same time. Seems like it is set up more for either / or and not both.
This has become a pain and hassle. I'll just run the DC-1 without a sub.

I can confirm that it IS designed to feed both the unbalanced and balanced outputs simultaneously - I'm using mine that way. The R&L XLR outputs feed my power amp, the R&L RCAs feed my subwoofer (which has discreet inputs for R&L). Feel free to use both outputs simultaneously and without worry. |

So are you running both R & L unbalanced separately to your sub or just one of them. Yes unbalanced R output to the sub's R input & the DC-1's unbalanced L output to the sub's RCA L input. The XLRs go straight to the power amp inputs. Both (balanced and unbalanced) outputs are apparently controlled by the same volume control as both volumes track identically. |

UPDATE--XLRs are out to the amp and L unbalanced from the DC-1 runs to the sub in. I just played a couple of CDs from the OPPO. Sub is engaged a little and it sounds better than no sub. So for movies, I'll have to change the sub cable back to the UMC and make 2 changes on the back of the sub but it's worth it. I really do like the DC-1 and want to keep it.  Thanks everyone for your help and comments!!! |
