So the HT Bypass allows you to completely bypass the USP-1? What would the setup look like (BluRay -> USP-1 -> UMC-1 -> UPA-7?) Does this mean I could run just two channels of audio (plus a sub) when I want to listen to music, and bypass the USP-1 and process from a UMC-1 when I want to watch a movie?
The part I'm hanging up on is if you're bypassing the USP-1 into a UMC-1, is there a way to shut off any DSPs? This is my biggest hang-up with my Marantz. I like to listen to music but I always feel like the Marantz is processing the stream, and I think they all sound like garbage (except for M.Ch Stereo, but it still feels like processing is happening.)
Let me know if this belongs in stupid questions. I guess the short of my question is, can you use a USP-1 in conjunction with a UMC-1 and have the best of both worlds (2 channel audio & 7 channel audio)?

Works the other way. 2ch sources to USP, outputs on the USP go direct to the amp (and sub). L, R & Sub outputs on the UMC go to the HT inputs on the USP.

Hopefully 1 picture is worth 1000 words: Thanks for this, it certainly speaks volumes (pun intended!) ;D Before someone asks... the top option shows HT usage and the bottom shows 2-channel usage. Currently I have 2 subs, 1 fed from the RCA sub out and the other from the XLR sub out on the UMC-1. I'm still trying to figure out how I can do this with the USP-1 without splitting the signal with Y splitter. Maybe I can't and a Y splitter will be fine. |

That makes perfect sense. Thank you for the diagrams. Does the USP-1 not have it's own DAC? Just curious. I guess I could look at a spec sheet....

Just a quick note. In the diagrams we have connections for R, L, and C indicated going from the USP to the UPA. There is no center channel connection between these 2 components.
The correct C connection is shown going from the UMC to the UPA.
I like the diagram, as this is a confusing topic. Especially when you're huddled down behind your rack with fistful of wires.

Thanks, just a drawing mistake - now fixed in linked drawing! |

No, the USP-1 is a pure analog 2 channel preamp with HT bypass. No digital circuitry whatsoever. Even the bass management (bypassed in the HT mode) is performed in the analog domain. Currently I have 2 subs, 1 fed from the RCA sub out and the other from the XLR sub out on the UMC-1. I'm still trying to figure out how I can do this with the USP-1 without splitting the signal with Y splitter. Maybe I can't and a Y splitter will be fine. Both the balanced and unbalanced sub outs of the USP-1 are live. Both can be used concurrently (just like the UMC-1). Otherwise, there is plenty of voltage on the unbalanced output where a good quality splitter can drive two subs easily (which is what I do). One unbalanced RCA cable from the sub out of the UMC-1 to the sub input of the USP-1 takes care of the connection between the two devices. |

Fantastic description and explanations. Thank you for clearing this up for me (I think). What this really boils down to is, I need more money. On the upside, I don't need that much more money and the solution I've been longing for is within reach. Anyone wanna buy a Marantz SR7001?  |

The powers that be at Emotiva, way back when, stated that even a single sub output (RCA, for example) have enough power to split an supply up to 4 subs. Just FYI. |

Hopefully 1 picture is worth 1000 words: so do u still need to powerup the USP-1 unit if your are watching movies in the HT mode? |

Yes, you do. thanks for the response Doc.. what is the rational for "HT by-pass" if you still need to powerup the pre-amp (USP-1)? Sorry for the noob question... My thought was that a HT by-pass mode is enabled when the pre-amp is in the OFF mode (power down) and ON when the pre-amp is power up. Then again, I was wrong... |

My thought was that a HT by-pass mode is enabled when the pre-amp is in the OFF mode (power down) and ON when the pre-amp is power up. Then again, I was wrong... The fact that the USP-1 has to be powered up for use of the HT Bypass is the way the USP-1 was designed. I have a Parasound 2100 and it does not need to be powered up to use my HT system. I hope Emotiva has changed this on the XPS-1 and I have a feeling they did  . I just see no reason for a preamp with HT Bypass to have to be powered up just to send a bypass signal through it. Bill |

there is no doubt in my mind that i would go for this setup if the USP-1 allowed me to run my mains at full range while in HT Bypass mode. unfortunately it doesn't so I won't. and the XSP-1 is just a little too expensive for me. Especially when the USP-1 is perfect in all aspects except that one. pity.

Especially when the USP-1 is perfect in all aspects except that one. pity. One thing to consider is that the LP/HP filters have a range of 50Hz to 250Hz using a 12dB per octave slope. Depending upon the "honest" capabilities of your mains, you may be at (or pretty close to) "full range". Just food for thought..... |
