I just purchased new speakers and want to use the L/R as full range with no sub when listening to stereo, and use the sub only for multi channel. I have the USP-1 and a UMC-1. Can you all tell me if I am thinking correctly about this? What I plan on doing is: Set the UMC-1 for the fronts to "small" and set a crossover point, somewhere between 60-80. The output for the L/R would go to the USP-1 input. The sub output from the UMC-1 would go directly to the subwoofer and bypass the USP-1. I would use the "full range" outputs from the USP-1 for the L/R speakers. I assume that if I play an analog source such as a CD connected to the USP-1, that the signal will go full range to my front speakers and it will not be affected by the high pass filter since the speaker output is connected to the full range, not the bass management jacks. Meanwhile, the L/R signal coming from the UMC-1 will be passed through to the full range output jacks of the USP-1 when the "HT Bypass" button is pressed on the front panel of the UPS-1. The signal coming from the UMC-1 will already have gone through its high pass filter and signals below the cutoff frequency will have already been removed. So what passes from the UMC-1 through the USP-1 to the amp for the L/R channels will be filtered. But what goes from sources plugged into the analog inputs of the USP-1 like the CD or Aux inputs will be passed full range to the amp. Therefore, it seems to me that I can use my front speakers full range when playing stereo analog sources, but when the HT bypass is engaged, I will be using the UMC-1's bass management system and the low and high pass filters will be in effect. Am I thinking correctly on this?  Thanks! |

Hey, neighbor (located not to far from you)
Unfortunately (if I understand you correctly) the HT bypass does not function on the full range inputs. So playing thru source connected to umc in ht bypass will not produce any audio signal.
Only source to usp-1 will...

Hey guys, just want to clear things up further, as I think jazzinfluenced got his reponse worded incorectly. What I believe your trying to say is: the HT bypass input does not work on the full-range outputs... Which is 100% correct, and I'm hoping this will change on the XSP-1. So, Monhumonku,... unfortunatley (If I understand correcty too) ...your method will not work. I'd hold out to see how the XSP-1 can be configured, if like me you want the option to use full range and/or bass-managenent in all inputs, including HT bypass...  |

I just purchased new speakers and want to use the L/R as full range with no sub when listening to stereo, and use the sub only for multi channel. I have the USP-1 and a UMC-1. Can you all tell me if I am thinking correctly about this? Sorry, I don't own either the USP-1 or the UMC-1 (so I probably should keep my mouth shut). But I will comment on where I believe your thinking is not correct. That is by running the OMD-15's full range in the first place when you have an excellent HSU sub (I know this is a hot subject for debate but I just couldn't resist getting my 2 cents in ;D). Please understand that I'm not trying to be negative about the OMD-15's. Everything I've read indicates they are an excellent speaker. However, I'm a firm believer that the HSU sub will outperform the OMD-15's in the 80Hz area and down for a number of reasons. First of all I'm a little skeptical of the OMD-15's specification of 33Hz at -3dB's especially for a 35lb tower with only a 5.5" woofer. (finally the HT Mag site is up and I see they tested it at -3dB's at 37Hz, that is actually impressive for this size speaker). Playing the bass (80Hz and lower) thru two towers can create both phase and room mode problems with the limitation of not being able to move them for the best bass reproduction below 80Hz. The sub can be moved to the best location for performance while keeping the 80Hz and lower frequencies omnidirectional. This also transfers the bass amplification to the dedicated amp in the HSU. You should experience flatter and lower distorted response in the lower bass thru the HSU. Your main amp will run with less sweat. I once had two full range towers that weighed in at 85lbs each, (Speakerlab 7's) that included a 10' woofer and 12" superwoofer in a tall cabinet. The drivers and crossovers were of excellent quality. I also owned a Klipsch 12" sub with passive radiator. I hooked up the system as 2 channel with only the two tower as full range. I played a Telarc copy of 1812 and used a RS meter on a tripod to test the output during the canon blast at fairly loud levels. I measured a level of 96dB's. Without changing anything except crossing over to the subs at 80Hz I play the cut again. Note that I did not set the gain on the sub too high as many folks do. It was set so that one was never aware of the sub as an individual source. This time the same exact portion measured 106dB's! This indicated to me in my case that a good sub can significantly outperform a good full range tower below the crossover point I only suggest that before your final setup for 2 channel stereo you do an A/B test comparing the frequency response output from 80Hz and down with the OMD's as full range and then with the HSU sub with a crossover at 80Hz. Set a reference level from about 100-200 to compare the test frequencies from 80 down to 30Hz or so. Remember some of the newer high end CD's have some quite low bass. I enjoy organ music but that is an exception. See how the levels compare on A and B as you drop down every 5 or 10 Hz from 80Hz and down. Do this test at average volume and also high volumes to see if the OMD-15's can keep up with the HSU sub in this range (I doubt it). Please have a 5-10 page report ready after you have conducted this test. That is all. Forum, dismissed! |

Well you know what, you guys were right - there's no pass through when you have the speakers in the full-range output of the USP-1! I remember there was a complaint thread or two or three about this when the USP-1 was first released and I kept up with it so I should have remembered this before even starting this thread in the first place. But (1) I couldn't remember exactly what the problem was and (2) I was too lazy to go back and read it. ;D I kept thinking you could still use the HT pass through on full range, but just couldn't use the bass management section. Not so.. you can't use the bass management or the front speakers if you have them connected to the full range jacks. Oh well, I guess I will just have to switch the jacks if I want to listen to them in full range. Actually, Chuckie is probably right - I should just use the sub since that's what it is there for.  |

Playing the bass (80Hz and lower) thru two towers can create both phase and room mode problems with the limitation of not being able to move them for the best bass reproduction below 80Hz. The sub can be moved to the best location for performance while keeping the 80Hz and lower frequencies omnidirectional. +100!!! ...In recent weeks I have gone from running pure-direct full-range mode on my Marantz SR6003 to 'Stereo' mode which allows me to apply EQ and some bass management. Unfortunatley the 'Stereo' mode forces the fronts to full-range, so cant actually cut them off below a certain frequency, it just adds in the sub below the set frequency. So what I did was EQ the 63Hz freq range for the fronts down about -3dB to minimise the output of the fronts below that frequency... but that's all Marantz specific fudging that you guys prob wont care about... ...The reason I did this was, the acoustics in my room created a huge build-up of bass in the back left corner, which came from the front right tower, which excited the bass below 65Hz in the front right corner of the room. This caused the sound to always feel very left weighted no matter what I tried... until I handed bass duties over to the sub.... Now it sounds great, and actually improved the over-all image and clarity immensly. So, now I would love a USP or XSP-1, so I can have both proper bass management, and a pure signal path... I'm leaning toward the XSP with it's suggested dual-differetial audio path, to compliment my two UPA-1's... And it would be nice to have a full-range option on HT-bypass, cos I know I'll wanna keep experimenting some more ;D` |

Opps...your right, Kiwi. I stand corrected...thx!
I was also waiting for the xps but could not wait any longer and purchased the usp first day it went on sale...will keep it in the bedroom. When the xps comes (fullrange pass-thru and disabling the lites, hopefully?)... living room it goes : b

Give your brain the nutrients it needs with FOCUSfactor, America's #1 brain health supplement. If you feel like this: Maybe you should try this: I don't get it... so if I feel like Hemster, I should take those pills??? ;D Nah, them pills do me no good.. trust me, I use them daily. I crush them and make a paste and then........ (TMI.. removed by moderator)ah crap... was I supposed to swallow them? |

I'm not trying to go against using a sub for stereo listening. But can't you just hook up the L/R channels from the UMC-1 into an aux input on the USP-1, rather than to the HT Bypass input?

Yep, but you'd have two volumes to control, UMC-1 and USP-1, the HT-bypass input bypasses the USP-1 volume control and just passes the signal directly out. You'd also not be able to pass your sub through the USP-1 if you wanted bass management for stereo listening... The HT-bypass input is there for a special reason Shane |

One good thing (not that all conditions make this a good thing) is that if you run a 2 channel kit on the full range outputs and your HT kit on the 2.1 outputs then is a good thing... if you only have one setup then YMMV
