Same Sub for HT & Music Question
Early B.
Posts: 7,900
I have a VMPS sub hooked up to my pre/pro on my HT system. I also want to hook it up to the other set of outputs on my CDP so I can use the sub for 2-channnel music (my preamp only has one set of outputs). Of course, the CDP and HT pre/pro will never be turned on at the same time.
Here's how I'd do it -- get a y-adapter and hook it up at the pre/pro, then run an RCA cable from the pre/pro to the CDP.
Will this hookup work?
Thanks.

Does the signal for your speakers go through a preamp? If so, then how would you match the signal to the speakers with the signal to the sub? Doesn't sound right to me...._________________________________________________

The signal starts at the CDP, so the sub would by-pass the pre and go direct to the source. In a previous 2-channel setup, I had a sub hooked directly to the CDP and it worked fine. The sub's crossover, volume, and other settings will allow me to dial it in. The configuration I described above is slightly more complex, but I wanna make sure I don't screw anything up before proceeding.
I'm not sure it's gonna sound good, but it may be worth a try. I had stereo subs at one point and I loved it. There's no room for them now, so I want to maximize what I already have, if possible.HT/2-channel Rig: Sony 50 LCD TV; Toshiba HD-A2 DVD player; Emotiva LMC-1 pre/pro; Rogue Audio M-120 monoblocks (modded); Placette RVC; Emotiva LPA-1 amp; Bada HD-22 tube CDP (modded); VMPS Tower II SE (fronts); DIY Clearwave Dynamic 4CC (center); Wharfedale Opus Tri-Surrounds (rear); and VMPS 215 sub

Not impossible to make it work....but every time you turn the preamp's volume up/down, you would have to adjust the sub's volume. A real PITA if you ask me

Not sure where you come up with these ideas, but this one’s great.
If you want to use the sub for both the HT and two channel while using the CDP analog output through the pre/pro, I would suggest a slightly different approach. As I can not find out the specifics about the sub plate amp you use, I will assume it has at least L+R line level inputs.
For the L+R signal path, insert a two channel active crossover between the pre/pro and power amp. The pre/pro output to the active crossover input. From the active crossover, the LP (low pass) goes to the MVPS 215 and the HP (high pass) goes to the Emotiva LPA-1.
From the SSP, the LFE goes to the VMPS 215.
If the sub plate amp only has L+R line level inputs, you will need an active crossover which will sum the LP output to one line level out. This would go to one of the sub plate amp line level inputs. The SSP LFE would go to the other sub plate amp line level input.
If the sub plate amp has L+R and LFE line level inputs, you do not require an active crossover which will sum the LP. The crossover L+R LP can go to the sub plate amp L+R inputs and the SSP LFE can go to the sub plate amp LFE input.
Disable the sub crossover over as this is not required anymore.
For two channel listening, the active crossover will direct the frequencies to the appropriate destination.
Set the front L+R speakers to LARGE or FULL or whatever it is called in your SSP. The remaining HT speakers would be set appropriately. The active crossover will direct the front L+R speaker frequencies to the appropriate destination.
If your sub plate amp has L+R inputs, L+R outputs AND a LFE input bypassing the plate amp crossover, you may not require an external active crossover. You would make the connections according to the active crossover directions using L+R and LFE inputs. The sub plate amp crossover would be used for the L+R channels. Once again, the dedicated sub plate amp LFE input MUST bypass the active crossover.
This works great. I have this implemented using a dbx active crossover. It works so well, I have a Bryston 10B Sub active crossover in transit to replace the dbx.
The most challenging aspect of this configuration is properly calibrating the system. If you can calibrate the system, I won’t see any posts from you stating the HT and two channel systems should be separate.
Good luck and have fun.

:eek:
No external crossover. I'm going to keep it simple or not do it. I'm pleased with the bass performance of my fronts right now, but I just wanna experiment to see what happens. It won't cost a dime. I think I have an extra RCA cable long enough to do the job.HT/2-channel Rig: Sony 50 LCD TV; Toshiba HD-A2 DVD player; Emotiva LMC-1 pre/pro; Rogue Audio M-120 monoblocks (modded); Placette RVC; Emotiva LPA-1 amp; Bada HD-22 tube CDP (modded); VMPS Tower II SE (fronts); DIY Clearwave Dynamic 4CC (center); Wharfedale Opus Tri-Surrounds (rear); and VMPS 215 sub

Does the sub's amp have an LFE input and L/R inputs?
If so, maybe you could use the LFE input from the pre/pro (do bass management in the pre/pro) and use L/R input input from the 2-ch source (using the sub's low pass filter to blend with the mains).
Also, instead of using the the CDP as the 2-ch source, you could split the 2-ch pre's output to feed the sub L/R and main amps, allowing the sub volume to track with the 2-ch pre's volume.5.1 and 2.0 ch Basement Media Room: Outlaw 975/Emotiva DC-1/Rotel RB-1582 MKII/Rotel RB-1552/Audiosource Amp 3/Polk LS90, CS400i, FX500i/Outlaw X-12, LFM-1/JVD DLA-HD250/Da-Lite 100" HCCV/Sony ES BDP/Sonos Connect.

Since you elegantly stated you dont understand, I drew a picture.
The Bryston 10B arrived. It is worth every penny I paid for it.
Looking forward to reading your experiment results.

Glad to hear the Bryston 10B has lived up to it's reputation. Maybe there's one down the road for my system?"2 Channel & 11.2 HT "Two Channel:Magnepan LRSSchiit Audio Freya S - SS preConsonance Ref 50 - Tube preParasound HALO A21+ 2 channel ampBluesound NODE 2i streameriFi NEO iDSD DAC Oppo BDP-93KEF KC62 sub Home Theater:Full blown 11.2 set up.
