Speaker Level and LFE Sub?

Velodyne SMS-1?

I called velodyne regarding their DD series subs a few days ago. Rob said that their subs do take speaker level but not at same time as LFE. The SRS looks like the same eq as in their dd subs and I can't find anything in the manual that says it can do this. Maybe I just need 2 subs.

Can I ask why? Is the NAD in a separate 2 channel system or are you using it as the front L/R amp in a combined system? If the former, you do not need simultaneous use of line and speaker level inputs. If the latter, the LFE/sub output of the processor will handle it all at line level.

Its a combined system. (NAD M2 for 2 channel via AES/EBU & Parasound P7 surround preamp outputing the .1 to the same sub and the left and right surround to NAD M2 via interconnect) So, technically I don't really need simultaneous use of line and speaker level inputs. However, if the manufacturer won't certify this particular use, I could destroy my amp with conflicting grounding. That is, i would have a connection coming from the NAD and different connection coming from a surround preamp. Also, I don't know how the sub would handle two inputs coming in at the same time. So, you are correct that I don't need to listen to line and speaker level at the same time, but its going to happen anyway when I am using the NAD M2 for my surround fronts and my preamp is sending LFE at the same time.

Yo Big D, or as we in Houston like to call Dallas, that little city in South Oklahoma, I am going to do the exact same thing that you are, that's how I discovered the Def Tech's could handle that.

I suggest you do as I did, and call the very nice folks at Def Tech and ask them about it. They were great to work with and described in detail how this would work, and said it would be no problem at all.

Good luck.
