SuBXeRo Posted December 21, 2010 Share Posted December 21, 2010 In my search i came aross NHT speakers in my sound and vision magazine. I proceeded to check out their website and found this http://www.nhthifi.com/s.nl/it.A/id.828/.f?sc=12&category=1334 a volume controller that works via rca or single signal wire in. This is great because its smaller and eliminates the absolute need for a preamp/pro. just wanted to share! Quote Link to comment Share on other sites More sharing options...
tube fanatic Posted December 22, 2010 Share Posted December 22, 2010 A person who is reasonably handy with a drill and soldering iron could build this device for less than $15. Their price of $160 seems a bit absurd to me. But, it's nice to see some interest in passive line stages again. They were extremely popular in the 80s.

Guest " " Posted December 22, 2010 Share Posted December 22, 2010 I think this gadget has op amps in it. Quote Link to comment Share on other sites More sharing options...
tube fanatic Posted December 22, 2010 Share Posted December 22, 2010 I just found these comments on it: http://news.softpedia.com/news/How-To-Not-Have-160-Any-Longer-NHT-PVC-PC-52970.shtml If it did have op-amps it would be even more reason to avoid it and go passive in my opinion.

SuBXeRo Posted December 23, 2010 Author Share Posted December 23, 2010 i consider myself handy but i would not want to try and take on a task of building one of these because my technical knowledge of how to properly do so is limited let alone it would not look good at all when done. Does anyone know of another unit that is cheaper and could replace this one? Quote Link to comment Share on other sites More sharing options...

Does anyone know of another unit that is cheaper and could replace this one? Tell me exactly how you want/need to use the device. Would only a single input suffice? I have a friend who may have something that he can loan you so you can test the concept of a passive line stage without incurring any expense.

dale_s Posted December 24, 2010 Share Posted December 24, 2010 I think this gadget has op amps in it. Really? Their user manual states that it has jensen transformers in it. Might be a quaility piece? Quote Link to comment Share on other sites More sharing options...
tube fanatic Posted December 24, 2010 Share Posted December 24, 2010 The transformers are in the pro unit only and are used for isolation between the ground of the source component and what follows after. The PC version does not have the transformers from what I can tell. In either case, both are simply passive line level attenuators. Another negative with this unit is that it doesn't allow for any kind of balance adjustment between the 2 channels. NHT makes a point of the tracking accuracy between the two channels, but that's a moot point since most recordings are not balanced, and neither are our ears.
