How do you add remote control to a preamp, here's how.


I purchased a new passive preamp on ebay (made in China) for little over a hundred dollars and.It looks very well built. There is absolutely no gain from input to output. The only thing in the signal path is an Alps volume pot and it is remote controlled. It has four quality inputs and one pair of outputs. I connected my sources to the passive preamp inputs and the pair of outputs to one of the inputs of the non remote preamp. Adjusted the volume halfway on the non-remote preamp. Wella, the remote now controls the volume and input selection via the passive preamp and it sounds marvelous.

ozzy62, I had a passing thought of hooking up the passive preamp directly to my amp and see what happens. I'm going ahead and do that and I will report back on the results. Hopefully there will be enough gain to satisfy me. I have some doubts though considering it is a CJ solid state amp and their matching preamps have a higher gain to drive it.

I could not agree more.  The Placette uses Vishay resistors with very tight tolerances to control volume and I have found it to be sonically invisible in my system.  A bit pricey but a worthwhile investment in my opinion.  Since the entire signal runs through it, it is not a place to go on the cheap !

I don't think the Schiit Saga passive can be beat for transparency...looks like they ditched the tube with the latest model.

With the relay stepped ladder volume control, you get perfect channel matching and no noise or distortion. It's as transparent as an RCA cable :-)  

The points above are well taken to get a better passive but I wanted to try this route to make sure this will basically work for me and with the excellent recommendations above I'm going to look into a better passive. But I will need at least three inputs and of course a remote.

Another feature of the Schiit Kara is the output impedance is the same in active and passive modes.
