I'm enjoying this Nobsound passive preamp with the Volt at the moment. Not many days go by that I don't try something different.
The Nobsound has two outputs and one is pass through which means there's no volume control upstream of the Volt when using that output and I like that. The second output is active and is controlled by the preamp's volume pot which I use to handle the volume of the bucket sub's amps.
Yes the Nobsound connected by RCA line levels from it's active output will control your sub's volume.
The Nobsound works equally well with the APPJ/MW as does the Sain Smart.
So if this controls the volume/gain on my subs, where do I set my subs volume control at? Max????
