Much better than the cheap generic one I was using before. Using a meade distortion meter, I didnt see any distortion. And it even registered the signal, unlike the generic converter, which picked up extra noise. I recommend going with the gain knob. They make it easy to dismantle the assembly and flush mount it, mounted the knob to a spare accessory panel in my toyota.
Very easy to install, having the remote turn on feature made this the perfect line out converter along with the level controller knob. I would definitely recommend this LOC
