My TV doesn't have audio outputs with adjustable volume so I bought this converter to bypass my TV's (horrible) internal speakers. I unplugged the TV speakers and connected the speaker wires to this line level converter. I then connected some good sounding USB powered computer speakers to the converter. The instructions say to set the source volume to 2/3, then turn the transducer controls clockwise to increase the level as needed. So I started with the pots counterclockwise. It initially sounded horribly distorted no matter what combination I tried on my TV and speaker volume controls. What worked for me in the end was the following: I turned the converter's potentiometers FULLY CLOCKWISE (maybe mine were set backwards?) and turned the speaker's volume knob all the way up. My TV's volume control stays in a very low range (8 for quiet listening and 15 for loud listening out of 100) but the sound is clear. I don't know why it worked that way for me, but it worked. Any other combination of the three levels will result in heavy distortion. In short, if you're having trouble, don't give up until you've tried all the level combinations.
