The Line Level Shifter’s primary function is to increase or decrease signal voltage back and forth between -10dBu and +4dBV (depending on which way you route through it). This device also breaks loop antenna that causes ground hum and buzz, as well as converting back and forth between balanced and unbalanced connections AND preventing the cable to act as an antenna for noise.

Simply place a channel of the Line Level Shifter® on the cable connections between the two mismatching pieces of equipment. Line Level Shifter® will not affect the quality of the audio, it will improve it. Used are 1/4″ smart jacks that accept any combination of unbalanced (TS) or unbalanced (TRS) plugs. This is passive device (no power required), in cold rolled steel housing, hand-soldered circuit boards and top quality components and hardware.
