Lehle DC Filter

The Lehle DC Filter eliminates DC voltage from analog signals. Audio signals containing DC voltage cause ugly switching noise. Now, both line and high-impedance signals are cleaned — but with no loss of sound. The DC Filter is of full stereo type, and thus filters stereo — and, of course, mono — signals. This little aid can even process balanced signals. The Lehle DC Filter is a passive filter, so it needs no power supply.
