The IMP100DL has a unique adjustable design which allows it to be used as an impedance matching stereo volume control when 2x, 4x, or 8x switch positions are selected, or as a standard stereo non-impedance matching volume control when 1x switch positions are selected (Note: 1x positions are for use with impedance matching speaker selector or other impedance matching device).
