Abstract: A storage bin for compact discs in their native crystal boxes has an open top to permit viewing of the labels through the edges of the boxes, a forward sloping front wall to enable the boxes to be flipped for viewing the faces of the boxes, a guide extending downwardly from the base of the box dimensioned to be slidably received between the side walls of a like box so that the boxes can be stacked and slid with respect to one another, and an integral extension of the base for supporting a handle and a label frame. An optional divider partitions the bin to store two rows of tape cassettes.

Abstract: A vocal signal removing device includes a member for connecting one of the left or right side positive output terminals of a stereophonic sound reproducing device, e.g., tape, compact disk, or phonograph player, to the corresponding left or right side positive input terminal of an amplifier, and a member for connecting the other positive output terminal of the reproducing device to the negative input terminal of the amplifier on the side opposite the side to which the one positive input terminal is connected. A switch may be provided for effecting alternative connections to provide full stereo sound or monophonic sound including the vocal signal.
