ABSTRACT:
A two-four channel tape player having a single eight-track tape head or a pair of fixed position tape heads, each head having four pickups, and each pickup aligned with a track on the tape. The pickups connect to voltage controlled amplifiers which are controlled by logic circuitry. The logic circuitry is programmed to select either two channel or four channel program material and is further programmed to sequence to other tape programs in response to a sequence command. Further signal processing is accomplished in output matrixing circuitry which is also logic circuitry controlled.
