摘要 <p>PURPOSE:To prevent malfunction at recording from a device other than a player and to attain simultaneous recording from the player by operating a control signal by a voltage signal only when the player is selected by the mode changeover. CONSTITUTION:An M3 jack 11 provided to a player 4 and an M3 jack 22 provided to an amplifier 2 are connected and an M3 jack 12 provided to a cassette deck 1 and an M3 jack 23 provided to the amplifier 2 are connected. In selecting the player by a mode changeover switch 24, terminals 24b, 24c are connected and in selecting a device other than the player, e.g., a tuner, terminals 24a, 24b are connected. Then, a signal relating to the elevation/descending of a tone arm from a voltage signal generating circuit 14 of the player 4 is applied to a control circuit 16 of a cassette deck 1 only when the changeover switch 24 selects the player, and the simultaneous recording of the player 4 and the cassette deck 1 is attained.</p>
