PURPOSE:To realize a multiple sound circuit possessing various functions via a sheet of the print substrate, by connecting plural number of terminal parts via the jumper line and then supplying the output of the demodulator circuit to the increment circuit after shaped at the additional circuit. CONSTITUTION:The circuit is incorporated into patterns 2-4; and terminal parts 10/18, 9/17, 28/22 and 27/21 are connected via jumper lines 33-36. And the output of demodulator circuit 2a is shaped by additional circuit 4a and then applied to amplifier circuit 3a. Then the circuit is incorporated into patterns 2-4, and connector pins are set up into through-holes 7, 8, 15 and 16 each for connection of VTR. Jumper lines 33 and 34 are connected among terminal parts 27, 21, 28 and 22 each, and thus the output of circuit 2a is recorded by VTR. Then this output is reproduced and then shaped through circuit 4a to be applied to amplifier 3a. In this way, a multiple sound circuit possessing various functions can be realized via a sheet of print substrate. |
