Abstract

PURPOSE:To prevent a recording mode from being set erroneously and to improve functionability and operability by detecting the frequency of an inputted low-pass transfer subcarrier, discriminating the kind of a loaded tape, and setting a central frequency in frequency modulation automatically based on those results. CONSTITUTION:In a damping mode, a high level is set when a chrominance subcarrier formed in a frequency detection circuit 21, for example, of 924kHz is detected, and a low level is set when the chrominance subcarrier of 685kHz is detected. The discrimination signal is supplied to the input terminal on one side of a NAND circuit 24 and the input terminal on the other side of an AND circuit 25. Also, a switch 5 turned ON and OFF corresponding to the kind of a tape cassette is connected to the input terminal on the other side of the NAND circuit 24, and a tape discrimination signal is supplied to it. Thereby, the ON/OFF control of transistors 18 and 19 are performed adequately, and the base voltage of a transistor 34 at the output stage of a pre-emphasis circuit 13 can be set at the optimum value regulated by variable resistors 15, 16, and 17.
