PURPOSE:To attain inputting of both analog and digital signals also the simultaneous monitoring for both signals with an inexpensive device, by using plural changeover switches and separating an analog signal route from a digital signal route. CONSTITUTION:When an analog signal is recorded, changeover switches 5 and 17 are connected to a terminal R together with changeover switches 18 and 16 connected to a terminal A, respectively. The analog signal supplied from an analog input terminal 1 is fed to an LPF13, and the output signal is outputted from an analog signal output terminal 11. At the same time, the output signal fed from an encoder 4 is recorded on a magnetic tape 7. When a digital signal is recorded, the switches 5 and 17 are connected to the terminal R together with switches 16 and 18 connected to terminals D and PD, respectively. If a digital signal is supplied to a digital input terminal 14 under such conditions, the output signal of the encoder 4 is recorded to the tape 7. Then the output of a D/A converter 9 is extracted to the terminal 11 via an LPF. |
