PURPOSE:To make a mixing input terminal of a mixing audio signal input circuit and a mike amplifier unnecessary by constituting a device so that the output of a recording audio signal input circuit is connected to the input of a mixing audio signal amplifier circuit and the output of this amplifier circuit is connected to an audio signal output circuit through a changeover switch in the reproducing operation mode. CONSTITUTION:In the recording operation mode, a switch 32 is connected to a recording-side contact, and a switch 33 is connected to an F-side contact, and then, only a line amplifier output signal 22 to be recorded is inputted to a monitor output amplifier 10, and mike sounds are monitored by a sound output terminal 24. In the reproducing operation mode, a reproduced signal 25 detected by a sound head 13 is inputted to the amplifier 10 by connecting the switch 32 to a reproducing-side contact, and reproduced sounds are monitored. When the reproduced signal 25 and mike sounds are mixed, the switch is connected to an E-side contact. A mixing mike signal applied from a mike 1 outputs a mixing amplifier output mike signal 23, and this signal is mixed with the reproduced signal 25 and is inputted to the amplifier 10, and sounds where reproduced sounds and mixing mike sounds are mixed are monitored. |
