Abstract: PURPOSE:To take a test signal recorded/reproduced at the time of test mode as a sine wave and to reduce distortion of the test signal by recording a characteristic on a magnetic tape through a recording equalizer capable of changing over in accordance with the record of audio signal or test signal. CONSTITUTION:At the time of audio signal recording mode, a terminal 3c of a changeover switch 3 is connected to a terminal 3a and a switch 8 of the recording equalizer 4 is ON-controlled.
