PURPOSE:To reproduce an input sound signal at recording with fidelity, by providing the 1st switch switching an output of an automatic level control means and that of a manual level adjusting means, and the 2nd switch switching an output of the switch and that of a noise reduction circuit. CONSTITUTION:Switches 13, 14 and 15 are interlockingly switched and two recording systems are constituted between an input terminal 1 and a recording head 5. The 1st recording system consists of an automatic level adjusting circuit (ALC)16, switches 13, 14, an amplifier 17, and a recording head 5, and the 2nd recording system comprises a manual recording level adjusting device 18, the switch 13, a compression circuit 19, the switch 14, the amplifier 17 and the recording head 5, an output of the switch 13 is connected to an output terminal 12 via an amplifier 20, allowing to monitor the ALC16 of the 1st recording system or the adjusting device 18 of the 2nd recording system. |
