置。[Claims for Utility Model Registration] The system is configured to adjust the output level of the reproduction signal amplified by the reproduction amplifier for each arbitrary reproduction mode, and then supply it to the next-stage amplification line amplifier. In the device, there is one control terminal common to the first playback mode and the second playback mode, and two "H" and "L" signals from this control terminal.
a switching element that is ON/OFF controlled by different types of signals; a first control element connected between the reproducing amplifier and the amplifying line amplifier; and a switching element connected between the reproducing amplifier and the amplifying line amplifier; and a second control element connected through the switching element, and when the switching element is OFF, the first control element adjusts the output level corresponding to the first reproduction mode. and when the switching element is turned on, the second control element adjusts the output level corresponding to the second reproduction mode.
