摘要： A control level displaying apparatus includes a remote control signal receiving circuit having a discriminating circuit for producing a sound volume up/down control signal and at least one up/down characteristic control signal relating to at least one other characteristic of a received information signal in response to a received remote control signal, a sound volume control generating circuit for producing a sound volume control voltage in response to the sound volume up/down control signal, a second control voltage generating circuit for producing at least one characteristic control voltage in response to the at least one up/down characteristic control signal, a sound volume control circuit for controlling the sound volume in response to the sound volume control voltage from the sound volume control generating circuit, a second control circuit for controlling the at least one other characteristic in response to the at least one characteristic control voltage from the second control generating circuit, a control level displaying circuit for displaying the level of one of the control voltages, a supply circuit for selectively supplying the sound volume control voltage or the at least one characteristic control voltage to the control level displaying circuit, and a switch control circuit for controlling the operation of the supply circuit in response to the at least one up/down characteristic control signal so as to supply the at least one characteristic control voltage to the control level displaying circuit when a remote control signal for the at least one other characteristic is received by the remote control signal receiving circuit.
