ABSTRACT:
A receiver having a tuner for tuning to a desired broadcast station and connected with a detector through which a demodulated signal is supplied as an input signal to a function selector which receives at least one other input signal from another source thereof and which selects either the demodulated signal or the other input signal as the output signal therefrom, a tuning control for selecting the broadcast frequency to which the tuner is adjusted and a volume control for adjusting the volume of the output signal from the function selector; is provided with a common display device, desirably constituted by a row of bar-type display elements, which selectively displays either the broadcast frequency, when the function selector selects the demodulated input signal, or the volume level when the function selector selects the other input signal or when the volume control effects a change in the volume level.
