ABSTRACT:
An indicator is responsive to a gain control voltage applied to an amplifier for indicating the gain of the amplifier irrespective of amplitude of the signal being amplified. The amplifier may be an audio amplifier in a television receiver which also contains an electronic tuner tuned by a tuning voltage, in which case, the indicator may alternatively indicate the tuning voltage while a television channel is being preset and the gain of the audio amplifier at other times.
