ABSTRACT:
A level indicating system adapted to provide an indication of the peak-level or the volume unit level of an input signal. The system is comprised of an amplifier to receive the signal; a first changeable time constant circuit; a second changeable time constant circuit coupled to the first time constant circuit; an indicator connected to the second time constant circuit; and a control circuit for changing the respective time constants of the first and second time constant circuits. The indicator selectively provides an indication of the peak-level of the signal or the volume unit of the signal depending upon the particular time constants of the time constant circuit.
