The PN3C from Gold Line has a fixed and calibrated output level of -26 dBV. Its low output impedance allows it to drive both high and low input impedances without going out of regulation. It has a regulated and filtered power supply which can be supplied by an external AC adapter or a 9V battery. A power status Led indicates when lit that the battery is supplying adequate power. The PN3C turns on when a 1/4 inch phone plug is inserted in the output jack. There are no external controls.

Pink noise provides equal energy per octave allowing the adjustment of equipment drive levels with constant Hz bandwidth analyzers such as Gold Line RTAs. The spectrum of pink noise approximates that of much music which makes it an excellent test signal for sound systems. With a good pink noise source the user can adjust equalization and speaker crossover points and balance systems. Pink noise is also useful for sound masking systems and to provide greater privacy. It has also been utilized to help employees with Tinnitus.
