PINK AND WHITE NOISE GENERATORS

White noise is shaped and filtered to make Pink noise which is an essential tool for running many tests on sound systems. 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. Many people select pink noise in place of white noise since higher levels of white noise can burn out tweeters. The model GLPN, when time averaged, produces levels of plus or minus 1 dB making it an excellent standard for "FLAT" response. 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.

GLPN GLPN Pink Noise Generator PRODUCT DESCRIPTION: Pink Noise Generator providing continuous pink noise. Whenever the GLPN is connected to a system with Phantom Power, the LED on the back will light. If it does not light then phantom power is not present.

FREQUENCY RANGE: 20Hz - 20kHz
TYPICAL FLATNESS: 1dB 31Hz - 20kHz; +1/-2dB 25Hz
POWER REQUIREMENTS: 12Vdc - 48Vdc phantom power
SIZE (W x H x D); WEIGHT: 2.75" x .75"; 2 oz
CASE MATERIAL: Die cast body
