Sound Masking Generator with Amplifier
Generator produces digital signal (pink noise) for masking systems that use a separate amplifier to drive the speakers. The signal is fed to the masking speakers to produce random low-level background noise that masks ambient noise and aids conversational privacy
• Generator produces pink noise (equal energy/octave) signal that is fed to speakers (ordered separately) to produce characteristic wind sound that masks ambient noise, creating conversational privacy. Controls include output level and adjustable low pass filter to shape frequencies at 9dB per octave with roll off at 300Hz.
• Amplifier (5W into 70V, 25V or 8ohm) includes auxiliary Hi-Z input for a paging, music or signaling source. Controls include level adjustment for auxiliary input signal and master level plus individual controls for shaping bass, midrange and treble frequencies.
• UL Listed power supply, input 100-240VAC, output 24VDC 500mA, 6 ft. cord and 4 plug adaptors.
• Chassis: 19 in. x 4 in. x 1.75 in.
