Lowell Manufacturing Sound Masking Generator with 5W Amplifier

The SMGA-5A provides an analog noise signal along with an amplifier (5W into 70V or 8 ohm) for sound masking applications. The generator produces a pink noise output signal that is fed to sound masking speakers (ordered separately) to mask ambient noise, which allows for greater privacy in conversations and less distractions for improved productivity. Noise Generator Outputs include a Pre-EQ and a Post-EQ line level (Approx. 500mV) pink noise signal. The Pre-EQ output has a flat spectrum that can be used as the input to equalizers that feed power amplifiers for masking systems that require precise equalization. The Post-EQ output spectrum is adjusted by the bass, mid and treble controls and can be used for less demanding applications that utilize basic spectrum shaping. Amplifier Speaker line output is adjusted by bass, mid and treble controls. AUX Input Independent level control is provided to add paging or background music to the masking system. Outputs Include hi-Z line level, Pre-EQ and Post-EQ, 8ohm speaker and 70V speaker line (5W maximum). Controls Bass, mid and treble controls allow for basic noise spectrum shaping without an external equalizer. Chassis Steel chassis measures 12.2"W x 3.2"H x 6"D. Includes mounting brackets for rack, shelf, wall or under counter. Power Supply Universal input (100-240VAC) and 24 VDC at 2.5A output.
