SMGA-25 Sound MaskingGenerator/Amplifier
SMGA-25 Sound MaskingGenerator/Amplifier
Model SMGA-25 provides an analog noise signal along with an amplifier (25W into 70V or 8 ohms) for sound masking applications. The generator produces a pink noise output signal that is fed to masking speakers to mask ambient noise, allowing for more conversational privacy and improved productivity. Order sound masking speakers separately.
Features
• Noise Generator: Outputs include a Pre-EQ and a Post-EQ line level (~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 (25W maximum).
• Controls: Bass, mid, and treble controls allow for basic noise spectrum shaping without an external equalizer.
• 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 @2.5A output.
