Lowell SMGA-25 Sound Masking Generator with 25W Amplifier

The Lowell SMGA-25 is a sound masking generator with a 25-watt amplifier that produces analog pink noise signal with pre- and post-EQ line levels. The amplifier output is 8 ohm or 70V. Bass, mid, and treble controls allow for basic noise shaping without an external equalizer. Auxiliary input level control allows you to add paging or background music to the masking system. Includes power supply and mounting brackets for rack, shelf, wall, or under counter use.

• Noise Generator: Pre-EQ and Post-EQ line level (~500mV) pink noise signal output. Pre-EQ output has flat spectrum that can be used as the input to equalizers that feed power amplifiers for masking systems that require precise equalization. Post-EQ output spectrum is adjusted by 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
• Power supply with universal input (100-240VAC) and 24VDC @ 2.5A output
• Chassis: 12.2" x 3.2" x 6" (plus rackmount brackets)
