Lowell SMGA-5A

SMGA-5A: Sound Masking Generator w/5W Amplifier

Sound masking (SM) generator plus amplifier (5W into 70V or 8 ohm) provides analog noise signal for sound masking applications.

FEATURES

• 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.
• 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.
• Power Supply: Universal input (100–240VAC) and 24 VDC @2.5A output.
• Chassis:  Steel chassis measures 12.2″W x 3.2″H x 6″D. Includes mounting brackets for rack, shelf, wall, or under counter.

COMPLIANCE & CERTIFICATION

• Made in the U.S.A. with global components

A&E SPECIFICATIONS

• The sound masking (SM) generator plus amplifier shall be Lowell Model SMGA-5A. The generator shall produce an analog pink noise signal and have both Pre-EQ and Post-EQ hi-Z line level outputs. Generator controls shall include level, bass, mid, and treble. The amplifier shall provide up to 5W amplification to drive sound masking speakers (ordered separately), and feature outputs at 8ohm and 70V line. The amplifier shall have an independently controlled auxiliary hi-Z line level input to mix paging, music, or signaling with the masking system. The unit shall be housed in a steel chassis measuring 12.2″W x 1.5″H x 6″D. It shall include mounting brackets (for wall, shelf, rack or under counter use), and a power supply with universal input (100–240VAC) and 24VDC @ 2.5A output.
