Description
The AVLELEC MA30 Sound Masking Amplifier is a compact, standalone mixer with an integrated 30W power amplifier, designed to deliver versatile sound amplification for a range of audio applications. Featuring four speaker output options—4 ohms, 8 ohms, 25V, and 70V—via convenient screw terminals, the MA30 is ideal for installations requiring reliable sound distribution, including in sound masking systems.
Powered by 120VAC 60Hz, the MA30 includes built-in protection with a rear circuit breaker and a separate circuit breaker for the rear receptacle, ensuring safe and secure operation. The front panel offers three input channels—MIC/TEL, PROGRAM, and AUX1—allowing for flexible connectivity. Adjustable bass and treble controls enable fine-tuning of the audio output to suit various environments. Visual indicators include a power active LED and an output level LED, making it easy to monitor the unit’s performance.
The MA30’s compact black box housing measures just 8″ x 3.5″ x 11″, perfect for installations where space is limited. Rack mounting brackets are available for easy integration into a professional audio setup. This mixer-amplifier combo is an excellent choice for boosting the output of our SMG-2 Sound Masking Generator, or for any situation requiring efficient, high-quality sound amplification
