The MA2120 Power Amplifier is a reliable and powerful solution for clear sound amplification in various professional settings. It’s ideal for applications like live events, conferences, and permanent installations, delivering consistent audio quality with impressive output power.
This amplifier delivers exceptional audio, providing up to 120 watts per channel in stereo mode. It ensures distortion-free sound, even at higher volumes, making it perfect for public address, background music, or professional sound reinforcement. Whether used in small or medium-sized venues, the MA2120 guarantees clean, powerful audio for any event.
The MA2120 includes built-in safety features to protect both the amplifier and connected equipment. It has thermal, overload, and short-circuit protection, which automatically reduces output or shuts down to avoid damage. This not only ensures safe operation but also extends the lifespan of the amplifier and speakers.
Designed for flexibility, the MA2120 supports both balanced XLR and unbalanced RCA inputs, allowing easy connection to a range of audio equipment like mixers, audio interfaces, and other devices. The amplifier also offers speaker outputs with varying impedance options, so it’s compatible with a wide range of speaker setups, whether for a small meeting room or a larger venue.
