MBA-120
HideAway™ Series Mono-block Amplifier
Most modern installations for digital signage, corporate boardroom audio systems, classroom audio systems, retail merchandising kiosks, and plenum rated commercial sound applications, etc. needs a compact and robust audio amplifier. The MBA-120™ is a very good fit for such applications. It offers 20 watts of clean power into speaker loads as low as 2 ohms, allowing the installer to connect
multiple speakers to the same amplifier. The amplifier has a 45dB gain, thus eliminating a need for external pre-amplifier when using modern audio sources such as computer sound card or portable CD players, MP3 players, satellite radio receivers, HD music servers, digital signage players, etc. This miniature yet powerful package delivers high performance quality at an affordable price. The unit
accepts a line level audio signal on a 3.5mm input jack and provides an amplified signal on a 5-way binding post speaker terminal. The advanced protection circuitry guards against system damage from overload, over-temperature or short circuit load. The unit operates from a regulated 12VDC high-efficiency switching power supply which is included in the package. The integrated flanges have mounting holes to fasten the amplifier to any surface.
