Most modern installations for digital signage, corporate boardroom audio systems, classroom audio systems, retail merchandizing kiosks, etc. need a compact and robust audio amplifier. The SAA-212™ is a very good fit for such applications. If offers 2x12 watts of clean power into speaker loads as low as 4 ohms, allowing the installer to connect multiple speakers to the same amplifier.The amplifier has a 39 dB gain, thus eliminating a need for external preamplifier when using modern audio sources such as computer sound card output, portable CD players, MP3 players, satellite radio receivers, HD music servers, Digital Signage players, etc.This miniature yet powerful package delivers high performance and quality at an affordable price. The unit accepts a line level stereo audio signal on a 3.5mm input jack and provides amplified signals on gold-plated 5-way binding post speaker terminals.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 installation surface.
