The success of the tiny little UAM4 stereo amplifier was incredible, but there
were a lot of requests for a complete system built around its technology. These
requests seemed like a great idea, so here it is, the UAM4SYS!
The amplifer is based on a single SMT device that runs in class D, which means it’s highly efficient and produces very little heat! Your
power goes into the audio output, not heat on a heatsink! The results, 21 watts per channel of stereo or 42 watts total or mono audio
power! All cool running without the need of heatsinks or ventilation requirements! Easy-to-use board jumpers offer selectable gain of
+22dB, +25dB, + 29.5dB or +36dB to match your input levels. Board jumpers also enable protection and shutdown options as well as
stereo/mono/bridge mode. The amplifier also features built-in click and pop suppression to protect not only your ears and sanity, but
your speakers and equipment! Line outputs are selectable pre or post processing and the headphone circuit gives you 64 steps of audio
level and stores your last setting! Construction is through-hole for easy assembly, other than the SMT devices which are pre-installed.
Runs on 28VDC for full rated output but runs well on 12VD for mobile applications! Visit www.ramseykits.com for full details and specs.
