Plenum Rated amplifiers

Plenum rated amplifiers are the ideal solution for installing sound systems in small spaces. This rating allows for discreet installation above the ceiling, this minimizes tampering and theft while keeping connections and cables protected and accessible. Most of our Roemtech amplifiers, excluding the DMA-355H, are plenum-rated and built with extra-durable components to withstand very high-temperature environments. Roemtech sets the standard for reliable and ultra-durable plenum-rated amplifiers at a competitive price! Made in the USA.
