Diamond Audio 1-Channel Full Range Class D Sub Amplifier

MICRO81U - 1 Channel Mono Block Digital Amplifier

Diamond Audio continues to break new dimensions by introducing the MICRO8U series of amplifiers for 2018. Following in the footsteps of the highly popular MICRO series amplifiers, the big-brother MICRO8U series packs more power and performance!

Developed and engineered from the ground up, these new amplifiers not only deliver more power, they are conformal-coated for all-weather application and outdoor environment use. All MICRO8U models have the same platform and dimension size (excluding the MICRO85U & MICRO88U) for a more aesthetically pleasing installation/fabrication set up to match its subtle, yet elegant cosmetics to give it that signature Diamond Audio visage.
