Rainbow Beat 4 Black Multi-channel Amplifier


The assembled printed circuit boards with SMD’s clean layout is well thought out and structurally characterised.

Product Description

Solid, all of a piece. Thus, the design of the BEAT is best described. The compact and powerful analog amplifiers are well processed and good “motorised”. The clean circuit boards with SMD layout is well thought out and structurally characterised in the small but effective power output. As known from the iPaul series also the top-control principle is used.
