WebOct 27, 2003 · A Direct coupled amp has response down to DC: which means that if you put a constant 1 volt on the input you will get a constant 25 volts (or so) at the output. … In electronics, direct coupling or DC coupling (also called conductive coupling and galvanic coupling) is the transfer of electrical energy by means of physical contact via a conductive medium, in contrast to inductive coupling and capacitive coupling. It is a way of interconnecting two circuits such that, in addition to transferring the AC signal (or information), the first circuit also provides DC bias to the second. Thus, DC blocking capacitors are not used or needed to interconnect the circ… personalized aunt and niece shirts
