With the DM1, sE Electronics offers an active inline preamplifier for passive microphones that require extremely high preamplification. The DM 1 Dynamite is ideal for this and can easily be placed between the microphone and mic preamp to get extra transparent and clean 28dB GAIN - without any noise or discoloration. The output impedance is also the lowest in its class. Long cable lengths can thus be easily mastered while reducing susceptibility to interference, humming and humming. (Of course, the shorter the cable, the better). And of course the unique dynamite design must not go unmentioned. This "explosive pole" makes something in every studio!
