Rode D-POWER-PLUG

The D-PowerPlug is effectively a turbo-charger for Dynamic microphones. It features an instrumentation grade pre-amplifier circuit and will turn any standard dynamic microphone into a high level electronically balanced output device.  It uses conventional microphones with long multi-core cables, resulting in a dramatic loss of signal strength, and of course sound quality due to cable resistance and capacitance.  Powered by standard P48 V, D-PowerPlug can drive cables in excess of 100 m with negligible loss of signal quality or power.
