Beyerdynamic TG D71 Condenser Boundary Microphone

The BeyerDynamic TG D71 is a half-cardioid boundary microphone designed for miking bass drums without the need for additional mounting materials. The high impulse fidelity and max. DPL of 148dB makes the D71 ideal for capturing percussion, as well as grand, and upright pianos.

The rugged housing in a slim, compact design protects the microphone against damages in the rough daily use on stage. For a permanent installation on a surface there are two mounting holes at the bottom of the microphone. The microphone is provided with an integrated pre-amp and can be powered on microphone inputs supplying 11 to 52 V phantom power. A red illuminating status LED displays the applied phantom power and in this way the operating status of the microphone.
