TG D71c
Condenser Boundary Microphone
Order # 708.992
FEATURES
• Extremely rugged housing in a compact, slim design
• Optimal for Bass or Cajon drums
• Flexible use with low-frequency instruments
• Half-cardioid polar pattern for maximum gain before feedback
• High impulse fidelity and low attack time
• Undistorted transmission of even high volumes
• Powerful, natural sound
• Integrated pre-amp
• Phantom power 11 - 52 V
• Non-slip rubber bottom
APPLICATIONS
The TG D71c boundary microphone is primarily used for miking
bass drums while placing it simply without any additional
mounting material into the bass drum. The non-slip rubber bottom
makes sure that the microphone cannot shift by itself. In addition
to this the TG D71c can also be used for other low frequency
instruments such as cajon, grand piano or upright piano whereas
the compact design and the half-cardioid polar pattern ensure easy
positioning of the microphone. Due to its high impulse fidelity, a
low attack time and a maximum sound pressure level of 148 dB, the
TG D71c is suitable for miking percussion instruments.
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.
