The C-80 from Sony is a uni-directional condenser microphone with a dual diaphragm configuration that stabalizes the recording and distribution of sound characteristics that change with distance. (proximity effect) "Noise Elimination Construction" succeeded from C-800G/C-100 prevents acoustic vibration resulting in low noise and clear sound. Inheriting the microphone capsule used in the C-100 and using the same material as the C-800G for the diaphragm, this microphone inherits the essence of the predecessors. The C-80 delivers professional-quality vocal recordings with a powerful and rich midrange along with a hint of added presence to cut through the mix. 
 
The large-diaphragm condenser element yields a true frequency response of 20 Hz to 20 kHz, with a dynamic range of more than 125.5 dB. The C-80 plays quite nicely, even with loud singers, as the capsule offers a -10 dB pad and can handle SPLs up to 138 dB. A high-pass filter is also on board to help reduce low-end rumbles and other unwanted low-end frequencies, while a suspension shockmount is included to isolate the mic from vibrations and handling noise. A carrying case is also supplied for storage and transport.
 
Dual-Diaphragm Design
At the core of the C-80's excellent sonic character is the dual-diaphragm microphone element, which helps to minimize proximity effects for sonically consistent recordings. In addition, the cardioid polar pattern focuses audio capture at the area around the mic, reducing unwanted sound from the rear and sides.
 
Exceptional Signal Response
The large-diaphragm condenser element yields a true frequency response of 20 Hz to 20 kHz with a dynamic range of more than 125.5 dB. The result is a flat-frequency response that maintains detail with low signals and transients. With a high sensitivity of -30 dB/Pa, the C-80 microphone can capture subtle nuances at high frequencies with low noise levels and minimum distortion.
 
Aluminum Body
The C-80 microphone incorporates a two-part aluminum body that helps to prevent acoustic vibration from reaching the microphone capsule, resulting in clarity of sonic reproduction.
