 ● Accessories, MX-40 / C-130

The set comprises C-130 microphone and PA-13 preamplifier.



The C-130 condenser microphone has been developed to supply the sector with greatest demand for precision measurements of sound pressure.
The use of materials such as nickel and monel and exhaustive quality control, make the C-130 a highly reliable microphone.
By virtue of its size, type of thread and contacts the C-130 is interchangeable with most makes commonly found on the market, which also facilitates its calibration in official laboratories.

The PA-13 preamplifier is designed for half-inch microphones such
as the CESVA C-130 and comparable types. By virtue of its wide frequency response and low noise level, the PA-13 is ideal for precision applications. It is also very reasonably priced.
