Goldline TEF04P
Phantom Powered Omnidirectional Electret Condenser Microphone


Goldline's TEF04 is a omni directional, 1/2" diameter, electret condenser microphone suitable for general purpose acoustical measurements and professional audio applications where a free-field omni pattern is specified.  The TEF04 provides levels of accuracy that meet the frequency response specifications of Goldline's more expensive titanium diaphram TEF05A mics, while providing the ruggedness of a mylar diaphram for field use.  The mic circuit has been designed to operate on phantom voltages from the 12VDC utilized by many RTA's to the 48VDC provided by mixing consoles and devices such as the TEF25 analyzer.  The precision machined stainless steel body provides exacting dimensions suitable for use with Acoustic Calibrators.
