GRAS RA0086 Transmitter Adapter for 1/4" microphones
Length: (excl. connector): 37.5 mm
Diameter: 6.35 mm
Material: stainless steel
The GRAS RA0086 is similar to the GRAS RA0067 but is used with a 1/4" externally polarised microphone (typically a GRAS 40BP) which can then be used as a high-impedance sound source, e.g. when calibrating an acoustic coupler such as the GRAS RA0045. The RA0086 has a microdot connector.
Technology
Introduction
This accessory makes an externally polarized 1/4" microphone cartridge (typically a GRAS 40BP) behave like an electrostatic loudspeaker which, in a coupler, has a frequency response as good as when used as a microphone. It takes a calibration signal directly from a signal generator. The GRAS RA0086 has a Microdot connector.
