The G.R.A.S. RA0063 adapts a 1/8" microphone cartridge to a 1/4" preamplifier. To reduce the attenuation of the signal, the guard ring of the preamplifier is extended through the RA0063.
For improved high-frequency performance by reducing diffraction effects, see the extended length adapter RA0082.
