The A96F transformer connects microphones with an XLR-type connector to the 3.5 mm (9/64 inch) inputs found on camcorders and other recording devices. It increases the signal level from the microphone, provides a balanced input, and prevents distortion due to the d.c. bias typically found in camcorder microphone inputs.
The A96F can be modified for microphones rated at 150 ohms. This modification is only necessary if the output level from the A96F is insufficient for your recording device.
