Product Description
The Buzz Audio MIA-1.0 musical instrument adaptor (traditionally called a direct box) was initially designed to compliment the MA-2.2 microphone amplifier, converting unbalanced instrument inputs into a balanced mic level signals. This is achieved with a simple FET input, balanced output buffer amplifier. There are no transformers in the audio path, ground isolation is achieved by the use of a transformer in the hi-frequency power supply that converts the phantom power to the nominal 12V operating voltage.
The MIA-1.0 can of course be used with any mic preamp equipped with +48V phantom power (8mA). Users can expect smoother bass performance and excellent treble reproduction without the phase shift anomalies inherent in standard transformer coupled designs.
