Description

Buzz Audio MIA-1.0 Musical Instrument Adaptor - DIRECT BOX Details

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. Very nifty !!

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.

Buzz Audio MIA-1.0 Musical Instrument Adaptor - DIRECT BOX Features

Zero feedback Class A buffer amplifier, no audio transformer.
Real rubber feet - not self adhesives that drop off after a week !!
Three auto selecting inputs optimized for different levels...
- AMP IN is for the connection of speaker level signals, eg, the main output of a bass amplifier.
- LO-Z IN is for the connection of a line level device such as a keyboard or sampler or CD player output.
- HI-Z IN is for the connection of high impedance pickups, eg, bass guitar or acoustic pickups.
Three useful outputs...
- HI-Z OUT
  This is a loop output of all 3 inputs. The AMP IN signal is available on this jack at -35dB. The LO-Z IN signal is -6dB. This is very handy for "re-amping", ie, taking the speaker out of a amp and feeding it into another amplifier.
- BUFFER OUT
  Provides a buffered unbalanced version of the HI-Z OUT.
- BAL OUT
  The main output to the mic preamp and power source (+48V phantom). Ground lift to isolate input/output earths.

Applications

All acoustic pickups
Bass and electric guitars
Synths and samplers
Re-amping
