MDB-1 Combination preamp, direct box, buffer.
Long out of production. Applications include: Raven Labs MDB-1
  • Buffer. Because of the low noise and high input impedance, the MDB-1 makes an extremely good buffer amp. For example: between external pickups, both piezo and magnetic, and amp; instrument(s) and recording on a computer; anywhere you need to go from a high impedance to a low impedance. Using the MDB-1 will insure all the information from your source will remain unloaded.
  • Mixer. Since each channel is completely independent, you can mix and blend up to 3 sources. Select the source desired one at a time or all three together.
  • Direct Box. The balanced XLR out is extremely accurate and very quiet. Perfect for professional and home recording.
  • Preamp. Great for passive or low level instruments.
  • Recording. Direct to tape if desired.
  • A/B box. For low level sources (i.e. keyboards, guitars, preamps).
  • Blending. Blend instruments with stereo or dual outputs to mono, such as acoustics with piezo and mic outputs or Alembic stereo basses.
  • Level equalization. Preset the volume of instruments having different output levels during "soundcheck" thus eliminating problems during the live performance.
  • Home recording
  • Post production work in the audio/video industry.
  • Use in conjunction with computers and recording to disc or DAT.
  • Compact, goes anywhere. No external power source needed.
  • From the Raven Labs Website: "The MDB-1 is a combination mixer/direct box/buffer/preamp in one small unit 6.7" wide x 1.75"high x 6"deep, and weighs approximately 2 lbs. The MDB-1 boasts an incredible 10 Meg ohm input impedance making it the perfect buffer for any instrument. Coupled with super low noise (-95dB typical), distortion (0.005% @ 1KHz) and a frequency response from 10Hz to 60KHz, makes this one of the finest pieces of equipment in its category. Input headroom is 2 volts RMS. Maximum gain is 3X with "unity" being at 12 o'clock on the volume control.


  • does not include AC adapter but you can get the power supply from a company called Torres Engineering.
