The Edwards Audio Research LE-10 Mono Preamp brings your studio the warmth of vacuum tubes with a frequency response that goes beyond the spectrum of digital audio.

Edwards Audio consulted The RCA Tube Manual, the bible of tube technology, when developing the LE-10. They found they needed about 280V DC to ensure the tubes worked under optimal conditions. To make this happen, they designed their own power supply with this heightened voltage allowance. Many of today's preamps use only a fraction of this voltage.

The LE-10 uses high quality components such as Neutrik or Amphenol XLRs, Jensen transformers, hand selected tubes, quiet potentiometers by Bournes, quiet film type resistors, high quality capacitors and well designed printed circuit boards.


  • Frequency Response:  20hz - 20,000 hz ( -.8db at 20 hz / -1.75 db at 20,000 hz)

  • Microphone Input Impedance:  250 ohm balanced

  • Output Impedance:  600 ohm balanced XLR
