A microphone preamplifier module that brings out the very best in any microphone

The m501 is Grace Designs 500 series module version of the venerable m101 mic preamplifier. Now the signature transparency and detail of Grace circuit designs is available for your 500 series frame.

While the 500 series market has plenty of colored mic preamplifier options, the natural, musical clarity of the m501 makes it a welcome addition to the field. This circuit is for audio engineers who are confident with the quality of the source, mic section and placement, and wish to capture it with as little coloration or distortion as possible.

The m501 module is a balanced, transformerless preamplifier, with 48V phantom power, a 75Hz HPF and a 1/4" HI-Z instrument input. Also standard is Grace Design's exclusive ribbon mic mode, which raises the mic input impedance, bypasses the input decoupling capacitors and deactivates 48V phantom power to protect delicate ribbon mics from damage.

Large diaphragm, vintage ribbon or trusty dynamic—the Grace Design m501 brings out the very best in any microphone and takes the guesswork out of your input chain.

  • Balanced, transformerless preamplifier
  • Grace's exclusive ribbon mic mode
  • 48V phantom power
  • 75Hz HPF
  • 1/4" HI-Z instrument input
  • Fits 500 series frame
