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.

    As reviewed by Noah Montena on 6/8/2010

    Making music "in the box" still requires live sources - anything from vocals for vocoding, to guitars for mangling - and interfaces with only line inputs need a preamp. The Grace m501 is that preamp. It handles every type of microphone, and has a DI socket on the front for guitars and basses. Gain and trim can handle a very wide range of input levels, and it has a switchable low-cutoff filter to minimize studio background noise. And because it's 500 series format, you don't have to stay in the studio. Stuffed in an API 500-6B lunchbox you can take it anywhere, or it can stay in your rack in a 500VPR. Transfer only requires two screws, and no wires. This is also one of the best looking lunchbox modules, with heavy-duty buttons and knobs that don't look like you got it from a ham radio fair. You also can't beat the price: most 500 series modules start around a grand. These are worth the short wait while Grace builds you one. They even come with the signatures of everybody there. When was the last time you got something that didn't come from a faceless corporation?
