Grace Design m101

Grace Design m101

In 2000, the model 101 helped fuel a revolution. When people took professional recording into their own hands, it was there with all of the quality and performance of a high-end mic preamplifier, but with a price that made it available to the masses. 8 years later, and the cause moves forward with the newly redesigned m101.

With its impressive list of new features, the m101 is ready to give any mic preamplifier a run for its money. Consider the new audio signal path with 0.5% precision metal film resistors, 12 position gold plated rotary gain switch, a built-in universal AC input module, or our exclusive RIBBON mic mode - and the picture becomes clear: This is now a fully professional, state of the art precision mic preamp that roundly outperforms anything in its class. All this at the same affordable price of the original model 101.

From podcast to concert hall, the m101 brings the build quality, refinement and performance to revolutionize any recording facility.
