{"product_id":"grace-design-m501-185022","title":"M501","description":"\u003ch3\u003eFrom the m101 to the m501: the same philosophy, adapted for modular racks\u003c\/h3\u003e\u003cp\u003eThe Grace Design m501 is the 500 series version of the m101 microphone preamplifier, known for its neutral reproduction and clarity. The goal remains the same: when the source is good, the microphone is well chosen and well placed, the preamp should not \"impose\" a signature but transmit the information with precision. In a modern environment where 500 series racks allow you to build a custom signal chain, the m501 brings this high-fidelity approach in a compact module, easy to integrate into a recording or reamping\/DI setup.\u003c\/p\u003e\u003ch3\u003eA preamp for demanding recordings, from home studios to professional studios\u003c\/h3\u003e\u003cp\u003eIf you are looking for a \"musical\" microphone preamplifier without aggressive magnification effects or artificial coloration, the m501 is an excellent choice for vocals, acoustic instruments, ensemble recordings, overheads, strings, or any situation where dynamics and timbre must remain natural. Its substantial gain reserve also facilitates working with low-output dynamic microphones, while the ribbon mode secures the use of vintage or modern ribbon microphones. Finally, the Hi-Z input allows direct recording of bass or guitar, with appropriate impedance and reliable relay switching.\u003c\/p\u003e\u003ch3\u003eTransparency, control, and innovations serving the recording process\u003c\/h3\u003e\u003ch4\u003eFast and stable design made to keep the signal intact\u003c\/h4\u003e\u003cp\u003eThe m501 is based on a \u003cstrong\u003etransformerless symmetrical design\u003c\/strong\u003e and a trans-impedance amplifier architecture, designed to respond quickly to transients and maintain a clean sonic image. The choice of high-quality metal film resistors (0.5% tolerance) in the audio path aligns with this goal: minimizing variations, reducing noise, and maintaining tonal coherence from one take to another.\u003c\/p\u003e\u003ch4\u003ePrecise gain and studio ergonomics\u003c\/h4\u003e\u003cp\u003eCompared to a continuous potentiometer approach, the \u003cstrong\u003enew 12-position rotary gain selector with gold contacts\u003c\/strong\u003e promotes reproducibility (session recalls, easier stereo matching) and a more \"measurement instrument\" feel. Add to this a high-performance line output stage and a high-level high-pass filter amplifier: the module stays clean even when pushing gain or when the session demands a wide dynamic range.\u003c\/p\u003e\u003ch4\u003eRibbon mode: more than just protection, a real recording tool\u003c\/h4\u003e\u003cp\u003eThe mode dedicated to ribbon microphones does more than just cut phantom power: it increases input impedance and bypasses the phantom power coupling capacitors via relay, while making \u003cstrong\u003e48 V phantom power activation impossible\u003c\/strong\u003e. Result: you protect the microphone and also optimize compatibility with certain dynamic or ribbon microphones that appreciate a higher load, for more stable low end and a more natural \"breathing\" sensation.\u003c\/p\u003e\u003ch4\u003eLess interference, more confidence\u003c\/h4\u003e\u003cp\u003eIn the studio as well as in dense installations (multiple power supplies, lighting, networks, RF), the \u003cstrong\u003eenhanced HF interference suppression\u003c\/strong\u003e helps maintain a clean noise floor. With its LED indicators (phantom power, ribbon mode, high-pass filter) and black anodized front panel with laser etching, the m501 is designed for intensive daily use.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFive-year warranty on parts and labor\u003c\/li\u003e\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:2;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003emicrophone preamp\u003c\/td\u003e\u003ctd data-r colspan=\"2\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:1;--wb-r:9;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFormat\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e500 Series module (modular version of the m101 microphone preamplifier)\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eHigh-pass filter\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e75 Hz\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:2;--wb-r:10;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003ePhantom power\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e48 V\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eSpecific mode for ribbon microphones (also excellent for dynamic microphones)\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003ephantom power decoupling capacitors bypassed by relay, higher input impedance, and 48 V phantom power cannot be activated\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:3;--wb-r:11;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003etransformerless balanced\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eInstrument input\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003edirect high-impedance (Hi-Z), 1\/4\u0026quot;
