A balanced, transformerless design with a trans-impedance (current feedback) gain core delivers the same transparency and detail as the larger Grace Design preamps, in a format that fits any 500 Series rack.\u003c\/p\u003e\n\n\u003ch3\u003eTransparent capture of the source\u003c\/h3\u003e\n\u003cp\u003eMost 500 Series modules colour the signal, which with a good microphone and considered placement robs the recording of fidelity. The m501 is designed the opposite way: to reproduce the source with minimal coloration and distortion. The trans-impedance architecture maintains a nearly constant bandwidth across the entire gain range, improving dynamics without adding a metallic, solid-state character. 0.5% tolerance metal film resistors and a 12-position gold-plated rotary gain switch give precise, repeatable channel settings.\u003c\/p\u003e\n\n\u003ch3\u003eRibbon mode and instrument input\u003c\/h3\u003e\n\u003cp\u003eAn engineer recording with ribbon microphones risks damaging the delicate ribbon with phantom power. The m501 has an exclusive Ribbon mode activated with a single push: it raises the input impedance from 8.1 kΩ to 20 kΩ, bypasses the coupling capacitors and locks out 48 V, protecting the mic and also optimising dynamic mic performance. A Hi-Z 1\/4\" instrument input with 2.5 MΩ impedance lets you record guitar or bass directly, and a 75 Hz high-pass filter removes boom and rumble before the recording chain.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-channel microphone preamp in the 500 Series format\u003c\/li\u003e\n\u003cli\u003eModular version of the m101 preamp\u003c\/li\u003e\n\u003cli\u003eBalanced, transformerless trans-impedance architecture\u003c\/li\u003e\n\u003cli\u003e12-position gold-plated gain switch plus 0 to 10 dB trim\u003c\/li\u003e\n\u003cli\u003eExclusive Ribbon mode with phantom lockout and raised impedance\u003c\/li\u003e\n\u003cli\u003eHi-Z 1\/4\" instrument input on the front panel\u003c\/li\u003e\n\u003cli\u003e75 Hz high-pass filter, 12 dB\/octave\u003c\/li\u003e\n\u003cli\u003e0.5% tolerance metal film resistors\u003c\/li\u003e\n\u003cli\u003eLED indicators for 48 V, Ribbon Mode and HPF\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer: Grace Design\u003c\/li\u003e\n\u003cli\u003eType: single-channel 500 Series microphone preamp\u003c\/li\u003e\n\u003cli\u003eArchitecture: balanced, transformerless, trans-impedance\u003c\/li\u003e\n\u003cli\u003eGain range: 10 dB to 75 dB (10-65 dB rotary in 5 dB steps plus 0-10 dB trim)\u003c\/li\u003e\n\u003cli\u003eRibbon mode: impedance raised from 8.1 kΩ to 20 kΩ, 48 V lockout\u003c\/li\u003e\n\u003cli\u003eHi-Z instrument input: 2.5 MΩ unbalanced \/ 5 MΩ balanced, gain -10 to +55 dB\u003c\/li\u003e\n\u003cli\u003eFilter: HPF 75 Hz, 12 dB\/octave\u003c\/li\u003e\n\u003cli\u003ePhantom power: 48 V switchable\u003c\/li\u003e\n\u003cli\u003eGain control: 12-position gold-plated rotary switch\u003c\/li\u003e\n\u003cli\u003eComponents: 0.5% metal film resistors\u003c\/li\u003e\n\u003cli\u003eOutput: balanced XLR (via 500 Series frame)\u003c\/li\u003e\n\u003cli\u003eManufacturer warranty: 5 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Grace Design","offers":[{"title":"Default Title","offer_id":54099997327697,"sku":"29823","price":869.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/GraceDesignm501MicrophonePreamp1.webp?v=1782212890","url":"https:\/\/wrdtunes.com\/fr\/products\/grace-design-m501-microphone-preamp","provider":"Wired Tunes","version":"1.0","type":"link"}
