The Grace Design m101 is a single-channel microphone preamplifier designed to deliver exceptional clarity, musicality, and detail. It features a balanced, transformerless, transimpedance circuit topology that ensures outstanding bandwidth and headroom, making it an ideal choice for capturing professional-quality recordings. The unit includes a universal power supply that accepts voltages from 100 to 240VAC, ensuring quiet and reliable operation in any studio or live environment.
For ribbon microphones, the Grace Design m101 offers a dedicated mode that optimises performance by bypassing input decoupling capacitors, increasing input impedance from 8.1kΩ to 20kΩ, and disabling 48V phantom power to protect delicate ribbon elements. The preamplifier provides a wide gain range of 10-75dB, adjusted via a precision 12-position gold-plated rotary switch, with an additional +10dB available through the output trim control.
Connectivity options include a front-panel HI-Z input for instruments, along with rear-panel balanced TRS, unbalanced TS 1/4-inch, and standard XLR inputs and outputs, offering flexibility for various studio and live applications. The front panel is made from durable black anodised material with laser-etched labeling for long-lasting legibility. Each function is clearly indicated by dedicated LED indicators, including those for phantom power and the high-pass filter.
Designed to complement a wide range of microphones, from vintage condensers to modern dynamics and ribbons, the Grace Design m101 delivers the level of high-fidelity performance typically found in high-end studio equipment. Its combination of pristine sound quality, rugged construction, and versatility makes it an essential tool for recording professionals and musicians seeking premium audio performance.
