Know before you buy
The Ribbon mode increases the input impedance to 20 kOhms and intelligently bypasses phantom power. This prevents potential damage to delicate ribbon elements while ensuring the microphone receives the correct load for optimal performance.
Yes, the m101 includes a dedicated Hi-Z 1/4" instrument input on the front panel. This allows you to plug instruments directly into the preamp for a clean, high-fidelity signal path without needing an external DI box.
The gold-plated rotary switch provides precise, repeatable gain settings. This is particularly useful for stereo matching if you eventually acquire a second unit, or simply for recalling exact gain levels for specific microphones and sources.
Absolutely. With a gain range starting at 10dB, it provides plenty of headroom for high-output condensers, while the 75dB maximum gain ensures you have enough clean power for quieter dynamic or ribbon microphones.
No, it features an internal universal switching power supply. You can connect it directly to any standard AC outlet (100-240V) using a standard IEC cable, which helps keep your workspace cleaner.
The m101 is designed to be exceptionally transparent and detailed. It does not add coloration or saturation to the signal, making it an ideal choice if you want to capture the true, uncolored sound of your microphone and source.
