It is perfect for working with older ribbon microphones. Its microphone preamp with 80 dB of gain accurately recreates the vintage sound. The line mode with 50 dB of gain allows you to re-amp previously recorded tracks.\u003c\/p\u003e\n\u003ch3\u003eDMA73 Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo Class A Microphone Preamps\u003c\/li\u003e\n\u003cli\u003eTwo Class A Line Preamps\u003c\/li\u003e\n\u003cli\u003eCarnhill Input and Output Transformers\u003c\/li\u003e\n\u003cli\u003e+48V Phantom Power\u003c\/li\u003e\n\u003cli\u003e20 dB Microphone Attenuation Pad\u003c\/li\u003e\n\u003cli\u003e18 dB per Octave 80 Hz High-Pass Filter\u003c\/li\u003e\n\u003cli\u003e3 Gain Stage Modular Card Construction\u003c\/li\u003e\n\u003cli\u003eMarconi-Style Knobs and Engraved Button\u003c\/li\u003e\n\u003cli\u003eExternal Linear Power Supply Reduces EMF\u003c\/li\u003e\n\u003cli\u003e1RU Module Fits 19\" Rack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDMA73 Specs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMicrophone input impedance: High=1200 Ω minimum; Low= 300 Ω minimum.
