Golden Age Project Pre-73 MKIII Mic Preamp Vintage Style electronics, no intergrated circuits in the signal pathEnough gain to handle passive ribbon mics with quiet sound sourcesGAIN/LINE mode switch, gain is reduced by 30 dB in LINE modeSelectable two position high frequency AIR boost eq, 3 or 6 dB @ 30 kHzSelectable 6 dB/octave two frequency high pass filterTantalum capacitors in the signal pathSwitchable impedance in MIC modeSwitchable phantom power and absolute phaseA high-impedance instrument inputA simple but effective 4-step LED o The signal path uses only discrete components like resistors, capacitors and transistors The input and output is transformer balanced, using two different transformers, each one optimized for its purpose This is the way audio components were built before integrated circuits became available The circuit used in the PRE-73 MKIII is similar to the preamp section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical
