C L A S S - A D I S C R E T E M I C P R E Robbie is a Class-A discrete tube microphone and instrument preamplifier. With no ICs and only the highest-quality discrete components from input to output, Robbie is one of the quietest (-131 dB EIN @ 50Ω) and most detailed (THD 0.006%) tube preamps available today.
Robbie operates at 115VAC with USA power supply, or 230VAC with European power supply. Connect the male end of the AC power supply cable to Robbie by lining up the large top center tab with the large top center slot on Robbie’s female AC input jack. Make sure the cable is inserted fully into the jack and then gently twist to the right until it clicks into place.
