Details
Controls: per-channel gain switch: mic mode 12dB/20dB; DI mode 0dB(unity)/8dB
I/O: 2 independent channels, each usable as mic booster or instrument DI simultaneously
Notable use: Royer recommends pairing with R-121, R-10, SF-12 ribbon mics and dynamic mics like the SM7B and RE-20 (per Royer marketing copy).
Notes: FLAG: device_class set to 'Preamp' per task guidance -- second-generation, dual-channel version of the dBooster that adds an instrument DI mode alongside the mic-lifter function; each channel independently switchable between mic-boost (12/20dB) and DI (0/8dB) modes. Protects ribbon mics from phantom power reaching the ribbon element while drawing 48V phantom to power its own Class-A stages. Royer states 'Built in the USA, shipped from Burbank headquarters.' Price = Sweetwater street price (USD); introductory street price was reported at $299 (Jan 2022 launch) before rising to current $349.
