Details
Controls: boost button (switches between >2x and 4x gain boost)
I/O: 1x XLR input (from mic), 1x XLR output (to preamp); inline between mic and preamp
Notes: FLAG: device_class set to 'Preamp' per task guidance -- functionally an inline phantom-powered gain booster for passive ribbon/dynamic mics (Cloudlifter-style), not a full mic preamp. Draws 48V phantom power from the downstream preamp to run its internal Class-A stage while isolating the passive mic from phantom voltage; boosts gain >2x standard, up to 4x with boost button engaged. Royer states 'Assembled in the USA'; exact facility not specified so country_of_manufacture inferred as USA. Dimensions/weight (1.6 x 2 x 3.6in, 6oz) and connector details sourced from third-party retailer listings, not the royerlabs.com product page itself, so omitted from structured spec fields to avoid mixing sources beyond page confirmation; price_usd = Sweetwater street price (USD).
