Handmade in the USA

The Summit 2BA-221 Mic/Line Preamp features the rich, clear tone and compact design that Summit Audio has built its name on since 1979. Constructed with the highest-quality full-voltage tube and solid-state signal paths, it has a dedicated power source for its 48-volt phantom power so as not to draw current away from the main circuits.
