Boulder 2110 Preamplifier

The 2110 is Boulder's most iconic and longest continuously produced preamplifier, built across four separate chassis for the left and right audio sections, user interface, and power supply, isolating each circuit.

It uses 12 high-current 993S gain stages, a modern descendant of Boulder's 990 gain stage originally developed for broadcast and recording studio use, with a balanced version of Boulder's analog discrete step volume control.

It supports bi-amp and tri-amp configurations and powered subwoofers, with user-nameable, configurable inputs.
