The Library of Congress requires contract support to modernize the audio systems for its historic Coolidge Auditorium, a 485-seat venue originally built for chamber music. The existing analog infrastructure is largely inoperable, forcing portable audio equipment to be set up for every event. The contractor will design and implement a new digital audio system to replace the analog setup, eliminating road cases and visible cable runs while preserving the auditorium's original acoustic quality. Performance of services will be at the Library of Congress Coolidge Auditorium. No budget or timeline details are specified in the description.
