Technical Specs

Being a multi-use facility means endless possibilities in how we set the stage for your event or production. Whether you are having a music concert that needs the orchestra shell, a dance performance that needs the soft goods hung, or a lecture that needs the film screen in, the Tsai Center is capable of providing a large variety of stage setups. Our friendly in-house professional staff can assist you in making choices that best meet the needs of your event. We encourage everyone to review our tech specs below to learn more detailed information about lighting, sound, multimedia, and equipment inventories.

Student Staff

The Tsai Performance Center has approximately 30 Boston University students who work alongside the professional staff to handle the technical and front-of-house needs for all our events.



Driving directions are available on BU Maps, both for directions to our front door and directions to our loading dock doors behind the theatre. We strongly recommend that you talk to your Tsai production contact person at least one week prior to your event if you will be traveling by truck as Boston can be a tricky place to navigate.

The loading doors lead to a ramp that rises from the parking lot level to an orchestra pit elevator that then lifts to the house and stage levels.

Loading Doors dimensions: 81.5” H × 60.75” W (101.6” Diagonal)
Orchestra Pit Door dimensions: 78.5” H × 53.5” W (95” Diagonal)
