Rocky Mountain International Audio Fest
October 8-10, 2021
Denver, CO
Fri-Sat: 10-6, Sun: 10-4


The Colorado Audio Society has always been the heart and soul of RMAF. Our original mission of creating an international, affordable and welcoming trade show is only possible because of our volunteers.

Over the years our volunteers have expanded from the original CAS crew to encompass friends from all over the world. The volunteers are a gift to all the exhibitors and attendees. Their vast knowledge of the audio industry and willingness to share this knowledge and enthusiasm enhances the RMAF experience.

The volunteers wear the RMAF brightly colored t-shirt every year so they are easily recognizable. If you are interested in becoming an RMAF volunteer, all you have to commit to is one or more four-hour shift(s) and a friendly attitude.
