Audio Issues from using a facility microphone sytem

We use zoom to provide video and audio for individuals meetings. We are receiving complaints from listeners regarding the audio volume. We have our computer connected to a mixer board that controls the volume for the building’s microphone and speakers. Any suggestions to address the volume, without blowing the speakers and blowing the ear drums of those physically present?
