I was the Pilot-in-Command. While descending we received multiple aircraft failures including an IC600-1 failure; AHRS 1 failure; Autopilot failure; Yaw Damper failure; SPS Advance EICAS Caution message and other associated failures resulting from the IC600-1 and AHRS 1 failures. We declared an emergency with ATC and notified dispatch. We also alerted the Flight Attendant who then informed the passengers. We complied with all AOM-1 and FM-1 policies and procedures and the flight landed safely at without further incident.
