We are getting many reports from people in the field that are using their BRC as the clock for their ADAT transfers with the HD24 and they are getting clicks and pops. Alesis has confirmed that there are some SUBTLE issues with the BRC because of the new technology involved in the HD24 - the BRC is very sensitive to this unit. They recommend using the 1st adat in the chain for clock and a LRC for that for transport ...this is a temporary work around. Alesis is working on a solution...
