• MicroSD Cards with Echo Room Controllers and Echo-Echoflex Interfaces

    The Echo Room Controller and Echo-Echoflex Interface along with several other Echo products, can have their firmware updated in the field via a MicroSD card. However there are some MicroSD cards that will not work with these two products.

    In the event that this becomes a problem, ETC has a MicroSD card in stock that can be purchased. The part number for this card is: A157-F.
