DESC: Designed specifically to operate the Multi-Mask Imager, Da-Lite's four-way masking screen. The MCIR involves three low voltage control units, which provide up, down and stop operation for each of the three masks. Comes standard with one remote transmitter and (3) three-button low voltage wall switches. Also allows a person to use a multi-purpose/functional IR remote with the Multi-Mask Imager, such as a Pronto remote.
