I'm having a problem with triggering my DaLite Tensioned Contour Electrol, which has a built-in 12v triggering relay to drop the screen. My projector (sanyo plz-v3) does not have a 12v trigger, but my Marantz SR9300 does. I'm running into the same problem that others have mentioned here, where the AV trigger does not supply enough amperage to trip the relay in the screen, which needs a minimum of 83mA. The marantz only puts out 44mA. When you connect everything together, and try to trip the screen, the voltage drops to nearly zero. does anybody have a solution for this? I'm willing to try to build something if necessary, but I would prefer a one-stop shopping solution... Is there a device that can take a low amperage 12v, and send out a 12v signal at higher amperage? (is this a transformer?) many thanks for any help on this!
