FYI. I bought the OTI-512 and it works like a champ. This item may also be useful if you are splitting your triggers and are worrying about the delivered current.

On another matter, when I first hooked up the trigger cable between the 1050 and my HTS-3000 there was a loud hum induced . I am using RS mic. cable for the trigger. I then connected the shield to ground/neutral on the 1050 side of the plug and left it unconnected on the HTS-3000 side. The hum all but disappeared. Nice to know that electronic theory sometimes works.
