Crown DL2 remote control

Has anyone built the remote control for the DL2? I was thinking of using this board http://store.qkits.com/moreinfo.cfm/QK142 to wire up to the pins on the DL2 to provide remote control. Only issue is that that input selection on the DL2 requires double pole single throw switches and the relays on the board in the link are single pole. Just wondering if anyone has done/what they used.

Thanks

I searched the Lansing catalogs for the Crown DL2 and can't find it anywhere? What year was it made?

Hmmm... maybe I posted in the wrong forum. It's not made by JBL. It's made by Crown. Maybe I should have posted in "Off Topic"?
