The trigrer wire (cable) has a mini jack and uses a siganl from a a processor or receiver that has the capabilites of sending a signal to a componet to power it on and off. I will be using the Axiom balanced cables with trigger wire for my 600s, one from the EQ (still making a decision which type to use) and a second cable to connect the two 600s together, since they will be co-located.



There is no real need to power the 500/600 off, as it does have a power saving mode, when no sigal is present, it goes into a standby mode, and has minimal power useage.

The USP port serves two purposes, first would be for connecting to a computer for any future firmware upgrades. Second, available from the Axiom store is the USB Light, which is compatable with any USB device, and works well on the 500/600 if you have either placed in an area where light is needed for adjustments to the subs.
