These are great, I just which they had more ports. My amps don't have trigger outs so I can't daisy chain the triggers. That means with a 7.2 system I needed 4 3-port units. Once for left, one for right, one for center and subs and then one to trigger the other three. If they made a 6 or 9 channel unit that would have been preferred. I looked and 3-ports is the most I saw on the market.

Works great. Able to split the 12v trigger into multiple triggers and paired with an Iot Relay to turn on items without a 12v trigger input.

Easy

Too easy and so rewarding. Sometimes it's the simplest things that have a big impact.
