I don't own any AC Infinity lights but the AC Infinity Controller 69 will work with other brand lights, I run x2 Vivosun VS4000, Spider Farmer SE4500, HLG Scorpion RSpec, and ViparSpectra XS1500 Pro each from a Controller 69.
The dimmer knobs on my light only have 5 levels, using the Controller 69 gives them 10 levels.
Your Hydra 3200 has RJ11 ports so I would think it would work with the Controller 69, you just also need either the AC Infinty RJ11 Type A or Type B adapter depending on the dimming style your lights use.
If you ever get one, make sure to get the Pro WiFi model, then you can control your devices from anywhere you have cell phone service.
AC Infinity is having a 10% off site wide sale plus you can stack promo code MRGROWIT15 for an additional 10% off and any order over $100 ships free.
