How I can install it ?

From main or aux output on mixer, to input of one of the two channels on Dbx2. outputs of Dbx2, to power amp or powered speaker. If mixer has aux insert, you can plug into that. My mixer doesn’t have inserts, so I connect it the first way.

How to turn power off for this product? There is no switch or instruction

Our system is powered through a power conditioner. I turn it on and off with the rest of the system via the switch on the power conditioner. They may not have a power switch to keep it from being accidentally turned off during use, which could have disastrous consequences for the rest of your gear and everyone's ears. Great unit though. Have had no problems with feedback during church services since installing it. I highly recommend it.

Can you output from channel one to channel two to thus have 48 filters in mono?

The question is why? You should be able to do what is necessary with the 24 per channel. I don't believe the item can be used as you describe.

How do I set it with dbx eq 2231 and yamaha mixer?

You would daisy chain them. I would go from mixer to EQ to AFS2.
