Can i connect 1 rgbw strip to each output with a different address, to control them individually? also what power supply would i need for 8 strips?

When the unit is set to DMX 8 bit, each DMX address controls one color/channel on the device. So if you set the start address of this device to 1, then DMX address 1 = Red, DMX address 2 = Green, DMX address 3 = Blue, DMX address 4 = White. If you set the controller to DMX 16 bit then DMX address 1 and 2 = Red, DMX address 3 and 4 = Green, etc. There are 8 outputs of 5 wires each on the controller. RGBW(V+). 2 outputs are powered by one connection to your power supply(DC1+,DC1- in the picture) with a max of 24 Amps for those 2 outputs from that one input (DC1). You will need to determine the max power consumption of the light you are putting on the 2 outputs to ensure they will not go over the max amp of 24 amps. There are 4 DC inputs on the controller each with a max of 24Amps. Your power supply can be more than 24 amps and it can split between more than one DC input. For example you can have a power supply of 100 amps split across these 4 inputs to power the lights. 4x24=96amps. Just make sure you do not put a device on the outputs that consume more than max 24 amps.

Can someone explain the dim/ct/rgb/rbgw (1-4ch) modes? does this use fewer dmx channels to control the banks of four outputs or something?

1. DIM (one channel) / CT (two channel) / RGB (three channel) / RGBW (four channel) control modes. 2. Each Channel independently.

How do you assign a different dmx addresses for each channel?

There are 3 buttons on the decoder: button 1 , button 2, button 3 . The three-digit display indicates the current DMX address when connected to a power supply. The decimal point of last digit will flash regularly when receives DMX512 signal normally. The three-digit display turns off without operation for 30 seconds, press any key to turn it on. DMX address setup Long press button 1 for two seconds to enter DMX512 address setup, the digital-display flashes, press button 1 to set the hundreds digit (0-5 are valid values), press button 2 to set the tens digit (0-9 are valid values), press button 3 to set the units digit (0-9 are valid values). DMX512 address are 1-512, when the DMX address is above 512, testing mode is enabled Long press button 1 for two seconds to exit DMX512 address setup, it also can be exited automatically without operation for 10 seconds.

What power supply is needed to run this?

It depends on the current draw of the LEDs you're using. This can support 12V or 24V LEDs, and it can support up to 96A total with four power channels driving two LED channels apiece. The MAXIMUM power supply it can handle is a 24V 24A per power channel, so a total of four of those per controller. So why not just get those? Well, they're expensive - they're large (larger than the controller) - and they draw a hella lot of power, way more than a 120V/15A circuit could provide. What we're using at my theater is "5050" RGBW 12V LED light strips, which draw 5A of current per 5m (16.4 ft) length. We typically run no more than 5m per LED channel, so we're not going to exceed 10A per power channel. So, we've chosen 12V 10A power supplies, four per controller and that does just fine for us. If you're using less lighting, you can get by with smaller power supplies. If you're using more, you'll need bigger.
