Hi,

I'm using a 2x4HD for crossover and EQ for a 2 way speaker today and it works great. I'd like to try 3 or 4-way speakers. Will feed the DSP with SPDIF/TOSLINK/USB via CD Player, Media Streamer or Computer. Outputs will be fed to different amps. e.g 3 amps for a 3-way + 1 for sub. Thought of getting the 4x10HD but its not available. Took a quick look into C-DSP 8x12 V2 manual (section 4.10.5 except driven via the digital inputs) and looks like it will work just as well although it has more outputs than I need. I understand that DIRAC is for room correction but I don't know how to configure or whether I need it. Looks like it's optional so that's fine. Good to know I have it if I want to use it. The ONLY thing I don't get I think is USB audio input. Is that right?

Regards,
Ravi

Two more things..
1. How do I use REW to measure my speakers if I can't play via the USB input? With the 2x4HD I connect it via USB to laptop and use REW.
2. A power supply isn't included so I'll need an 12V supply.
 

1. This would be the same as the 4x10 HD, you need to get an analog or digital signal from the computer. Have a look at the app notes.
2. It's designed for use in a car.

The 8x12 is a very powerful dsp 

it will do about anything you could ever want 

the DL version is the one to go for.

and it has 4.5v out…. So plenty of headroom 

HOw to power C-DSP though? Will this work Anbull SMPS 110V AC to 12V DC Converter Power Supply Adapter Switch Transformer Max 50A 600W ?

Or this Aclorol 12V 10A 120W Power Supply Adapter Converter Transformer AC 100-240V to DC 12volts 10amps

I am trying to do the same to EQ my 8 subwoofers

Yes that’s fine 

pretty much any 12v outlet adapter will
work 

it just needs a 10A max output 

I think the all the miniDSP products that do not have a power amp output need a supply with 0.8 to 1.2 amps out. I am powering a Cdsp 6x8 with .8 amps out. It has replaced a nano avr. Seems to work. I use a usb to spdf converter for REW.
 

Signstek HiFi USB to Coaxial S/PDIF Converter Convert Digital to Analogue Signal Mini USB DAC PCM is what I used

Can’t overpower 

you could hook up a 50000000A capability power supply, it’s the electrical resistance that determines how much it will actually use , 
so no , no such thing as over powering
