$175 Class D amp--120 wpc

OK I need help to hook up the Connex ps board I bought.

The connes board has a set of inputs from the tranny, they are AC1 GND AC2

On the ClassD ps board the center tap two wires are connected to
the CT center input, and the other green wire is hooked up to the
AC-L and the other blue wire is hooked up two the AC-N

So does the blue wire going to the AC-N hook up to the GND on the connex

Does the two CT wire hook up to the AC1

Does the green wire hook up to the AC2

Sorry this is the correct picture of the inputs

Sorry, I don't have an experienced opinion or definitive answer to your question. However, I suspect you join the two common wires in the center and the outside wires like the Class D power module. But wait for a more experienced opinion before doing anything.

When you get it all going, let us know if you think this setup is superior to the Class D audio heavy duty power board. Thanks!

He reported in the modifications thread that he got it figured out...

Did some reading on the modifications thread. I came away with the opinion that any differences will likely be subjective, subtle and dependant on the system's ability to resolve source material.

jtsnead, glad you got it going.

Thanks Roy

Cheap and Cheerful is Fun!

I have already assembled a SDS258 amp kit. Everything is going on fine. I am thinking of adding another amp board for additional 2 channels to power the surround. As this is for the surround only, I do not really need the 258. Is it OK to buy the cheapest amp from Class D audio to tap on the power supply from the SDS258 kit?

Anyone? Can I, for example, add a CDA224 amp to the SDS258 kit to build a 4 channel power amp?

You sure can! Heck, my case will take those two boards.

Thanks! I just want to make sure that the power supply will not go bonkers, powering two different types of amp.

+1 On jt"s case, I was able to mount the above ps board in his case
just had to angle it to line up two holes, did not have to drill any,
easy as pie.

Shouldn't be an issue...just let Tom know what you're planning on.

Just finished the kit with the ti-600. Another +1 on the case. I am so happy with the sound I ordered another amp to make it a dual-mono. I want to revise some of my connections and wire pathways, too, and I'll post pics when that's all done.

Great! That was super quick too. Look forward to some pics.

Thanks for nice comments on the case.

Hi all,

After reading through half these threads, I'm interested in picking a CDA254 kit to drive a set of 4ohms Natalie P. I currently have the Onkyo RC180 which does 110w/ch x 7 and it does have pre-outs. If I were to pick up the cDA254 kit, would I still need to look for a pre-amp, or would the RC180 be adequate enough?

thanks

The RC180 will work fine.

I have Pioneer VSX-21 that does 110w x7 supposedly. When I tried my SDS-254 I noticed much more clarity, control, and soundstage vs using just the Pioneer imo.

I'm sure the receiver will be adequate. But how adequate enough? That's up to you...

Big #500 post. Yippie!

Okay now back to the action, I had the same response when i used my HK reciever and an SDS254. It totally blew away the HK in dynamics and was much much tighter sounding and a huge soundstage.

I put together an integrated amp: Hot Rodded DC Coupled B1 Mezmerize board with 3 inputs, and my CDA-254.

I am a big believer in reducing connections as much as possible and this seemed the best way to do between the two components. Also GF will hopefully be less irritated with having to turn on this and turn off that. Messy wiring will be cleaned up later. May also get an extension rod for the volume pot.

Well I am just about wrapped up w/ big audio projects for a while. Time to enjoy the fruits of my labors.

Wait what about that other girl? The Temptress 3020?
