Tech questions for japanese cab owners *UPDATED*
<< < (2/2)
stellarola:
OK, I've been doing a lot of reading and research on getting everything in this Candy cabinet hooked up. I made a little diagram of how I will connect the video stuff. That part is cake for me. Now I found a little interested piece of information, I don't know if this is new to you all or anything, but... I have some of these Creative Inspire 2.1 350. The amp outputs 4ohms and the arcade speakers output 8 ohms each. I searched google and found this quote in a forum:

"When you connect two 8 ohm speakers together in parallel it brings it down to 4 ohms.. You take the positive wires from 2 diff speakers and connect them to 1 of the positive connections on your amp, then you take the 2 negative wires from your speakers and connect them to 1 negative connection on your amp. And then you do the same for the second channel. So with a 2 channel 4 ohm amp you can hook up 2 sets of 2 8ohm speakers."

Also was included a site and a little program for ohm calculations. So it looks like I have sound covered as well as video connections.

Now controls, I'm not going to use a J-PAC. I don't want that advice. I already have a x-arcade encoder connected to a serial switchbox so I can with a flip of a switch go from PC to Dreamcast.

So again now I have sound, video and controls taken care of.


The last order of business is power. I need to know 2 things...

-Can a standard 120vac isolation transformer be used on the monitors in the candy cabinet (this is also referring to those with other Japanese style cabinets). I don't really know if because it's Japanese it uses another kind of transformer, or if it even requires one.


-How do I hook up marquee lights? Does this go through the power supply? I'm a little lost on this subject. If anyone can point me in the right direction, it would be much appreciated.



I belive this is all that is left, thanks in advance. Below are some of the pictures I was talking about. My little doodle of a diagram I made at work and a picture of that ohm program set to 4ohms on the amp. :D

Oh, sorry heres that link http://www.bcae1.com/spkrmlti.htm
ShinAce:
Here's an impedance calculator for you to use.

Impedance of each speaker / # of speakers = total load

So if I got 8 ohm speakers, and 6 of them hooked up in parallel, I get...

8 / 6 = 1.333 ohms

Ok, if anyone wants to answer any of questions, that would be great. :P
