The artwork is in the hands of the printer. Waiting for a quote. |
| Mike A:
While I am waiting for artwork to arrive I have been doing some cabinet wiring. I am wiring in a hi to low signal converter for the audio. I want to pull the PCB amplified mono signal down to line level so I can split it and feed it into a small stereo amp that will drive the two 8 ohm speakers. That way I can also plug a stereo PCB into this cab when I want to switch things up. It might be totally unnecessary. I am not sure. But mono PCB amps are typically designed to drive a single 8 ohm speaker. When you drive 2 8 ohm speakers depending on series vs parallel wiring you get much lower volume or worse with lower impedance you overdrive the PCB amp. Maybe this is why you see so many torched PCB amps. Any audiophiles here can feel free to correct me on this. I don't know a ton about it. I already had a converter from another project and they are cheap. |

I am not in a position to call myself an audiophile by any stretch- But I do know that when you wire speakers in series that the resistance is accumulative and that many people blow amps that way. 16 ohms is a lot for most little amps to push signal through apparently. I'm dealing with the same consideration on my jRok Multi-Williams at the moment- and I certainly don't want to fry that board. I believe if you crank audio output from a JAMMA board down as low as you can get signal out of that you can feed that into an amp and it should not blow the input side. They are all different of course and require experimentation I guess. I feel like 2.1 audio for an arcade machine is always fun if you can pull it off. |
