      Good morning folks.

      Ive been toying around with amps , speakers , cables since in was around 11.

      That was almost 50 years ago. I have left the hobby a few times but never for to long. Not to say I dont have a system or two or three set up at all times, I just take a break from upgrading and swapping out pieces.

      Well I back at it.

      I stumbled here after researching how to build mono blocks with two ICE125ASX2 modules I have.

      My ,retail purchased, monos got zapped by a lightning strike back in 18 and I thought the modules were toast. I bought two new ones and swapped them out and still no luck. So I sent them off to the manufacture for repair. Yeah I know I could have probably fixed them but the wife was tired of seeing them in my dinning room.

      So I’m here to see if I can get some direction on building mono blocks with these two boards.

      Thanks in advance for the help

      Definitely we can help.  These are really easy boards to do that with. I did basically the exact same build here, but I used it’s little brother.  Shouldn’t be much different. If you want the easy way out.  Then I would suggest buy the case and cables cut to length from Ghent Audio. He is only showing the stereo case, but if you email him, he should have a mono case.

      I did email them on Friday. I should hear from them this week.

      For me the biggest problem is understanding the tech terms. 

      Like when they say ” pull the pin low”, What does that mean? Also the signal needs to 180 phased? 

       

      Did you see where Tomas Audio on YT is referencing your 3000 amp for 300 video?

      Thanks for the help

      Kit

      Would this kit work?

      No worries, we will help you get it set up.  I did see the Thomas Audio video.  I even commented on it.  Seems he was happy with it for the price.

       …

      No problem helping you out with such terms. 🙂

      When they say “pull the pin low”, what they mean is that the voltage applied to that pin has to be below a certain threshold to meet the criteria of “being low”. This all depends on the design, but usually it means tying the pin to ground in some fashion, either directly or through a resistor. 
      “Low” has many states (as well as “high”). For example: if a full reference voltage is 5V, you could look at 0V as “being low”, and 5V as “being high”. However, there is usually a point or two between them that is the “switchover point”, possibly 2V and lower is “low” and 3V and higher is “high”, with the middle part being a hysteresis area that allows things to settle before changing. 

      If it’s the pin I’m thinking about, tying it to ground directly would be the course to follow. If you do a search for GHENT on the forum, you’ll see a thread that goes through XLR to RCA wiring that would be a good read.

       

      Signal needing to 180° phased – easiest way I can explain it is: if one input is connected correctly, with + to + and – to -, and the second input is connected backwards, with + to – and – to +, then they are 180° out of phase. Take a look at this pic:

      If you were to put the bottom one over the top one, the peaks would be reversed – 180°.
