ICEpower 200ASC Class D Monoblock Build
I recently completed building a pair of monoblocks using the ICEpower 200ASC module and Ghent Audio ASC200-MXR case. Here are the details:
- Mount power button in front panel.
- Mount front panel on bottom of case.
- Mount ICEpower board in case.
- Mount feet to case. One of the feet will line up below the power socket and one of the screws will be longer than the others. Use the long screw where the power socket will be located when the back plate is attached.
- Attach ground wire to the long screw and fasten it with the washer and nut.
- Mount power socket, speaker connectors, XLR connector, RCA connector and RCA/XLR switch in back panel.
- Mount back panel on bottom of case and run the power cable from the power socket to the power switch (Neutral to Neutral, Live to Live). Also connect the ground wire mounted to the chassis through the foot screw.
- Run power cable from connector P2 of the power switch to connector P1 of the ICEpower board (Neutral to Neutral, Live to Live).
- Using two cables (soldered together) connect P4 of the power switch to connector J5 of the ICEpower board (- to Pin 1, + to pin 2). Pin 3 is unused and you can trim/remove the unused wire.
- Connect the cable to J4 and turn it into a jumper (solder).
- Run output cable from J2 to binding posts (solder) (Pin 1 to +, Pin 2 to -).
- Run input cables from J3 pins 6, 7 and 8 to the RCA/XLR switch, RCA connector, and XLR connector. Pins 1-5 are unused and you can trim/remove the unused wires. You can use the unused wires to solder the connections between the connectors. Use the wiring diagram below as a guide (note that the physical arrangement of Pin 1 and 2 of the XLR are reversed. Use the number on the connector to make sure you’re going to the right one). It will be hard to reach the pins with your soldering iron so you might need to remove some connectors or loosen the back panel to get it all done.
- That’s it! Test it out to make sure everything is working with both inputs. Put on the top cover and you’re done.
Excellent write-up! I'm going to have to add this to the video, for anyone that wants to do the monoblock build. T for taking the time to do this!
@123toid Your $3000 for $300 video inspired me to give this project a shot. I felt the best way I could pay it forward was to clearly document my build and share it. I hope others find it useful.
looking for a project to complete during lockdown. Just finished GR research x static build and would like to try mono locks. Never did anything like that other than put together a few crossovers. Looks a bit intimidating but that’s how I felt with the xstatics.
importantly, how is the sound quality?
I don't think this build is any more difficult than building a crossover. All you need is some basic soldering skills. The biggest challenge for me is that my vision isn't as sharp and my hands aren't as steady as they used to be. I just had to take my time and put on some reading glasses.
They sound great! They're so transparent and clear that they never draw any attention to themselves. I never feel like they're anywhere close to running out of power. There's no hiss unless you put your ear within an inch of the tweeter, either.
Overall, they have been more than worth the effort and expense. I don't see myself going back to a single stereo amp of any kind. Having monoblocks is just cool. 🙂
