    here is an Ice Powered Hifi amp I built for $300.  I personally love the Ice Powered chips, as they have been used by many high end companies in their own amplifiers.  In fact, there are only two Class D amplifier boards currently that are called HiFi, Ice Powered and HyperX.  Here is what I used to build it.  along with a build video for anyone that wants to build one.   It is a simple build that I think anyone could build.  This will build one 200wx2 amplifier.

    Hi, quick question on this amp build. What is the final output per channel, and is it powerful enough to drive 6 ohm speakers? Appreciate your time!

    @melges

    And it’s definitely powerful enough to drive six ohm speakers. The way this about is built, it’s 200 Watts by 2 at 4 ohm. Probably cost to 150 x 2 at 6ohm.

    @123toid I was inspired by your YouTube video to build one of these ICEPower dual mono amplifiers. The build was strait forward and the amp appears to work however I do have a few questions that I would appreciate your feedback. 

    My current setup is a Yamaha TSR-700 AV receiver with full surround sound setup minus a center. I’m using the pre-out for front L&R speakers to the ICEpower amp to power Emotiva t-zero+ tower speakers (4ohm). 

    I’m running into two primary issues.

    1. One, the FR and FL speakers are quieter then they where without the ICE amplifier. I have to turn the volume up much higher then before. Using the YPAO room correction on the receiver, the front left and right get a +3db boost while the surrounds get -4db cut. all of this just seems counter intuitive. My real issue is I’m turning the volume up on the receiver to hear dialog and quieter scenes and when action picks up I have to turn it way down. any feed back would be appreciated. 

    2. My second issue is the auto standby. I installed the jumper you recommend from Parts Express to the j4 header on the 200asc board but I don’t think the auto standby works. The LED on the amp never turns off and when I put my ear up against the speaker the faint amp noise never turns off. Is there an incorrect way of installing this. again any feedback would be highly appreciated

      These amplifiers are designed to be used with preamps so don’t have much gain compared to normal amplifiers. It’s probably that your analogue outs are providing a true line-level signal. Have you experimented with a preamplifier?

      @123toid Do these have a gain adjustment? I know some amp boards allow you to adjust the default gain for different use cases, usually with a jumper or surface mounted switch.

      As for dialogue clarity it’s either that your centre channel is too quiet compared to your other channels, the room itself masking the direct sound with too much reflected sound (usually echo like), try clapping your hands to hear if there’s any echoing/ringing. Or it could be your room EQ if you have it, or the speakers themselves.

    A very interesting morning…..At 9am FEDEX delivered my Ghent cabinet for an ICE amplifier build from China…..The amplifier boards showed up from Parts Express a few days ago. So I tear open the boxes and in 1.25 hours the amplifier is done. So simple to assemble, but no instructions. Using two YouTube videos I got it done. But it uses balanced inputs and I don’t have the adapters. I ordered them yesterday morning from Amazon……I plugged the amp in to just see it light up and as I did, like magic, my doorbell rang and the Amazon guy was handing me a package of balanced adapters!!!…….The amp works great. Lots of power and extremely quiet. Can’t hear a peep even with ear against speakers. Will be breaking it in and listening at length this evening…..A very interesting morning…..At 9am FEDEX delivered my Ghent cabinet for an ICE amplifier build from China…..The amplifier boards showed up from Parts Express a few days ago.

    @RoyB THat is looking nice! You assembles that fast! THe more I look at the different cases, the more I like the two tone. I am wishing I did that with min. But I didn’t.

    Is that the Ghent input board? If so, there’s a previous thread on how that whole thing works and how to switch between balanced and unbalanced. I will look for it later, gotta get home.

    No, the boards were bought from Parts Express….Not sure if they are the same boards as Ghent

    This build is really enticing but I’m actually curious if anyone has expanded the design for more channels? I have two potential use cases:

    1. to power my 4 atmos height speakers

    2. to power my whole home multi-zone audio (10 channels of audio in total – 2 channels across 5 rooms).

    @badz Really, the only limit to how far you can expand the build is your imagination on how to package as many units as you need, the space you have to work with, the power circuit you are plugging into, and your wallet.

    The first and second pretty much go hand in hand, creatively fitting all the amps needed into the area alloted.

    The third has to do with the total wattage available on the circuit you plug into. For example, a 110 V 20 A circuit will have 2200 watts available to the whole circuit. You have to take into account all other devices plugged in along the way. Subtract their average draws and that’ll be what’s left for your “master amp”. And really, you want to drop that down to about 80% availability.

    And 4th, well, only you know what your wallet can handle.

    So, yes, you can expand on the build.

    If you want to use the Ice Power supply, that will only power up to two more units each (so a total of three channels). I would imagine you could use your own power supply to power multiple boards if you want to. That is beyond the scope of what I normally do, so you would be better off talking to @tvor-ceasar or some of the other guys that handle more of that technical side. That is the great part of the community. Everyone brings a little something else to the table.
