  1. I would love the sub,but getting it to Mexico would be a big expense for me. Sent from my SM-T830 using Tapatalk
  2. Thank you, I was worried about high frequencies rolling off. I will just fun without buffers for now then. Sent from my SM-T830 using Tapatalk
  3. I thought that after last years CES...the audio manufacturers were not going to go anymore? I had heard they were moving to dedicated audio shows instead. Sent from my SM-T830 using Tapatalk
  4. I just found this... "Re: Red Dragon Audio Hi Cory, I use to frequent the Lounge but don't believe in Big Dan's idea of an entry level table. It just doesn't make sense to cut so many corners on a turntable….. It won't be designed by me [https://audioshark] Over the years i have had pretty much all class d modules in hand for testing. Some sound horrible, most sound good and only a few sound truly spectacular. Ice Power is so wide spread with many companies selling class d amps using Ice. All the boards are essentially the same, with different wattage ratings, some with SMPS and some without, some are stereo but most Ice boards are mono. All of them have a very low input impedance of 8-12kohms. Which is fine for 90% of pre amps out there but some like tube pre amps, have a very high output impedance, which is around 2.5kohms. This can present a tough load on the amp, the down fall is rolled off bass and less bass definition. The input buffer these companies are using, are very simple, they use JFET's or OpAmp's to raise the input impedance to a much safer level, around 40-50kohms. But the higher you go up, the more noise you'll get. Some companies have there inputs at 300kohms lol Here at Aluminati we have used various class d boards, most recently made an amp using the Ice Power 500asp board. Fantastic amp and we have one remaining!! Also make case solutions for nCore NC400 board. This board is for DIY only and just a few tools and a case can get you a true hi end amp. Class D is the only way i go. The highs have such shimmer and accuracy." Sent from my SM-T830 using Tapatalk
  5. These are not meant to be sold to the public. They are meant for OEM only. Parts Express is the only legit dealer I know of, and they do not sell buffers. Has anyone assembled a Icepower amp, and did they make or get a buffer? Sent from my SM-T830 using Tapatalk
  6. I have the 50asx2 in unbalanced.. From what I have read the input impedance drops quite a bit at the high frequencies, and they say you need an input buffer board. I have seen a lot of them for sale, and even plans, but I would like to buy one already built, and I have no idea which ones would be good either.. If it makes a favorable improvement, then I will look at getting 10 more for the 10nchannel DIY amp my friend is building for me. In that amp we have all of the amps in bridged/balanced mode. We have the 50asx2btl, and the 125asx2 which also will be bridged/balanced. I am hoping someone here will have experience with them, so I can find out how to know if I even need them. They will be driven by Xilica xp4080s. Sent from my SM-T830 using Tapatalk
  7. I have Icepower amp modules, and when we used them in my old setup we just installed them in a case. now we are building 2 amos, and a lit if people say I need to run buffers because of the variable impedance of the modules. Does anyone know how I would know if they are needed? If they are where can I buy some already made? Sent from my SM-G935V using Tapatalk
  8. Got it, thanks! Sent from my SM-T830 using Tapatalk
  9. Thanks, I have the 50asx2, and I have 3 of the 50asx2btls too. The btl versions are balanced in, but the other ones are single ended only. I have read about modding them,but I have not seen where anyone can verify that it works properly. Some of the people are saying they get hum or that it sounds very bad. I am a little confused... pin 3 goes to ground, and pin 1 goes to chassis ground. Shouldn't only one pin be going to the chassi ground, and the other 2 go to the amp module, or is pin 3 going to the negative of the rca, and pin 2 to the positive rca? The amp modules have rcas on them, and when we used them as unbalanced before we cut the rca cables to hook up to the rca jacsk... so this should be pretty easy once I k ow the way to wire it. So e people are saying it could burn up without a transformer...if so would it damage the icepower amp or the xilica crossover? Sent from my SM-T830 using Tapatalk
  10. Could I just not hook up the amp to the ground wire jack on the inside of the amp since it is not a balanced amp module? Amp is a Icepower 50wpc stereo amp module. Sent from my SM-T830 using Tapatalk
  11. Thanks,I know there areconvertors that will convery from balanced to unbalanced, and I believe also the other way... I just would prefer not to have to add another external device, and I cannot afford to buy 4 balanced amp modules for the horns when I have enough unbalanced modules for the job. I could always get 2 minidsp 2x4s, but I prefer to run Xilicas. Sent from my SM-T830 using Tapatalk
  12. Download a free SPL App for your phone so you can see what the SPL is, and at what frequency you are hitting the loudest. Sent from my SM-T830 using Tapatalk
  13. So I can run balanced from my Xilica to my amps which are not balanced, but will have XLRs because I prefer them, correct? What do I run the ground terminal on the XLR jack to for ground...amp chassis? Sent from my SM-T830 using Tapatalk
  14. I am installing XLRs on my DIY 4 channel amp that has 2 Icepower stereo amp modules in it. Would I just solder the 3rd wire to the ground pin on the XLR jack in the DIY amp? Sent from my SM-T830 using Tapatalk
  15. You beat me to it... I was going 5o ask the same thing. Sent from my SM-G935V using Tapatalk
