  1. Demo video just uploaded to our D'Amore Engineering Video Manuals Playlist https://www.youtube.com/playlist?list=PLNMbsRIxVU1KMDzeKrXVV3gAqwVVX0kMn
  2. We made some product video manuals and a playlist. Subscribe to our channel and check back often as we add more video manuals to it. One or two still uploading as I type this. https://www.youtube.com/playlist?list=PLNMbsRIxVU1KMDzeKrXVV3gAqwVVX0kMn
  3. Too much power kills a sub, and clipping the signal is one way of giving it a lot more power (up to 200% more) without it getting much louder. This problem by itself would not destroy speakers, but it would not sound good. It has the same problem at 1kHz which sounds reallllly bad.
  4. Knowledge, send it in and we will take care of you. I don't know where you have been emailing but I can tell you it wasn't to me. We don't sit in front of computers during the day as we are the actual manufacturer, we are in the lab with soldering irons in hand all day. So sometimes it does take us a few days before we see an email. Either way, its all good, just ship it to D'Amore Engineering 1920 E. 3rd St. Suite 12 Tempe, AZ 85281
  5. @AMI, please send it to us, we will replace the light pipe. D'Amore Engineering 1920 E. 3rd St. Suite 12 Tempe, AZ 85281
  6. Are you connecting the probes to the speaker + and Batt - or the speaker + and speaker -
  7. Your results would be more accurate with more sub than the single 10, unless it has a really high Vas (at least half of the enclosure size)
  8. Guess I am the luckiest person in the world to get back to back defective products of a rarely sold item. That's like buying a Ferrari and it becomes a lemon. Than get another Ferrari and its a lemon too. The odds??? I posted this thread about 2 weeks ago for some direction and no one had anything to say. Now I call out a brand and now everyone has something to say about the kind of person I am. Amazing that you guys are blaming me but when I was being nice asking for advice, you guys were all quiet. Now my asking for advice has turned into me causing my own issues and making accusations, you guys all want to start pointing the finger at me. Really guys? How many SMD products do you own? I am in no way a hater. I am an installer and always looking to get any edge I can over other installers in my area. I use my SMD tools on the regular. Hell if Steve came out with a fkn screw driver, I'd probably buy that too. A forum is open dialog for people to connect. Last time I had an issue I posted a thread and Tony responded later the same day. I was pretty much expecting a similar interaction since he still is a partner in here. //////////////////////////// The AMM-1, like all of our tools has a auto-off timer that will shut it off after about 8 minutes to save the battery if accidentally left on. If you are deep in the middle of doing something and you are worried about it shutting off mid-test, just press the "ON" button occasionally, this will reset the timer. If it turns off and says low batt when turned back on, or just won't turn on at all, the battery is probably junk. Even "fresh" batteries if cheap or old might have problems. You need a quality battery like a duracell or energizer that has been made in the last couple of years. They ususally have experation dates on the packaging. About it not reading power, let's make sure the battery issue isn't an issue and then try measuring power again. You need both the voltage probes hooked to the amplifier speaker + and - and ONE of the speaker wires (the positive or negative doesn't matter but not both) going through the current transformer hole. As for the serial number, it should be behind the rubber boot on the tool above the battery door. We build all of these by hand, 100% in Tempe, Arizona. We do not buy these or outsource the labor and the same 2 people have been building them for over 3 years and over 6000 units now. I have no idea why a serial number wouldn't be there. Lets work though these items one at a time, I want you to enjoy using the AMM-1 as many others do. Tony
  9. Orion, we took the DD-1, added a microprocessor, an LCD, the HV high voltage internals, AC Voltmeter and proprietary firmware. It allows someone to find max headunit volume setting and set gain overlap of amplifiers with 0.1dB resolution. If you want 7.3dB of overlap you can set it like that. It also allows a shop to be able to check the gain overlap of a customer's system WITHOUT making any adjustments to their system. Also to recheck gain overlap settings if a customer returns for warranty. On top of all of that, it is actually even FASTER to use than the original DD-1.
  10. I finalized some changes to the firmware yesterday that includes a reset function for the DC min/max without cycling screens and some more filtering in dyno mode to deal with burping on a highly inductive load. If you would like the newer firmware, version 3.8 in your unit please send your AMM-1 to us, we will update the firmware, test the unit and ship it right back to you. Sorry there is not a way to remotely update it, but that would have added cost to the design and we don't anticipate any further firmware updates. Please send it here and we will take care of it promptly, and send it right back with a couple of D'Amore Engineering vinyl decals for your trouble.

  11. Connect the voltage probes to the same connections that you are using for output to the subs. Then run one of the speaker wires through the hole in the case.
  12. You could use these two tools together, or even just the IM-SG by itself. In audio the "crossover point" is what we call the frequency where the speaker is receiving half of the power it normally would. That being said lets do an example for a 4 ohm tweeter. Tools needed, IM-SG and a small 4 ohm resistor (1/2 watt or larger). Connect the resistor to the tweeter output of the passive crossover. If the crossover has jumpers for attenuation make sure they are set at -0dB. Connect the IM-SG to the input of the passive crossover, turn the freq all the way up to 20kHz. The impedance should read close to 4 ohms. Turn the frequency down until the impedance reads 8 ohms. This would be the crossover frequency. Let me know how it goes. Tony
