  1. If you want to send your to us we can reprogram it for you with v3.93 and send it back. What has happened with the AMM-1 is that it was originally intended for use with sinewave sweeps and music, it originally shipped with v3.8 firmware and all was well. After people started playing with the AMM-1 they started doing sine-wave burps. When these burps are done with a Class D amplifier it causes a nasty back EMF spike when the burp stops. The AMM-1 would read this nasty spike and calculate power and display it. So someone testing a 1000 watt amp could burp it and get a 10,000 watt
  2. The sensitivity adjustment of the OM-1 should allow it to be used on amplifiers from 12V - 150VAC output. Is this a class D subwoofer amplifier that you are having the problem with?
  3. I know this is a very late reply and I apologize for that. As the info on this forum is permanent and searchable its good for the database so here we go.. Yes you would measure with the DD-1 probes ​across the bridge. Left positive and Right negative on most amplifiers. Yes the amplifier outputs (unloaded) will clip at the same point whether bridged or not. The bridge is just the two outputs channels running the same load instead of their own loads.
  4. I've tried Track 1 (40Hz 0db) Track 3 (40Hz -5db) and Track 5 (40Hz -10db). Wow if it won't clip with the 0dB track then it must have a anti-clipping circuit in it or some type of rollback circuit so that it can't be pushed too hard. I personally have not seen or played with one of these amps in person though I know that it is VERY similar to a model in the Hertz lineup and we have heard of people having trouble with that one as well. If the amplifier is not allowed to clip one may consider that an amplifier problem, not a DD-1 problem. The DD-1 is doing what it is supposed to do, alert th
  5. If you can get 1.8V out of the RCAs with Track 1, how many Volts do you get out of the speaker terminals with 1.8V going into amplifier with gain at minimum? How many at Maximum gain? I'm guessing that the amplifier doesn't have enough gain designed into it. But with those measurements made we will know for sure. Tony Definitely not user error. I swap out the JAD1200.1D for my old hifonics amp and follow the same procedure (instructions that came with the dd1) and it works, distortion light shows up. With the JAD the distortion light never lights up. Guess I would have to make a video
  6. All amplifiers should work on the DD-1. The blink while turning up the gain is caused by the DD-1's auto-range circuit shifting gears into the next range. The fact that the distortion LED doesn't illuminate even when the amplifier's gain control is all the way up would indicate the amplifier doesn't have enough gain designed into it. Amplifiers for automotive use should be able to reach clipping with 200mV of input and the gain control maxed. Tony
  7. Thank you guys for all the well wishes, I'm feeling better and haven't had any issues lately, thankfully! My heart went into A-fib the night of March 31 while I was asleep I guess? I woke up at about 4am to my 10 month old son crying and while helping the wife tend to him I noticed my heart felt like it was beating randomly. I asked her to feel my chest and she agreed. I went back to sleep until 7am and when I woke it was still doing it. I tried to take my blood pressure and the blood pres machine couldn't read me and just gave me errors. It always works so I knew something was up. I st
  8. The general spec for Bluetooth is 10 meters (33 feet) We do some special things with ours to be able to surpass this. We typically see 50 - 60 feet in our office with walls and stuff, outside in the parking lot we see about 100 feet. This is streaming from a iPhone 6S+ in my hand.
  9. A two way passive crossover as an example separates the low frequency audio and the high frequency audio. It does so by placing magic resistors in line with the tweeters and with the woofers. The magic is that these resistors change resistance (impedance) with frequency. For the tweeter we use a magic resistor that gets higher in impedance as the frequency decreases. At 10kHz this resistor might be 0 ohms, at 5kHz it might be 1 ohms, and at 2.5kHz it might be 4 ohms and at 1.25kHz it is 12 ohms, at 612Hz it is 48 ohms; and so on. If we are using a 4 ohm tweeter and the magic resistor hi
