  1. So we will be adding an AD-1 to our tool box at Driven Audio in Abbotsford BC! Once we have it setup I'll post that it's ready to use. Thinking of doing a food bank donation type thing for people who want to get their amps checked. No need to profit from it, but giving a little something to those who can use help isn't a bad thing I don't think Excited to get our hands on this beast and try it out!
  2. We've got the AD-1 Amp Dyno very close to production trim. Here are a couple of demo videos showing some of it's capabilities. Currently the AD-1 Amplifier Dyno is the only self contained test system that can measure RMS Continuous Power and Dynamic Power of both Full Range and Bandwidth Limited (subwoofer) Amplifiers in the world....and it does it in YOUR CAR! Please enjoy these two videos. The first video demonstrates the gain setting capability of the newly developed DD-1+ technology built into the AD-1. DD-1+ allow the user to make variable gain overlap settings in 1dB increments, even if the system is dirty and reads over 1% Distortion BEFORE clipping. The AD-1 amp dyno's DD-1+ technology can also be used in EXACTLY the same manner as the classic DD-1 if the user chooses. Link below The second video demonstrates the dyno loading and precision power measurement technologies in the AD-1 Amplifier Dyno. Learn about Certified Dyno Mode (which the Jeep's system failed due to headunit's noisy output), Uncertified Dyno Mode (which is the backup in the event you run into a problem like we did), and Dynamic Power Mode which measures power output during a very short term "bursted" signal. This is the industry standard for measuring "Dynamic Power" or "Headroom". Link below
  3. Tony Candela of CE Auto Electric Supply, Juan Rodriguez and I decided to do some testing with the AD-1 Amplifier Dyno to see what effects adding a capacitor to your system does. We did over 60 Dyno pulls with a Rockford T2500-1bdcp, without a capacitor, with a 1 Farad electrolytic capacitor (a real 1 F), and a 100 Farad carbon supercap. Test vehicle is a 2013 Jeep Grand Cherokee, 5.7 Hemi, 180 amp alternator, single group 49 AGM battery, all wiring 1/0 AWG copper. We tested each possible combination 3 times just to make sure our numbers were consistent, which they were. Video part 1 is continuous power testing, video 2 is dynamic burst power testing. Enjoy!!! Video part 1= Continuous power testing (uncertified dyno test mode). We do 4, 2 and 1 ohm dyno runs with no cap, 1 F cap, and 100 F cap. All tests in this video were made using the Uncertified Dyno Mode which is a continuous sine wave. We test a Rockford T2500-1bdcp in car, with no added capacitors, then with a 1 Farad aluminum electrolytic capacitor added, and then with a 100 Farad carbon supercapacitor added. RESULTS: No Capacitor: 1499 Watts RMS @ 13.07V into 4 ohms 2059 Watts RMS @ 11.84V into 2 ohms 2366 Watts RMS @ 10.83V into 1 ohm With 1 Farad Capacitor: 1489 Watts RMS @ 13.10V into 4 ohms 2024 Watts RMS @ 11.90V into 2 ohms 2358 Watts RMS @ 10.87V into 1 ohm With 100 Farad carbon supercapacitor: 1531 Watts RMS @ 13.13V into 4 ohms 2208 Watts RMS @ 12.25V into 2 ohms 2606 Watts RMS @ 11.30V into 1 ohm Engine RPM held between 2200-2500 for all tests. 1F capacitor didn't add any power on the continuous RMS test, actually lost a few watts probably due to the increased number of wire connections. 100F capacitor added more than 10% more power on the continuous RMS test Make sure to watch part 2, dynamic power testing (burst power). Hint: The results are different! --------------------------------------------------------------------------------------------------------------------------------------------------------- Video part 2= Dynamic burst testing (Dynamic Power Dyno Mode). We do 4, 2 and 1 ohm dyno runs with no cap, 1 F cap, and 100F cap. All tests in this video were made using the Dynamic Power (Burst) Dyno mode which is representative of musical peaks. We test a Rockford T2500-1bdcp in car, with no added capacitors, then with a 1 Farad aluminum electrolytic capacitor added, and then with a 100 Farad carbon supercapacitor added. RESULTS: No Capacitor: 1543 Watts RMS @ 13.80V into 4 ohms 2550 Watts RMS @ 13.32V into 2 ohms 3154 Watts RMS @ 12.76V into 1 ohm With 1 Farad Capacitor: 1613 Watts RMS @ 13.98V into 4 ohms 2666 Watts RMS @ 13.60V into 2 ohms 3426 Watts RMS @ 13.35V into 1 ohm With 100 Farad carbon supercapacitor: 1620 Watts RMS @ 13.95V into 4 ohms 2616 Watts RMS @ 13.65V into 2 ohms 3260 Watts RMS @ 12.91V into 1 ohm Engine RPM held between 2200-2500 for all tests. 1F capacitor didn't add any power on the continuous RMS test, but it OWNED the Dynamic Burst testing!! 100F capacitor added more than 10% more power on the continuous RMS test, but less than 5% on the dynamic burst test.
