  1. I have a DD-, I like it, and although I have only used it once to tune my system and have had it over a year I don't regret purchasing it. I am intrigued by the DD-1+ but am on the fence about making the purchase... $250. I asked about a trade in program when they first came out but I don't think there is one. Yeah I could sell my DD-1 but it's signed by Meade and I really don't want to try to sell it. I am not one of the lucky ones that can just drop hundreds of dollars on a new gadget whenever they want to. If I was in that position i would own all of the SMD tools and meters. I could buy it on credit but I am unemployed right now and that would be against my better judgement, although I could probably be convinced I watched Steve's YouTube video about the DD-1+, searched the forum for topics, and even downloaded the owners manual and am still left with questions about exactly how gain overlap compares to using the various DD-1 tracks. Say for example you have a DD-1+ and you set the gain overlap to 10db, how does that differ from just having the DD-1 and using the -10db track? Also, how do you know what type of overlap to use when you have fully variable adjustment from 0-15db? Thanks to any and all with input.
  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
