    If you have thousands of dollars into your system, you might as well spend a little bit more to help get your settings right!! Originally, I set my mono by ear.. But when I used the DD-1, I was able to get even more out of the amp. Very easy to use and has instructions too

    I bought this tool to set my amplifier gains. It is super easy to use and I have to say my system sounds so much better. I can play it way louder and not have to worry about sending a bad signal threw my speakers/subs

    Awesome product!! Highly recommend it to anyone who cares about their equipment!! Im really good with doing this by ear but can’t beat dead on accuracy of this little device! Turns out I had a little more volume left on the head Unit and the sub amp.. As always super fast service and shipping!

    Works perfectly

    To be absolutely honest this thing feels like the thinnest cheapest piece of plastic I have held for 100+$ now that being said it works flawlessly and everything was perfect. Now my thoughts is to why it feels so cheap is it’s lightweight enough to hold as long as it takes to adjust the gains. All in all very satisfied with it does exactly what it was designed to do.
