I know it's hard to grasp the concept of distortion if there is no clipping. I will try to get some good pictures from my bench, showing the SMD DD-1 in action. For now, check out this picture of a distorted sine wave vs. a clean sine wave. Your little hand-held scope is not going to tell you about this, it may show it on the screen but unless you have robot eyes you aren't going to know what you are looking at. Hell, you have to look closely at those little LCD displays even to see clipping!

By the way, the blue is the distorted signal, red is clean.

me likey, me wanty

When using this to tune a sub amp, what 40hz tone do you want to use? Idk if you are supposed to use the 0db, -5db, or -15db?

id assume 0

hey steve i always end up running budget equip and i would like to know just how high i can go on the deck vol and the amp gain so ill be def getting one cause as a regular basis i have always just set at 2/3 gain and half bass boost and i really want to know how far off i am

im sure it will come with a CD that has the freqs on it, that you need to test with, so no need to worry about downloading them...

It also has instruction manual to inform you how to use it, so I'm sure they'll tell you which to use.

it all deals with the amount of gain overlap you want to have. Although the higher overlap, the usual more distortion you have as a consequence but gain DB.

here is what im trying to say:

so if ppl want to pre order it, how will they do it since the pre order thread is locked

OK... Sooooo... I got my meter in, unboxed it and went to work testing this thing... I made a quick vid but realized that Steve's address and phone # where on the box so I will make a new vid without that info hopefully today.

Regardless... I put it to work in a few cars.

First up, I read the owners manual (I suggest this as it does clear up a few questions I have heard on this forum)

Next I followed the instructions, found the output of her radio, then RE-TUNED her amplifier. I MUST say... the SMD DD1 performed very nicely. Her truck sounds amazing right now. I wanted to see what results if any would be reflected on the termlab so I popped it in the s10 for some comparisons (did some spl testing before retuning with the SMD DD1) The results surprised me. Her truck picked up .5dB!!! .5!!! Let me explain what that means... though you or I cannot HEAR the difference in .5dB... at the last show she would have gotten first place with that extra .5dB (she actually only lost by .2dB).

Next up... Mike's Avalanche... spl testing done before setting up with the SMD DD1.

Then max output of the radio along with a RETUNE of the amplifiers (mids/highs and sub amp) and gave it a quick listen then tested for spl... .6dB difference!!!!!! Not to mention his mids/highs are extremely loud at this point and sound absolutely amazing!

Then I retuned my soundboard making it sing even sweeter now...

I also retuned a couple of other simple setups and saw a few gains in spl (.3dB, .2dB, .3dB) but the biggest thing is how fast and easy it is to tune with the SMD DD1.

Great product and I hope to get a few vids up with some testing... we will be using the SMD DD1 to RETUNE the Boswell's DDBEAST, can't wait to see what happens...

Thanks again Steve.

Damn that means I would have gotten 2nd. This alone has me sold on one. When I get paid on the 15th I will be ordering it. Great Test Ric!
