Get Rid of That Distortion

The purpose of the SMD DD-1 Distortion Detector/Analyzer by Steve Meade Designs is to enable the installer to set the gain of an audio amplifier to match the source units output level, accurately and quickly. It can also be useful for detecting distortion in the audio signal caused by poorly designed or malfunctioning audio equipment.

SMD has chosen a 9V battery as a power source for a few reasons. They are readily available and isolate the DD-1 from the vehicle’s electrical system for power, guaranteeing it will only measure what it is supposed to measure; the audio signal, not noise in the charging system. The supplied RCA connection is used to measure the output of a headunit directly, if you choose to do so. Should the harness become damaged it is easily replaceable or repairable in the field.


General Features:

  • Distortion Detector/Analyzer (Patent Pending)(DD1)
  • The Distortion Detector’s circuitry is 100% analog
  • Distortion Detection trigger level > 1.0% Harmonic Distortion
  • Guaranteed operating range of input signal is 1.2Vrms – 125Vrms. (15,000 Watts at 1 ohm) Autoranging
  • Signal Present LED trigger voltage 750mVrms
  • Low Battery LED trigger battery voltage < 5.6Vdc
  • Auto-shut off timer 8 - 10 minutes after ON button is pressed
  • For Systems running at 18 volts or higher check out the SMD DD-1 HV(High Voltage) Distortion Detector
  • To precisely calibrate your crossovers use the SMD CC-1 Crossover Calibrator by Steve Meade Designs
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Amazing Tool

November 23, 2013

This tool is by far the most impressive single purpose tool I have ever purchased. It's sole purpose is to detect distortion, Which it does at an amazing accuracy and with minimal user effort. I set the gains of both my DC3.5k mono and DC175.4 4Channel, in the underground parking of the local mall on my lunch break. This tool also can be perfect for finding your decks max undistorted volume, which is a bonus for any SQ oriented builder. All and all this unit is solid and well worth every single one of the 15,000 pennies you spend on it. A word of warning, although this is often confused as a gain setter. IT DETECTS DISTORTION. You can and will over power your speakers and blow coils if you just crank your amp to max undistorted levels without concern for your speakers power handling rating. a 150 watt channel will decimate a 35w coil with an undistorted signal! Just keep in mind this detects distortion and not your max output and you'll set gains like a pro. ** READ THE MANUAL, not only insanely easy to read and full of useful info. Meade actually managed to pack some humor into his manual..quality you just cant match from the mass producers.

does decent job

October 30, 2014

Sometimes when I use it, I can then the gain all the way up on the amp and the distortion light doesn't come on. Other times it will work correctly. Not sure what the problem is, but when it works, its fast and easy.

Dd-1 review

July 25, 2014

I purchased the smd dd-1 to set my amp gains on my system. I was do impressed with the increase and power and clean signal that it provided I decided to start setting amp gains for others on the side so that they can also experience how much better a properly tuned system sounds. This product is easy to use, compact, and has good build quality. I also bought the cc-1 to set my crossover points and match my amp gains but that's a post for another review. All in all this is the best money I have ever spent on car audio installation gear. Thanks Steve and Sonic Electronix!

There's nothing like it!

July 16, 2014

If you want an undistorted system where you know how loud you can turn it and blow anything up then you need a DD! It comforting to know that when I spin that skinny knob I know everything id tuned right and I have nothing to worry about.

Read the directions and watch the SMD videos on Youtube if your unsure how to use it.

DD-1 Distortion Detector

May 28, 2014

Had no issues.. Fast processing and delivery through Sonic.. Detector comes with easy to follow instructions.. My system sounds nice, and the detector seamed to work great.. Would definitely recommend.. A little pricey though.. Per the detector, I was fairly accurate matching mid and high amp gains by ear, but I was way off on my source unit and sub amp.. Really not even close.. Made the corrections, and my system sounds great now..

great tool but .....

May 11, 2014

I owned both the DD-1 and the SMD for a while and i really love them. simple, precise and easy to use. My problem is with the price. I think they are too expensive for a one dimensional tool that i don't use often. That's why i sold them and bought a scope for $400. It takes some learning to use, but it does the job of both the DD1 and SMD and much much more. I use my scope every week on my car and on my house.

Useful tool and quick

April 25, 2014

I've always set gains using a tpi440. I bought the DD-1 as I'd seen some verification videos of it being right on with the TPI, but looked much faster to use. Well used it quite a bit now and have to say it is quick and effective. Super simple to use and makes setting the gains correctly on your system easy and fast. One note. I watched videos on how to use this tool and then read the instructions when I received it. There is a change to the new tools when it comes to setting amp gains in that you hook the red probe to the + speaker terminal and the black probe to the - speaker terminal. All the videos I'd watched showed the black probe to amp ground. This has changed and I verified with Tony at the manufacturer before using. So, word to the wise, double check your instructions before using to make sure you have it hooked up right. Either way, an excellent tool and worth having.

Great product at an amazing value. Designed by Car Audio Leaders

March 28, 2014

This is an amazing product. I just found out about this product this year by stumbling upon it and its creators on Youtube. I watched all of the videos I could find and did a lot of research. This product is the result of a leader in car audio installation in southern Cali (Steve Meade) and an electrical engineer who has a long career in car audio (D'Amore Engineering). This is not a product that was created with all glitz/glam and no function. This was created with full function in mind by two titans in the car audio industry. It is extremely easy to use and gives you confidence in your amp settings.

Pros:
Ease of use
Style of product
Accuracy
Numerous testing options (speaker outputs or directly from RCA's)

Cons:
Only the price. But this is ONLY if you are looking to use the product only for personal use (ie. 1 or 2 vehicles). It's a good bit of money for just one or two vehicles, but peace-of-mind can also be priceless. But, rest assured, this product has had a lot of R&D and testing put into it before being produced. And, each product from D'Amore Engineering is specifically tested (by the maker) to verify the product works as stated. $150 is a lot for a single user and probably more suited for installers, but, like I said, peace-of-mind is priceless.

I HIGHLY recommend this product and recommend not just taking my word for it, but looking up the accomplishments of the creators on Youtube to learn more for yourself!

to tune all the amps i have. Some i also bought from you!
Anthony L on Sep 10, 2014
i have yet to be answered ,dose this tune all amps,including mids and or highs?
Dave D on Oct 17, 2014
Best Answer: Yes. The DD-1 will set the gains on any amplifier weather it's a bass amp, or a mids and highs amp. I have used it on both my amps which is the Crescendo bc5500d for the bass, and on my Rockford Fosgate 600.4 which is my mids and highs amp. It made a big difference in the sound. I have a Kenwood head unit and the max volume is 35. After using the DD-1 I can turn the volume to 33 with no distortion. Great product.

will this help tune an eq??
A shopper on Dec 16, 2014
Best Answer: This will help tune an EQ, but it depends on your setup a little.

The DD1 is great for getting maximum output from your individual components (headunit, EQ, amps) without distortion. If you follow the instructions in the manual, you start up from with the headunit and figure out its maximum, non-distorted output. Then you do the same for an EQ and your amplifiers.

For instance, I have the Clarion EQS746 and was able to use the DD1 to determine that I could have the volume up all the way on the EQ without distorting. Personally, however, I would rather not have my EQ working as hard as it can just to have the gains set lower on the amps, so I set the volume significantly lower and then proceeded to follow the DD1 manual for setting my amp gains.

When it comes to EQs, one thing to keep in mind is the output voltage for your RCAs. My EQ is able to put out 7 volts, but my JL amp only receives up to 4. Consequently, when I had my EQ outputting more than 4 volts, I wasn't able to turn up the gain at all on my JL amp because it read distortion immediately. Because of that, I had to use a voltmeter to set the volume/gain on my EQ to get just under 4 volts from my RCAs and then I was able to use the DD1 again and set my amp gains.

I hope this helps!
