So when you have it connected at amplifier you get signal and distortion LEDs, but no 1kHz or 40Hz LEDs?

So what happens when you leave the headunit connected to the amplifiers and measure with the included harness at the speaker connectors of amplifier and use a -10dB track?

Thanks for the clarification Tony, EXACTLY what I was looking for. Im sure you were debating whether or not to even entertain this nonsense so I appreciate you taking time to educate the dont knows.

Also, that little LED board in the video is made for 12V DC, likely having an appropriate reverse voltage blocking diode before the LEDs on the board as well some resistors for current limiting. Do not try to connect an LED by itself to your amplifier's outputs. Without a reverse voltage blocking diode and appropriate current limiting resistors or circuits you will destroy your LEDs.

Just a quick couple of notes: 1. LEDs operate on DC 2. There is no such thing as "an LED made for AC" per the yahoo explanation 3. His LEDs light up with AC from his amp because an LED is a DIODE... a Light Emitting Diode. = L.E.D. When you pass AC through a diode you get DC. This DC is what lights his LEDs 4. The Distortion Detector (DD-1) doesn't care about DC voltage. 5. Clipping is not DC voltage. Clipping is a when an AC voltage sine wave runs out of room to get any bigger and gets flattened off or "clipped" off at the top and bottom of the waveform, hence the name "clipping" 6. The Distortion Detector (DD-1) doesn't try to measure "clipping"

I think I just got dumber by reading this. Even that yahoo explanation has serious problems.

You could set the amplifier gain with the -0dB track. This will lower the average power output quite a bit.

Those line level converters are really starting to show their ugly heads with the DD-1. Some of them distort the low frequencies pretty bad. Someone needs to invent a proper one. Hmm

Here you go my good sir! I forgot to add that I checked the clip light with a friend's Oscope and that when I first got it - it worked just fine in my car. Now it does this no matter what. (I didn't drop it or anything. All my toys are treated quite well) Any updates? http://www.youtube.com/watch?v=txVwHiPnimA

Also try a -5 or -10dB track to see if the problem persists. What is your source unit? Are you using the supplied CD or has it been ripped?

Class D amplifiers are notorious for doing this, as well as messing up your radio reception and making garage door openers not work lol.

This is gonna be hella cool

This doesn't sound right, please send the unit to us as soon as possible. We will take care of it and get it right back to you. D'Amore Engineering 340 Paseo Camarillo #202 Camarillo, CA 93010

Did it get sent to us? Haven't seen it yet. Tony

We updated our site today with a revised DD-1 owner's manual, available for download. There were a few errors in previous versions. We've also added info on the up and coming CC-1. Check it out www.DAmoreEngineering.com

We updated our website today with the CC-1 prototype information and preliminary owner's manual (we know there are some typos). Check it out to learn more about the up and coming CC-1! DAmoreEngineering.com

Connect the DD-1 to headunit's RCA output. Make sure bass, treb, and eqs and crossovers are off. Play the 40Hz -0dB track. Turn the volume up until you see distortion and note the max volume of the headunit. Now leave headunit volume to max volume setting found from 1st step. Set epicenter effect level to where you think it will be used. Connect headunit output to epicenter input. Connect epicenter output to amplifier input. Connect DD-1 to amplifier speaker outputs. Turn amplifier crossover to highest frequency. Play 40Hz -10dB track. Adjust gain on amplifier until you see distortion, then back off a little until it's gone. Done. If you have problems with this let me know. The epicenter creates distortion to do what it does so it may or may not work. Please let me know!

Are you just setting your subwoofer amplifier, or are there full range amplifiers in your system too?

Its going to be a bit tricky with the epicenter for sure. I would follow the instructions in the DD-1 manual, leaving the epicenter effect level to the maximum level. Then after gains are set back the epicenter down. If when you are finished, it sounds like there is not enough gain, try the -15dB track.

Haha that's funny. It is supposed to say "pot" though, as in potentiometer. That would be the crossover knob.

I'd like to get the DD-1 back so we can run some tests on it. I want to make sure all the DD-1 owners are more than happy with their device. PM sent

Class D amplifiers put out some nasty %^&* when they are about to reach clipping, or during clipping. This is the noise you hear. Its not awesome, but it is what it is with Class D.

Ok, looking forward to your results.
