- In this video we bench test a D'Amore Engineering E1500.1 Car Audio Amplifier. Tested S/N Ratio, THD+N, Frequency Response, Infrasonic Filter, and maximum clean continuous sine wave power output (Watts RMS) into 3 different impedances. Bonus: Rant about the word "Subsonic"
Tony ,... send me one. So dope. Good shit dude.
Great content! I used the APx audio analyzer almost daily when I was designing OEM audio and infotainment products some years ago. It was an upgrade from the older AP System II and HP analyzers. I’d like to chat with you about some novel concepts for aftermarket car stereo amplifiers, if you have any interest. Keep up with the great content.
We are still waiting for a home audio amplifier.
If we introduced just 2 models, what power level and how many channels would you like to see?
Hes already done that
Do you happen to have the efficiency on the E1500.1? Especially ar 1 ohm.
You should do a video on the bdcp and what made it special
The constant power theory is for convenience..any amp that doesnt follow ohms law is incorrect thinking..tonys class ab amps he designed doubles output as imp is 1/2 d.. im not gonna talk bad about current limiting....WELL..I JUST DID.. TONY .. thats the test..compare an amp that has correct ability compared to ones with current secondary monitoring and voltage correction..and how they act on a real transducer compared to a resistive load..this will be fun to watch..by the way..didnt you develope the rockford cube plotting? And prove this? Funny how rockford changed their mind and designed the bdcp..haha..
Video is titled 1000.1 👌
Great video
Tony why is THD+N measured at a certain frequency with a certain frequency instead of white or pink noise?
By the way you miss labels the amp on this video.
Good question! Distortion is anything that is different between the input signal and the amplified output signal. White noise or Pink noise is random. Therefore there is no way to predict what the signal is going to look like, this makes it difficult to compare to the output. Not impossible, but not the way it is typically done. Good looking out on the typo, fixed.
why did you do those last runs uncertified to clipping.?lol
The dyno is set to uncertified just by chance, it wouldn't matter what I had the dyno set to during these tests because I'm not using the dyno to read power, only using it as a load. The Audio Precision is doing all of the measuring. It increases the signal until the amplifier reaches a level of distortion that is set by the user. In my testing I have it set to 1.0%, so it is exactly how the AD-1 dyno works in Certified Mode.
