S1E4 D'Amore Engineering Bench Testing E1500.1 Car Audio Amplifier

[@soundman2604]

We are still waiting for a home audio amplifier.

[@DAmoreEngineering]

If we introduced just 2 models, what power level and how many channels would you like to see?

[@davidstevens7809]

Hes already done that

[@96kylar]

Tony ,... send me one. So dope. Good shit dude.

[@MichaelSmith-bu4kj]

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.

Video is titled 1000.1 👌

[@eliseoquiroz8321]

Do you happen to have the efficiency on the E1500.1? Especially ar 1 ohm.

[@panamaldat]

What is the input voltage for gain matching?

[@funnytoe]

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.

[@DAmoreEngineering]

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.

[@RealityUnmasked209]

why did you do those last runs uncertified to clipping.?lol

[@DAmoreEngineering]

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.
