Essential Sound Products AVP-14: Oh, What A Difference An AC Cord Can Make
Don't dismiss the Essential Sound Products AVP-14 as a simple power cord. Mike Griffin demonstrates how such a common component regarded as an accessory can have such varied implications on your sound monitoring. Stock power cords may even be linked to conditions like ear fatigue.
Check out the video and surprise yourself at how interested you become in AC cords.
MIKE GRIFFIN: I'm going to play some rock, and we found -- What I found, because I'm new in the pro audio market, is that a lot of engineers complain about listening fatigue, okay? If you're mixing a lot of music and it's got a lot of high upper mid range, lower treble energy, that is irritating, the distortion. You'll hear what I'm talking about.

You feel, I mean what's going on in the mid range? Okay. Sam epassag, ESP cord

Now, we didn't change any EQ or anything like that. It may sound like we turned the frequency down, but what you're hearing now is the lack of distortion that's being generated in that upper mid range area, okay? Now, we're going to go back and forth just, you know , make sure you can hear the difference, and then we're going to go to the upper frequencies.

As we're switching back and forth, can you pick up the difference now? Okay, are there any questions? Okay. I'm going to do one more, and this is going to be more of the upper frequencies. I'm going to play Natalie Cole.

If you listened to the violins, I don't know if you noticed that. They sound more forward. With the stock cord, there's more emphasis. They actually have a more of a steely quality about them. It's more of a relaxed sound with the ESP cord and more depth and more air, more ambient information that you're able to hear because it's not being amassed by the distortion in the upper mid range area.
That's correct, and it's transients throughout the entire frequency range, and in addition, you know, we've had tested-- We've had tested independently with the shielding and with the design we have, we have about 6 dB broadband noise reduction of the cable itself, so in your front-end gear, you're going to have a lower noise floor, so you're going to get more signal-to-noise ratio as well. So between eliminating distortion and dropping the noise floor, you're going to get better recordings as well as we're listening to playback now.




but the microphone is
huh?
The speaker on your screen's
thank you
Everything is not 100% the
I'd love to do that (since I
