Essential Sound Products AVP-14: The Difference Of Clean AC Power
Mike Griffin of Essential Sound Products, maker of the AVP-14 power cord, goes to show that sometimes the most overlooked part of your setup - an AC power cord - can make a huge difference in the sound coming out of your speakers or the performance of your gear. To find out just what kind of difference it makes, you can hear it in this video. Make sure to listen for the much tighter bass sound when the AVP-14 powers up the monitors.
Stick around for more from Mike Griffin and Essential Sound Products - he promises the best guitar player you've ever heard. Which member of DragonForce will it be? Find out next time on Gearwire.
MIKE GRIFFIN: Come on in. Come on in. Take a seat. We're all going to have some fun, okay? Make yourself comfortable, huh? No. You -- I guarantee you that you won't fall asleep. You'll get a good demo and you'll get the best guitars you've ever heard in your life.
Okay. I'm not like these guys are here but okay, my name is Mike Griffin, and my company's Essential Sound Products, and we make AC power cords, and I consider myself a frustrated musician. I never learned how to play an instrument but I've always loved music, you know, since I was kid, and I worked for GM, I've been a design engineer all my career, and just by extension of my hobby, I invented a power cord that's designed from a clean sheet just for music, and what's unique about this cord, and this sample I'm going to pass around to you, is instead of having a single line of neutral conductor like most cords you have are lying on neutral ground, right? We have multiple line of neutral conductors, and that was very key to getting some of the problems inherent in power cords and design that out of the picture, okay? Beyond that, what's going on is you got an oversized ground, you have reinforcements so that this is not going to separate. In fact, I don't know if you can see the green dot, I'll pass this around, but it has hospital grade -- it meets hospital grade standards, which is extra physical abuse, okay? So if you, you know, gigging with this and you're setting up and tearing down all that, you don’t have to baby this, okay. This is going to last, okay?
So, let me pass this around and I'm going to tell you what we're going to do. There's a lot of skepticism, especially in pro audio. Our base is high-end audio. We've been doing this 1995 in high-end audio, and two years ago we decided to take our high-end product and make it into a completely mass produced UL-approved product that can be used wherever you use power cords, okay? So that's what we're going to be using on our demo, the AVP-14, of which a sample is going around is what's in the demo.
The first thing we're going to do is we have some Mackie Studio Monitors. This monitor has the standard stock power cord. This monitor has an ESP cord. And you know, the Mackies are very consistent so we felt like this would be a good way to demonstrate this product. We'll play some CD's for you that are going to feature different instruments and different frequency ranges so you can hear what's going on, okay? And what's going on, what's caused by the cords and what we got.
What we're doing is I'm feeding -- I'm going to feed a mono signal, so again the same signal, okay? We're going to play this one first, then we'll play this, and then we'll probably go back and kind of switch real time so you can.

Okay. Now the exact same thing through the speaker with the ESP power cord.

Now I'm going to replay them again. You know, you got a level set. I'm going to replay them again. I'm going to switch back and forth while it's playing, okay, so you can try to pick up the difference a little bit better.

The control, what's happening is that 18-gauge cord that's on those amps, it can't get the power to the amp to control the bass, so the bass is boomier sounding. With our cord, you still get the extension, the richness, but it helps the amp be able to tighten up and control the sound.
