Have you ever noticed that when you send a computer signal or an HD camera feed through the old coaxial cabling in your building that it looks bad? The color isn't accurate and the resolution is low. That's what happens when you take those high resolution signals and convert them to work with older RF modulators.

What's great about RF systems is that they can support multiple channels on one piece of cable, so anyone with the remote control can select from the a video feed, the security cameras, a childcare feed, an announcement video, a rolling activities feed from a computer, or anything else on the system.

RF modulation is a great way to create a low-cost distributed video system.  The problem is that RF modulators can't handle today's higher resolution computer and HD video signals, but the coaxial cable that connects those modulators to the TV's can.

I can almost hear you saying, "but the picture quality is so bad, especially the computer, that I think that we just need to scrap the whole thing and start over." Did you know that many cable TV systems use the same type of coaxial cable and a modulation process to deliver HDTV signals right to your home?

Before you rip out your old coaxial cable, consider this.

Sennheiser Launches Battle Against Counterfeiters [The Hartford Courant, Conn.]

Sennheiser Electronic Corp., a high-end audio maker based in Old Lyme, is trying to knock out scores of websites and vendors selling counterfeit versions of its popular headphones, with a blast of lawsuits.

In one case, a phony pair of Sennheiser headphones was purchased from an online website by the son of Sennheiser's president. When Jeremy Falcone complained to his father, company president John Falcone, "It was, 'Hey Dad, these Sennheiser headphones I bought sound horrible!'" Turns out the horrible-sounding headphones were counterfeit, John Falcone said.

Sennheiser, a German company whose U.S. headquarters are located in Old Lyme, CT filed a dozen federal lawsuits this week in U.S. District Court for the Central District of California. The lawsuits, which allege trademark infringement and other violations, identify more than 100 suspicious websites and dealers in the U.S. and China engaged in the sale of counterfeit Sennheiser-branded products.

As more pirate websites and dealers selling knockoffs are identified, "more lawsuits will be forthcoming," Falcone said Tuesday.

Most audio effects processors include a simple delay. Often, that effect gets overlooked because we typically reach for the plates, halls and other reverbs first. However, if you have the capability, adding some delay can create some very cool effects.

For this post, I will contain the suggestions to vocals only. Guitarists often add tap delays themselves, and putting some tap delay on drums can be really cool (when done well). But those will remain out of scope for the time being (play with those on your own).

There are tons of uses for delay; I will focus on two today--thickening and echo.
