External Computer Speakers Making Noise

I've owned this Mac Pro for over two years now, and in that time have been consistently pleased with its performance. I use it predominantly for compiling and editing photographs via Lightroom and Photoshop, as well as holding my iTunes library. For those purposes the computer is very quick and efficient. Its six thunderbolt 2 connections are exceptionally fast; I use all six to connect both the monitors and external hard drive arrays (see photo). I do wish it offered more than four USB 3.0 connectors, but that is a situation easily rectified with an external USB hub. In two years of continuous use I have yet to experience a problem with the machine. The computer is quite diminutive, making it easy to place in my office. And, it's sleek Darth Vader Trash Can look is appealing and attractive. Unfortunately, the one drawback of its size is that internal upgrades are impossible. You are extremely limited in the amount of storage you can have inside the computer (4TB). Therefore, external hard drive arrays are the only solution to those who need significantly more storage capacity, making the area needed for the computer and peripherals significantly larger. That minor issue aside, this is the best all around desktop computer I've owned, which is saying something. For photographers, you won't find a faster, more reliable product.

I needed an external volume control for my KRK Rokit speakers I purchased for a computer desktop setup. The PMC-II is� working great! I even had some questions about the product and Senal's computer service was top notch, I would not hesitate to buy another one if ever needed.

A passive a/b switch. I use it to be able to use one set of computer speakers with 2 different PC towers. It does not and any noise to the signal. Highly recommended and easy to connect.

Value for money together with a port for external speakers.

I am using this cable to connect my computer with speakers.

Connects my Mac Mini headphone out to external speakers.

Just what I needed to connect some external speakers for my television.

This 2.1 system by far is the best set-up I have ever owned from Logitech. Speakers are crisp and clean, lows are low and highs or high. I use these while gaming, as my PA speakers when I'm making my style of music(electro house) on FLStudio and mixing while using my DJ Pioneer DDJ-800 controller. Thanks Logitech for making such a fine product, and never discontinue these great speakers. Thanks
