Computer Stereo Speakers Making Static Noise

I am a physicist. (energy physics not matter physics). I am also a sound engineer, coincidentally, the control of sound energy. This amp is VERY GOOD for bench testing audio control devices and speakers. The addition of an unbalanced input makes it very handy for typical bench tests. Because I am retired I also use commercial speakers for my home stereo system. Use of commercial speakers is much cheaper than consumer speaker products that, by and large, do Not provide full range audio despite deceitful specs claiming otherwise. The commercial speaker is also built to last and far more reliable than consumer designs. (will last decades under home stereo use... my last amp lasted 31 years... speakers are still going strong) I use this amp as my home stereo amp driving 1,200 watt rated commercial speakers that actually reproduce 20Hz. (actual amp power use rarely exceeds 75 watts peak and 25 watts average) In that unique use... the amp fan noise is detectable so I place it behind a glass paneled cabinet. Aside from fan noise, the amp performs very well and for the price is one of the best bargains there is. Keep in mind... the typical consumer stereo amp is Designed To Fail and the primary reason is.... no active fan cooling. (a flawed design that minimizes ambient noise) The amp provides plenty of dynamic headroom (nearly 6dB under typical home stereo use) and presents no excessive noise floor problems. I use a receiver with balanced XLR outputs, a balanced 31 band EQ to drive the amp and control volume. My speaker connections are Speakon. Bottom line... A very good simple amp for multiple purposes at a very good price. If you are an engineer who loves music and movies you will quickly recognize the wisdom of putting up with a bit of fan noise to achieve excellent performance and very long term reliability.

I play all of my music CD's and MP3's on my desktop computer routing the line out signal from my sound card into a stereo system that has speakers in various locations in my home. There was always a low level hum while the computer was powered on when playing music, not too bad but not desirable. When the computer was powered off the hum would get much louder and the stereo system would need to be powered down or switched to a different input such as FM or phono to eliminate the noise. I tried several filters and even ground isolation circuits, no help. I determined the problem source was common mode noise, a difference between ground potentials of the two systems. I purchased the HE18 because of the size and superior audio specifications. Very easy to install giving me options for several different connector types, I used the RCA style connectors. Excellent results. Problem eliminated. I do not detect any frequency or volume loss.

I have an old stereo receiver which I use with a computer for tunes in my shop. A lot of noise and static was always being picked up by the cable, and rather than try shielded cables I decided to just utilize the optical output on the computer. Since the receiver didn't have optical capability, I picked up this converter to do the job. It does a great job, now there's no electrical connection to the computer and the noise is 100% gone.

I use this Y-cable for connecting two audio cords (from my desktop speakers) to my computer which only has one stereo output. It is great and I have not found any flaws. I will see how it will hold up in the long run.

I use this to switch computer sound card output between PC speakers and stereo amplifier. Works great.

100% improvement on the old set of computer speakers I had. These are bookcase stereo speaker quality sounding additions to your computer.

I was having difficulty understanding conversations with my stereo/powered woofer computer speakers so I thought a cheap pair of speakers might produce a brighter sound. I was right! These solved my problem and I can now hear voices much more clearly.

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.

It gets even those tough stations to come in full stereo without any static. Amazing little radio and very good price point.

this item provided the sound I was looking for to supplement my stereo speakers.
