12V Fan Speed Control Switch

[Connector] Excellent quality and gives you muiltiple powering options. It has on/off switch with LED light, 1 D-tap, 2- 12v, 1-8v and USB-A connections.

[25.00 W] this switch was a perfect upgrade for speed and poe ports

[1] Big fan of the two-way switch that allows you to either speak for a moment, or leave the feed on permanently.

[46.30 CFM] Great fan. So happy to have 4 pin so I can control with my bios fan pattern.

Great fan. So happy to have 4 pin so I can control with my bios fan pattern.

[Internal] .....The switch is great. No fan, well made, very low power, and it only gets mildly warm when fully loaded. unlike my Trendnet PoE Ethernet switch - which is also very good the GREENnet switch has a built in power supply.

[44.5 lb] 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.

[White] I added a 6 port volume control switch to use the amp in multiple rooms and outside

[1x HDMI 1.4a] yes i found this switch i nice and speed in changing between the input .it is better than my old one which i purchased for higher price.thank you

[Yes 1 RU] I have this 24 port switch in a living space so quiet operation was a key requirement. And it is silent, no fan. Unfortunately, that ruled out using their POE version of this switch. For my POE needs, I added a Unifi 8 port POE switch which also has no fan and is silent. I have multiple Unifi switches that I manage. They are easy to install and configure.
