DTECH Powered 4 Way 3 RCA Splitter Box 1 in 4 Out Composite Video Audio Distribution Duplicator with Power Adapter

I'm using the DTECH 4 Way Distribution Amp for Audio only, so I can't comment on the Video quality (in fact I'm only using 2 of the 4 Audio Outputs). It's a simple device and I really like the fact that there is no remote control or switching function, all 4 outputs are just "always on" !The Audio quality seems more than adequate for my Analog "Home Theater" system (no noise and no problems with frequency response). My video is HDMI into my Smart TV, so I have no need for the Video function.As at least one other reviewer mentioned, the Red power LED is VERY bright ! (It was bright enough to be annoying and I was able to "fix" this problem fairly easily...read below if you're interested in that, as well as some other technical observations).The unit is very well constructed, and it's easy to open up (4 screws to remove the cover). Note: I removed the 6 screws on the rear panel so I could look at the bottom side of the circuit board, but there are NO Components on the bottom side. Nothing to see here !I clipped one of the leads on the LED and inserted a resistor (I chose the value with the assistance of a resistor substitution box). I chose 33K ohm but any value between 10K and 33K should dim the overly bright LED to a reasonable level.Other observations:>The 9VDC power supply was right on @9.0VDC. Polarity is Center +, which is marked on the supply itself, but NOT on the case, so I labeled the rear of the case accordingly (important if the supply is ever replaced).>There are 11 electrolytic capacitors, which are all rated at 16VDC. As this is a fairly inexpensive device, I was expecting 10VDC rated caps, so this was a pleasant surprise.>No Integrated Circuits, just 8 small surface mount transistors, 4 of which are buffer/drivers for the 4 Video outputs. Two of the remaining 4 transistors appear to be for buffering the Audio L/R input signals. As I did not trace out the entire circuit, I'm guessing the other 2 transistors are probably either common drivers for all 8 (L/R) Audio Outputs, or, buffers for the video input ???>There does not appear to be any reverse polarity protection on the power supply input (nor any OverVoltage or OverCurrent protection). I guess I shouldn't expect that at this price point ? In any case, make sure any replacement power supplies have the correct voltage rating and polarity. Hopefully I won't have any problems due to a faulty power supply or voltage spikes 😏All in all, at this price, I'm happy with my purchse !

excellent!

This DTECH 1 in/4 out splitter was easy to connect and works as it should. This is a replacement for a different brand of what looks like a near identical product. The difference with this one is that it works with no noticeable audio or visual interference. The last one I bought with a different brand/seller (and plan to return) had a loud audio hum when the input was connected. This one works fine. The interesting thing is that the prior splitter box appeared to be slightly better constructed (has nice feet and a more easily manipulated power cable) yet this DTECH box works much better. I compared the technical specs of both boxes and they are the same. I took one star off because it does not have feet on it to balance it thus it tips a little but this does not hamper performance. Also, the red power light is rather bright but I was able to stick it behind the tv so it's not noticeable. I am happy with this product and would buy this product again. Also of note, the video actually seems to be clearer going through this box than straight to the tv. I don't think there is any amplification so I can't explain that but it looks and sounds very good.

I purchased this sweet little box for the purpose of connecting two stereo amplifiers to one audio output module which I have connected directly to my PC. It is a small Audio Box with only one set of RCA jacks for just one amp, which is the setup I have run for years. I wanted a richer sound without going with surround, and I had two great old tower speakers which I wanted to add to the mix.It would overload my single Denon amp if I were to try driving all four speakers with that amp alone by using speakers A and B on the back of the amp. Instead, I bought this fantastic little audio splitter for a very reasonable price indeed. I wasn't sure if I was going to end up with some hiss or some other noise introduced into my sound, or at least a noticeable signal loss. Remarkably, I have neither. While I am not a true audiophile, I have an excellent set of ears and the ability to discern quite subtle differences in sound. The inclusion of this wonderful box in my hookups did not negatively affect my sound quality in any noticeable way at all.The bottom line is that I am exceedingly pleased and somewhat surprised at how terrific this splitter really is. With one simple addition to my setup, I am now running two stereo amps off of the output of one PC audio box that had only one output. I am able to enjoy all four of my speakers, and ALL of my music listening, as well as movie watching, etc.,. has been hugely enhanced. And, I'm getting use out of this really cool old Sharp amplifier (one of the two running simultaneously), which, after hitting it's volume control with "De-Oxit", sounds like brand new. All made possible by getting this sweet little audio splitter box which actually delivers perfect sound! Buy it now!!!

I was able to hook up a couple pieces of equipment with it. Just what I needed.
