If you read the other questions, the connection is explained. Any 4 RCA sources to one Amp or reversed such as single CD player to 4 different amps. **Q: Will this work for car audio?** A: I don't see why it wouldn't. **Q: What is the maximum recommended cable length for the output, since it is passive?** A: That’s hard to tell. Depends on your cable and your tolerance of signal degradation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little gem punching way above its weight class! *by on Reviewed in the United States March 20, 2026* Wow that’s all I can say. I been looking for one of these for a while now but the ones I wanted were quite expensive then I came across this one and took a chance. I am not disappointed I am actually pleasantly surprised. One it looks really good and is well made Has descent weight to it and the chassis is all aluminum. I hooked this up several ways from dac to 4 amps, amp to 4 dacs, amp to dac,cd player, etc.., and this little thing just performed flawlessly. Most importantly it did not alter the sound in any way it did not introduce any unwanted noise, hum, nothing of a sort it’s dead quiet. As for the rca input and out puts they were fine no complaints, I tried Audioquest (2x types), morrow audio,wire world, zavfino, etc…. And all the cables plugged in as they should not loose or to tight they were just right. This is an excellent product well worth it and Iwill be purchasing another one it’s a must have. ### ⭐⭐⭐⭐⭐ Little did I expect this - but wow!!! *by on Reviewed in the United States May 18, 2020* Let's face it, when in the market for RCA cable switchers, one usually finds a variety of cheaper made models and it's not unusual to see the same model being marketed under different brands. This is often par for the course with these inexpensive Chinese branded models.In my case, I have 6 different DAC's that I use with my desktop PC, attached to a variety of speakers. Yes, I do online reviews and provide comments regarding performance characteristics of different pieces of equipment.So last week I began to look for a good 4-unit RCA Audio cable switcher. And mannnn, there were tons of them on Amazon - most were very cheap in price, while a few ranged between $100 and $200 USD. I was eventually eyeing one that cost close to $200, when I happened upon this GOHIFIAUDIO S1 switcher.I thought, "Hmnnnn, they want $70 USD for this thing (at the time of this writing - they've gone up since then)?" I was hesitant at first, mainly because it had no reviews, and also the thought (assumption) that any type of cable switcher will result in signal loss - especially with passive models (of which this model S1 is one). But being the guinea pig that I tend to be, I pulled the trigger and purchased it.When it arrived, I noticed that the box seemed heavy (a bit more than I expected). When I opened the box, I was dumbfounded (in a very, very good way) to see a solid brick of a switcher. Beautifully machined and exceptionally solid (thus the weight of the unit), you could see that this was not going to be no ordinary every-day switcher. The RCA inputs on the back were meticulously designed and constructed and durable and you knew right away that you were dealing with a higher end device.But how would it sound? I immediately connected several DAC's to this unit. By the way, for those not familiar with the term "DAC," it's short for Digital to Analog Converter which can make a world of difference with sound quality on the likes of a PC or a video system. When I selected switch #1 - which happened to have the iFI Zen DAC unit, I could not believe my ears. No signal loss or alteration at all - what you listened to is what you got. And the switching back and forth (between 4 units) is so smooth and high-end, that it will put a smile on your face. And no worrying about using the right power supply as this is a very basic passive unit, that was exceptionally crafted/machined. The moment you handle (pick up) and use this Model S1, you'll be hooked and then wonder why you haven't seen this thing before.So right now I have the following DAC's attached to this GOHIFIAUDIO S1 - those being the iFI Zen DAC, the Schliit Modi 3, the Micca OriGen2, the FX Audio DAC X6, and the Sabaj D3. Switching between them to do a budget DAC audio evaluation was effortless.Another question that folks often have with regards to the possibility of using an RCA audio switcher, is will thick cables (and bending them to connect to other units) result in the switcher being lifted up, or turned in a particular direction. This happens big time with thicker, less pliable cables. I can tell you that in my case, I have each DAC connected to the S1 switcher with a shorter 1 foot RCA cable and the only result was that the smaller DAC's had to be turned somewhat - but the S1 switcher was solid and stayed put!So folks, I'm just one reviewer, but my listening standards are high. I'm gratified to have found this particular Switcher on Amazon. This comes highly recommended! Caveat here - remember, reviews are subjective and all I can do being an audiophile is to call 'em as I see 'em. YMMV.....EDIT - Add-on comments as of 6-29-2020:I just wanted to add on here that I purchased a 2nd switcher due to the fact that the first one was so awesome. I have additional components (i.e. DAC's) that I needed to bring into my system, so I got another one. I'm telling you, this passive model is built quite well and just plain works - without any signal loss or alterations!!!!Since I purchased the first GOHIFIAUDIO S1, I also tried another switcher that was not passive - it had to use a power supply. It was a Chinese made product also, but it failed after two weeks (the right channel stopped working on the 2nd set of RCA inputs). So I had to return that one. That made me realize that you stick with what works best, and that's why I purchased another GOHIFIAUDO S1. The GOHIFIAUDIO S1 sets the standard in my book.And yes, I know it went up in price - like some $20 more - but hey, it is most certainly worth it as you get what you pay for. ### ⭐⭐⭐⭐⭐ So far works great, does not affect sound quality *by on Reviewed in the United States May 14, 2026* So far so good. Does what it's supposed to do, does not affect sound quality. Seems like a quality built product. ## Frequently Bought Together - SOLUPEAK U31 Premium RCA Switch Box, 3 in 1 Out Audio Switch, Stereo Switch Box with Signal Lossless, Sturdy Aluminum case Strong Anti-Interference, Compact Connector Distributor RCA Splitter Boxes - Amazon Basics 2 RCA Audio Cable for Amplifier,Active Speakers or Subwoofer with Gold-Plated Plugs, 4 Feet, Black - Monoprice 1.5ft Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/222825463-3-in-1-out-audio-switch-stereo-switch-box](https://www.desertcart.uy/products/222825463-3-in-1-out-audio-switch-stereo-switch-box) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-06-09*
