## Overview

The Rolls MX51S Mini Mix 2 is a compact, powered 4-channel stereo mixer featuring one XLR mic input and three RCA stereo inputs, each with independent volume control. It delivers clean, amplified output via RCA or 1/8” jacks, housed in a rugged metal case. Ideal for professionals and enthusiasts needing versatile, simultaneous multi-source mixing in a space-saving design.

## Description

The MX51S mini mix 2 is small four-channel mixer with individual volume controls, and a headphone/ line output. The unit has one XLR input along with an 1/8” input and 3 sets of stereo RCA inputs. It has enough gain and output level to connect to a power amplifier, with either RCA or 1/8” jacks. The MX51S is powered by an included rolls PS27 12 VDC adapter.

Review: Excellent quality, compact, powered mixer serves my needs perfectly - While upgrading my gaming/AV setup, I ran into various audio issues that, after many purchases, tests, returns, and cables plugged in and unplugged, eventually boiled down to me having 2 analog audio signals that needed to feed into a single analog input on my speaker system and be able to play simultaneously. Now, the cheap and dirty way to handle this is to grab a $5 headphone splitter and hook it up backwards. However, because a headphone splitter is not powered, this will attenuate the signal strength from both sources, and can even cause hardware failures if there is a spike or surge. I'm not an electrical circuits expert so I will let you research that kind of thing yourself, but the bottom line is that a powered mixer is the best way to get 2 independent signals to feed into a single input without losing strength (a switcher would be a simpler option if you don't need both sources to play audio simultaneously). This Rolls MX51S proved to be exactly what I needed: A compact powered mixer with independent volume controls, RCA output, and at least 2 RCA inputs. This mixer actually has 4 inputs, but one is XLR mono for a microphone. The mixer has a very quality construction with a powder coated metal case, solidly attached input and output jacks, and very nice potentiometer knobs with a detent at the 12:00 (gain = 1) position. The mixer actually provides a mild amplifier capability if you turn the knobs past 12:00, but some people report clipping at max gain. This is hardly a drawback, as a unit this small with mixing capabilities really isn't meant to be used as a serious amp. I just set my overall system volume loud enough that a gain of 1 is more than I will ever need, and I keep the input volumes turned down. The mixer works excellently. I can play both sources at the same time with fully independent volume control, something that I didn't have in my system prior to my upgrades, so even though I hadn't originally planned to use a mixer with my setup, I am very glad that it eventually became necessary, because I now have much greater versatility. The mixer is very compact and fits nicely off to the side in one of the shelves of my AV cabinet. Many other mixers are much larger and although they probably work well too, I don't have the space or need for that kind of thing. I did run into one interesting issue while using this mixer. Both sources that I have fed into it are analog signals from DAC's. I went through 5 different DAC's before getting a setup that actually worked correctly all the time. One of them, an Insignia purchased from Best Buy, started causing loud popping and clicking to come out of my speakers after the optical source was turned off...but only when it was connected to this mixer. If I plugged it directly into my sound system, bypassing/disconnecting the mixer, it was fine. HOWEVER, with the DAC's I eventually settled on (one a FiiO D3 and one an eSYNiC), this problem does not occur at all, so I'm guessing that some combination of poor grounding and signal interference created a "perfect storm" between the Insignia and the Rolls mixer. In any case, the issue no longer occurs, and I don't think the mixer is to blame at all. Overall, I am very impressed and pleased with the mixer. It does exactly what I need, does it very well, and all for a bargain price.
Review: Works perfect for my PC and Game Console audio to Headphone setup (Listen to both at the same time!) - If you're looking for a quality, compact stereo mixer to combine multiple audio sources and output to a single pair of headphones or speakers, this device works perfectly. Measuring roughly 5 inches by 3 inches, its construction is solid and surprisingly made in the USA. All of the ports feature a nice and tight fit and the knobs are silky smooth. It's powered by a power adapter which is included. It has four separate channel inputs and two output options. Channel 1 is an XLR input with phantom power option (which you can turn on/off). Channel 2 input is via RCA or 3.5mm. Channels 3 and 4's input are RCA. Output is via RCA or 3.5mm. There are more than enough ways you can set this up depending on your devices and needs. If you need to use 3.5mm, either as an input or output, you can simply buy a 3.5mm to RCA cable adapter. Some reviews complain about static, hissing, or lowered volume; I have not encountered any of these issues under normal use. As long as you are using quality cables and your source output devices aren't cheap, no audio issues should be encountered. I can easily control each channel's volume independently with no loss in audio quality. Turning the knob all the way down will completely mute the source and turning it up has more than ample volume (although this may vary a bit depending on the quality of your output device). The only actual hissing I can hear (using headphones) is when you get near max volume on the knob when all other channels are silent. At the volumes you encounter the hissing at, you would blow your eardrums out. Under normal use, you don't hear it at all. There are obviously several ways you can hook this up. For reference, I am using it to connect the audio from my PC and the audio from my game consoles (PS4 and Switch) and have it all output to my headphones. In my case, the game consoles are hooked up to a Denon A/V receiver and I am using the headphone output from it to connect to the stereo mixer. For the PC audio, I am simply using the front 3.5mm output and have it connected to the stereo mixer. From the stereo mixer, I have the output audio plug into an external headphone amplifier which then finally outputs it to my headphones. My headphone amplifier definitely helps with overall volume, but even without it, the stereo mixer has plenty of power to output enough volume even to my higher ohm headphones from Sennheiser and AKG. Even hitting about halfway on the knob gets too loud and about a quarter of the way is good enough for normal use. With this particular setup, I can now get game sounds and if needed, I can stream music from my PC at the same time. Or I can use voice chat on the PC instead of using Playstation's party chat or the Nintendo Switch's currently horrible (non-existent) chat system. And of course if I just want one audio source, then I can simply turn down the knob on the stereo mixer to mute it completely. All in all, this is an excellent compact stereo mixer which makes life easier if you have a setup requiring multiple audio sources outputting to a single headphone/speaker setup at the same time. It works well as somewhat of an audio switcher as well without actually having to switch inputs or cables around. If this sounds like what you need, I wouldn't hesitate to recommend this product.

## Questions & Answers

**Q: Description: "It has 2 1/4" inputs and 3 sets of stereo RCA inputs that are mixed to MONO." Are the L and R inputs really mixed together?**
A: apparently Amazon confused the description. There is a Rolls MX51 and a Rolls MX51s. The non-s has 1/4" inputs and mixes to mono. The "s" model had 1/8" input and XLR input and mixes stereo.

**Q: Are others having problems with hum or ground noise on channel 1 when using condenser microphones with phantom power?**
A: I Just Bought this device and powered it up adn the Hum/Ground noise Happens even without the condenser microphone switch off or ON, with or WITHOUT the microphone plugged in.

**Q: Can it be used to have two audio devices connected to one set of speakers? If so, will they be able to play at the same time?**
A: Yes. That is exactly why I purchased this device. It mixes four sources to one output. If you just have passive speakers, you will need amplifier, but probably your "set of speakers" does include amplifier.

**Q: Hey guys does this come with an a/c adapter? That one dude in the reviews said his did not.**
A: Mine certainly did come with AC adapter. It can not function without. It’s a great device. I wish it had an on/off switch. I unplug the power cord from the rear of the unit as the AC adapter is plugged into a Monster voltage protector with the other audio gear so to me it’s just easier this way.

### ⭐⭐⭐⭐⭐ Excellent little mixer
*by J***N on December 24, 2019*

I was setting up a small PA system for a fellowship hall area in our church and I wanted to combine the line inputs from the cordless microphone receiver and the audio from a television. This mixer is exactly what I needed to join these two signals into a single input on the amplifier. Previously the microphone signal went to the RCA inputs of one amplifier input while the TV audio went into the RCA inputs of a different amplifier input. Only one or the other could be input at a time, so a presenter who had a video with sound to show on the TV (through the HDMI TV input) had to switch the amplifier input from the microphone to the TV to show the video with sound through the PA into the room. Now they can start and stop the video without switching and can even add their own comments with the microphones while the video is showing. Among the possibilities is that we can have Karaoke in the room which several people are thinking about. The mixer is solidly built and it was easy to set the two volume levels for our inputs. The mixer operates very cleanly without noise when adjusting the volume levels. I appreciate that there are still two inputs available after using the RCA inputs on channel 3 & 4 for the microphone and TV audio. Channel 2 has either RCA input or 1/8" stereo input, so it is a logical choice to use for an iPod input at some point. Channel 1 only has an XLR input with switchable phantom power so we could use that for a wired microphone at some time if we want. It would be a very useful input for a DJ arrangement (maybe for a Karaoke night?) although we aren't using it at this time.
