      Don't let the small size fool you. The Rolls MX42 Mini Stereo Mixer has a solid metal build. The volume control knobs are quiet with a nice mechanical resistance and good "feel". I use the MX42 with a Behringer UCA202 Analog to Digital Converter. This is a passive mixer without any electronic enhancement. With the volume maxed-out the MX42 will attenuate the signal by 16dB. This may be a problem if you are using these with earphones and a portable source. I need to attenuate the signal from my phono preamp when I convert my LPs to digital so it's not a problem for me. The photo explains how I use this mixer.

      Product used to connect multiple line inputs into computer speakers.Tried using various cables with it (RCA) and one side would constantly be distorted (too much bass) - I understand it is a -12dB output however it is not just lowered but fully distorted versus the other outputting normally. Also experimented with the same original source and no mixer - perfect output.

          Comments about Rolls MX42 Mini Stereo Mixer:

          Rolls is quickly becoming a favorite of mine. Everything these guys make is built like a tank.

          I bought this mini mixer to sub-mix 4 pieces of stereo gear into 2 channels on my Yamaha 01v board,

          - Korg KP3 Kaoss Pad
          - Korg Kaossilator
          - Yamaha Tenori-On
          - Next DJS-24 Sample Player

          This device works beautifully and saves me 6 inputs in the process. The passive design makes this device space saving and simple to add to any setup (no wall wart!).

          The stated specs are a bit confusing... it says it attenuates by -12dB but that is a bit misleading... it goes to infinity no problem.

          Sits on my Yamaha keyboard with some two sided tape.

          I love it. Will deffinatly buy more products from Rolls. If you have a project studio, check out their Hum Eliminator too, its very good.

            I was looking for a product to passively mix multiple stereo devices into one output. This device does exactly that, and is fantastic in construction and performance.

                I use this to connect my computer, tv, and game console audio to my awesome speakers. I love how it is so compact and easy to use. The only bad thing I could possibly say is that it sometimes gets hidden on my desk because it is so small.

                      This little peice is the answer to the broplem of pulling out the 1/8th in jack from your coputer and having that loud pop that is annoying and can blow your speakers,you can also connect 4 ins so that you can mix between all your players or your friends computers etc..dope little guyand it's passive so you don't need to plug it in to power

                            Used to mixed audio signal from a matrox MXO mini and the computer's soundcard, then output to a pair of active monitor speakers. Works really well.

                              It's a four-channel, stereo mixer. Since it's passive, you can't amplify a signal with it, and it has no EQ's and no mic pre's, etc., so it's no suitable for any use except sub-mixing a bunch of stereo line-level signals. But if you have multiple synths or sound modules, and you record everything inside your PC, this will let you hear them all together without gobbling up a power outlet, or a rack space, and the passive nature of the mixer means that you're not compromising your signal quality with cheap op-amps or line noise. Simple, effective, I like it.

                                      I use the MX42 mixer to route my CD player, mini-disk, audio tuner and recorded mix from my DAW through the RCA tape inputs on my home studio mixer. Perfect for freeing up the 1/4" inputs on my mixer. Only complaint, it is small and if you hook up all four inputs it will most likely not stay on its feet. Not a big issue...

                                      I'd take a star in lieu of my own ignorance but that seems inappropriate. This device does exactly what it says it does so I can't take stars for that.

                                      However, I can't really think of a situation where losing 12db of signal is good, acceptable yes, but not good. For example, I can compensate for for the signal loss by connecting the output to an amplifier and adjust the volume from there. But mixing a bunch of devices from their 1/8" headphone outputs and trying to listen with headphones or record using PC's 1/8" line-in would be unacceptable.

                                      I'm tempted to try and breadboard a simple stereo amplifier circuit with the gain set to a static +12db so I can use the mixer with my headphones or PC's line-in without the use of more equipment.

                                      This was probably the wrong mixer for me but it performs the way it was intended to and it's construction is pretty solid ... so 5 stars.

                                        This little mixer is a dandy. I use it to combine 2 computers (a Mac and a Windows box) and an XM radio receiver. It's passive, works great with line-level signals, and of course, is super-quiet. It's very well built - all metal - no cheap plastic, here. I would definitely recommend it. The price may seem a bit high for a passive mixer, but considering the quality, it's worth it. I really have nothing "negative" to say. I did have to buy some 3.5mm-to-RCA adapter cables to match my computer audio outputs to the mixer, but these are inexpensive (less than $3 apiece).

                                          I use this mixer to combine audio output from 2 CD changers, an MP3 player, and a PC so that all of these components can be heard through one stereo receiver auxilliary input. That way I never have to plug/unplug components. Works great, is compact in size, well built, and doesn't require another external power supply.

                                                I've been looking for a 4 channel stereo mixer to go with my 4 port computer (KVM) switch and single set of powered speakers. Having the ability to hear the speaker output of any/all of the computers without switching between them is very helpful. This product does an excellent job!

                                                  I have my computer, TV, and iPod dock all connected to the same loudspeakers... but I wanted to hear alerts from the computer even if we were listening to one of the other sources. Problem solved. This little box is built like a tank, completely passive (who wants yet another "wall wart" power supply to plug in?), and mixes four stereo inputs with no degradation in sound quality. The only problem is that the box looks a bit clunky and is so small that it can actually be dragged off the shelf by the weight of the attached audio cables.
