X31 XLR Balanced Cable Switch Signal Sources selector 3 in 1 Out Audio switcher Splitter Box

I needed a device that would let me swap one set of my studio monitors' inputs to a "courtesy pair" of XLRs for when students or clients come over with their laptops/interfaces. Normally I'd have to dig around behind my studio desk to manually swap out cables but with this switcher box it is as simple as turning the knob. There are no pops or noises when turning the knob and the device does not add any noise or degrade the signal in any way. It simply works as it should and does its job without being noticeable in any way, which is exactly what I needed. I keep the middle "B" position unused as a way to have an instant "emergency off" should something ever go awry. One thing other buyers have mentioned is the loose knob. Mine did get loose at first but there is an Allen set screw (most likely metric?) that can be tightened as needed and this easily solved the problem. Just loosen the set screw, line up the arrow to the appropriate A/B/C and snug it up. Easy. The factory that makes these likely has a certain torque limit on that set screw when assembling and to me this is a complete non-issue as I have tons of Allen wrenches on hand.

Simple switch that works well, made well and looks good.

I got this to go in front of my audio interface so I can leave all of my instruments plugged in and just switch between them when inspiration (or lack there off) is striking. I have my bass rig plugged into the ”B” position obviously, guitar rig (stereo) on both sides of “C”, I use “A” for mics and mixers and such. It works as designed and is very quiet. The problem I had is with the knob. The knob has an Allen set screw that wouldn’t grab on the round shaft after tightening. I fixed this however. I filed a flat spot onto the shaft where the screw goes and all better. You will get pops when switching but I am sure that has to due with sudden changes in impedance. That is to be expected. Be smart.

I had been searching for a passive switch for two microphones to be able to switch between two mixer channels without constantly unplugging/plugging cables, since I have a voice synthesizer/harmonizer on one channel, but I could not find such a switch (these are typically called a cross switch or Aa-Bb-Ab-Ba). This box worked perfectly for that purpose after I added some wiring.One downside - It is cheaply made and the screw "ears" break off easily - one was already broken in the box, and the sides are exposed as the panels are just sandwiched together with standoffs - not an enclosed box.

It is exactly what I needed to switch between 2 stereo DI's on my pedal board, really great passive switch with no noise and no pop between switching. However, the release doesn't seem to work with all XLR latches.I have 4 xlr cables stuck in the unit's input connectors. One cable connected to a snake I absolutely had to have back I was able to get out by disassembling the unit (luckily the case is no harder to disassemble and reassemble than a raspberry pi case), pop off the soldered on connector and manually dislodge/eject the cable with a screwdriver...but once I reassembled the unit, everything else seemed to still function properly. Clean sound, no pops when switching the dial...hah, guess I'll use that spare stereo channel (now mono) as a mute.At first I thought it might be that particular cable, but it happened with two different brands, and brand new cables I got specifically for use with this unit.I did consider sending it back, but honestly, it still works for my purpose, and this seems like it would be a hassle of a return/refund process. Still a great piece of gear at a great price, and maybe it was just mine, but be weary of which cables you use and be sure they can dislodge properly.

I use this for switching between a DAC for Headphone use with Gaming/Movies/TV and Music Listening on IMac and also an Audio Interface connected to the iMac for Guitar Tracking and Recording Music. The XLR cables coming from the OUT from the Switcher go into a pair of Balanced KRK Monitor speakers. So I can use the Monitor speakers for Music Creation with the Audio Interface connected to iMac or Switch over to the DAC for Gaming, watching TV or listening to Music through the Monitor speakers. Cool thing about this XLR Switch Box is it doesn't even need to be plugged in with a power source. It's a total Home Run

UpdateIt was great while it lasted, after two years, channel B is no longer picking up sound. The other channels work so I know there’s something up with it. Too bad, it was good well it lastedAre use this to run different inputs into my single channel preamp in my studio. It is hooked up to a to microphone, an XLR direct output from my guitar amp, and a dynamic mic. Simple hook up, doesn’t seem to degrade the sound, very cool

For the first week device worked well and audio quality was great. Since then the left output jack has become loose causing the audio to frequently change volume or cut out entirely. I have tested with multiple different cables but I have confirmed it is a problem with the jack which is unable to support the weight of a standard xlr cable without shifting and disconnecting. Pretty disappointed with how quickly this product failed.
