## Description

Nobsound Little Bear MC3 3-IN-3-OUT XLR Balanced/RCA Stereo Converter Audio Selector Splitter Box Passive Preamp XLR to RCA Audio Switch

Review: Great switching unit - Great at what it does Its not a amplifier its a switch control unit! I am using it as ballanced input/output sellector from my dac which has its own volume control instad of my pre amp. Also using RCA inputs from my AV reciever to switch to ballanced out to my power amplifier. My dac is a dual mono 6x5 / 6n23p tube dac based on a ES9038PRO chip with lampizator circuit. Power amp is a diy nelson pass aleph 5 power amp. Sound quality has improved in detail & bass depth by removing my aleph p1.7 and using this control unit.
Review: Does exactly what it says… - So, this little box is exactly what I needed as I have a DJ and live band both with all their own gear, mixer etc to switch between the same PA system. It works a dream and there is no noise as the switches are moved positions. Not even a small click. Great build quality - feels really robust and the switch action is really positive and nice. Not 5 stars as, for something of this price I would hope the marks on the switches would actually line up with the icons on the case. They are annoyingly just not right. Also, it is pricey for the simple functionality.

## Questions & Answers

**Q: Does this work as pre amp for turntable?**
A: It’s a passive pre amp, so it does not boost the signal like a powered amp. It does however convert unbalanced RCA outputs to balanced XLR outputs. Not what you were looking for actually.

**Q: Can this work on active speaker**
A: I connect mine between 2 DAWs and my active Adam 3X monitors and they work fine. As far as I am aware the  unit is only a switch box and has no active buffers involved so the signal should be carried through without any electronic conditioning

**Q: Is this a 1:1 converter regarding voltage? for example i need to preserve the 4v out of a dac balanced xlr output to an amp's single ended rca input**
A: I have checked signal level visually in Audacity and level is unchanged when passes through rca in to rca out, compared with direct path. I don’t know if this the same as voltage. It is also not a converter, it simply passes input to output. If the xlr  input is balanced, then xlr output is balanced. If input is not balanced, then using xlr output, signal is still unbalanced. I hope that helps

**Q: Hi, Is it possible to run  2XLR outputs (phono stage/ streamer) into one XLR amp input with this unit?**
A: Yes, there are two balanced inputs and one unbalanced to choose between. It is a switched selector, not a mixer. If you only need one output to an amp then you'll be leaving the RH knob alone.

### ⭐⭐⭐⭐⭐ Good Product
*by S***D on 8 January 2023*

I wanted a switch so that I could use a Desktop PC and a DJ Controller for one set of XLR speakers. My setup was initially from the PC (3.5 Audio cable) = (RCA Y-Splitter cable) = (RCA cables) = SWITCH = (XLR Cable) to speakers, however using this method the speakers would make a crackling noise when turning up the volume. I did not get the same crackling noise when switching XLR DJ Controller to XLR Speakers. To solve this I bought a one cable running from PC to the Switch (3.5mm Jack to Dual XLR Male Y-Splitter Cable) = (SWITCH) = (XLR CABLE) to Speakers. So I guess its better to have better insulated cables and less cable connections.
