the t.mix MicroMix 2 USB

I got this unit for a friend who needed a microphone preamp - works OK-ish purely for this purpose , however finding little strange the gain knob has to be almost on maximum with all microphones I have tested, knowing they work ok on other mixers in more normal range of gain.

I was testing the bluetooth streaming function and noticed quite a lot of beeping and squeeking when the bluetooth button is enabled. It gets lost in during mid/loud volume playback, but quite annoying during more silent music or in between songs. I experienced some sound interruptions when moving the phone - for example just when tilting it in my hands. I found it working when I placed the phone up to around 5m away from the mixer, not moving it and having absolutely no obstacle between the phone and the mixer.

There is no guidance in the manual as to how to run the unit in a DAW software nor specific driver for download for this particluar device. I tried the ASIO4ALL, but I gave up after several attempts to make it working in Reaper or Cubasis without success. I am not saying it is not possible to run, but found it rather frustrating - the device sometime appeared in the DAW settings, but not sending the audio to the DAW. I normally use Yamaha MG mixers as audio interface and for me these work seamlessly without hesitation usingthe official Yamaha Asio drivers in several DAWs.

If I was about to use the mixer as an audio interface or bluetooth audio streaming, I would return it and tried something else.

For the price it is a good product, it has many features, including bluetooth reception. In an approx 40 euro product the features and usability are amazing. However I have to mention the issues it has, some are minor and some are more serious.

Of course in this price do not expect a good DAC, the signal from USB has a faint background noise, and with some songs and frequencies this background noise is more prominent. This is a minor thing since the input signals from the lines are much cleaner, and considering the price this is not a real issue.

However there is a serious issue which needs to be pointed out. When you switch it off, press the bluetooth button and especially when turning it ON, there is a very loud popping sound. This can destroy your speakers if you do not turn them off first or turn their volume completely down, Leaving the mixer volumes down will not help, the spike pop will still occur. To avoid it get in to the habit to turn off the speaker before switching on or off the mixer.

I bought this mix because I wanted to mix signals from PC (via USB), my guitar pedalboard (with preamp and cabinet simulation) and send it to headphones or Hi-fi system. Also the option of Bluetooth connection impressed me.
Secondary use of this mini mix is with my PA as basic mixer for garden parties, etc. It can take microphone and I have possibility to play music from various sources (notebook, phone via Bluetooth, mp3 player, etc.).

PROS: it is f*cking awesome product for that price

CONS: it has RCA connectors for line signals and Main outs, so I must use reductions RCA/6,3mm TS.

I highly recommend this mix, because I never had problems with it and it is working realy well.
