I bought a mixer (Alesis MultiMix 4) thinking I would be able to connect multiple stereo audio sources (jack or mini jack) , adjust their level which each knob and output everything on a pair of monitoring speakers. For instance, the output of the phono preamp + computer + bluetooth receiver.
The mixer fails to complete this task because the 2 of the 4 inputs are mono and not stereo (which I foolishly thought they were).
So, is there any (cheap if possible) piece of hardware which would allow me to have multiple stereo audio sources plugged in the monitoring speakers and control their volume independently?
Edit:
I know there are other mixers out there such as Soundlab Micro Mixer, but I was wondering if there was another piece of kit which would do the job.
