A2 Live Sound Card With 48V Power Supply Multifunctional Audio DJ Mixer Microphone Volume Adjustment For Live Streaming Singing
Aliexpress UK
Yamaha MT50 four track recorder. In original box with manuals. Overall good condition, two of the LED level light covers are missing. I powered this up with a spare 12v supply and LEDs come on and tape transport seems to work as it should, ffw, rwd, play etc. I don't have a means of adding a line in to test further though. No power supply but takes a regular 12 adapter with a 2.1mm jack easily available via Amazon.
