See all 20 pix. I’m no expert but. Tested this unit out. Mic is NOT included. All seems to work fine. Controls all worked as they should. One issue is that the VU modulator needle does not move. The panels do light up. All digits work on screen. I got the results on the 3 meter display as shown. Rated at 10 and 25 watts. Don’t know if its be modded.
