Revolabs 01-EXESYS4 4 Channel Solo Executive Wireless Mic Base Rack Mount
When I first power on this unit the lights above the channel buttons flash green on a off for a few seconds. After that the channel 2 light flashes green then red for a few more second and then they all stop flashing but the power light stays lit. I am not able to test this further and so I am offering it AS-IS. Everything that is included is shown in the pictures.
