"This mixer is in very good working condition. The unit powers on and remains stable throughout use. All channels are passing signal and all parameters are functional, except for channel 3, which does not pass signal and exhibits an audible hum. The EQ works well, as do the "Bright" and "Deep" tone options. The VU meter is not active or working per our test. However, overall this mixer is in very good working condition."

LOL.
