SERVICE ON THIS EQUIPMENT IS TO BE PERFORMED BY EXPERIENCED REPAIR TECHNICIANS ONLY 4 Overview The powered mixer series consists of 5 models: the 406M, 408M, 408S, 808M and 808S. Each consists of five circuit boards: Effects, Amplif

15、ier, Mixer, Output and AC power. This table shows which boards are used in each mixer. Note: Each schematic chapter is labeled with the number of the board it describes. For example, chapter 252 contains schematics and pcb layouts for circuit board number 550-252-00, chapter 193 is for circuit board

All models use the same effects board and

17、output board. There are two different amplifier boards (800 watts and 400 watts), three different mixer boards (8 channel Mono, 8 channel Stereo and six channel Mono) and two types of AC power board (one for the 800 watt models, one for 400 watts). All models use the same cabinet, feet, handles, pow
