Overview
The powered mixer series consists of 5 models: the 406M, 408M, 408S, 808M and 808S. Each
consists of five circuit boards: Effects, Amplifier, 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 550-193-00.

Two types of power transformer are used, one for the 406M, 408M and 408S and one for
the 808M and 808S.
All models use the same effects board and 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, power switch, IEC power jack.
