Overview
The CFX mixer series consists of 3 models: the CFX•12, CFX•16 and CFX•20. Each consists
of five circuit boards: Effects, Master, Slave, Power and AC Power.
The Master board is the main mixer circuit.
The Effects board is fitted on the back of the Master board. This is exactly the same as
used in the PPM Professional Powered Mixer series.
The Slave board connects to the left of the Master board and adds four channels. The
CFX•12 has one Slave board, the CFX•16 has two, and the CFX•20 has three. This is the
main difference between the three models.
The power board regulates the AC power to +/- 15VDC, +5VDC and +48VDC (phantom
power).
The AC power board holds the IEC connector, fuse holder, power switch and caps.
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 241 contains schematics and pcb layouts for circuit board number
550-241-00, chapter 192 is for circuit board 550-192-00.
