Each consists o

21、f 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 Maste

22、r board and adds four channels. The CFX12 has one Slave board, the CFX16 has two, and the CFX20 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 hol

23、der, 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-

The CODEC also receives analog co

44、ntrol signals from the two Parameter pots, converts this to digital and sends a combined digital signal to the DSP. The DSP and the two SRAM ICs, form a powerful DSP system. The DSP receives the digital data from the CODEC as well as the direct control signals from the rotary encoder and the EFX WID

45、E switch. The DSP programing selects and performs the appropriate DSP function on the data, and sends it back to the CODEC. The CODEC converts the incoming digital signals to two analog outputs which are sent to the main left and right mix, and summed to the monitor mix. For Phaser and Delay effects, the two analog outputs from the CODEC are mono. For other effects, there is a difference between the signals.
