2 General
The Cloud Matrix 4 is a versatile four-zone mixer. The unit has applications where four
microphones a paging microphone and two line level music signals are required to feed up to
four separate areas with full user control of the signal routing. The CPM-4 four-zone paging
microphone is available as an accessory to the Matrix 4 (See section 13 for more details).
The front panel mounted signal routing and level controls have been kept to a minimum,
resulting in a logical layout easily understood by unskilled staff.
