11. Signal Flow Diagram
The signal flow diagram depicts how audio signals pass through the various processors in the
hardware. It shows audio signal flow as moving from left to right along the input and output
channel strips. Each channel strip contains fixed components for adjusting gain and mixing
channels. They also contain a series of empty slots for adding different types of processing.
12. Input Channel Strip
The input channel strips correspond to the four input channels of the System Processor. Each strip
accommodates up to five different signal processors.
13. Input Channel Label
This displays the channel label that you specify in the Input Gain window.
14. Input Gain
This is the initial stage of the System Processor’s gain structure. Double-clicking this block opens
the Input Gain window, which provides you with –10dBV/+4dBu scaling options, channel mute,
polarity control, and a +/–30dB fader for each input channel. This is also where you name your
input channels.
15. Mode Indicator
This displays the current mode of the signal flow diagram, as illustrated below.

16. Input Selector
Click on these numbered input selectors at the mix point of each output strip to connect
automatically with the corresponding input channel mix point.
17. Matrix Mixer
This is the intermediate stage of the System Processor’s gain structure. Double-clicking this block
opens the Matrix Mixer window, where you can route signal from any input channel strip to any output
channel strip, and adjust relative levels with fader controls. This window has a separate tab for each
output channel strip that displays gain, polarity, and mute controls for every input channel connected to
its mix point.
18. Channel Numbers
These numbers correspond to each of the four input and eight output channels of the P4800.
19. Mix Points
Click on these points to route signal between input strips and output strips. Lines appear between
points that are connected, depicting the signal flow. Each input strip may be connected to any or
all output strips.
20. Processor Slots
These slots serve as containers for processor modules. They can be populated either by using the
drag and drop method from the Processor Toolbox, the [Add Processor] option on the main menu,
or the contextual menu available with a click of the right mouse button.
