OVERVIEW _____________________________________________
Welcome to the Shure P4800 System Processor software guide. This document will help you understand how
the P4800 functions as you learn to use the software interface. The hardware stands alone as both a front-end
and back-end system processor that can be externally controlled by a simple end-user interface. The software
is the tool that configures the device's internal signal routing and audio processing. It is designed for small and
medium sized sound systems that need the power and flexibility that a digital signal processor can provide, but
also require a unit that's easy for the installer to configure and simple for the end user to work with.
Document Structure
The P4800 software interface is so intuitive and user friendly that you may be tempted to skip reading this
document and immediately begin programming the unit. Before you do, however, you should at least skim this
overview, then thoroughly read the Start-Up Guide on page 12. Any questions you have about the software will
be answered in the following sections of the document.
§
Overview ...................................Introduces the main features of the System Processor, and
discusses the operating modes of the interface and the main window.
§ Start-Up Guide..........................Covers the basic steps you need to follow with the
software to set up the System Processor for an installation.
§ Creating a Configuration.........Covers the elements of a System Processor signal flow
configuration, such as the gain structure of the device, routing signal from inputs to outputs,
adding processors to the signal path, and working with them in the main window.
§
Saving a Configuration............Explains how to save a configuration to the computer, store
it as a preset in the P4800, and backup the contents of the device to computer.
§ Processor Features .................Covers the features that are common among many of the
signal processor modules, such as fader controls, taking snapshots of parameter settings, and
saving and recalling settings to and from the computer.
§ Fixed Processors.....................Explains the features of the input and output gain
processors and the Matrix Mixer.
§ Modular Processors ................Explains the features specific to each of the modular
signal processors.
§ Control Pins..............................Describes the internal architecture of the System
Processor's external device control feature and explains how to configure the P4800's
control pins with the software once the external hardware has been connected.
§ Security.....................................Covers the security features of the System Processor
that restrict user access to device settings.
System Processor Features
The P4800 is a 4-input, 8-output digital audio processor with a software interface that completely replaces front
panel controls. It provides 24-bit conversion, 48khz sampling and a minimum dynamic range of 100dB.
SoundPlex digital signal processing ensures high performance and system stability. The device stores from 16
up to 128 user-defined presets, depending on the complexity of the configurations.
Drag and Drop Software Interface
The computer interface to the System Processor mimics the functional block diagrams used in sound
system design. This makes the software incredibly easy to learn, because the interface seems
immediately familiar to sound professionals. System configurations can be built and edited entirely by
clicking, dragging, and dropping with the mouse. The digital signal processing is highly configurable,
with modular signal processors that can be arranged in any user-defined order.
