1. System Overview
The A5000/A4000 is capable of recording, processing, and playing back musical instrument sounds, sound
effects, segments of complete tunes, or just about any type of sound. The basic A5000/A4000 system con-
figuration is described below.
Internal Structure
The A5000/A4000 consists of a tone generator, effect stage, total EQ stage, controllers, sequencer, and I/O
interface.
Sampling Tone Generator (page 59)
This section records audio signals received via the analog input jacks (or the digital coaxial or optical
inputs, if the optional I/O board is installed), and allows the recorded samples to be played from an
external MIDI controller. This is the “heart” of the A5000/A4000 system.
Effect Stage (page 63)
The effect section adds ambience effects such as reverb or more dramatic effects to the output signal
from the tone generator section. Effects can also be added to input signals as they are recorded.
A comprehensive range of 96 effects is provided in 6 individual effect blocks (3 in the A4000).
