Understanding The Signal Flow - Sony DPS-V77 Mode D'emploi

Getting Started

Understanding the Signal Flow

This unit takes in audio signals from two types of input jacks (digital and analog), processes them using various
internal blocks, and outputs them through the analog and digital output jacks. To make the most of this unit, it is
essential that you have a firm understanding of the audio signal flow. This section provides an explanation of the
internal blocks and how they process the input and output audio signals.
Block and structure
The audio signal processor in this unit is divided into two parts, BLOCK A and
BLOCK B. Each of these blocks is composed of an EQ BLOCK and an FX (effect)
BLOCK. The EQ BLOCK works as an equalizer. The FX BLOCK contains a large
number of multi-effects.
BLOCK A

BLOCK
shifter, chorus,
The positioning of the EQ block and the FX block is determined when editing the EQ
BLOCK by choosing either "Pre" or "Post" in the [Mode] parameter. In other words,
you can choose, independently within BLOCK A and BLOCK B, wether to add the
effect to the sound coming from the equalizer, or equalize the sound produced by the
effect.

BLOCK
It's also necessary to determine the positions of the larger blocks, BLOCK A and
BLOCK B. Their positioning, the way they are connected, is called the "structure." Set
the structure according to the kind of sound you want to make. The structure screen
not only lets you choose the structure type (see the following chart), but also lets you
adjust the output level for each block (represented in the chart by the MIX BLOCK).
