Sony DPS-V77 service manual Block and structure, Setting the INPUT/OUTPUT levels, ~CH2

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 audit) signal processor in this unit is divided into two parts, BLOCK 1\ and BLOCK B. Each of tlwse blocks is composed of an EQ BLOCK and (\n FX (dfect) BLOCK. Thl' EQ BLOCK works as anl'qualizer. The FX BLOCK contains a large number of multi·dfe'cls.

The positioning of the EQ block and the rX.block is determined when editing the EQ BLOCK by c1wosing either "Pre" or "Post" in the IModel parameter. In other words.

It's abt) l1l'cessary to dett'rmine the positions of the larger blocks. BLOCK 1\ and BLOCK B. Thdr pt)sitioning, the way they arc connected, is called the "structure." Set the structure according to the kind of sound you want to make. The structlire screen not onl\' lets vou choose the structure type (see the following chartl. but also lets you adjust the output I"\'el for each block (represented in the chart by the MIX BLOCK).
