Extended K2 Processing
Version 2.0 Function
This section describes the Extended K2 Processing Version 2.0 function and how
to use it.
Basic Outline
Bit Extension and Frequency/Band Expansion
The Extended K2 Processing Version 2.0 technology is a new process that performs bit extension and band expansion
for the digital signal from CD and DVD discs to provide a sound quality that is closer to original sound. The process can
be divided into three parts, Bit expansion, Frequency conversion, and Band expansion, with each enhancement
applying supposition of the analog signal before conversion to a digital signal, and then quantization as a new high bit,
high sampling digital signal. This allows it to convert the audio from normal CD format or various DVD formats to a
maximum output of 24 bits and the frequency band by a maximum of four times for a high quality, high bit, high
sampling format.
How to Use the Extended K2 Processing Version 2.0, Function
■ To use the Extended K2 Processing version 2.0, press [EX K2] on the remote control or [EXTENDED K2
PROCESSING] on the player itself.
• The EXTENDED K2 PROCESSING indicator on the player comes on and the Extended K2 Processing Version
2.0, function is enabled.
The Extended K2 Processing Version 2.0, function effects the front L/R channels for the following discs.
• Audio CD, Video CD
• DVD Audio, DVD Video
(The function does not work for disc with a sampling frequencies of 176.4kHz, or 192kHz.)
Notice
• You cannot out put the signal that has been processed by the Extended K2 Processing to the digital output
(AUDIO DIGITAL OUTPUT) terminals.
