The K2 function is designed to provide natural
sound by improving the playback sound from low-
bit-rate digital sources.
The function compensates for sound waves dissi-
pated during digital recording compression to
approximate the original analog sound. Sound is
reproduced with more bits (24 bit) and a wider
range of frequency (128 kHz, 176.4 kHz or
192 kHz).
Press [K2] on the remote control or on
the main unit.
When the K2 function is activated, the [K2] lamp
(button) on the main unit lights up.
Each time you press [K2], the display changes
as follows.
- “K2 Mode 1”:
Plays back a digital source with non-com-
pressed sound signals (linear PCM).
- “K2 Mode 2”:
Plays back a digital source with compressed
sound signals (Dolby digital, DTS, MP3 or
WMA).
-“K2 OFF:
Cancels the K2 function.
NOTE
The initial setting is “K2 OFF”.
If [K2] is pressed when the clear voice function,
headphone surround mode function, or 3D
PHONIC is activated, these functions are turned
off and the K2 function is activated.
If [K2] is pressed when an AM/FM broadcast or
an analog audio device connected to the [LINE1
IN] or [LINE 2 IN] terminal is selected as the
source, “ANALOG SOURCE” is displayed in the
display window, and the K2 function is not acti-
vated. The K2 function is activated when a
loaded disc, a connected USB mass storage
class device, or a digital audio device connected
to the [LINE 3 DIGITAL IN] terminal is selected
as the source.
The original range of frequency is automatically
detected and extended to a specific range.
When the original range is 32 kHz, 44.1 kHz or
48 kHz, the range is extended to 128 kHz,
176.4 kHz or 192 kHz respectively.
This function is available when “PCM ONLY” is
selected for “DIGITAL AUDIO OUTPUT” (refer to
page 43). “NO OPERATION” appears in the dis-
play window and the K2 function cannot be used
when “DOLBY DIGITAL/PCM” or “STREAM/
PCM” is selected.
