• You can also adjust the volume by turning the 

[VOLUME] control on the main unit.

• Press [FADE MUTING] again or [AUDIO VOL +] 

to restore the sound. The sound is also restored 
when the main unit is turned off once and turned 
on.

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).

• 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. 

For the locations of the remote 
control buttons, refer to page 14.
