With these settings you can adjust the audio quality when recording tracks to the HDD. Recordings made with higher bitrates use 
more space, reducing the total available space on the HDD.

Recording mode settings at the time of purchase:
The recording mode for each selector is set to “LPCM” at the time of purchase. The recording mode for each selector can be set 
individually

(

➜ page 34).

If you want to change the recording mode to AAC, please note the following:
Recordings made to this unit are initially recorded in LPCM, and then are converted to AAC. Therefore if you are making 
continuous, long recordings, the maximum amount of recordings you can make must fit within the LPCM limits for maximum 
possible recording time as described in the chart above. In the event that you are making many recordings, continue recording 
after the music data has been converted to AAC format (

➜ page 32, How recordings work).

[Note]
LPCM audio quality does not exceed the audio quality of the original recording.

LPCM

Approx. 104 hours

The audio signal is digitally recorded without any 
compression.

AAC(XP) 
128 kbps 

Approx. 1,230 hours

The audio is initially recorded as LPCM and converted to 
AAC when this unit is in standby mode.
AAC is a compression format which compresses the audio 
data into a smaller size. Audio quality and the amount of 
tracks that can be recorded will differ depending on the 
bitrate.

AAC(SP) 
96 kbps 

Approx. 1,640 hours 

AAC(LP) 
64 kbps 

Approx. 2,460 hours
