Sound Setting; Adjusting Subwoofer/Bass/Treble/Balance (Between Left And Right)/Fader (Between Front And Rear)/Loudness/Defeat - Alpine iDA-X305 Owner's Manual

Terminology
Bit rate
This is the "sound" compression rate specified for encoding. The
higher the bit rate, the higher the sound quality, but also the larger
the files.
Sampling rate
This value shows how many times per second the data is sampled
(recorded). For example, music CDs use a sampling rate of 44.1 kHz,
so the sound is sampled (recorded) 44,100 times per second. The
higher the sampling rate, the higher the sound quality, but also the
larger the volume of data.
Encoding
Converting music CDs, WAVE (AIFF) files, and other sound files into
the specified audio compression format.
Tag
Song information such as track titles, artist names, album names,
etc., written into MP3/WMA/AAC files.
Root folder
The root folder is found at the top of the file system. The root folder
contains all folders and files.

Sound Setting

Double Action encoder
(IMPRINT)
If either an external or IMPRINT audio processor is connected, the
Sound Setup screen is not displayed. For an external audio processor,
refer to "Audio Setting" (page 22) of "SETUP" (page 19) to adjust the
sound. For an IMPRINT audio processor, refer to "IMPRINT Operation
(Optional)" (page 23) to adjust the sound.
Adjusting Subwoofer/Bass/Treble/Balance
(Between Left and Right)/Fader (Between
Front and Rear)/Loudness/Defeat
1
Press (IMPRINT) repeatedly to choose the
desired mode.
Each press changes the mode as follows:
1
Subwoofer* Bass Level
Fader Loudness Defeat
Subwoofer: 00 ~ 15
Bass level: –7 ~ +7
Treble level: –7 ~ +7
Balance: Left15 ~ Right15
Fader: Rear15 ~ Front15
Loudness : ON/OFF
Defeat : ON/OFF
Volume: – ~ 0 dB
• Loudness introduces a special low and high frequency
emphasis at low listening levels. This compensates for the
ear's decreased sensitivity to bass and treble sound. The
function is inoperable when Defeat is set to ON.
• By setting Defeat ON, previously adjusted setting of Bass,
Treble and High Pass Filter will return to the factory defaults.
• If (IMPRINT) is not pressed for 15 seconds after selecting the
Subwoofer, Bass, Treble, Balance or Fader mode, the unit
automatically returns to normal mode.

* When the subwoofer mode is set to OFF, its level cannot be adjusted.

Rotate the Double Action encoder until the
desired sound is obtained in each mode.
• Depending on the connected devices, some functions do not work.
• You can store the contents of Balance/Fader/Loudness settings after
completing. For how to store, refer to "Storing the Audio Adjustment
Level (User Preset)" (page 22).
