Setting the Treble Control

You can change the Treble Frequency emphasis to create your own tonal preference.

CDE-9845/CDE-9843: TREBLE ↔ normal mode

CDE-9841:

BASS → TREBLE → normal mode → BASS

2-1Setting the treble Center frequency: Press g or f to select the desired treble center frequency.

7.5kHz ↔ 10.0kHz ↔ 12.5kHz ↔ 15.0kHz

The displayed Treble frequency is emphasized.

2-2Setting the treble level:

Turn the Rotary encoder (CDE-9845/CDE-9843 only) or press 4 and 3 (CDE-9841 only) to select the desired treble level (–7~+7).

You can emphasize the treble frequency.

•If no operation is performed within 15 seconds, the treble control setting will be turned off automatically.

•The treble level settings will be individually memorized for each source (FM, AM, CD, etc.) until the setting is changed. The Treble frequency settings adjusted for one source are effective for all other sources (FM, AM, CD, etc.).

•This function is inoperable when DEFEAT is set to ON.

Setting the BBE Mode (CDE-9845 only)

BBE makes vocals or instruments sound distinct regardless of the music source. The FM radio, CD, and MP3, will be able to reproduce the music clearly even in cars with a lot of road noise.

1Press SOURCE/POWER to select the source to which you want to apply BBE.

4Turn the Rotary encoder to select your preferred level (BBE1 to 3) or OFF.

5Press the Rotary encoder for at least 2 seconds to return to normal mode.

•To cancel BBE mode for all music sources, press the Rotary encoder to turn BBE off.

•BBE mode is automatically canceled if no buttons are pressed within 15 seconds.

•Each music source, such as FM radio, CD, and MP3/WMA can have its own BBE setting.

•Setting to BBE OFF sets BBE mode of each music source to OFF.

•This function is inoperable when DEFEAT is set to ON.

•There is no BBE mode for AM radio.

Turning Loudness On/Off (CDE-9843/CDE-9841 only)

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.

Press and hold the Rotary encoder (CDE-9843 only) or press and hold MODE (CDE-9841 only) for at least

2 seconds to activate or deactivate the loudness mode.

The display shows “LD” when the loudness mode is activated.
