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:

Subwoofer*1 Bass Level Treble Level Balance Fader Loudness Defeat Volume Subwoofer

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.

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

2 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 23).
