The bass and vocal sound that are cutoff by encoding are supplemented for the reproductionof natural sound quality. Supplementing is optimized bycompression format (AAC, MP3 or WMA) and processedaccording to bit rate. The effect is negligible with musicthat is encoded at high bit rate, variable bit rate or hasminimal high frequency range.The bass and vocal sound of Music CD/ iPod is alsosupplemented.• Dual Zone SystemMain source and sub source (Auxiliary input) output Frontchannel and Rear channel separately.Audio ControlYou can adjust following Audio Setting items.Display Overview“SubWoofer Level” You can set subwoofer level.“–15” — “0” — “+15”“DSP Set” “Bypass”: Disables the DSP function.“Through”: Enables the DSP function.“Equalizer” Sets the sound quality.- Preset Equalizer curve Select (page 41).- Manual Equalizer Control (page 41).“Bass Boost” Sets the Bass Boost level in two steps.“OFF”/ “Step1”/ “2”“HIGHWAY-SOUND” Compensates the low volume or bass soundbeing lost by road noises to make vocal soundclearer.“OFF”/ “Step1”/ “2”/ “3”“Supreme+” Turns ON/OFF the Supreme plus function.Can be set while Music CD source, Audio filesource of USB and iPod source.“ON”/ “OFF”“Position” Compensates the sound environment inaccordance with the listening position.- Listening Position Selection (page 42).- Listening Position Fine Adjustments (page42).“Balance” Adjusts left/right speaker balance.(Left) “L15” — “0” — “R15” (Right)“Fader” Adjusts front/rear speaker balance.(Rear) “R15” — “0” — “F15” (Front)“2Zone Rear Volume” Refer to (page 42).“SubWoofer” Turns on/off the subwoofer output.“ON”/ “OFF”“Detailed Setup”“Car Type” To get clear sound, set the sound environmentaccording to the location and size of physicallyinstalled speakers with reference to thefollowings:- Car Type Selection (page 44).- Speaker Setting (page 44).- Car Type Fine Adjustments (page 45).- X’Over Setting (page 46).“Speaker”“Car Type Adjust”“X'Over”“Volume offset” Sets each source’s volume as a difference fromthe basic volume.“–8” — “0” (AUX: “–8”— “+8”)SRC4VOL¢MENU
