  • Page 14: Adjusting The Listening Position

    Audio Adjustment <Main> Adjusting the Listening Position <PS> (Open state) One way to assure a more natural sound is to clearly position the stereo sound image (putting you in the center of the sound field). The Position Selector function adjusts distance and volume level of sound from each speaker to match seat positions and the number of people in the car, and lets you recall set- tings at the touch of a button.

  • Page 15: Fine Tuning The Position

    Fine Tuning the Position After choosing the position using the Position Selector function, it is possible to fine tune the distance and the difference in sound levels. Conduct the fine tuning to match the loca- tion of the left and right speakers and the shape of the car and correct the position of the sound image so that the sounds are most natural.

  • Page 19: Audio Adjustment

    Audio Adjustment <Equalizer> About the Equalizer Menu One important factor for creating quality sound is the correction of disturbances in fre- quency characteristics within the complex shape of a vehicle interior. Reflected sounds have a strong effect on direct sound in a vehicle because of the vehicle’s shape, the confined space, absorption of sound by the seats and reflection from the win- dows.

    The points when adjusting the equalizer curve • Take the recreated frequency bands of the speakers into consideration when adjusting. For example, when a speaker with a band between 80 Hz and 4 kHz is connected, adjusting the level in 50 Hz or 10 kHz will have no effect.

    Audio Adjustment <Equalizer> Adjusting the 31 Band Graphic Equalizer <FINE> (Open state) Adjustable frequency : 20 Hz — 20 kHz (Every 1/3 octaves, total 31 bands) Level adjustment range: –12 dB — +12 dB (0.5 dB/1 step) 1. Open the cover of the remote control in the Equalizer Menu (refer to page 4).

  • Page 23: The Flat Function

    The Flat function <FLT> (Open state) The adjusted equalizer curve can be temporarily returned to its prior status before making the adjustment (all levels are 0 dB), using the Flat function. This is convenient for checking the effects of the adjusted equalizer curve. 1.

  • Page 24: Audio Adjustment

    Audio Adjustment <Network> What is the Multi-Amp System? The multi-speaker system reproduces each frequency band (high, mid, low and ultrabass- ranges) through its own exclusive speaker unit. The multi-amp system provides an exclusive power amplifier for each speaker unit. There is only limited space in a vehicle for installing speakers, and it is difficult to install large-diameter speakers in a door or on the dashboard and get high sound quality.

    Network Menu <N.W.> With this menu, you can make the following adjustments. • Time Alignment Adjustment <T.A.> (Open state) • Filter Adjustment <FTR> (Open state) • Memory functions of Adjusted Network (Open state) (Refer to page 34.) Switching to the Network Menu •...

  • Page 26: Switching To The Network Menu

    Audio Adjustment <Network> Time Alignment Adjustment <T.A.> (Open state) In the vehicle, the different speaker units are at widely differing distances from the listener. The sounds from the speakers therefore reach the listener at different times. When a multi-amp system is set up, this causes different delays for each frequency band (high, mid, low and ultrabass-ranges), marring the position of the sound image and the overall balance and disturbing the frequency characteristics.

  • Page 30: Filter Adjustment

    Audio Adjustment <Network> Filter Adjustment <FTR> (Open state) The following adjustments can be made during filter adjustments. Make the appropriate adjustments for the reproduced frequency band and characteristics of the connected speaker unit. Filter frequency adjustment: Every 1/3 octave Level adjustment: 0.5 dB/1 step The cut-off frequencies of the high pass filter (H.P.F.) and the low pass filter (L.P.F.) of each band (subwoofer, low, mid, high) and the reproduction level of each band are set up.

  • Page 31: Switching To The Filter Adjustment Mode

    About the H.P.F. and L.P.F. High pass filter eliminates lower sound ranges (low-range) from the set up frequencies and allows high ranges through. Low pass filter eliminates upper sound ranges (high-range) from the set up frequencies and allows low ranges through. About the slope This value indicates how many dB the signals attenuate when the frequency increases (or decreases) 1 octave (unit: dB/oct.).

  • Page 32: Adjusting The Filter

    Audio Adjustment <Network> Adjusting the Filter First, determine the approximate band to be used, taking into consideration the reproduced frequency band and the characteristics of the connected speaker. 1. Open the cover of the remote control in the Network Menu (refer to page 4). This switches to Network Menu Setting Screen.

  • Page 33

    7. Press the 5/∞ buttons and adjust the level of each band. Holding down these buttons continues their operations. Switch to each band and adjust the level in order to create a better overall balance. 8. Press FUNCTION button 3 and adjust the slope of each filter.

  • Page 34

    Audio Adjustment <Network> Important points in adjusting the slope • A decrease in the absolute value of the slope (more gentle inclination) makes the frequency characteristics more susceptible to interference from the next band. • Increasing the absolute value of the slope (sharper inclination) lessens the connections between bands, giving the listener the impression of hearing separate, unrelated sounds.
