[. . . ] Consult your dealer from which the products were purchased if adjustments are difficult. · When adjustments have already been made at your dealer, the optimum setup for vehicle's particular interior has already been installed in the memory. In this case, recall the corresponding memory for use (refer to page 45). When completing the adjustment · It is recommended that adjustment settings be stored in memory soon after the adjustments are completed. · After completing the network adjustments, adjust the overall balance of the sound image by using the position fine tuning function of the main menu as necessary (refer to page 16). 31 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. The time alignment adjustment function is able to synchronize the arrival times of the different sounds by delaying the output of signals from the closest speaker units. Switching to the time alignment adjustment mode 1. Open the cover of the remote control in the network menu (refer to page 5). This switches to network menu setting screen. 2. Press the FUNCTION button 2. The display switches to time alignment adjustment screen, allowing time alignment adjustment. Measuring the distance to be corrected (Delay Time) It is necessary to calculate the delay time to correct the time differences between speaker units. In order to adjust the time alignment adjustment function more easily, this system allows the delay time to be set up by simply inputting the difference in the distance between speaker units (the distance to be corrected). (The delay time will be automatically calculated by this system. ) Although the distance from each speaker unit varies depending on the position of the listener, the first set up is made for the driver's seat. 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. ). Increasing the degree of the slope increases the degree of signal attenuation. Note: · Setting the slope of H. P. F. of the low-range as PASS creates a full range setup. Switching to the filter adjustment mode 1. Open the cover of the remote control in the network menu (refer to page 5). Audio Adjustment <Network> This switches to network menu setting screen. 2. Press FUNCTION button 1 on network menu setting screen. The display switches to filter adjustment screen, allowing filter adjustments. Using the mute function (MUT) It is possible to turn the mute function ON/OFF for each band. Turning ON the mute function stops the sound output for that band. Adjust the filter while turning the mute function ON/OFF as necessary. 1. Select the band for which the mute function is to be turned ON. To select a band, consult "Adjusting the filter" on the following page. 2. Press FUNCTION button 5 switches the mute function ON/OFF. When muting is turned ON the filter curve displayed disappears from the display. [. . . ] LPF frequency: 250 Hz to 10 kHz, 1/3 oct. Gain: 0 dB to ­24 dB (0. 5 dB) MID . . . . . . . . .
