[. . . ] If the set up has been made for the driver's seat, the optimum delay time for the listener's position can be set up by simply switching the position selector function (refer to page 15) to the listening position. (This system automatically calculates and sets up the optimum delay time for each position. ) 32 Example: making corrections for the driver's seat in a left-hand drive vehicle · Measure the distance between the head of the listener, when sitting in the driver's seat, and each speaker unit. Note: · The unit of distance must be centimeters. Left Speaker (L) Right Speaker (R) Front tweeter (high-range) r1 Front mid (mid-range) r3 r5 Front tweeter (high-range) r2 r4 r6 Front mid (mid-range) Audio Adjustment <Network> Front bass (low-range) Front bass (low-range) r7 r8 Subwoofer (ultrabass-range) Subwoofer (ultrabass-range) Note: · It is recommended that the boxes be filled in as the measurements are made, as this information may prove useful at a later date. · Measure the distances to be corrected in the same manner for other systems than those used in the above example. 33 Audio Adjustment <Network> Inputting the distance to be corrected (Delay Time) Scope of adjustment: 0 cm to 192. 5 cm (0. 77 cm/1 step) (S. W. : 0 cm to 385 cm (1. 54 cm/1 step)) 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. 3. Press the FUNCTION button 6 and select the driver's seat (position). Press the buttons to switch between "FRONT-R" and "FRONT-L". Select the position when measuring the distance to be corrected as shown on the page 33. Note: · The correct distance can not be input unless these operations are conducted. 4. Press FUNCTION buttons 3 or 5 and select the speaker channel to input. Press the buttons to switch between left (L) and right (R). 5. Press FUNCTION buttons 1 or 2 and select the band to input. Each press of the FUNCTION buttons 1 or 2 select the desired band in the following order: S. W. (ultrabass-range) Ô LOW (low-range) Ô MID (mid-range) Ô HIGH (highrange) 34 6. Press the 5/ buttons to input the distance to be corrected (delay time). Input the distance to be corrected, as measured on page 33. Holding down these buttons continues their operations (during distance tuning, holding down the button moves the distance 1. 54 cm/1 step). 7. Carry out time alignment adjustments for the other speaker units. Repeat steps 4 to 6 to input the distance to be corrected for each speaker unit. Note: · Some systems may indicate values for speaker units which are not connected. Verify the composition of the system in order to correctly adjust the bands for the connected speaker units. 35 Audio Adjustment <Network> 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. Range Subwoofer-range Low-range Mid-range High-range Cut-off frequency of H. P. F. 20 Hz to 100 Hz 25 Hz to 250 Hz 160 Hz to 10 kHz 1. 6 kHz to 20 kHz Cut-off frequency of L. P.

P. F. Note: · When the slope is set as PASS, the audio signals bypass the filter circuit, cutting out the effect of the filter circuit. · In order to protect the speaker unit, H. P. F. has no PASS set up for high ranges.
