Setting the Media Xpander mode MX (Media Xpander) makes vocals or instruments sound distinct regardless of the music source. The CD and iPod, etc. will be able to reproduce the music clearly even in cars with a lot of road noise.  Setting item: MX SETTING 1 Turn the Rotary encoder to select the source to which you want to apply Media Xpander, and then press ENTER.

BASS ENGINE SQ Function With the BASS ENGINE SQ function on this unit, several parameters affecting Bass performance are adjusted simultaneously. The Bass Level adjustment varies these parameters uniformly for optimum Bass effect at different levels. Switching BASS ENGINE SQ mode Press and hold BASS for at least 2 seconds to switch the sound mode. BASS ENGINE SQ  MANUAL SET (Initial setting) BASS ENGINE SQ: Adjust the relevant Bass parameters uniformly and automatically. MANUAL SET: Adjust each audio effect setting separately and manually. Notes • This operation can also be performed by selecting BASS ENGIN in Audio Setup mode. Refer to "Setting BASS ENGINE SQ ON/OFF" on page 17. • You can access the Sound menu mode directly by pressing BASS when BASS ENGIN is set to OFF. • You can set this item via the TuneIt App on a Smartphone. Refer to "Adjusting the sound via the Smartphone" on page 26. • If you switch the 2WAY/3WAY system (page 23) to 3WAY mode, you cannot adjust this item. Adjusting BASS ENGINE SQ Level With BASS ENGINE SQ ON, adjusting the Bass Level uniformly effects various sound parameters for optimum Bass effect. 1 Press BASS to display the BASS ENGINE SQ Level adjustment screen. The unit's back lighting changes to white amber during this period. 2 Turn the Rotary encoder to select the desired level (+0 - +6). The initial level is +3. Notes • Adjustable only when DEFEAT is OFF. • Adjustable when 2WAY/3WAY system mode is set to 2WAY. • The Bass parameters affected contain EQ PRESETS, 9BAND EQ, SUBWOOFER (when set this item via TuneIt App), X-OVER, SUBW SYS and MX SETTING. These items are set automatically in BASS ENGINE SQ mode and cannot be adjusted separately. • From Level 0 to Level 6, the effect of BASS ENGINE SQ Enhance increases level by level. • If no operation is performed for 5 seconds, the unit automatically returns to normal mode. About Setup when the external power amplifier is connected. In order to optimize the BASS ENGINE SQ, we recommend the following power amplifier setup. After setting up, you can adjust the BASS ENGINE SQ Level according to the music. 1 Set gain of the power amplifier to "MIN". 2 Set the Crossover Mode Sector switch to "OFF". 3 Set the BASS ENGINE SQ of this unit to "ON", and the BASS ENGINE SQ Level to "+3". 4 Play a song of the genre you frequently listen to, and adjust gain of the power amplifier. About Time Correction The distance between the listener and the speakers in a car vary widely due to the complex speaker placement. This difference in the distances from the speakers to the listener creates a shift in the sounds image and frequency characteristics. This is caused by the time delay between the sound reaching the listener's right versus the left ear. To correct this, this unit is able to delay the audio signal to the speakers closest to the listener. This effectively creates a perception of increased distance for those speakers. The listener can be placed at an equal distance between the left and right speakers for optimum staging. The adjustment will be made for each speaker in 3.4cm steps. Example 1. Listening Position: Front Left Seat Adjust the time correction level of the front left speaker to a high value and the rear right to zero or a low value. 0.5m 2.25m 5.1ms The sound is not balanced because the distance between the listening position and the various speakers is different. The difference in distance between the front left speaker and the rear right speaker is 1.75 m (68-7/8"). Here we calculate the time correction value for the front left speaker in the diagram on the above. 20-EN
