AUDIO/VIDEO SYSTEM (c) Tone and balance How good an audio program sounds to you is largely determined by the mix of the treble, midrange, and bass levels. In fact, different kinds of music and vocal programs usually sound better with different mixes of treble, mid−range, and bass. A good balance of the left and right stereo channels and of the front and rear sound levels is also important. Keep in mind that if you are listening to a stereo recording or broadcast, changing the right/left balance will increase the volume of one group of sounds while decreasing the volume of another. 1. Push the "TUNE/FILE"/"AUDIO" knob. 3. Adjust the tone and balance as follows: To adjust the tone, touch "+" or "−" on the screen. To adjust the balance between the front and rear speakers, touch "FRONT" or "REAR" on the screen, and to adjust the balance between the left and right, touch "L" or "R" on the screen. "TREB": Adjusts high−pitched tones. "MID": Adjusts mid−pitched tones. "BASS": Adjusts low−pitched tones. As the yellow display approaches "+", each tone is more emphasized. (d) Automatic sound levelizer (ASL): When the audio sound becomes difficult to be heard due to road noise, wind noise or other noises while driving, the system adjusts to the optimum volume according to the noise level. To turn this function, touch "ASL" on the audio control screen. 2. Touch "SOUND". 190
