Section 04 Available accessories LOW (low)-MID (mid)-HIGH (high) 7 Touch b and then touch c or d to select the center frequency of selected band. Touch c or d until the desired frequency appears in the display. 40Hz-50Hz-63Hz-80Hz-100Hz-125Hz -160Hz-200Hz-250Hz-315Hz-400Hz- 500Hz-630Hz-800Hz-1kHz-1.25kHz- 1.6kHz-2kHz-2.5kHz-3.15kHz-4kHz- 5kHz-6.3kHz-8kHz-10kHz-12.5kHz 8 Touch b and then touch c or d to adjust the equalizer level. Each time you touch c or d it increases or decreases the equalizer level. +12 to -12 is displayed as the level is increased or decreased. 9 Touch b and then touch c or d to select the desired Q factor. Each time you touch c or d switches between the following Q factor: NARROW (narrow)-WIDE (wide) # You can adjust parameters for each band of the other speakers in the same way. Note You can select a center frequency for each band. You can change the center frequency in 1/3-octave steps, but you cannot select frequencies that have intervals shorter than 1 octave among the center frequencies of the three bands. Using the auto-equalizer The auto-equalizer is the equalizer curve created by auto TA and EQ (refer to Auto TA and EQ (auto-time alignment and auto-equalizing) on this page). You can turn the auto-equalizer on or off. 1 Touch NEXT twice on the DSP function menu. 2 Touch AUTO EQ. # You cannot use this function if auto TA and EQ has not been carried out. 3 Touch d to turn the auto-equalizer on. # To turn auto-equalizer off, touch c. Auto TA and EQ (auto-time alignment and auto-equalizing) The auto-time alignment is automatically adjusted for the distance between each speaker and the listening position. The auto-equalizer automatically measures the car interior acoustic characteristics, and then creates the auto-equalizer curve based on that information. WARNING To prevent accidents, never carry out auto TA and EQ while driving. When this function measures the car interior acoustic characteristics to create an auto-equalizer curve, a loud measurement tone (noise) may be outputted from the speakers. CAUTION ! Carrying out auto TA and EQ under the follow- ing conditions may damage the speakers. Be sure to check the conditions thoroughly before carrying out auto TA and EQ. - When speakers are incorrectly connected. (e.g., When a rear speaker is connected to a subwoofer output.) - When a speaker is connected to a power amp delivering output higher than the speaker's maximum input power capability. ! If the microphone is placed in an unsuitable position the measurement tone may become loud and measurement may take a long time, resulting in a drain on battery power. Be sure to place the microphone in the specified location. 78 En
