Audio adjustments Using the equalizer Recalling equalizer curves There are seven stored equalizer curves that you can easily recall at any time. Here is a list of the equalizer curves: S.Bass is a curve in which only low-pitched sound is boosted. Powerful is a curve in which low- and high-pitched sounds are boosted. Natural is a curve in which low- and high-pitched sounds are slightly boosted. Vocal is a curve in which the midrange, which is the human vocal range, is boosted. Flat is a flat curve in which nothing is boosted. Custom1 is an adjusted equalizer curve that you create. If you select this curve, the effect is applied to all AV sources. Custom2 is an adjusted equalizer curve that you create. If you select this curve, the effect is applied to all AV sources. p The default setting is "Powerful". 1 Display the "Audio" setting screen. Refer to Displaying the "Audio" setting screen on page 44 2 Touch [Graphic EQ]. 3 Touch the equalizer. Customizing the equalizer curves You can adjust the currently selected equalizer curve setting as desired. Adjustments can be made with a 13-band graphic equalizer. p If you make adjustments when a curve "S.Bass", "Powerful", "Natural", "Vocal", or "Flat" is selected, the equalizer curve settings will be changed to "Custom1" mandatorily. p If you make adjustments when the "Custom2" curve is selected for example, the "Custom2" curve will be updated. p "Custom1" and "Custom2" curves can be created common to all sources. 1 Display the "Audio" setting screen. Refer to Displaying the "Audio" setting screen on page 44 2 Touch [Graphic EQ]. 3 Select a curve that you want to use as the basis of customizing. 4 Touch the frequency for which you want to adjust the level. 46 p If you trail a finger across the bars of multiple equalizer bands, the equalizer curve settings will be set to the value of the touched point on each bar. Setting the auto-adjusted equalizer You can set the auto-adjusted equalizer to suit the vehicle's acoustics. To use this function, the vehicle's acoustics must be measured in advance. The default setting is "Off". Refer to Adjusting the equalizer curve automatically (Auto EQ) on page 46 p To manually adjust the equalizer curve, set "Auto EQ&TA" to "Off". 1 Display the "Audio" setting screen. Refer to Displaying the "Audio" setting screen on page 44 2 Touch "[Auto EQ&TA] to switch "On" or "Off". Adjusting the equalizer curve automatically (Auto EQ) By measuring the vehicle's acoustics, the equalizer curve can be adjusted automatically to suit the vehicle interior. WARNING A loud tone (noise) may be emitted from the speakers when measuring the vehicle's acoustics. Never perform Auto EQ measurement while driving. CAUTION Thoroughly check the conditions before performing Auto EQ, as the speakers may be damaged if this is performed under the following conditions: When the speakers are incorrectly connected. (For example, when a rear speaker is connected as a subwoofer output.) When a speaker is connected to a power amp delivering output higher than the speaker's maximum input power capability. If a microphone for acoustical measurement (sold separately) is not placed in an appropriate location, the measurement tone may become loud and measurement may take a long time, resulting in battery drainage. Be sure to place the microphone in the specified location. Before operating the Auto EQ function Perform Auto EQ in as quiet a place as possible, with the vehicle engine and air conditioning switched off. Also, cut power to car phones or cellular phones in the vehicle, or remove them in advance. Surrounding sounds may prevent correct measurement of the vehicle's acoustics. Be sure to use the microphone for acoustical measurement (sold separately). Using another microphone may prevent measurement, or result in incorrect measurement of the vehicle's acoustics. To perform Auto EQ, the front speakers must be connected. When this product is connected to a power amp with input level control, Auto EQ may be impossible if the power amp's input level is set below the standard level. When this product is connected to a power amp with an LPF (low pass filter), turn the LPF off before performing Auto EQ. Also, set the cut-off frequency for the built-in LPF of an active subwoofer to the highest frequency. The distance has been calculated by a computer to provide optimum delay to ensure accurate results. Do not change this value. - The reflected sound within the vehicle is strong and delays occur. - The LPF on active subwoofers or external amps delay the lower sounds. If an error occurs during measurement, check the following before measuring the vehicle's acoustics. - Front speakers (left/right) - Rear speakers (left/right) - Noise - Microphone for acoustical measurement (sold separately) - Low battery Performing Auto EQ p Auto EQ changes the audio settings as follows: - The fader/balance settings return to the center position. Refer to Using fader/balance adjustment on page 44 - "Mute Level" is set to "Off". Refer to Switching sound muting/attenuation on page 44 p Previous settings for Auto EQ will be overwritten. CAUTION Do not turn off the engine while the measurement is in progress.
