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 from the vehicle before performing Auto EQ. Sounds other than the measurement tone (surrounding sounds, engine sound, telephones ringing, etc.) may prevent correct measurement of the vehicle's acoustics. Be sure to perform Auto EQ using 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, a message appears and measurement is canceled. 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: - "Auto EQ&TA" is set to "On". For details, refer to Using the auto-adjusted equalizer on page 64. - The fader/balance settings return to the center position. For details, refer to Using balance adjustment on page 60. - The equalizer curve switches to "Flat". For details, refer to Using the equalizer on page 64. - The front and rear speakers will automatically be adjusted to a high pass filter setting. p Previous settings for Auto EQ will be overwritten. p Do not press the button to open or close the panel when you are using the microphone. CAUTION Do not turn off the engine while the measurement is in progress. 1 Stop the vehicle in a quiet place, close all the doors, windows and sun roof, and then turn the engine off. If the engine is left running, engine noise may prevent correct Auto EQ. p If driving restrictions are detected during measurement, measurement is canceled. 2 Fix the microphone for acoustical measurement (sold separately) in the center of the headrest of the driver's seat, facing forward. The Auto EQ may differ depending on where you place the microphone. If desired, place the microphone on the front passenger seat and perform Auto EQ. 3 Disconnect the iPhone or smartphone device. Chapter 4 Turn on the ignition switch (ACC ON). 24 If the vehicle's air conditioner or heater is turned on, turn it off. Noise from the fan in the air conditioner or heater may prevent correct Auto EQ. English 5 Switch the AV source to "OFF". For details of the operations, refer to Displaying the AV operation screen on page 12. 6 Press the HOME button to display the Top menu screen. 7 Touch the following keys in the following order. The "Audio" screen appears. 8 Touch [A-EQ&TA Measurement]. The "A-EQ&TA Measurement" screen appears. 9 Connect the microphone for acoustical measurement (sold separately) with this product. Plug the microphone into the microphone input jack on this product. 10 Touch [Front Left] or [Front Right] to select the current listening position. 11 Touch [Start]. A 10-second countdown starts. p The Bluetooth connection is discon- nected before the process starts. 12 Exit the vehicle and keep the doors closed until the countdown finishes. When the countdown finishes, a measurement tone (noise) is emitted from the speakers and the Auto EQ measurement begins. 13 Wait until the measurement is completed. When Auto EQ is completed, a message is displayed indicating that the measurement is completed. 65 En
