What does error 'E10: Internal Err' mean on my Yamaha Amplifier?
If your Yamaha Amplifier displays 'E10: Internal Err', it means there is no DSP response. Restart the unit, and then try the auto setup procedure again.
What does error E01: No Front SP mean on my Yamaha Amplifier?
If your Yamaha Amplifier displays 'E01: No Front SP', it means the front L/R channel signal(s) is(are) not detected. Make sure you have selected the front speakers using SPEAKERS A or B. Also, check the front L/R speaker connections to ensure they are properly connected.
Why does my Yamaha Amplifier say E08: No Signal during setup?
If your Yamaha Amplifier shows 'E08: No Signal', it means the optimizer microphone isn't detecting the test tones. First, check the microphone setting. Then, check both the speaker connections and their placement to ensure they are correct.
What does 'W1: Out of Phase' mean on my Yamaha Amplifier?
If your Yamaha Amplifier displays 'W1: Out of Phase', it means the speaker polarity is incorrect. Check the speaker connections to make sure they are properly connected. Note that this message may appear even when the speakers are connected correctly, depending on the speakers.
What to do if my Yamaha Amplifier displays error E02: No Surr. SP?
If your Yamaha Amplifier displays 'E02: No Surr. SP', it indicates that a surround channel signal is not being detected. Verify the surround speaker connections to ensure they are properly connected.
Why does my Yamaha Amplifier show 'E07: No MIC'?
If your Yamaha Amplifier displays 'E07: No MIC', it means that the optimizer microphone was unplugged during the auto setup procedure. Connect the supplied optimizer microphone to the OPTIMIZER MIC jack located on the front panel.
Why does my Yamaha Amplifier say 'No Setup Menu!'?
The Yamaha Amplifier displays 'No Setup Menu!' because no setup menu items have been selected. To resolve this, select at least one setup menu item.
What does 'E12: No Speaker' mean on my Yamaha Amplifier?
If your Yamaha Amplifier displays 'E12: No Speaker', it means all 9 speakers and 2 subwoofers are not connected. Check the speaker connections and placement.
What should I do if my Yamaha Amplifier shows 'E11: Complex Err'?
If your Yamaha Amplifier displays 'E11: Complex Err', it means that multiple errors have occurred. Check the speaker connections and placement to resolve this issue.
What does 'W3: Level Error' mean on my Yamaha Amplifier?
If your Yamaha Amplifier displays 'W3: Level Error', it means the difference in volume level between the speakers is excessive. Readjust the speaker installation, check the speaker connections, use speakers of similar quality, and adjust the output volume of the subwoofer.
