Why is there no sound coming from my Yamaha Amplifier?
If no sound is coming from your Yamaha Amplifier, first ensure all input/output cables are securely connected. Then, make sure the Mute function is off (the [MUTE] indicator should be unlit). Also, verify that an audio signal is being output from the mixer or other device. Check the attenuator value and make sure it is appropriate. If “Analog” input has been selected on a device that is connected via a YDIF connector, select “digital” input on the device or disconnect the device from the YDIF network. If the [PROTECTION] indicator is lit, turn off the power, wait for the XMV to cool, and then turn the power on again. If the [POWER] indicator is blinking, make sure that the switch connected to the [REMOTE] connector is turned on or use the editor to check that this is turned on. If the anal...
What to do if Yamaha Amplifier has no sound?
If you are experiencing no sound from your Yamaha Amplifier, consider the following potential causes and solutions: * Ensure the analog/digital input setting is correct by checking it on the front panel. * If Double Power mode is selected, no audio signals will be output from channel B or channel D. Either turn off Double Power mode or reconnect the cables. * Verify all input/output cables are connected securely. * Confirm the mute function is turned off by ensuring the [MUTE] indicator is unlit. * Check the attenuator value on the display to ensure it is appropriate. * Make sure an audio signal is being output from the mixer or other device. * If the protection circuit has operated (the [PROTECTION] indicator is lit), turn off the power, wait for the XMV to cool, and then t...
