Adjusting The Speaker Balance; Before You Start Adjusting; Using The Test Tone - Yamaha RX-V420RDS Owner's Manual

This procedure lets you adjust the sound output level
balance between the main, center and rear speakers by using
the built-in test tone generator. When this adjustment is
performed, the sound output level heard at the listening
position will be the same from each speaker. This is
important for the best performance of the digital sound field
processor, the Dolby Pro Logic decoder, Dolby Digital
decoder and DTS decoder.
Note
• Since this unit cannot enter the test mode while headphones are
connected to this unit, be sure to unplug the headphones from the
PHONES jack when using the test tone.
