Notes on installation of ceiling speakers
When installing presence speakers to a ceiling, install them just above the listening position,
or the ceiling between the extensions of the front speakers and listening position.
Caution
• Be sure to use speakers that are made for ceiling use and take anti-drop measures. Ask a qualified
contractor or dealer personnel for installation works.

Setting the speaker impedance
Under its default settings, the unit is configured for 8-ohm speakers. When using a 6-ohm
speaker for any channel, set the speaker impedance to "6 Ω MIN". In this case, you can also use
4-ohm speakers as the front speakers.
