PREPARATIONS

Caution

Under its default settings, the unit is configured for 8-ohm speakers. When connecting 6-ohm speakers, set the unit’s speaker impedance to “6 Ω MIN”. In this case, you can also use 4-ohm speakers as the front speakers. For details, see “Setting the speaker impedance” ().

Functions of each speaker

Speaker type	Function
Front (L/R) 1 2	Produce front left/right channel sounds (stereo sounds).
Center 3	Produces center channel sounds (such as movie dialogues and vocals).
Surround (L/R) 4 5	Produce surround left/right channel sounds. Surround speakers also produce surround back channel sounds when no surround back speakers are connected.
Surround back (L/R) 6 7	Produce surround back left/right channel sounds.
Front presence (L/R) E R	Produce CINEMA DSP effect sounds or heights channel sounds of Dolby Atmos and DTS:X contents.
Subwoofer 9	Produces LFE (low-frequency effect) channel sounds and reinforces bass parts of other channels. This channel is counted as “0.1”. You can connect 2 subwoofers to the unit and place them on the left/right (or front/rear) sides of the room.

We recommend using front presence speakers to have a full effect of the 3-dimensional sound fields. However, the unit creates Virtual Presence Speaker (VPS) using the front, center and surround speakers to produce 3-dimensional sound fields even when no front presence speakers are connected ().
Use “Ideal speaker layout” (diagram on the left) as reference. You do not need to exactly adjust the speaker layout to this diagram since the YPAO function of the unit will automatically optimize the speaker settings (such as distances) to suit the speaker layout.
