2 Basic system layout (For a THX Ultra2 system)
• The following is an example of the basic layout for a system consisting of eight speaker systems and a television monitor:
Subwoofer Center speaker system
Surround speaker systems
Surround back speaker systems
Front speaker systems
Set these at the sides of the TV or screen
with their front surfaces as flush with the
front of the screen as possible.
Two surround back speakers are required to use the THX Ultra2 Cinema,THX Music mode and THX Games mode.
Set the surround back speakers so that the distance to the listening position is the same for both the left and right speakers. It is
also recommended that the deviations of the distance from the listening position to L and R channel speakers (front left (FL) and
front right (FR), surround left (SL) and surround right (SR), surround back left (SBL) and surround back right (SBR)) is less than 2
ft (60 cm).
With the AVR-5805CI it is also possible to use the surround speaker selector function to choose the best layout for a variety of
sources and surround modes.

2 Surround speaker selector function
This function makes it possible to achieve the optimum sound fields for different sources by switching between two
systems of surround speakers (A and B). The settings of the different speakers (A only, B only or A+B) are stored in the
memory for the different surround modes, so they are set automatically when the surround mode is selected.
