Surround and THX Modes Applicable to the Various Software
Available Surround modes and THX modes vary depending on the speaker settings and the incoming signals.
The tables from this page to the next page show the relation of the Surround/THX modes and the incoming signals (with the Zone 2 speakers,
surround back speakers, and 7.1-channel reproduction mode settings).
• If only front speakers are activated, you cannot use the THX modes and the 7.1-channel reproduction mode (ES/EX/7.1).
• The numbers inside the parentheses under the incoming signal type indicate the number of the front channels and that of the surround
channels. For example, (3/2) indicates that the signals are encoded with three front signals (left/right/center) and two (stereo) surround
signals.
