Audio Adjust

3-9. THX Setup

Select this Setup THX listening modes; the one that is currently set is the one that is modified. The parameters that can be set are shown in the table below.

		Parameter	Setting
			Initial value
a	RE-EQ (THX)	Off, On	On
b	Decoder (Analog/PCM)	PL II, Neo:6	PL II
c	THX Surround	Off, On	Auto
	(Dolby D)

a) Re-EQ

Re-EQ (re-equalization) takes the edginess or “brightness” out of your home cinema sound to compensate for the fact that sound mixed for theaters may sound too bright when played back through speakers in the home environment.

This can be set to either “On” or “Off.”

This parameter is only enabled for the THX listening mode. Also, this is set to “On” when the TX-DS797 is turned on.

b) Decoder

Select the decoding mode for THX processes.

PL II: Select for Dolby Pro Logic II Movie.

Neo:6: Select for DTS Neo:6 Cinema.

c) THX Surround EX (Dolby D)

This setting allows you to set whether or not Dolby Digital sources will be played back using THX Surround EX when a surround back speaker is connected.

Auto: Automatically outputs signals with EX-identifying signals using THX Surround EX.

On: Outputs using THX Surround EX regardless of whether or not the signal contains EX identifiers.

Off: Does not output using THX Surround EX regardless of whether or not the signal contains EX identifiers.

Mono Movie Setup/Enhanced 7 Setup/Orchestra Setup/ Unplugged Setup/Studio-Mix Setup/TV Logic Setup

When you set the parameters of this sub-menu and select Mono Movie, Enhanced 7, Orchestra, Unplugged, Studio-Mix, or TV Logic as the listening mode, the set parameters become enabled.

		Parameter	Setting
			Initial value
a	Front Effect	Off, On	On
b	Reverb Level	Low, Middle, High	Middle
c	Rever Time	Short, Middle, Long	Middle

a) Front Effect

Some live recordings contain acoustic reverberation. When you play these sources, more reverberation will be applied by the DSP, creating too much reverb effects and the sound loses frame or presence. In this case, set this setting to “Off.” No reverberation from the DSP will be applied to the sound output from the three front channels, so the sound source is be played as it is without any further reverberation.

b) Reverb Level

This parameter allows you to adjust the depth of acoustic reverberation to match the playback source material, the acoustics of your room, and such other factors.

Select from the three settings “Low,” “Middle,” and “High.”

c) Reverb Time

Adjust the reverb time to match the source being played back and the acoustics of the room. Select from the three settings “Short,” “Middle,” and “Long.”
