THX Ultra2 Subwoofer Setup

With a THX Ultra2 subwoofer (or one that has a response to 20Hz), depending on the position of the subwoofer and the walls in your listening area, you may experience overly resonant frequencies in the bass. If you have this problem use the THX Ultra2 subwoofer setup to switch on boundary gain compensation (see About THX® on page 101 for more on this).

Note

•If you don't have a subwoofer, you won't be able to select this setting.

•Selecting YES in step 2 (below) cancels the setting you made for Bass Peak Level on page 86.

1Select ‘Ultra2 SW Setup’ from the THX Audio Setup menu.

2Specify whether your subwoofer is THX Ultra2 certified (or can respond to 20Hz).

You can only switch on Boundary Gain Compensation (below) if you have selected YES for this setting.

3Select either ON or OFF for the Boundary Gain Compensation setting.

4When you're finished, select RETURN and press

ENTER.

You will return to the THX Audio Setup menu.

Surround Back Speaker Position

For the most effective results when using the THX Ultra2 Cinema and THX MusicMode listening modes (see Using the Home THX modes on page 41) with the Advanced Speaker Array (ASA) system (see About THX® on page 101), it is required that you make the setting below.

Note

•If you don't have surround back speakers, or just have one, you won't be able to select this setting.

1Select ‘SB SP Position’ from the THX Audio Setup menu.

2Specify the distance of your surround back speakers from each other.

•0.0–0.3 m – Surround speakers up to 30 cm apart (best for THX surround sound).

•<0.3–1.2 m – Surround speakers between 30 cm and 1.2 m apart.

•1.2 m< – Surround speakers more than 1.2 m apart.

3When you're finished, select RETURN and press

ENTER.

You will return to the THX Audio Setup menu.
