Theater Compensation

Theater compensation provides special equalization within any of the selected DSP modes. Most theatrical soundtracks are mixed on large dubbing stages for play- back in large movie theaters. When these soundtracks are played back in your home, they may appear to have too much treble, sounding harsh and “bright.” Theater com- pensation modifies the audio signal to reduce these char- acteristics and make the soundtrack reproduction more natural sounding.

Theater compensation can be accessed from the main menu or the th-eq button on the remote control turns theater comp. on/off.

To turn on Theater compensation from the main menu:

1.Press the menu button to enter the main menu. The main menu appears on the front panel display and the OSD. The cursor on the OSD should be pointing to the input configuration menu and input config appears on the front panel display.

2.Press the button until system configuration is selected. The cursor on the OSD should be pointing to the system configuration menu and system config appears on the front panel display.

Dolby Pro Logic II Cinema and DTS-ES NEO:6 Cinema include a form of equalization of their own to address the same conditions. When using these modes the addition of theater compensation may cause excessive reduction of the upper frequencies. However, you may wish to experiment with different soundtracks to find what sounds best to you.

Important Note: Theater compensation is not recom- mended for music modes, as the equalization added is not normally needed.

Analog Level Input and Peak Indicator

Not all consumer products (CD players, DVD players, etc.) reach a 2V RMS output, therefore the analog input level needs to be adjusted to meet such requirement before being processed. Adjustments are made in 1dB steps from -15dB to +10dB and do not affect any of the analog direct inputs.

Should the input signal overload the analog to digital convertor, the word “peak” will start flashing after “anlg peak ind:” until the user turns down the input signal via the master volume knob or left/right selector (when in the system config menu).

The PLII Music parameter menu is used to adjust the panorama, dimension and center Width processing options when listening to music in the Dolby Pro Logic II surround mode. For a description of these options, see the section titled “surround format information.” The PLII parameter menu is shown on the following page.
