7. Compression

This feature allows you to compress the dynamic range of the sound which may be helpful for low volume listening late at night. Turning this feature off will permit full dynamic range. When turned on, louder passages are softened and softer passages are increased to maximize intelligibility of speech. Use the SELECT button to toggle between on and off.

8. Status Display

Press the SELECT button to toggle between STATUS DISPLAY ON and OFF. When turned on, an OSD appears for 2 seconds each time you press a button. This OSD appears only when using the “main out” composite or S-Video outputs. The selected INPUT<SURROUND MODE and VOLUME LEVEL will be displayed.

9. DVD Audio Full Range

This setting applies only to the 7.1 “analog pass through” input. Use the SELECT button to toggle between “yes” and “no”. When “yes” is selected, all signals present at the input will be sent to the output and be affected ONLY by the VOLUME control. When “no” is selected, the filters are defined by the “SPEAKER SIZE” settings chosen in Step1. Channels set to “large” will receive a full bandwidth signal while channels set to “small” will have limited low frequency response (80Hz filter). The analog filters will remove the low bass frequencies from the signal and redirect it to the subwoofer.
