setting. The unit cycles through the options in the following sequence:

no comp, dr comp1, dr comp2, dr comp 3, dr comp4

The night mode menu will disappear automatically approx- imately 5 seconds (a factory default, may be changed in OSD time out) after you make your selection.

There are two types of automatic compression control built into the Dolby Digital process. Compression makes the loud parts softer and the soft parts louder to reduce the difference between the two.

One type of compression is most useful for situations such as late night viewing of programs with a wide dynamic range (like many action movies) that might disturb oth- ers in your home. This function can also be used to pro- vide compression for program material that may require enhancement of overall intelligibility (such as some older soundtracks).

Another feature provided by this option is the neces- sary peak limiting required to avoid signal overload when "downmixing" functions are selected.

The second variable provides additional peak limiting to allow overall average program level to be increased by adding even more compression to the signal.

These two algorithms can provide sufficient overall gain reduction to allow even wide dynamic range soundtracks with very soft parts and very loud parts to maintain good audibility at low volume levels.

In most cases a minimum amount of dynamic range reduc- tion is automatically included in the bitstream to ensure safe downmixing. However, regardless if the user chooses to engage Night mode compression or not, the DSP auto- matically ensures safe downmixing regardless of the signal encoding.

Use the and buttons to select a dynamic range option you prefer for the Night setting.

no comp: This option leaves the compression at 0% change.

dr comp1: This option increases the compression by 25%.

dr comp2: This option increases the compression by 50%.

dr comp3: This option increases the compression by 75%.

dr comp4: This option increases the compression by 100%.

Each option increases the amount of Dynamic Range com- pression to the signal. Depending on your family, neigh- bors, circumstances, and the overall volume you wish to achieve, we recommend you start with DR COMP1 or DR COMP2 as your initial setting. You will have to experiment with program material and your personal preferences to determine what is acceptable and best for you.
