Owner’s Manual

System Setup

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 others in your home. This function can also be used to provide compression for program material that may require enhancement of overall intelligibility (such as some older soundtracks).

Another feature provided by this option is the necessary peak limiting required to avoid signal overload when "down-mixing" functions are selected.

The second variable provides additional peak limiting to allow overall average program level to be increased by adding even more compres- sion 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 reduction is automatically included in the bitstream to ensure safe down-mixing.

13.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 compression to the signal. Depending on your family, neighbors, 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.

14.Press the button to select the Return to Main Menu option.

15.Press the SELECT or MENU button to return to the Main Menu, or press the MENU button twice to exit the menu system.

NOTE: Except for the input source and surround mode, the settings chosen during this input setup process are universal and apply to all sources. You will need to correctly set each digital source to the appropriate input and select a default surround mode for each source connected to your Model 950. Once you have completed these selec- tions, proceed to the next step: configuring your loudspeaker setup and calibrating your system.

Speaker Configuration

You are now ready to configure the 950 for your particular loudspeaker system. Before proceeding please read the following information carefully:

Speaker Placement

The best speaker placement for your particular room will depend on its size, furnishings, seating arrangement, the acoustical properties of the space, includ- ing wall type, coverings, and various other factors.

Due to the complex nature of these variables it is impossible to recommend any one-size-fits-all placement. You may well have to experiment with vari- ous placement options to determine the best configuration for your specific situation. Please note that, the configuration and placement of your speakers is critical for creating the best possible surround sound playback.

Here are some basic recommendations you should consider when positioning your speakers.

Front left, center and right speakers:

These speakers should be placed at the same relative height from the floor and a similar distance from any walls. Most speakers sound best when located with the tweeter at ear height when you’re seated. Typically, the further away from the walls the speakers are, the better they will sound.

Insure that the speakers are aimed at the listener’s ears within your chosen seating position.

Surround left and right speakers

Place these speakers so that their height is approximately 1 meter (3 feet) higher than that of the listener’s ears if feasible.

Surround back left and right speakers

These speakers are required for Surround EX, DTS-ES, DTS NEO:6 and Cirrus Extra Surround playback.

Place these speakers behind the listener so that the angle between each speaker and the listener is approximately 30 degrees.

Place these speakers so that their height is 1 meter (3 feet) higher than that of the listener’s ears.

Note on dipole surround loudspeakers: Most dipole surround speakers have an arrow which indicates their proper orientation rela- tive to your video display/screen. Dipoles placed on side walls should have the arrows pointing forward. Dipoles placed on a rear or back wall should have the arrows pointing towards each other to achieve the correct acoustical image in the room.

Subwoofer

Subwoofer placement can frequently be a trial and error affair as bass energy set up “standing waves” in most every room. These standing waves can cause areas with too much bass, areas with too little bass, and areas in between. You may have to move the subwoofer and or the prime listening area to improve the bass response. Be aware that every surface you place the woofer close to (one wall, floor, two walls in a corner) will increase the overall apparent bass in the room. But this can potentially lead to boomy and muddy sounding bass.

When connecting any speakers, be sure to read the instruction manuals that came with the product and check your power amplifier’s instruction manual for proper hook-up of the loudspeakers.
