20SETTING UP YOUR D 200 continued
CENTER SPEAKER
This may be set to LARGE, SMALL or NONE. Set to LARGE or SMALL, according to the guidelines in the previous paragraphs. Set to NONE if your home theater has no center channel speaker. The D 200 will blend the center channel signals into your front left and right front speakers. This creates a “Phantom” center channel sound image because the center channel sound will appear to come from the middle space between your left and right front speakers, even without an actual center channel speaker.
SURROUND L&R
These are the speakers that are placed at the sides of your room. This may be set to LARGE, SMALL or NONE. Set to LARGE or SMALL, according to the guidelines above. If you select NONE the surround channel signals are blended into the front channels.
CROSSOVER
This sets the subwoofer bass filter’s cutoff frequency from 70 Hz to120 Hz, in 10 Hz increments and from 120 Hz to 160 Hz, in 20 Hz increments. The optimum setting will depend on your speakers, your sub, and your room’s acoustics. The best starting point is 80 Hz. Don’t use both the crossover filter in your sub and the Crossover filter in the D 200, or some bass frequencies you want may not be heard at all. If your subwoofer doesn’t have a bypass switch for its crossover filter, adjust it to its highest frequency setting to minimize redundant filtering. If your sub has a fixed filter and no bypass, set the D 200 Sub filter to 160 Hz.
DISTANCE SETUP
Use the DISTANCE SETUP menu to calibrate the arrival time for the sound from each speaker. Convincing surround sound depends on the sound reaching your ears from each speaker at the same time as the recording engineer intended. For example, if your front speakers are three feet further from you than your surrounds are, the sound from the front speakers will reach you about
3 milliseconds (0.003 sec.) later than the surrounds and you might hear, say, an echo before the shot itself. To compensate for your speaker placement, your D 200 can delay the sound from the surround speakers by three milliseconds, restoring the correct timing. You can set delays by measuring the distance from each speaker to your head when you’re seated in your favorite viewing/listening position and entering it in the
DISTANCE SETUP.
Use a measuring tape and note the distance from your primary listening position to each speaker. The D 200 will translate each foot (.34 meters) of distance for a given channel into 1ms (millisec- ond) of delay. For each speaker, the distance can be set in
Note: You cannot set distance for any speakers set to NONE or NO in the SPEAKER SIZE setup page.
