JBL DVD600II, SCS135P Setting Delay Times, Seconds, To set the delay times, follow these steps

at the channel being adjusted to give you time to make the adjustment. When you release the button, the circulation will resume after

15 seconds.

5.Continue to adjust the individual speakers until they all have the same volume. Note that adjustments should be made with the

⁄ / ¤ Buttons y on the remote or the Selector Buttons 5 on the front panel only, NOT the main volume controls, except when setting the reference level of the front left speaker. If you are using a sound pressure (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB, C-Weighting Slow.

NOTE: The subwoofer output level is not adjustable using the test tone. To change the subwoofer level, press the Channel Select Button Óx while playing a favorite selec- tion, and use the ⁄ / ¤ Buttons y or Selector Buttons 5 to choose the subwoofer channel, followed by the Set Button ^ to select it, and then the ⁄ / ¤ Buttons y or Selector Buttons 5 to adjust the channel outputs to a desired level, and the Set Button ^ to memorize the change.

6.When you have adjusted the outputs so that all channels have the same level, press the Set Button pˆ to complete the adjust- ment.

NOTE: The output levels may be separately trimmed for each digital and analog surround mode. If you wish to have different trim levels for a specific mode, select that mode and follow the instructions in steps 2 through 5 above.

Setting Delay Times

Due to the different distances between the front-channel speakers and the listening posi- tion compared to the surround speakers and the listening position, the amount of time it takes for sound to reach your ears from the front or surround speakers is different. You may com- pensate for this difference through the use of the delay settings to adjust the timing to match the specific speaker placement and acoustic conditions in your listening room or home theater.

The factory setting is appropriate for most rooms, but some installations create an uncom- mon distance between the front and surround speakers that may cause the arrival of front-

channel sounds to become disconnected from surround-channel sounds.

To resynchronize the front and surround channels, follow these steps:

1.Measure the distance from the listening/ viewing position to the front speakers.

2.Measure the distance from the listening/ viewing position to the surround speakers.

3.Subtract the distance to the surround speakers from the distance to the front speakers.

a.When setting the delay time for the Dolby Digital surround modes, the optimal delay time is the result of that subtraction. For example, if the front speakers are 10 feet away and the surround speakers are five feet away, the optimal delay time is figured as 10–5=5. Thus, in this example, the delay time for Dolby Digital should be set at five milliseconds.

b.When setting the delay time for the Dolby Pro Logic II mode, take the result of the subtraction and add 15 to obtain the opti- mal delay time. For example, if the front speakers are 10 feet away and the sur- round speakers are five feet away, the opti- mal delay time is figured as 10–5+15=20. Thus, in this example, the Pro Logic II delay should be set at 20 milliseconds.

NOTE: The Theater and Hall modes use a fixed, nonadjustable delay time.

The Dolby Digital mode also includes a separate setting for the center channel delay mode, since the discrete nature of these signals makes the location of the center channel speaker more critical. To calculate the delay for the center channel, measure the distance from the preferred listening position in the center of

the room to both the center channel speaker and either the left or right speaker.

If the distances are equal, no further adjustment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker, you may wish to reposition the speakers by moving the front-left and front-right speakers closer to the listening position or the center speaker further away from the listening position.

If repositioning of the speakers is not possible, adjust the center delay time, adding one millisecond of center channel delay for every foot closer to the listening position the center speaker is than the front speakers. For example, if the front-left and front-right speakers are each 10 feet from the listening position and the center channel speaker is eight feet away, the delay is figured as 10–8=2, suggesting an opti- mal center delay of two milliseconds.

To set the delay times, follow these steps:

1.Put the DCR600II in the Dolby Pro Logic II mode by pressing the Surround Mode Selector 7 on the front panel or by pressing the Surround Mode Selector t on the remote, until DOLBY PRO LOGIC II – MOVIES appears in the Main Information Display U and the PRO LOGIC II Indicator

F lights up.

2.Press the Delay Button & on the remote or front panel. The words S DELAY TIME will appear in the Main Information Display U.

3.Press the Set Button ^.

4.Adjust the delay time by pressing the

⁄ / ¤ Buttons y on the remote or the Selector Buttons 5 on the front panel until the delay time figure calculated using the formula entered above appears in the display.

5.If only analog sources will be used, no adjust-

ment is needed for the center channel delay. In that case, press the Set Button ^ to enter the surround delay settings into the receiver’s memory. However, if you will be using digital sources and the calculations out- lined above indicate that the center channel delay requires an adjustment, continue with the following steps.

6.Before setting the center channel delay time, make certain that a digital source such as the DVD600II has been selected. If a digital source is playing, COAXIAL E or OPTICAL B will appear in the Main Information Display

(. If a digital source is already connected and playing, press the Delay Button & and then the ⁄ / ¤ Buttons on the remote

y or the front panel Selector Buttons 5 until the words C DELAY TIME appear in the Main Information Display U and proceed to Step 10. If a digital source is not playing, follow Steps 7 through 10.
