This menu, also reached from the MAIN screen, adjusts the rela- tive volume level of all six speakers. Just as you set the delays in the previous step to ensure that the sound from all of the speakers arrives at the same time, you also need to ensure that the volume of the sound from all speakers is the same.

To calibrate levels, turn on the built-in noise generator by high- lighting the NOISE line of the BALANCE SETUP menu and use the VOL DOWN/UP buttons to choose the AUTO position. You will hear noise coming from the first speaker. After three seconds with no adjustment , the test signal will automatically shift to the next speaker, continuing through all of the speakers in sequence.

While seated in the normal listening location, listen to hear if one speaker is significantly louder or quieter than the others. It is best to identify a speaker that is in the middle range (neither the loud- est nor the quietest) to use as a reference.

Leaving the volume level of the reference speaker unchanged, cycle through the other speakers, this time adjusting each of their volume levels up or down to match the reference speaker, using the VOLUME DOWN/UP buttons to change the volume of the high- lighted speaker while the test noise is coming from it. Alterna- tively, you can switch to the MANUAL noise setting which will send the noise signal to the speaker you highlight on the menu.

Continue through all of the speakers until they produce the same output level. It may be necessary to cycle through the speakers, adjusting volumes several times to get the desired result.

It is also possible to adjust the balance with an external signal, such as a test signal disc. In this case, turn the noise setting to OFF and proceed directly to volume settings of individual speakers.

Note: This calibration will be more accurate using a sound pres- sure level (SPL) meter to measure the output of each speaker. SPL meters are available from electronics stores, or your authorized Rotel dealer may loan you one. Set the meter to its SLOW re- sponse with C-weighting and hold it away from your body. Adjust each speaker so that the meter provides the same reading for each of the speakers in your system. Use the MANUAL noise set- ting. For the most accurate calibration of a surround system, an

SPL meter must be used and all speakers must be calibrated to produce a 75 dB reading at the listening position.

Once you have completed the balance settings for all of your speakers, return to the MAIN menu by pressing the BACK button.

This menu, also reached from the MAIN screen, allows you to op- timize the RSP-985 for your particular subwoofer. The settings in this menu may be considered to be “advanced” and need not be adjusted unless specifically desired.

SW LIMITER: The wide dynamic range and impressive bass ef- fects of today’s source material can overload a subwoofer. This setting allows you to limit the level of the signal sent to the subwoofer. Go to the limiter menu by highlighting the SW LIMITER line and pressing ENTER. An instruction menu appears and a low frequency noise signal is sent to the subwoofer (or LARGE speak- ers if no subwoofer is present). Adjust the noise level with the VOL buttons until you just begin to hear distortion from the speakers. Press the ENTER button to set the limiter at this level. Press BACK to return.

STEREO/P/L SW: This setting allows you to override the standard bass management in STEREO, PRO LOGIC, and DSP MUSIC modes when LARGE front speakers are selected. Select YES to have a subwoofer active with LARGE front speakers in these modes. Se- lect NO if you don’t have a subwoofer. Select NORMAL for the standard automatic bass management in all modes.

LFE MIX LEVEL: This setting determines the relative signal level of the LFE (Low Frequency Extension) channel (the .1 channel) rela- tive to the five full-range channels. It is factory set according to the standards of Dolby Labs, DTS Technology, and THX Lucasfilm. The adjustment may be varied for each surround mode according to personal taste, if desired.

The LFE content of DTS encoded movies is mixed differently than DTS encoded music. For DTS movies, the LFE MIX LEVEL should be set to 10dB for correct THX playback. For DTS music, the level should be set to 0db. THX should not be activated for music play- back. For Dolby Digital movies, the LFE MIX LEVEL should be set to 10db for proper playback in DOLBY DIGITAL and THX modes.

Once you have completed the subwoofer settings for all of your speakers, return to the MAIN menu by pressing the BACK button.
