SYSTEM CONFIGURATION 6.1-Channel System Video Screen Center Speaker Front Left Speaker 30° Front Right Speaker 30° 110° 110° Side Surround Left Speaker Listening Position Side Surround Right Speaker Back Surround Speaker Surround Speakers for 6.1 Systems A 6.1 surround speaker adds an additional center back surround speaker to the system, enabling you to enjoy the benefits of advanced surround modes such as Dolby Digital EX, DTS-ES and Harman Kardon's proprietary Logic 7/7.1 processing. To step up to a 6.1 system, first place the speakers for a 5.1 system, as shown on page 14. The "sixth" speaker should ideally be placed at the center of the room's rear wall, pointing directly towards the front center channel speaker. IMPORTANT NOTE: It is not possible to configure the AVR 140 for 7.1-channel operation. Do not connect more than one speaker to the Surround Back Speaker Outputs ¶, as doing so may damage your speakers, the AVR 140 or both. When 7.1-channel information is received, for example through the 6/8-Channel Direct Inputs g, or when deriving 7-Channel Stereo or Logic 7/7.1 surround information, the AVR 140 combines the left and right surround back channel information and outputs it as a single surround back channel. Since subwoofers produce nondirectional sound, they may be placed almost anywhere in a room. Actual placement should be based on room size and shape and the type of subwoofer used. One method of finding the optimal location for a subwoofer is to begin by placing it in the front of the room, about six inches from a wall, or near the front corner of the room. Another method is to temporarily place the subwoofer at your normal listening position, and then walk around the room until you find a spot where the subwoofer sounds best. Place the subwoofer in that spot. You should also follow the instructions of the subwoofer's manufacturer, or you may wish to experiment with the best location for a subwoofer in your listening room. NOTES ON SPEAKER PLACEMENT: 1. The limitations of your listening room, including the placement of walls and furniture, may make it difficult to follow the speaker placement suggestions shown above. Depending on the specific layout of the room, here are some ways to compensate for unusual conditions: • Try to follow the suggested placement, but move the speakers within a few feet from the preferred locations. • Regardless of where they are placed, always try to make certain that the main surround speakers are the same distance from the front speakers. (For example, try not to have the right surround speaker further back into the room than the left surround speaker.) • If it is not possible to wall-mount or place speakers on a shelf, consider the use of optional floor stands, available for many speakers. 2. When using ceiling mounted in-wall speakers, follow the same guidelines shown for conventional floor or shelf-mounted speakers. System Setup Once the speakers have been placed in the room and connected, the remaining steps in the setup process are to configure each source input to match the physical connections you have made, select a surround mode, program the AVR 140's bass management system for the type of speakers used in your system, calibrate the output levels, and set the delay times used by the surround sound processor. You are now ready to power up the AVR 140 to begin these final adjustments. 1. Make certain that the AC Power Cord ‹ is firmly inserted into an unswitched AC outlet. To maintain the unit's safety rating, DO NOT replace the power cord with one that has a lower current capacity. 2. Press the Main Power Switch 1 in until it latches and the word "OFF" on the top of the switch disappears inside the front panel. Note that the Power Indicator 2 will turn amber, indicating that the unit is in the Standby mode. 3. Remove the protective plastic film from the frontpanel lens. If left in place, the film will affect the performance of your remote control. 4. Install the three supplied AAA batteries in the remote as shown. Be certain to follow the (+) and (-) polarity indicators that are on the top of the battery compartment. 5. Turn the AVR 140 on either by pressing the Standby/On Switch 2 on the front panel, or via the remote by pressing the Power On Button d, the AVR Selector f or any of the Input Selectors degde on the remote. When the unit is turned on, the entire list of options will briefly light for both the Input Indicators Ú and the Surround Mode Indicators ˆ. After a few seconds, most of SYSTEM CONFIGURATION 15
