[. . . ] IMPORTANT SAFETY INSTRUCTIONS Read these instructions. Install in accordance with the manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus, (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] ON, OFF ASA (ADVANCED SPEAKER ARRAY) SETUP SPEAKERS SPEAKERS CUSTOM SETUP SYNTHESIS 7CH ASA ASA ON, OFF or SETUP · ASA is a proprietary THX technology to process rear channel signals to optimize the listening experience for THX Ultra2 listening modes, including THX UL2Cin, THX MUSIC, DTS THX UL2Cin, DTS THX MUSIC, 5. 1mc THX UL2Cin, and 5. 1mc THX MUSIC. Applied to film sources, ASA processing blends surround channel signals to optimize ambient and directional surround sounds. Applied to music sources, ASA processing places surround channel signals on a wide, stable rear soundstage. ASA processing is available when one of the THX ULTRA2 listening modes is activated and both side and rear speakers are present. The ASA parameter can be changed in any mode, but the change will have no effect unless the above conditions are met. To maximize the effectiveness of ASA processing, configure a 7. 1-channel speaker setup so the rear speakers are placed close together facing the center of the listening space. · · · Select APART if the distance between the rear speakers is greater than 4 feet (1. 2m). Select CLOSE if the distance between the rear speakers is greater than 1 foot (0. 3m), but less than 4 feet (1. 2m). Select TOGETHER if the distance between the rear speakers is less than 1 foot (0. 3m). BGC (BOUNDARY GAIN COMPENSATION) SETUP SPEAKERS SPEAKERS CUSTOM SETUP SYNTHESIS 7CH BGC BGC or SETUP Adjusts boundary gain compensation when the THX ULTRA2 SUB parameter is set to ON. · · Select ON to apply a high pass 55Hz filter to all Main Zone audio output connectors and listening modes. Select OFF, and no filtering is applied to the Main Zone audio output connectors and listening modes. 3-37 Setup You can use the remote control 7/5 button to toggle between 7and 5-channel playback. When you use the 7/5 button, the SDP-40HD automatically: · · · Activates ASA processing during 7-channel playback. Deactivates ASA processing during 5-channel playback. Switches between the 5. 1 THX ULTRA2 and THX, DTS THX ULTRA2 and DTS THX, or 5. 1mc THX ULTRA2 and 5. 1mc THX listening modes. JBL 3-38 SDP-40HD Setup CALIBRATING SPEAKER DISTANCES & OUTPUT LEVELS The SDP-40HD offers calibration of speaker distances and output levels. Calibration helps to ensure accurate output signal arrival time and level at the primary listening position. However, it is not a substitute for proper speaker placement. Before calibrating speaker distances and output levels: · Set crossover points for the Main Zone audio output connectors. Setting crossover points afterwards could invalidate calibrated output levels (the CUSTOM or THX SETUP menu can be used to set crossover points). Eliminate extraneous noise in the listening space, including conversation, air conditioners, and sounds that filter in through open doors and windows. Move or remove people or objects blocking the path between the microphones or SPL meter and the speakers. SPEAKER CALIBRATION PARAMETERS The table on the next page indicates the speaker calibration parameters that can be used to set speaker distances and output levels for the speakers connected to the corresponding Main Zone audio output connectors. These parameters are available on the speaker distance and output level menus shown throughout this section. · · SPEAKER DISTANCE PARAMETERS +0. 0 to 30. 0ft or 12. 0m Reflect the distance between the primary listening position and the speaker connected to the corresponding Main Zone audio output connector. OUTPUT LEVEL PARAMETERS -18. 0db to +12. 0dB Reflect the output level of signals sent to the speaker connected to the corresponding Main Zone audio output connector. 3-39 Setup LEVELS CALIBRATION SETUP SPEAKERS MANUAL JBL Selecting the SPEAKER SETUP menu LEVELS CALIBRATION option displays the LEVELS CALIBRATION menu, to manually calibrate speaker distances and output levels.
