User manual JBL L46

[. . . ] CAUTION: To prevent electric shock, do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 1. 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. [. . . ] If you measured the distances in feet, don't multiply the result; it will be the same as the setting. 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 3m away and the surround speakers are 1m away, the optimal delay time is figured as (3 ­ 1) x 3 = 6. Thus, in this example, the delay time for Dolby Digital should be set at 6 milliseconds. If you measured the distance in feet instead of meters, don't multiply the difference by 3. Thus, if the front speakers are 10 feet away from the listening position, and the surround speakers are 4 feet away, then the difference will be 10 ­ 4 = 6, and the Dolby Digital delay should be set at 6 milliseconds. When setting the delay time for any Dolby Pro Logic II mode, take the result of the calculation above and add 15 to obtain the optimal delay time. For example, if the front speakers are 3m away and the surround speakers are 1m away, the optimal delay time is figured as (3 ­ 1) x 3 + 15 = 21. Thus, in this example, the Pro Logic II delay should be set at 21 milliseconds. Similarly for English measurements, if the front speakers are 10 feet away and the surround speakers are 4 feet away from the listening positon, then the delay for the Dolby Pro Logic II modes is calculated at 10 ­ 4 = 6 + 15 = 21 milliseconds. NOTE: The DTS, 5CH Stereo, Hall and Theater modes use a fixed, nonadjustable delay time. MAX: When MAX is shown in the display, a more severe compression algorithm will be applied. When you want to use the Night mode feature, we recommend that you select the MID setting as a starting point and change to the MAX setting later, if desired. When the MID or MAX setting is selected, the NIGHT Mode Indicator L will light. To confirm the selection, press the Set Button E^ or wait for several seconds until the display returns to the normal mode. Output Level Adjustment Output level adjustment is a key part of the configuration process for any surround sound product. It is particularly important for a Dolby Digital receiver such as the L46, as correct output levels will ensure that you hear soundtracks with the proper directionality and intensity. NOTE: Listeners are often confused about the operation of the surround channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambience, a special effect or to continue action from the front of the room to the rear. When the output levels are properly set, it is normal for surround speakers to operate only occasionally. Artificially increasing the volume to the rear speakers may destroy the illusion of an enveloping sound field that duplicates the way you hear sound in a movie theater or concert hall. IMPORTANT NOTE: The output level can be adjusted for each digital and analog surround mode separately.
