[. . . ] For optimal enjoyment a subwoofer should be used as it is optimized for low frequency reproduction. If you have large full range front speakers, however, they may be used in place of a subwoofer with proper setting of the rear panel switches. For the best advice on speaker selection consult your Harman Kardon dealer. When you have the information on your speakers, set the four switches as follows: 1) Front Speaker Mode This switch determines the frequency range of the front left/right speakers. Select Large or Small depending on the type of speaker you will be using. Large: Set the switch to this position if you are using full range speakers that are capable of reproducing sounds below 100 Hz. In this position, the output to the front left/right output jacks is full range. This switch position should also be used if you are using a packaged speaker system where the first input feed is to the subwoofer. Although subwoofer/satellite systems normally use the "small" setting, some systems contain a crossover within the subwoofer, and send filtered sounds to small speakers. Consult your dealer or the speaker system's owner's manual if you are uncertain if this is an appropriate setting. Small: Set the switch to this position if you have small, frequency limited satellite type speakers that do not reproduce sounds below 100 Hz, and whenever a subwoofer is used. Use this setting if you have a subwoofer satellite system where there are separate feeds to your subwoofer and the small satellite speakers (but then an extra subwoofer is neccessary for the LFE channel). When the Subwoofer Mode Switch ª is in the "ON" position, front Low Frequency Effects (LFE) audio will be routed to the subwoofer. 2) Surround Speaker Mode This switch determines the frequency range of the rear surround speakers. Select Large, None or Small depending on the type of speakers you will be using. The factory default setting is "Small". SPEAKER MODE SETTINGS Since the ADP303 may be used with a wide variety of speaker types, it is important that you adjust the rear panel speaker mode switches before use. Setting these switches will tell the ADP303 what type of speakers you are using so that the audio outputs will be directed to the proper speaker. In general, a "Large" speaker is defined as a traditional full range speaker that includes a woofer or some prepackaged "satellite/subwoofer" systems and is capable of reproducing sounds below 100 Hz. For the purposes of this product, a "Small" speaker is one that is not capable of delivering sounds significantly below 100 Hz. (Most "satellite" type speakers fall into this category. ) Before setting the switches make note of the type of front, center and rear speakers that will be used. For further clarification of your speakers' type consult the speaker owner's manual and look on the "specifications" page to find the frequency range. SPEAKER SELECTION The home theater system you already have installed should work with the ADP303 provided that there are left, center and right front speakers, left and right rear/surround speakers and a subwoofer. For best results we recommend that the front speakers be of the same type, with identical or similar driver units. This will deliver smooth pans across the front sound stage as the action moves from side to side. 24093_ADP 303 Eng. [. . . ] Note that the AC-3 indicator will illuminate when the unit is locked to the digital signal and is functioning properly. Depending on the equipment in your specific home theater installation, you will use either the volume control on your AVR80 or "6 Channel Equipped" receiver, or the front panel volume control on the ADP303 î. · When the ADP303 is used with the AVR80 or another product with a 6 Channel Direct mode make the appropriate input selection on the receiver. Make certain that the ADP303 front panel volume control î is set to the 12 o'clock position. [. . . ]
