User manual BOSTON ACOUSTICS HPS 12HO

[. . . ] Maintain a minimum distance of 2" (50mm) around the front, rear, and sides of the apparatus for sufficient ventilation. The ventilation should not be impeded by covering the ventilation openings or placing on or around the apparatus items such as newspapers, table-cloths, curtains, etc. No objects filled with liquids, such as vases, shall be placed on the apparatus. Either the power inlet connector on the rear of the apparatus or the power plug at the wall must remain accessible, to be able to disconnect power from the apparatus. [. . . ] The foot on the rear of the subwoofer can be removed to produce a slight backward tilt. IMPORTANT: Do not place the subwoofer where there is a chance of contact between the rear panel and drapes or furniture. After your speakers are properly placed, you are ready to wire your system. NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged or switched to the off position using the power switch located on the rear panel. The auto-on circuitry only activates or deactivates the power amplifier. Make sure your subwoofer and receiver are unplugged when making the connection. Power: When plugging your subwoofer in be sure to use a wall outlet, or dedicated electrical outlet. These on board electrical outlets do not offer the amount of current or proper isolation required by a power amplifier, such as the one in your amplifier. Line level or LFE: On most systems use the line level input or the LFE input. These inputs accept the line-level signal from your receiver's subwoofer output. Your receiver's manual should indicate which input is most appropriate. Hooked up this way, the receiver's amplifier is relieved of having to reproduce the difficult low bass signals that can drive the receiver into audible distortion. In some cases it can also depend on several other settings within a receiver. We recommend consulting your receiver manual for further assistance in this area. Use an RCA cable (not included), as shown, to connect your digital receiver's LFE subwoofer output to the subwoofer. For stereo or Dolby Pro Logic systems use the "sub out" connection from your receiver to the input on the subwoofer marked "Left" and "Right". If the electronic in your system does not have a subwoofer of LFE output you can connect the HPS units to a preamp output. As a starting point, set the crossover control on the subwoofer about 10Hz higher than the lower limit of your main speakers' bass response. Fine -tune the crossover setting by ear for the smoothest blend with your main speakers. You may want to turn your subwoofer off if you will not be using it for some time or wish to conserve electricity. If no signal is detected after several minutes, it will automatically enter the Standby mode. An LED indicator between the Power switch and the Polarity switch indicates what mode the subwoofer is in. [. . . ] For EU Customers Only This symbol found on the product indicates that the product must not be disposed of with household waste. Instead, it may be placed in a separate collection facility for electronic waste or returned to a retailer when purchasing similar product. Doing this contributes to reuse and recycling, minimizes adverse effects on the environment and human health and avoids any fines for incorrect disposal. Line level (nivel de línea) o LFE (BF): en la mayoría de sistemas, utilice la entrada LFE (BF) o line level de entrada (nivel de línea de entrada). [. . . ]
