User manual MIRAGE SPEAKERS BPS210

[. . . ] Grounding or Polarization - This product may be equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. · · · 1 BPS-400 · owners manual Power Cord Protection - Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product.

Non-use Periods - The power cord of the product should be unplugged from the outlet when left unused for a long period of time. Damage Requiring - The product should be serviced by qualified service personnel when: A The power-supply cord or the plug has been damaged; or B.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. CAUTION: MIRAGE SUBWOOFERS HAVE A BUILT-IN AMPLIFIER AND MUST HAVE ADEQUATE VENTILATION FOR COOLING PURPOSES. DO NOT PLACE THE SUBWOOFER NEAR HEAT SOURCES, OR ANYTHING WHICH MIGHT OBSTRUCT VENTILATION. Although a clear path between the subwoofer and listening position is not required, it is important to leave approximately 4 inches of clearance between the subwoofer and walls or room furnishings. Generally, shorter runs of hook-up cables are preferable (and easier to hide), therefore locating your subwoofer relatively close to your audio equipment is often desirable. The interaction between room acoustics and any subwoofer is closely related to the subwoofer's proximity to the walls. Typically, subwoofer placement directly in or close to a corner will produce the most bass output, placement along one wall but away from a corner will produce less bass output, and placement of the subwoofer further into the room will produce the least amount of bass output. It should also be realized that the corner location, although producing the most bass output often yields ill-defined or "boomy" bass. The latter two locations will deliver progressively more accurate bass performance. SUBWOOFER SUBWOOFER SUBWOOFER MOST BASS OUTPUT, BUT MAY BE "BOOMY". MODERATE BASS OUTPUT WITH SMOOTHER PERFORMANCE. LESS BASS OUTPUT, BUT WITH BEST PERFORMANCE. We urge you to experiment with various subwoofer placements in your listening room to find the position which produces "deep and smooth" performance. Often, moving the subwoofer a foot or two can make a big sonic improvement. Remember to use familiar musical recordings with an abundance of low frequency information when you experiment with subwoofer locations. 6 owners manual BPS-400 CONNECTING YOUR SUBWOOFER Using an Integrated Amplifier/Receiver equipped with pre-out Jacks only (See Diag. 1) This method uses two standard RCA-to-RCA interconnect cables. First, connect the amp/receiver's left "PRE-OUT" to the subwoofer jack marked left (L) "LOW LEVEL INPUT". Then, connect the amp/receiver's right "PRE-OUT" to the subwoofer jack marked right (R) "INPUT". This method by-passes the subwoofer's built-in high pass crossover, and your speakers will continue to reproduce bass frequencies. Using the "Subwoofer Output" of an A/V Receiver or Processor (See Diag. 2) This method uses a single RCA-to-RCA interconnect cable to connect the "SUBWOOFER OUTPUT" jack from your A/V receiver or processor to either the left or right subwoofer "INPUT". This method does not remove low frequencies from your main speakers, and they will continue to reproduce bass frequencies. Using External Crossover (See Diag. [. . . ] Set the Subwoofer Level to its zero position. Set the Subwoofer Roll-off Frequency Control to 50Hz. Set any loudness, bass/treble, and/or equalizer controls on your preamplifier or integrated amp/receiver to their normal or mid-point positions. Play a familiar CD, record, or video soundtrack that has substantial bass content. [. . . ]
