system planningProper system planning is the best way to maximize your PowerPlate’s™ performance. By planning yourinstallation carefully you can avoid situations where the performance or the reliability of your system iscompromised. Your authorized a/d/s/ dealer has been trained to maximize your system’s sonic potential.Your a/d/s/ dealer is a valuable resource in helping you with your system design and installation.speaker requirementsEach channel of your PowerPlate™ caneasily drive 2Ω speaker loads when used inthe stereo mode. When a channel-pair isbridged, the recommended minimum loadimpedance is 3Ω for subwoofer use, and 4Ωfor full range operation. Although operationwith lower impedances is not likely to causeimmediate damage to the internal circuitry,the unit will most likely overheat, causing thethermal protection circuitry to shut down theamplifier. When the chassis cools down,normal operation will resume. Continuing tooperate the amplifier under these conditionsis not recommended and will reduce its lifeexpectancy.Most speakers designed for car audiooperation are 4Ω impedance. Connectingtwo such speakers in parallel will result in a2Ω impedance load as seen by the amplifier.Some a/d/s/ subwoofer models feature adual 4Ω voice coil design. Connecting thesevoice coils in parallel will result in a 2Ωnominal impedance, which is notrecommended for use with bridged channelsof your PowerPlate™.system configurationsAll a/d/s/ PowerPlates™ provide extensive features, which make a variety of system configurationspossible. It is not feasible to cover all of the possibilities within the few pages of this manual. There are afew system configurations, however, which are extremely popular when used alone or as a "buildingblock" of a larger more elaborate system. Please review systems 1 through 4 as described below forsuggestions on how to configure the most popular combinations.button is disengaged control is non-operationalbutton is engaged control is operational4
