105.2 Controls on the rear panela) ModeThis push button allows you to choose between• Signal On: woofer starts operation as soon as a musicalsignal arrives, and stops after 15 minutes without a signal.• Continuous: the unit is permanently working.We recommend the ”Signal on” position. It minimisespower consumption and makes handling very easy.b) Subwoofer PhaseWith the Phase Switch you can alter the phase of thesubwoofer relative to the satellites. That means to changethe polarity of the bass unit. Depending on the distancebetween woofer and satellites, either 0° or 180° maybe the better position. We recommend to try out whatposition sounds better within your system.c) Satellite FilterThe satellites in a system can be driven full range or with a85 Hz high pass as recommended by Dolby® laboratoriesfor use in surround set-ups. Recommendation: If possiblethe main signal should go into the Subwoofer. Connectyour satellites to the Subwoofer output, either via XLRsymmetrical or RCA asymmetrical. In many cases, clarityand dynamic range of the speakers can be improved ifthey do not reproduce very low frequencies since they donot have to deliver big amplitudes.5. Controls
