To connect the Klipsch R-100SW Subwoofer to your audio system, follow these steps:
1. Ensure that the subwoofer is unplugged from the AC wall outlet before making any connections.
2. Check if your surround receiver or pre-amplifier has a line-level subwoofer output labeled Subwoofer Pre Out, Sub Out, SW Out, etc. If it does, connect one end of a subwoofer cable to this output and the other end to the subwoofer's line input labeled LEFT/LFE. This connection allows the subwoofer to operate with both music and surround sound movies. Refer to your receiver manual for specific instructions.
3. If your receiver does not have a subwoofer output, you can use an alternative hookup. Connect the Left and Right channel Pre-Amp Outputs from your receiver (if provided) to the Left/LFE and Right input on the subwoofer.
4. Set the crossover point on the subwoofer. If you have set the crossover point in the receiver, turn the Lowpass Filter xxxx on the subwoofer to the farthest point right (160Hz). Set the crossover point based on the size of your main left/right speakers. For larger floor standing speakers, set the crossover point between 50Hz-90Hz. For smaller bookshelf or satellite speakers, set the crossover point between 90Hz-150Hz. If your receiver does not have a crossover point setting, set the Lowpass Filter on the subwoofer within the same recommended settings.
5. Adjust the level of the subwoofer. If your subwoofer is connected to a Subwoofer Output of a surround receiver, set the subwoofer volume level control in the receiver to the halfway or 0 dB position. Then increase the volume or gain of the subwoofer until its volume level matches the output of your main speakers. If your subwoofer is connected to the L/R Pre-Amp Outputs of a receiver, there will be no subwoofer volume in that receiver to set before adjusting the subwoofer's gain control.
6. Use the Phase control to acoustically match the subwoofer's output to your main speakers. Select the position either 0° or 180° in which your subwoofer has more output at the listening position.
7. Set the Off/Auto/On switch according to your preference. In the Auto position, the subwoofer will automatically turn on when it senses a signal and go into standby mode after 15-20 minutes with no signal. In the On position, the subwoofer will remain on until manually switched to another setting. In the Off position, the subwoofer will remain off until the switch is manually turned back to Auto or On.
