place itself in the Standby mode, depending on whether it is receiving an audio signal. When this switch is placed in the ON position, the SUB-TS18 will remain on, whether or not it is receiving an audio signal.
An LED located on top of the SUB-TS18 indicates whether the SUB-TS18 is in the On or Standby state when used with the Audio- Sense On/Off Switch ¢ in the AUTO position. The LED is lit blue to indicate that the SUB-TS18 is receiving an audio signal and is turned on, and the LED is lit amber to indicate that no signal is being received and the SUB-TS18 is in the Standby mode.
When the Audio-Sense On/Off Switch ¢ is in the ON position, the LED will be lit blue, whether or not an audio signal is present.
When the Master Power Switch ‚ is turned off, the LED goes dark, no matter which position the Audio-Sense On/Off Switch ¢ is in.
∞Phase Switch: This switch determines whether the SUB-TS18 subwoofer’s piston- like action moves in and out in phase with the main speakers. If the speakers were to play out of phase, the sound waves pro- duced by the subwoofer would be canceled out, reducing bass response. This phenome- non depends in part on the relative place- ment of the speakers in the room. In most cases, the Phase Switch ∞ should be left in the NORMAL position. However, it does no harm to experiment with the Phase Switch ∞, and you may leave it in the position that maximizes bass response.
§Line-Level Subwoofer (SUB) Input: Connect the subwoofer output of a receiver with digital surround sound decoding, such as Dolby® Digital or DTS®, to this input. This input bypasses the SUB-TS18’s internal crossover circuitry, and should only be used with a filtered signal. If your receiver does not have digital decoding, you should use the Line-Level Full-Range Inputs ¶ instead.
¶Line-Level Full-Range Inputs: Connect the line-level subwoofer output or preamp out- put(s) of your receiver or amplifier to these inputs. If your receiver does not have a sepa- rate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver’s preamp out- put to the main amp input for that channel, and connect the long end of the adapter
to the corresponding line-level input on the SUB-TS18. If your receiver has only a single subwoofer output, you may connect it to either the left or right line-level input on the SUB-TS 18, and no Y-adapter is needed.
•Speaker-Level Outputs: If you are using the Speaker-Level Inputs ª on the SUB-TS18, you should connect these binding- post terminals to your front left and right speakers, remembering to maintain polarity by connecting the (+) terminal on the SUB-TS18 subwoofer to the (+) terminal on the speaker, and the (–) terminal on the SUB-TS18 subwoofer to the (–) terminal on the speaker. If you are not using the Speaker-Level Inputs ª, then connect your front left and right speakers directly
to your receiver or amplifier. See pages 9 through 12 for further information on speaker connections.
ªSpeaker-Level Inputs: If your receiver or amplifier does not have a line-level sub- woofer output, connect these binding-post terminals to the main left and right speaker terminals of your receiver or amplifier. Remember to maintain polarity by connecting the (+) terminal on the receiver/amplifier to the
(+) terminal on the SUB-TS18 subwoofer, and the (–) terminal on the receiver/amplifier to the
(–) terminal on the SUB-TS18 subwoofer.
‚Master Power Switch: Place this switch in the “•” position to power-on the SUB-TS18 subwoofer. The SUB-TS18 will then be either in the Standby mode or com- pletely on, depending on the position of the Audio-Sense On/Off Switch ¢.
⁄AC Power Cord: Make sure to plug this cord into an active, unswitched electrical out- let for proper operation of the SUB-TS18.
The cord should not be plugged into the accessory outlets found on some audio components.
