ficiency and distortion. Engage this filter when using the Speaker-Level Inputs ª, or when using the Line-Level Full-Range Inputs ¶, unless your receiver or processor processes its line-level output using a lowpass filter. The filter has no effect when the
SUB Input § is used.
£ External Trigger Input: Use the supplied mini-plug cable to connect the trigger output of another product to this jack. When a trigger signal between 3 and 30 volts (AC

or DC) is detected, the SUB-TS11 amplifier will turn on, even when the Audio-Sense feature has been activated by placing the
Audio-Sense On/Off Switch ¢ in the
AUTO position. The amplifier will remain on for about 10 –15 minutes without an audio signal.
¢ Audio-Sense On/Off Switch: When placed in the AUTO position, and when the
Master Power Switch ‚ is turned on, the SUB-TS11 will automatically turn itself on or

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-TS11 will remain on, whether or not it is receiving an audio signal.
An LED located on top of the SUB-TS11 indicates whether the SUB-TS11 is in the On or Standby state when used with the AudioSense On/Off Switch ¢ in the AUTO position. The LED is lit blue to indicate that the SUB-TS11 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-TS11 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-TS11 subwoofer’s pistonlike action moves in and out in phase with the main speakers. If the speakers were to play out of phase, the sound waves produced by the subwoofer would be canceled out, reducing bass response. This phenomenon depends in part on the relative placement 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-TS11’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 output(s) of your receiver or amplifier to these inputs. If your receiver does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver’s preamp output 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-TS11. 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-TS11, and no Y-adapter is needed.
•Speaker-Level Outputs: If you are using the Speaker-Level Inputs ª on the SUB-TS11, 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-TS11 subwoofer to the (+) terminal on the speaker, and the (–) terminal on the SUB-TS11 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.
ª Speaker-Level Inputs: If your receiver or amplifier does not have a line-level subwoofer 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-TS11 subwoofer, and the (–) terminal on the receiver/amplifier to the
(–) terminal on the SUB-TS11 subwoofer.
‚Master Power Switch: Place this switch in the “•” position to power-on the SUB-TS11 subwoofer. The SUB-TS11 will then be either in the Standby mode or completely 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 outlet for proper operation of the SUB-TS11.
The cord should not be plugged into the accessory outlets found on some audio components.

SPEAKER CONNECTIONS
Dolby® Digital or DTS® (or Other Digital Surround Mode) Connection
USE THIS INSTALLATION METHOD FOR DOLBY DIGITAL, DTS OR OTHER DIGITAL SURROUND PROCESSORS:
Use the line-level input jack marked SUB § for the low-frequency effects channel. Connect this jack to the subwoofer output or LFE output on your receiver or amplifier. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.
Make sure you’ve configured your surround sound processor for “Subwoofer On.” The front left, front right, center and surround speakers should all be set to “Small.”
When all connections have been made, plug the AC power cord on the subwoofer into an AC outlet.

Dolby Pro Logic® (Non-Digital) – Line Level
USE THIS INSTALLATION METHOD FOR DOLBY PRO LOGIC APPLICATIONS (NOT DOLBY DIGITAL, DTS OR OTHER DIGITAL PROCESSING), WHERE THE RECEIVER/ PROCESSOR IS EQUIPPED WITH A SUBWOOFER OUTPUT, OR A VOLUMECONTROLLED PREAMP (LINE-) LEVEL OUTPUT:
Use the supplied RCA-type interconnect cable to connect the line-level subwoofer output on your receiver or amplifier to either the left or right Line-Level Full-Range Input ¶ on the SUB-TS11 subwoofer. Use both the left and right inputs on the subwoofer if your receiver or processor has both left and right line-level outputs. In that case, you will need to supply a second interconnect cable.
If your receiver is equipped with line-level outputs but does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver’s preamp output 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-TS11.
IMPORTANT: Do not use the SUB Input
§ on the subwoofer with Dolby Pro Logic processors.
If your receiver/processor has a built-in low- pass-crossover filter for the subwoofer output, you may use the SUB Input § to bypass the subwoofer’s internal crossover.
Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.
Make sure that you have configured your surround sound processor for “Subwoofer On.” The front left, front right, center and surround speakers should all be set to “Small.”
When all connections have been made, plug the AC power cord on the subwoofer into an AC outlet.
