If the effect does not appear on the control pod, see the troubleshooting section of this guide.

11.If using stereo content: The effect button allows you to select between Stereo (front left/right speakers only) and Dolby® Pro Logic® II Music or Movie Mode to create 5.1 audio from a 2-channel stereo source.

12.Once the input and effect are correctly displayed on the control pod, you are ready to enjoy your new speakers.

Pairing the Wireless Rear Speakers

The wireless rear speakers are automatically paired with the system at the factory. When you first setup the system, the system will automatically locate the rear speakers. A successful connection is indicated by solid LEDs on both the Digital SoundTouch™ Control Center and the wireless rear speakers.

Troubleshooting the Wireless Rear Speakers

If the wireless rear speakers lose their connection to the system, first use the Wireless LEDs to diagnose the problem (see below). To re-establish a link, first locate the pinhole for the connect button on the bottom of the Control Center. Using a paperclip, push the connect button through the pinhole. The system will start looking for the wireless rear speakers, as indicated by the flashing Link LEDs on the back of the Control Center. The system will continue looking for the rear speakers for 2 minutes.

	Effects
	The effect button is used to select the type of surround sound or audio technology you want to use with a
	particular input. In many cases, the control pod will recognize what audio technology is streaming from your
	audio device, and will automatically select it.
	For example, if you are watching a DVD and have selected the Dolby® Digital 5.1 stream on the DVD, then
	when you select the DVD audio input, Dolby® Digital will automatically be the selected effect. The control
	pod will default to the last effect used by whatever input source you are using.
	You can use the ‘effect’ button to select a different audio technology if you wish to change it. Note that not
	all effects are available for all inputs (refer to the table):
	Repeatedly pressing the ‘effect’ button rotates through the available options for that type of input. If only one
	effect option is available, then the effect button will have no impact.
	Whenever the input or bitstream changes, the previously selected effect will be automatically re-selected. For
	example, if you select Dolby® Pro Logic® II while listening to the 6 ch. Direct input, ‘Dolby® Pro Logic® II’ will
	be stored in memory for the ‘Direct’ Input. The next time you select the Direct input, Dolby® Pro Logic® II will
	be automatically selected as the effect.
	When returning from Standby, the previously selected input and effect will be shown on the control pod.
	Each effect is described on the next page. For more information about surround sound and other digital
Operation	audio technologies, visit www.logitech.com.

pink noise ‘test tone’ will be played from each speaker instead of the selected source input. This tone will
come from one speaker at a time, in 2.5 second intervals, in the following order: left front, center, right front,
right rear, left rear, sub. To exit this state, just press the ‘Test’ button again.
Use the Test state to verify that your speakers are connected properly, or to set levels between the rear, front,
and center channels.

Frequently Asked Questions

Q.Can I extend the speaker cables?

A.Yes. Purchase standard speaker wire, 20AWG and cut and strip to desired length. Using any other gauge wire is not recommended, may damage the system and may void your warranty.

Q.There is no sound coming from one (or more) speakers.

A.Confirm that the speaker is connected properly. When inserting the wire, make sure the bare wire sits on the metal connector in the spring clip. This is critical – metal must be on metal – or the connection will not be sufficient. Sometimes the plastic wire shielding is pushed onto the metal connector, which prevents the wire from making a solid contact with the connector in the spring clip. This will also prevent your speaker from working. If this is the case, simply pull the wire out some so that the wire makes a clean contact with the metal part of the connector.

Q.What happens if the speaker wires are reversed? (red wire to black spring clip on one speaker, red wire to red spring clip on the subwoofer, or vise versa)
