Speaker placement

Before you position your speakers, take a look around your room and figure out the best setup (see diagram to the right). It’s easiest to place all your speakers in the desired locations before attaching any cables.

Satellite speakers – Place the two front satellite speakers on either side of your computer monitor or television, about the same distance from each other as they are from your listening position (e.g., the couch). Angle them to face you. Place the two rear speakers behind you and about the same distance apart as the front speakers. You may want to mount these speakers on the wall (see Wall mounting).

Center satellite speaker – Place your center satellite speaker on your desk or in front of your monitor or television; you may also wall-mount it.

Subwoofer – You can place the subwoofer anywhere in relation to the other speakers. To get the strongest bass, place your subwoofer near a wall or corner, or under a desk. Make sure that nothing is closer than 16 cm to the driver or the bass port because it will affect your sound. It’s also important to have adequate ventilation around the subwoofer.

Control console – Place the control console where it’s easy to reach, and make sure the IR window is in plain view so the remote control can communicate with it.

Connecting your speaker cables

The Z906 comes with five speaker cables: two 7.6-meter cables for the rear satellites and three 4.6-meter cables for the front and center satellites. When connecting your speakers, the control console, and your audio source, make sure the power to the system is off.

Connect the speaker cables – Connect your satellites to the subwoofer using the speaker cables. Push the tab on the spring clip, insert the wire into the connector, and release the tab. Be sure that you match the wire color (red or black) to the spring clip colors on both the subwoofer and the satellite.

Connect the control console DB-15 cable – Connect the control console DB-15 cable to the corresponding DB-15 pin connector jack on the subwoofer.

Connect the subwoofer power cable.

Plug the subwoofer power cable into an electrical outlet.

Adjust volume

Set volume to the nine o’clock position to test; adjust thereafter as needed.

Turning on your system

Press the POWER ON/OFF button on the remote control or control console to turn on your Z906.

Testing your system

To test whether you have correctly set up your speakers, press and hold the INPUT button on the remote control or control console for 5 seconds to put your system into test mode. In test mode, the system cycles through each speaker, playing an audible test signal. The test signal comes from only one speaker at a time, in 5-second intervals, in the following order: left front, center, right front, right rear, left rear, and subwoofer.

As a channel is tested, its corresponding LED lights up on the front panel of the control console. The test signal cycles through each speaker once and stops. To re-enter test mode, press and hold the INPUT button on the remote or control console for 5 seconds.

Connect the audio source cable.

Turn off speakers.

Connect your audio source (e.g., TV, DVD, computer) to the appropriate input jack on your subwoofer.

• For computer sound cards, use the 6-channel input ① (cable included).
• For stereo devices, use the Stereo RCA input ② (cable not included).
• For digital devices, use the digital inputs 3 4 5 (cable not included).

Selecting your audio input

Use the remote control or the control console to select an input source. Pressing the INPUT button cycles through the various audio input sources, which will always cycle in the same order.

Digital input

If you’re using a digital connection, follow the instructions on your audio source to make sure you’re getting digital audio output. For digital content, the control console automatically detects and displays the digital stream as long as the device is connected to a digital input. For example, if you have selected the DTS Digital Sound or Dolby Digital 5.1 stream for a DVD you want to watch, it will be detected automatically when you choose the applicable input.

Using the Effect select control with stereo sources

When playing stereo audio, you can use the Effect Select control on the remote control or the control console to choose the type of sound you want to hear.

• Stereo 3D – Provides a 3D surround sound effect through all speakers
• Stereo 4.1 – Plays stereo through both front and rear satellites, plus the subwoofer
• Stereo 2.1 – Plays stereo through both the front satellites and the subwoofer
• No Effect – Plays audio format of your computer’s sound card without applying any effects. Available for 6-channel input only and is represented by having no Effect LEDs illuminated.

Whenever you change the input, the last effect you selected is automatically restored. For example, if you select Stereo 3D while listening to Input 2, the next time you select Input 2, Stereo 3D is automatically selected.

Enjoy!

After you’ve made sure that you’ve set up your system correctly—and the selected input and effect are correctly displayed on the control console—you’re ready to go. Just press play and get immersed in your new Z906 speaker system.

Frequently asked questions

Q: I can’t hear any sound out of my Z906 speakers, and I see flashing lights on the front of the control console. How can I resolve this?

A: a) The Z906 uses DTS Digital Sound/Dolby Digital decoding to process data into 5.1 surround sound. If the Z906 receives neither DTS Digital Sound nor Dolby Digital decoding data, the Z906 will not be able to decode the signal. You can resolve this issue by making sure the Z906 receives only a DTS Digital Sound or Dolby Digital signal from the host device (for example, DVD/Blu-ray player, game console, or home computer). Please refer to your equipment manufacturer’s support documentation for additional details.

A: b) Most DVD and Blu-ray Disc movies have audio encoded in both DTS Digital Sound and Dolby Digital. Check the on-disc Audio menus to make sure the movie is playing either a DTS Digital Sound or Dolby Digital signal.

Q: Where can I learn more about my speakers?

A: Visit the Logitech website at www.logitech.com. If none of the above answers resolve the problem, please contact Logitech Customer Support.

Error states

• No data – If you select a digital input and no digital stream exists for that input, the Effect and Decode indicators on the control console will not be illuminated.
• Unknown data – The Decode and Effect LEDs will cycle continuously when you select a digital input, and its data stream cannot be decoded because the digital content is neither DTS Digital Sound nor Dolby Digital.

Wall mounting

You can mount your satellite speakers with the appropriate hardware (not included). When attaching a satellite speaker to a wall mount, make sure not to overtighten the mounting screw. Doing so may damage the screw threads inside the speaker’s mounting lug.
