Safety
*For wireless transmission to the rear channels, Logitech introduces the world’s first THX™-certified wireless rear speaker 
system that features independent rear channels (no wires between rear speakers or a receiver box). This proprietary 
digital wireless technology offers state of the art clarity and reliability with adaptive channel hopping, redundant 
transmission of music streams, and low latency using 48kHz sample rates. 96kHz audio streams are re-sampled to 
48kHz in the rear channels only.

Initial Setup Overview:1.  Front Satellite Speakers
Before attaching the cables, position the two front satellite 
speakers on either side of your computer monitor or television 
about the same distance from each other as from you. Angle 
them to face you. Place the two rear speakers behind you 
and about the same distance apart as the front speakers. 
Your Logitech® Z-5450 speaker satellites are wall mountable. 
Unscrew the satellite stand from the satellite speaker base, 
exposing the stability pins on the base. Rotate the speaker stand 
180 degrees and reattach the stand to the base, ensuring the 
stability pins line up with the openings provided. Do not over 
tighten the screw. Mount the speakers using appropriate wall 
anchors through the holes in the stands.
  For a pro-audio look, remove the cloth grilles by pulling them straight 
off. Removing the grilles will not affect sound quality.
2. Center Channel Speaker
Depending on your configuration, place your center channel speaker 
on your desk (angled up), on top of your monitor or television (angled 
down), or wall-mounted (angled down). Your Logitech® Z-5450 speaker satellites are wall mountable. 
Unscrew the satellite stand from the satellite speaker base, exposing the stability pins on the base. 
Rotate the speaker stand 180 degrees and reattach the stand to the base, ensuring the stability 
pins line up with the openings provided. Do not over tighten the screw. Mount the speakers using 
appropriate wall anchors through the holes in the stands.
3. Subwoofer
Because bass frequencies are non-directional, the subwoofer can be placed anywhere in relation to the 
other speakers. To ensure optimum sound quality, do not block the driver or the bass port. To achieve 
the strongest bass, place the subwoofer near a wall, corner or under a desk.
  Note: Please ensure adequate ventilation around the subwoofer. Keep the cooling fins on the back of 
the subwoofer at least 6 inches away from any object.
4. Digital SoundTouch™ Control Center
Position the Digital SoundTouch™ Control Center where it is easy to reach.
5.  With the power off and the speakers in place, connect the speaker wire to the spring clips on the 
front and center satellite speakers and to the corresponding spring clips on the subwoofer. For each 
speaker wire, make sure to match the red and black spring clip terminals on the subwoofer with the 
corresponding terminals on the speakers. To connect, push the tab on the spring clip, insert the wire 
into the connector, and release the tab. Make sure that you match the wire color to the spring clip 
colors on both the subwoofer and the satellite. To setup your system, see the Quick Start guide.

EffectsThe 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 
audio technologies, visit www.logitech.com.

Unknown Digital Data: Appears when a digital input is selected and it is a stream that cannot be decoded 
by the Z-5450 Digital. Test StateThe ‘Test’ state is only accessible by pressing the ‘Test’ button on the remote control. When in this state, a 
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 QuestionsQ.   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.   Confi rm 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 suffi cient. 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)
