Connecting to Audio Sources
Choose one of the following connection methods based on your TV or audio device's available ports:
HDMI ARC Connection (Recommended)
HDMI ARC (Audio Return Channel) allows audio to be sent from your TV to the soundbar using a single HDMI cable, and often allows your TV remote to control the soundbar's volume.

- Connect one end of an HDMI cable (not included) to the HDMI ARC port on the soundbar.
- Connect the other end of the HDMI cable to the HDMI ARC port on your TV.
- On your TV's settings, enable HDMI ARC and select the soundbar as the audio output device. Refer to your TV's manual for specific instructions.
Optical Connection
The Optical connection provides high-quality digital audio, especially useful if your TV does not have an HDMI ARC port.
- Connect one end of an optical audio cable (not included) to the OPTICAL port on the soundbar.
- Connect the other end of the optical audio cable to the optical digital audio output port on your TV or audio device.
- On your TV's audio settings, select "Optical Out" or "Digital Audio Out" as the audio output.
AUX (3.5mm) Connection
The AUX connection is suitable for devices with a standard 3.5mm audio output, such as older TVs, computers, or MP3 players.
- Connect the included AUX Cable to the AUX port on the soundbar.
- Connect the other end of the AUX cable to the 3.5mm audio output (headphone jack) on your TV or audio device.

Wall Mounting
The Memorex MX-SB270 soundbar can be wall-mounted for a clean and space-saving installation. Ensure you have the appropriate tools and fasteners for your wall type (e.g., drywall anchors, wood screws).
- Prepare the Wall: Choose a suitable location on the wall, preferably centered below your TV. Ensure there are no electrical wires or plumbing behind the drilling area.
- Mark Drilling Points: Hold the wall-mount bracket against the wall at the desired height and use a pencil to mark the drilling points through the bracket's screw holes. Ensure the bracket is level.
- Drill Holes: Drill pilot holes at the marked points. The size of the drill bit will depend on the type of wall anchors or screws you are using.
- Install Anchors (if needed): If drilling into drywall, insert appropriate wall anchors into the pilot holes.
- Secure Bracket: Align the wall-mount bracket with the drilled holes (and anchors) and secure it firmly to the wall using screws.
- Mount Soundbar: Carefully align the mounting slots on the back of the soundbar with the hooks or protrusions on the secured wall bracket. Gently lower the soundbar onto the bracket until it clicks into place or is securely seated.
- Connect Cables: Before fully securing or after mounting, connect all necessary audio and power cables to the soundbar's rear ports. Route cables neatly to maintain a clean appearance.
Note: If you are unsure about wall mounting, consult a qualified professional.
Maintenance and Care
- Cleaning: Disconnect the soundbar from the power outlet before cleaning. Use a soft, dry cloth to wipe the exterior surfaces. Do not use liquid cleaners, aerosols, or abrasive chemicals, as they may damage the finish.
- Ventilation: Ensure the ventilation openings are clear of dust and debris to prevent overheating.
- Storage: If storing the soundbar for an extended period, disconnect it from power and store it in a cool, dry place, away from direct sunlight and extreme temperatures.
