How to adjust the bass and correct the audio-video alignment of the BOSE Solo Soundbar Series II?

Accepted Answer

The BOSE Solo Soundbar Series II does not have an on-screen menu - all controls are done via the remote control. Here’s how to adjust the bass and correct the audio-video alignment:

Reduce excessive bass

Press the BASS button on the remote control
Use the + (increase) and - (decrease) buttons to adjust the level
Adjustment range: -2 (minimum) to +2 (maximum), default setting at 0
The LED indicator on the soundbar displays the selected level

Correct audio-video synchronization

If the sound is not perfectly synchronized with the video:

Access your TV's menu and disable video processing options or audio latency reduction
Look for an audio delay or audio adjustment setting to fine-tune the synchronization

Other useful features

Dialogue Mode - enhances the clarity of dialogues and voices (useful for movies and series)
TV Button - selects the TV audio

Question 2

How to connect the BOSE Solo Soundbar Series II to my television?

Accepted Answer

To connect your Bose Solo Series II soundbar to your television, three options are available depending on your TV's ports. The optical connection is the recommended method as it offers the best digital audio quality.

Method 1: Optical Connection (recommended)

Remove the protective caps from both ends of the included optical cable
Locate the Audio OUT (optical) port on the back of your television
Insert one end of the optical cable into this port on the TV and push firmly
At the other end, hold the cable with the Bose logo facing down
Align the connector with the OPTICAL port of the soundbar and insert it carefully until you feel slight resistance

Method 2: Coaxial Connection

If your TV has a digital coaxial port but no optical port, use a coaxial cable (not included)
Insert one end into the coaxial port of your TV and the other into the Coaxial port of the soundbar
This method provides audio quality equivalent to the optical connection

Alternative Methods (if your TV has no optical or coaxial port)

TV Headphone Port: Use a 3.5 mm stereo cable (not included) plugged into the headphone port of your TV to the AUX input of the soundbar
Analog RCA Ports: Connect a stereo RCA cable (3.5 mm to RCA, not included) to the red and white RCA Audio OUT ports of your source to the AUX ports of the soundbar

Important Final Steps

Once the cable is connected, turn on your TV and test the audio through the soundbar
Disable your television's speakers in the audio menu to avoid distortion: access your TV's audio settings (refer to your television manual for the exact procedure)
The included remote control automatically operates the soundbar once connected. The TV button allows you to switch between the TV and Bluetooth devices
Never unplug the HDMI video cable from your TV, only the audio cable should be connected to the soundbar

Question 3

Why is the remote control for my BOSE Solo Soundbar Series II not working?

Accepted Answer

The remote control uses infrared and must be factory paired. If it is not responding, first check these points:

CR2032 Battery: Open the back compartment by turning the cover counterclockwise. Ensure the CR2032 battery is properly inserted with the “+” symbol facing up. If it appears old (more than 6-12 months of use), replace it.
Direct Line of Sight: Point the remote control directly at the front of the soundbar, within 3 meters. Obstacles may block the infrared signal.
Reset: Unplug the soundbar from its power source for at least one minute, then plug it back in. Wait for the soundbar's LEDs to stabilize.

After these checks, test the power button (⏻) to see if the remote control responds. If the problem persists after replacing the battery, it may indicate a hardware defect in the remote control.
