Frequently Asked Questions - MS115 Acoustic Solutions

How do I pair my phone with the MS115 speaker via Bluetooth?

Press and hold the Bluetooth pairing button on the speaker until the LED flashes blue. Enable Bluetooth on your phone and select 'Acoustic Solutions MS115' from the device list. The LED will turn solid blue when connected.

Can I use the speaker while it is charging?

Yes, the MS115 supports pass-through charging. You can play audio while the AC adapter is connected. However, if the battery (if present) is low, performance may be affected.

What is the maximum volume level?

The volume knob allows you to adjust output up to 20W RMS. Turning it to maximum may cause distortion; we recommend keeping volume at 80% for best audio quality.

How do I clean the speaker cabinet?

Unplug the speaker and use a soft, dry cloth to wipe the exterior. Do not use water, solvents, or abrasive cleaners. For the grille, use a soft brush or vacuum with a brush attachment.

What should I do if there is no sound output?

Check that the speaker is powered on (blue LED). Ensure the audio source is playing and the volume is turned up. If using Bluetooth, verify pairing. Try a wired connection via AUX to isolate the issue.

Can I connect two MS115 speakers for stereo sound?

The MS115 does not support daisy-chaining or wireless stereo pairing. Each speaker operates independently. For stereo, you may use a splitter cable with a separate amplifier.

What is the Bluetooth range of the MS115?

The effective Bluetooth range is approximately 33 feet (10 meters) in open space. Walls and obstacles may reduce the range.

Does the speaker have a built-in microphone for hands-free calls?

No, the MS115 is designed for audio playback only and does not include a microphone. For calls, use your phone's speaker or a headset.

How do I reset the speaker to factory settings?

To reset, turn off the speaker, then press and hold the Bluetooth button while turning it back on. Continue holding until the LED flashes red/blue. Release; the speaker will restart in pairing mode.

What is the power consumption in standby mode?

In standby mode (red LED), the speaker consumes less than 0.5W. For full energy savings, unplug the AC adapter when not in use for extended periods.
