Faqs

How do I set up the Marshall Stanmore II Speaker for the first time?

To set up your Marshall Stanmore II Speaker, place it on a stable flat surface with adequate ventilation. Connect the provided AC power cable to the speaker's rear power input, then plug into a wall outlet (100-240V). Turn on the speaker using the top power lever. Use the source button on top to select Bluetooth, AUX, or RCA as your input. For Bluetooth, hold the source button for 2 seconds to enter pairing mode and connect your device[1][2][7].

What should I do if my Marshall Stanmore II Speaker is not pairing with Bluetooth devices?

If the Marshall Stanmore II Speaker doesn’t pair, first ensure it's in Bluetooth input mode by pressing the source button until the Bluetooth LED lights up. Then press and hold the source button for 2 seconds to enter pairing mode—the Bluetooth indicator will blink. On your device, search for 'Marshall Stanmore II' in Bluetooth settings and connect. If issues persist, restart both devices and try again[5][7].

Can the Marshall Stanmore II Speaker be connected to a turntable or record player?

Yes, the Marshall Stanmore II Speaker can connect to a turntable via its RCA input on the back. However, the turntable must have a built-in RIAA preamplifier or you need to use an external preamplifier to boost the signal. After connecting the RCA cables, select the RCA input by toggling the source button on the speaker until RCA is active[3][4].

How do I adjust the sound settings like bass and treble on the Marshall Stanmore II Speaker?

The Marshall Stanmore II features three rotary knobs on top to adjust volume, bass, and treble. Turn the bass knob to increase or decrease low frequencies, treble knob for high frequencies, and volume knob for overall loudness. These settings can also be adjusted remotely using the Marshall Bluetooth app on your smartphone for more precise control[3][4].

Is it possible to pair two Marshall Stanmore II Speakers for stereo sound?

Yes, you can couple two Marshall Stanmore II Speakers using the Marshall Bluetooth app. Connect both speakers to the app, then use the 'Couple Speakers' feature to pair them. You can choose between ambient mode, where both speakers play synchronized audio, or stereo mode, where one speaker outputs the left channel and the other the right, creating a true stereo effect[6].

What should I do if my Marshall Stanmore II Speaker produces crackling or distorted sound?

Crackling or distortion can result from interference or connection issues. Ensure your Bluetooth device is within range (1-2 meters), and try disconnecting and reconnecting Bluetooth. Check all wired connections (AUX or RCA) for secure fitting. Adjust bass and treble knobs as extreme settings can cause distortion. If the problem continues, perform a factory reset or update firmware via the Marshall app[2].

How can I maintain and clean my Marshall Stanmore II Speaker to ensure lasting performance?

To maintain your Marshall Stanmore II Speaker, keep it in a dry, dust-free environment. Clean the exterior gently with a soft, dry cloth; avoid harsh chemicals or water contact. Ensure ventilation ports on the back remain unobstructed for proper airflow. Regularly update the speaker firmware via the Marshall Bluetooth app to optimize performance[1][4].

What input options does the Marshall Stanmore II Speaker support and which devices are compatible?

The Marshall Stanmore II supports Bluetooth 5.0 with Qualcomm aptX for high-quality wireless streaming, plus wired inputs including 3.5mm AUX and RCA. It is compatible with smartphones, tablets, computers, and audio sources like turntables (with preamp). The source button toggles between inputs, enabling versatile connectivity for most modern audio devices[1][2][4].
