Marshall Acton IV Bluetooth Speaker - Black

No, the Acton IV is designed to be a stationary speaker and must be plugged into an AC outlet at all times.

Yes, through Auracast support, you can link multiple compatible speakers for synchronized playback.

The M-button is a customisable control that you can program via the app to trigger specific EQ presets or open Spotify playlists instantly.

The Acton IV is not rated for water resistance; keep it in a dry indoor environment.

You can connect it via the analogue input if your TV has an audio output, though it is primarily optimized for music listening.

Firmware updates are managed exclusively through the Marshall Bluetooth app when the speaker is connected to Wi-Fi/Bluetooth.

Ensure Bluetooth is enabled on your device, restart the Marshall app, and confirm the speaker is in pairing mode.

Check the EQ settings in the Marshall app; you may need to reduce the bass levels if the current room placement is causing excessive resonance.

Ensure your turntable has a built-in phono preamp; if it does not, you will need to add an external phono preamp between the turntable and the speaker.
