Short answer
Adjust the volume, bass, and treble by turning the three control knobs on top of the speaker or by using the Marshall Bluetooth app.
Volume Control
Adjust the loudness with the volume knob. Set it to five (right in the middle) for an optimal volume-to-playtime ratio.
Bass Control
Use the bass knob to adjust the low-frequency audio output. The default position is five (right in the middle), also known as flat or unaffected EQ.
Treble Control
Use the treble knob to adjust the speaker for clarity and shrill high frequencies. The default position is five (right in the middle), also known as flat or unaffected EQ.
