How to adjust the Volume, Bass or Treble
Adjust the volume, bass, and treble on Stockwell II by using the three control knobs.
Volume Control
Adjust the loudness with the volume knob. The volume greatly affects the playtime of the battery. Set it to five (right in the middle) for an optimal volume-to-playtime ratio. The volume knob also turns the Stockwell II on and off.
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.
How adjustments affect battery time
The knobs do not use simple addition and subtraction when increasing or decreasing the levels. This means that battery levels may be significantly affected when cranking the knobs.
