audio
All Blueshift speakers include a 3.5mm stereo audio input. Mono speakers mix that input
down, so both channels are represented even on the Mono speakers.
The mono input is always on, even if Bluetooth is on.
All controls for playback (volume, track, etc.) are the controls on your phone or other device.
There are no such controls on Blueshift products.
It may be possible to turn your device up loud enough that it starts to distort.
This can
damage the driver(s) and/or the amplifier(s).
If it starts to sound crunchy and bad, turn it
down! Blueshift is not responsible for blown drivers.
The hole in one end of your speaker is a tuning port ('bass port'). It tunes the enclosure to
105-110 Hz, increasing the loudness around that frequency. On Mono speakers, there is a
tube to increase the length of this port. On Stereo speakers, the thickness of the bamboo is
the correct length for the port and there is no tube.
Inside the cabinet, there is white acoustical damping material (stuffing). This is a part of your
speaker system and should not be removed.
The grills that cover the drivers may be removed:
1. Use a Phillips screwdriver to remove the four mounting screws.
2. Remove grill and spacers
3. Re-install mounting screws BY HAND just until the driver is held flush to the cabinet,
being careful not to overtighten. If you do strip a screw hole, you can fill it with wood
glue to regain some holding power.
Your speaker uses one or more Fostex FE126En 4” full-range drivers. These are replaceable
in the event of damage.
