Behringer Thunderbird BX108 - Manual (Page 6)

6 THUNDERBIRD BX108 User Manual
1. Introduction
With the THUNDERBIRD you purchased a retro-style bass amp
that offers you lots of practical uses in a really cool design.
When developing the BX108, our top-priority goal was to fully
exploit its sound potential and combine it with a set of useful
connection options.
With the THUNDERBIRD BX108 we purposefully went back to the
roots of bass amplification. We realized the idea “less is more” by
designing a “nostalgic” practice amp that allows you to fully unfold
your creativity. With its well-balanced basic sound it gives you what is
most important when playing: lots of fun!
1.1 Before you begin
Your BX108 was carefully packed in the factory and the packaging
is designed to protect the unit from rough handling. Nevertheless,
we recommend that you carefully examine the packaging and its
contents for any signs of physical damage, which may have occurred
during transit.
◊ If the unit is damaged, please do not return it to BEHRINGER,
but notify your dealer and the shipping company
immediately, otherwise claims for damage or replacement
may not be granted. Shipping claims must be made
by the consignee.
Please ensure that your BX108 is set to the correct supply
voltage before you connect the unit to the AC power system!
Three triangular markings can be found on the fuse holder at the AC
power connection socket. Two of these three triangles will be aligned
with one another. The BX108 is set to the operating voltage shown
next to these markings and can be switched over by twisting the
fuse holder by 180°. IMPORTANT: This does not apply to export
models designed only for 115 V ~!
Please ensure sufficient air circulation around the unit and do not
place the BX108 close to a radiator or other heating system, so as to
avoid overheating.
◊ Please note that all units must have a proper ground
connection. For your own safety, never remove or disable
the ground conductor of the unit or of the AC power cable.
