Most Technomad loudspeakers are equipped with protective fuses. Our fuse assemblies help to protect the internal passive net-works from catastrophic failure of the amplifier, and from severe over-driving of the loudspeaker. These fuses will not protect the driver from damage due to clipping or excessive power. The fuses are not a guarantee against damage to the network- the user is still liable for any damage due to overpowering or improper use of the loudspeaker.
Fuse(s) are installed within fuse holder(s) located at the bottom or back of the loudspeaker. Fuse can be accessed by lightly pushing and turning the slotted center of the fuse holder counter-clockwise (open) using a standard blade screwdriver.

ALL FUSES ARE 1-1/4″ x 1/4″ 250v ceramic slow-blow fuses – only the amp-value varies. Some loudspeakers have two fuses. 70-volt (“T”) Models, i.e. the Vienna 16T do not have fuses.
