Instruction manual

J I
desired to operate the DM70 at very high sound levels, or where high
powered continuous sine wave inputs are applied, the rear absorbent
pad should be placed in position.
It will be observed that on the rear panel of the Power Unit there is
a neon indicator. This shows that the mains supply is functioning. If
the neon does not light when the mains is connected, the fuse should
be checked. A spare fuse is provided — but repeated replacements
should not be made — and if this fails you should consult your dealer.
The continental DM70 is protected on input with fuses, accessible on
the rear panel of the power supply (see figure 1 page 6). The correct
values are 1.5 amp for the fuse marked Treble, and 2 amp for the
fuse marked Bass.
