Voltage selection

The Nº27.5 is factory-set (internally) for 100V, 120V, 200V, 220V, or
240VAC mains operation. Check that the label on the rear panel of
the amplifier indicates the correct AC operating voltage for your
location.

If the voltage indicated is incorrect, see your Mark Levinson dealer.
If you wish to change the AC operating voltage of your Nº27.5, see
your Mark Levinson dealer.
A Nº27.5 may be powered by a 15-ampere AC mains line. Lack of
available current from the AC circuit may affect the amplifier's
performance, so if other devices are also powered from the same AC
circuit, you must consider their additional power consumption. For the
best results, we recommend that you connect the Nº27.5 to an
isolated, dedicated AC circuit with a minimum rating of 15 amperes.
Two slow-blow 250V 3AG fuses (10 ampere @ 100V and 120VAC, and
6.25 ampere @ 200V, 220V, and 240VAC) are located on the rear
panel of the Nº27.5. Replace the fuses with the same type only.
ALWAYS remove the AC cord before removing the fuses.
