Mains Supply Connections
Mains Voltage Setting
Type 2719 can be powered from a 100 V, 120 V or 230 V
±
10% (50 to 60 Hz), single-phase AC
mains supply. To select the correct mains voltage setting, use a small screwdriver to remove the
voltage selector with integrated fuse holder from the combined voltage selector and mains
power inlet, then put it back again so that the white dot on the amplifier unit is aligned with the
appropriate voltage printed on the selector.
Fuse Check and Replacement
The mains fuse and fuse holder are integrated in the voltage selector. It can be released using a
screwdriver. For 100 V and 120 V operation, the fuse should be a T6.3 A slow blow, whilst for
230 V operation it should be a T3.15 A slow blow. Make sure that only fuses of the required
rated current and of the specified type are used for replacement. Do not use mended fuses or
short-circuit the fuse holder.
Mains Socket Connection
Once the mains voltage setting and fuse are correct, use the power cable provided to connect
the mains to the mains input socket of the amplifier. Note that for maximum operating safety
