3.4.- CONNECTION TO MAINS
The mains lead has three isolated copper cables for connection to
mains. Colour codes are brown (live), blue (neutral) and yellow-
green (earth). Nominal AC voltage is 230V. Export versions may
operate at 115 V AC. Nominal AC voltage will always be indicated
on the back panel.
For electrical safety, a fuse is housed inside the amplifier mounted
on a fuse holder. Figure 3.5 shows the location for models E-8, E-12
and E-20. For models E-2 and E-4, it can be easily found in front of
the input circuit board. If blown, replace it by
one of exactly the same type. (Fuse type for
each model is indicated on the fuse itself as well
as around the fuse holder).
On models E-8, E-12 and E-20, the nominal AC
voltage can be changed easily from 115V to
230V. First, unplug the amplifier from the mains
and open the top cover. On the AC board (see
Figure 3.5), in proximity to the capacitors and
the output relays, there is a 12-pin connector plugged into its
corresponding 12-pin socket. Plug the connector into the empty
socket next to it to change the nominal AC voltage, which is
indicated on the circuit board, next to the socket. After doing this,

you must replace the fuse for the appropriate one for the AC
voltage chosen, which can be found on the table below. Model
E-20 utilizes the same fuse for both voltages, so fuse replacement
is not needed.

3.5.- POWER CONSUMPTION

Can be seen on the accompanying table for 230V. Double the ratings
to get the 115V current consumption.

International safety agencies specify AC consumption using pink
noise at 1/8th of maximum power. This is done to represent the
current requirements to reproduce a typical musical programme.
The 1/3rd power rating represents a worst case scenario, while the
maximum power represents consumption with sine wave signal,
which will never occur in practice.
