CAUTION!
Hot! Risk of injury! During use, the valves get
very hot and high surface temperatures may
be reached at the rear of this unit. Avoid
touching the controls and connectors on the
rear panel during use. To avoid accidental
contact with hot surfaces, place the rear panel
so that it faces a wall.
23 The calibrated LEVEL control determines the signal
level sent to an external effects unit or any other
signal processor (0 – 10). Turn the control to the
right to increase the amount of signal information,
and turn it to the left to decrease the amount. It
makes sense to select a high setting in order to get a
possibly noise-free signal. The FX Send LEVEL and
FX Return LEVEL (26) controls should always be set
oppositely. For example, to reach a 0 dB working
level when the FX Send LEVEL is set low, the
FX Return LEVEL (26) needs to be set high
accordingly. On the other hand, if you wish to boost
the volume level, turn both controls to a higher
setting.
24 The SEND output is used to connect a shielded
¼" mono jack cable to the input of an external effects
unit.
25 The RETURN input is used to connect a shielded
¼" mono jack cable to the output of an external
effects unit.

26 The calibrated LEVEL control determines the signal
level returned from an external effects unit or any
other signal processor (0 – 10). Turn the control to
the right to increase the amount of signal information,
and turn it to the left to decrease the amount. To
achieve a possibly noise-free signal, set the FX Send
LEVEL (23) relatively high and the FX Return LEVEL
relatively low. A BOOST effect can be achieved with
this LEVEL control when the RETURN input isn't being
used. Increase the volume level with this control plus
activate the FX LOOP with the footswitch in order to
make the guitar signal louder. This function is great
for highlighting solos.
27 The 7-pin FOOTSW(itch) connector is provided to
connect to the supplied BUGERA FSB104 footswitch.
Please be sure to connect the cables before switching
on the amplifier. Refer to „Footswitch" for details.
28 The DAMPING switch lets you specify the damping
factor of the BUGERA (only 333 and 333-212). The
term „damping" refers to a feature of the amplifier
that affects the signal's fade-out phase. A high
damping factor (HIGH) makes the signal fade out
quicker than a low factor (LOW). Changes to the
damping factor automatically result in level alterations
which should be re-adjusted.

29 The IMPEDANCE switch lets you specify the
loudspeaker impedance. Always apply the value that
is identical to the impedance of the used speaker
cabinet. When connecting two cabinets with the same
impedance, the switch should be set to half the value
of one of the cabinets. For example, two 16-Ohm
cabinets would require an 8-Ohm setting, while two
8-Ohm cabinets need to be set to the minimum
impedance of 4 Ohms. Please also read „Wiring the
BUGERA".
30 Both the paralleled LOUDSPEAKER outputs
(¼" mono jacks) are used to connect the speaker
cabinet(s). The minimum impedance is 4 Ohms. The
IMPEDANCE switch should always be set to match
the impedance of the used speaker cabinet.
31 This is the LEVEL control that specifies the signal
level for the OUT (32) in order to adjust the level of
a second amplifier and loudspeaker system connected
over the OUT to the LOUDSPEAKER outputs (30) of
one or more connected speaker cabinets.
32 The OUT provides a preamp signal in order to feed
the signal to a second amplifier and loudspeaker
system, for example.
33 The FUSE is found in the fuse holder. If the fuse is
blown, it needs to be replaced with a fuse of the
same kind by all means. Otherwise, the unit could
seriously be damaged, in which case the warranty is
void. If the fuse is blown repeatedly, you should take
the unit to a qualified service technician.
WARNING: ONLY REPLACE THE FUSE WHEN THE
MAINS CABLE HAS BEEN DISCONNECTED!
34 The IEC MAINS connector is used to connect the
mains cable that has the appropriate voltage ratings
for your country (included). At all times, make the
connections to the amplifier before plugging the cable
into a power outlet.
35 This is the SERIAL NUMBER of the amplifier.
