24. OUTPUT
This three posion rocker switch
combines STB (standby) and HIGH/LOW
output power funcons. The output stage
and power control for this amplier has
been designed to deliver the opmum
tonal performance at all power levels.
The high and low output funcons
allow the user to choose between two
conguraons of the internal power
supply. These two conguraons give the
choice between two output power levels,
but ensure that the output valves behave
in the same way for both. This means the
amplier can be put into low power mode
without compromising on tone.
HIGH: This is the 100 Wa seng for
the DSL100HR and the 40 Wa seng
for the DSL40CR.
STB (standby): This is used in conjuncon
with the mains power switch (front panel
funcon #25). When powering up, always
switch mains power on rst, leaving
the output switch in the STB (standby)
posion. Standby mode should also be
used to mute the amp during breaks
in performances to avoid stress to the
valves of the amplier.
LOW: This is the 50 Wa seng for
the DSL100HR and the 20 Wa for the
DSL40CR.
25. POWER
Mains power on/o switch.
