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.
