this manual for more information. You will find controls for the power amplifier on the dedicated page of the Out-
put/Master menu:
Power Amp Switch
♦
Switches the power for the built-in power amp. There is no specific need to switch it off when not in use; unlike
a tube power amp, the built-in Class D amp is not in any danger when you have no speaker connected. Still, you
may want to switch it off to reduce energy consumption.
Power Amp Booster
♦
As mentioned, the power amp is internally connected to the MONITOR OUTPUT, which provides enough head-
room to support even the loud attacks and transients of clean guitars. However, this comfortable headroom will
naturally lower the signal volume for the power amp, so you might not achieve the desired loudness. Turning up
the "Power Amp Boost" will increase the volume loudness by up to 12 dB, in addition to the other volume con-
trols in the signal flow, such as "Monitor Volume" or "Rig Volume". The "Power Amp Boost" has no further impact
to the sound or dynamics of the power-amp. When the power amp is switched off, the "Power Amp Boost" is de-
activated, thus returning the full signal headroom to the MONITOR OUTPUT.
The internal power amp delivers 600 watts at 8 ohms; however, the wattage will be lowered to 300 watts when
used at 16 ohms. The power amplifier provides sufficient headroom to avoid clipping, even with dynamic clean
sounds. Very loud signals and transients will then be compressed by a nice, organic-sounding, soft-clipping cir-
cuit. You should, however, use these 600 watts of power with caution - if you are running at high volumes and
notice any indications of speaker distress, turn down "Monitor Volume" or "Power Amp Boost".
At 4 ohms the wattage is electronically limited to 600 watts. If these 600 watts are exceeded, the power amp
is deactivated for a short moment, which causes a short dropout. It would require insane volumes to experience
such dropouts. However, if you are connecting a 4 ohm cabinet, you should test it carefully to ensure that your
loudest signals stay below that critical level.
