tightly focused response, set the POWER SOAK to
full power and turn the MASTER knob down. If
you want classic rock sounds replete with spongier
power tube saturation, drop the POWER SOAK
down to a lower setting and crank the MASTER
knob to give those power tubes a workout.
The POWER SOAK offers the following modes:
Normal operation - full power at 18 watts
Power reduction to 5 watts
Power reduction to 1 watt
Mute (Speaker off) = 0 watts
Note that if you choose to mute the amp, you do
not need to connect a speaker to the TubeMeister
18's SPEAKER output. Designed to enable silent
recording, this option provides the full signal to the
RED BOx output.
SPEAKER
Connect a speaker cabinet designed for guitar amps
to this jack. Using a single speaker cord, you can
connect any cabinet or combination of cabinets
whose total impedance ranges between 8 Ω and 16
Ω. The formula below serves to calculate the overall
impedance (R) of two cabinets (R1, R2).
For cabinets wired in series: R = R1 + R2
Example: If you connect two 8 Ω cabinets, the overall
impedance is 16 Ω. However, very few modern
cabinets are wired in series. Parallel circuits like that of
the TubeMeister 112 cabinet are far more common.
For cabinets wired in parallel:
R = (R1 x R2 ) / (R1 + R2)
Here's an example with to 16Ω cabs:
R = ( 16 x 16 ) / ( 16 + 16 )
R = 256 / 24
R = 8
HEADS UP: On the Combo version, this jack is
already occupied by the internal speaker. Of course,
you are free to connect another cabinet to the
SPEAKER jack if you wish. To do so, simply unplug
the built-in speaker.
MAINS IN
Connect the factory-included power cord (MAINS
LEAD) to this socket. Ensure the amp's voltage
rating matches your local AC voltage rating before
you plug the cord into the wall socket. The shaft
holding the mains fuses is located next to this
socket. When replacing blown fuses, make sure you
use specified replacement fuses only (see Technical
Specifications).
