Hughes & Kettner TubeMeister Deluxe 20 Mode D'emploi page 5

You can use the Red Box Out and Speaker Out simultaneously. The Red
Box doesn't just work in silent mode – it works in any of the Power Soak's
modes too. If you want to use the Red Box Out and Speaker Out together
in a live situation, please make sure that all your channels and presets use
the same Power Soak setting to avoid unwanted changes in the Red Box
Out's level!
Controls
Vintage/Modern The "Modern" voicing gives you the bark and
honk of modern speakers, while "Vintage" yields
a warmer, woollier tone associated with old-
school cabs.
Small/Large "Small" captures the compressed sound of a small
cabinet housing; "Large" gives you the greater
girth and added bass of a sizable cabinet.
Line/Mic Switches from line level to microphone level.
Off/On Switches off the cabinet emulation. Make sure
this switch is set to "On" unless you want to use
external cabinet emulators!
Note: Why and when would you want switch off the Red Box AE's
incredibly authentic cabinet emulation? Well, in a recording situation,
you or the engineer may want to capture the pure speaker signal to use a
software-based cabinet and microphone emulation or impulse responses
of cabinets and rooms/ambiences. This allows you to experiment with a
variety of cabinet and ambience combinations and even lets you change
the microphone after the track is already recorded!
Tip: If you think the Red Box output sounds a little bit strange, please
check if the cabinet emulation is switched on. If it is switched off while
you want to use it direct to the mixing desk in a live situation, it will result
in an unfiltered tone that could be described as "nasty"
Power Soak
Use this knob to adjust the TubeMeister Deluxe 20's output power and
set its basic volume level. This feature lets you enjoy the benefits of full-
blown power amp saturation at low volume so you can play at home
in your living room without alienating the neighbors. The amp's silent
recording capability lets you capture genuine tube-driven tone via a
mixing console without having to drive speakers. Plus, if you want to
rehearse in silence at any time of the day or night, simply plug a set of
headphones into the mixer.
The Power Soak is not just about managing volume; it's also about
conjuring the right tone and response. For modern sounds that demand
a fast, 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 20 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 Deluxe 20's Speaker output. Designed to
enable silent recording, this option provides the full signal to the Red Box
AE 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 ohms and 16 ohms.
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 ohm cabinets, the overall impedance is
16 ohms. However, very few modern cabinets are wired in series.
Parallel circuits are far more common, because in a serial wiring, the
signal has to be interrupted to integrate an additional cab into the wiring.
This also means that when you remove the additional cab, the circuit is
indeed interrupted. You always need automatic switching solutions or
manual switching to close the interrupted circuit. With parallel wiring,
there is no interruption needed.
• For cabinets wired in parallel: R = (R1 x R2) / (R1 + R2)
Here is an example with two 16-ohm cabs:
R = (16 x 16) / (16 + 16)
R = 256 / 32 = 8 ohms
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).
AES (EU version only)
Referred to Commission Regulation (EC) No. 1275/2008, electrical and
electronic devices need to be equipped with an energy-saving mechanism
which automatically switches the device off after not being used for a
certain period of time. On your TubeMeister Deluxe 20, this mechanism
is called AES. AES can be activated and deactivated with the mini switch
right next to the speaker jack. The factory default is AES on; the mini
switch is in the left position. In this mode, the amp will automatically
be switched off after a phase of silence of about 90 minutes. The phase
of silence is reset and starts again as soon as the amp receives an input
signal (e.g. by you playing a note). A quite gentle signal is enough to
trigger the restart of the 90-minute phase of silence until the amp will
switch off automatically again. After automatically being shut down by
AES, the amp can be switched back on by flipping the Power/On and
Play/Standby switch off and then on again.
