Standard Setup/ Cable Connections - Hughes & Kettner TubeMeister Deluxe 40 Mode D'emploi

TubeMeister 40 Deluxe – Manual 1.3b
Speaker
Connect a speaker cabinet designed for guitar amps
to this jack. Using a single speaker cord, you can
SPEAKER
connect any cabinet or combination of cabinets
8 - 16 Ohms
whose total impedance ranges between 8 ohms and
16 ohms. The formula below serves to calculate the
overall impedance (R) of two cabinets with different
impedances (R1 and 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.
The shaft holding the mains fuses is located next to this socket. Replacing
blown fuses is a job to be carried out by fully qualified technicians
only using exclusively the specified replacement fuses (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 40, 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.
