Hughes & Kettner Tube 50 - Handbuch (Seite 12)

MSM-1 socket and indicator notch.
Insert the MSM-1 in the module chamber and
fasten it to the chassis using the four screws
that you removed from the cover plate. Ensure
the electronic components and the module
inscriptions on the rear panel are facing right-
side up.
Position of the sockets.
• Plug the other ribbon-cable connector into the socket on the cir-
cuit board. Note the markings on the connector and ensure they
face the grooved portion of the jack when you plug the connec-
tors in.
• Ensure the connector fits snugly and the connector markings
match the jack's grooved portion.
• Replace and fasten the chassis cover and insert all cable
connections.
• Once you have switched the amp on, all MIDI functions should
be accessible immediately. Check out all the switching functions
of your amp.
NOTE: If you have connected the MSM-1 Module's polarity in
reverse, then the amp's secondary fuse may trip. Replace the
fuse if this happens. Generally, this should not damage the MSM-
1.
Please consult the MSM-1 Operator's Manual for detailed instruc-
tions on MIDI programming and switching.

TUBE 50/100 - MANUAL
TIP:
If you choose not to connect a signal processor/effects device to
the FX loop, you may instead then connect another instrument or
tape deck. For instance you could connect another guitar, keybo-
ards, drum machine, tape player, etc. for rehearsals or practice ses-
sions. When you use the FX RETURN as a second input channel,
the FX-MIX knob is used to balance the respective volumes of your
guitar and the other connected signal source. Another option is
open to you if you do not connect a signal processor: you can use
the loop to activate an additional MASTER volume. Proceed as fol-
lows: • Activate the FX loop.
• Dial in a separate MASTER VOLUME setting via the FX MIX pot
(to the left towards DRY = volume down, to the right towards
WET = volume up).
• You can switch back and forth between the two MASTER VOLU-
MES via the FX footswitch. If you have installed the MIDI option,
you can also activate the alternate MASTER VOLUME via a MIDI
command.
3.5 USING MIDI
Once the MSM-1 MIDI Module has been installed, you can exe-
cute the majority of the switching operations via MIDI.
Simultaneous switching of both the TUBE 50 / TUBE 100 and the
multi-effects processor is the utmost in convenience - with a
wealth of all-tube sounds.
Installing the MSM-1 MIDI Module:
NOTE: The MSM-1 Module must be installed by a qualified servi-
ce technician. The following instructions apply to repair person-
nel only.
• Unplug the mains cord and speaker cables from the amplifier.
• Remove the MIDI Module port cover plate from the rear panel
of the chassis.
• Remove the amp chassis from the wooden cabinet. For the
combo version, after unplugging the speaker cable, remove the
four retainer screws at the top of the amp. For the head version,
remove the front panel cover to access the chassis retainer scr-
ews. Make sure that you do not damage the reverb cable when
you pull the chassis out.
• Insert the included MSM-1 ribbon-cable connector plug in the
MSM-1's socket so that the color-coded wire faces the notch on
the socket. Note that the two ribbon-cable connector plugs face
away from the module in different directions. Select the plug
that allows for the shortest signal path. Ensure you do not bend
the pins when inserting the plug.
