Congratulations and thank you for
purchasing the TRIAMP all-tube guitar
amplifier. TriAmp is the world's first amp to
house three completely different all-tube
amps in one head.
Over the past forty years, thousands of amps have
appeared on the market, of which only a few have
become coveted classics. Tone quality and
response to the player's touch are the attributes
that have made these amps so uncommonly
popular, so much so that they fetch uncommonly
high prices today.
TriAmp deeply honors the past, but breaks through
its limitations. Like its classical predecessors,
TriAmp utilizes classic components exclusively,
such as vacuum tubes and resistors. But TriAmp
introduces new technologies that put these
timeless components to work in unique new ways,
offering you an absolute diversity of tone not
available from any other all-tube amp.
For the first time in amp history, TriAmp offers the
tube purist three heads in one: the past, present,
and future of all-tube tone.

TRIAMP - Manual
1.0 TRIAMP
- Three amps in a single chassis.
Three completely different all-tube amplifiers in one housing
- three totally unique worlds of authentic tone in one head this has been a seemingly impossible guitarist's dream. But
after years of intensive research and development, this
combination is now a reality in the TriAmp all-tube
amplifier. TriAmp's new and unprecedented circuitry
enabled us to integrate three individual tube amps offering
ultimate tonal quality. Each of these three amps is a dualchannel amplifier in its own right, giving you a total of six
unique basic sounds at the touch of a button.
AMP 1
The first amp is dedicated to delivering classic clean sounds.
Classic amps were originally built to meet the demand for
the cleanest, clearest tone, but creative guitarists soon
discovered that a wide-open amp had a charm unto itself.
This is exactly the type of sound that AMP 1 delivers.
CHANNEL A has a warm, round tone and when overdriven,
delivers smooth, broad-band distortion. CHANNEL B has
more of an edge to it and will bring out the harmonics in the
upper midrange even at lower GAIN settings - ideal for
single-note picking and lively arpeggios. Both channels will
of course generate a wealth of pristine clean tones at the
appropriate GAIN settings.
Note how the amp reacts to your attack when you activate
the TIGHT button - response becomes tighter, more direct
and more percussive.
AMP 2
What will strike you about the second amp is its
extraordinary dynamics at every level of distortion. This
responsiveness opens up enormous expressive possibilities
by reacting sensitively to the subtleties and nuances of
different playing styles. This amp conveys every detail of
your attack - this is as honest as an amp gets.
CHANNEL A has a wide-open, British tone with a rough and
ready character that punches through the din when you are
playing rhythm. The tone in CHANNEL B gets fatter as the
level of distortion goes up; as you play with greater sustain,
the more this amp begins to sing.
The response of AMP 2 can likewise be modified with the
TIGHT button.
AMP 3
'Truth in distortion' is a major consideration when buying an
amp. An absolute prerequisite for any top amp is that it
preserves the guitar's own characteristic sound - rather than
making all guitars sound more or less alike - and the tone
must remain well defined no matter how high you set the
gain. Only a handful of amps make the grade, and AMP 3 is
certainly a leading member of this elite club.
The lead sound in CHANNEL A is honest and direct - it
responds dynamically to your attack and the volume pot
changes of your guitar. CHANNEL A is great for aggressive
soloing and can deliver plenty of power-chord muscle
without becoming mushy. CHANNEL B delivers virtually
infinite high-gain singing sustain with loads of punchy mids
for cutting leads.
How does TriAmp produce such fundamentally different
sounds with just one power amp and a common master
section?
TriAmp's tonal potential lies primarily in its puristic tube
design. Highly advanced new switching technology
developed by Hughes & Kettner for this amp reconfigures
the multiple tube stages with each new sound you select.
This new design pulls every drop of tone out of the all-tube
circuitry, lending TriAmp incredible tonal flexibility without
any reliance on solid-state compromises. The power amp
design further supports TriAmp's vast range of tones through
the utilization of a variable presence circuit and the
application of a unique damping factor to the power stage
for each of the six basic sounds.

THE GLOBAL CURRENT ADAPTER
NOTE: Before plugging into the wall socket, make certain
the amp is set to the proper voltage for your locale. You can
read the amp's voltage setting in the Voltage Selector
window found on the back of the unit. Also check the fuse
specifications printed above the amp's power cord socket,
and ensure that the fuses you are using have the correct
value for your local current.
TriAmp can operate at AC currents of 230 volts, 115 volts or
100 volts. Use the VOLTAGE SELECTOR to adjust the
voltage accordingly (see Diagram 1):
- Press the fuse's safety latch (1) towards the window (3) with
a small screwdriver and remove it with the two fuses.
- Pull the cartridge (4) out of its socket.
- Rotate the cartridge (4) and plug it back into the socket so
the desired voltage is legible.
- Replace the previously mounted fuses (5). Make certain the
values of your fuses are identical to those required for your
local voltage. The values are specified above the amp's
power cord socket.
- Reinsert the fuse cartridge (2) with the new fuses (5).
- Before you plug into the wall socket, check again to ensure
the correct voltage rating is legible in the VOLTAGE
SELECTOR window (3).

LOOP never compromises the amp's sound quality.
NOTE: As a rule of thumb, the best method for using signal
processors is to set the output of the processor itself to
maximum effect (balance = 100%), and then mix the
processed signal with the original signal via the FX-MIX
control to avoid the sound degradation an effects device
might otherwise introduce.
Switch the FX LOOP button on the front panel to OFF if you
want to switch the FX LOOP via the STAGEBOARD or MIDI
commands.
Connecting signal processors:
- Connect the device's INPUT to the FX LOOP SEND jack
and its OUTPUT to the RETURN jack.
- Activate the FX LOOP via the FX LOOP button on the front
panel or the STAGEBOARD.
- Adapt the FX loop level to the signal processor's level, if
necessary. Press the -10 db button for effects devices like
stomp boxes that are designed for guitar signals. If the button
is not depressed, the signal level remains at standard line
level, appropriate for most rack-mounted multi-effects
processors.
- Adjust the relative volumes of the original and processed
signals via the FX MIX pot located on the front panel
(towards DRY = more original signal, towards WET = more
processed signal).
NOTE: Some signal processors cause phase cancellations
that are detrimental to the overall sound. If this is the case,
turn the FX control all the way to the right (WET). The effects
loop now operates as a conventional serial loop, i.e. the
volume relationship between the original and the processed
signal must be adjusted at the processor.
TIP 1: If you choose not to connect a signal processor or
effects device to the FX loop, you may connect another
instrument or audio source. When you use the RETURN
circuit as a second input channel in this way, the FX-MIX
knob becomes a balance control to determine the relative
volumes of the guitar signal and the other sound source.
TIP 2: Another option is open to you if you are not using a
signal processor. Use the loop, with nothing connected to it,
as a second master volume. Simply activate the FX loop and
dial in a separate master volume setting via the FX MIX pot
(to the left towards DRY = volume up, to the right towards
WET = volume down). Now use the FX LOOP on/off switch
to cut back and forth between the two master volumes.
3.0 STANDARD SETUP /
CABLE CONNECTIONS
4.0 TRIAMP OPERATION
4.1 CHANNEL SELECTION
The six basic sounds/channels of the TriAmp can be
accessed via DSS (Direct Sound Switching). Simply press the
appropriate CHANNEL SELECTOR switch.
This applies to the CHANNEL SELECTOR switches located
on the front panel as well as those on the STAGEBOARD.
You can also execute switching functions via MIDI using the
MSM 1 MIDI Module (refer to Section 4.4).
If you want to use an external MIDI switcher, you will need
to make an adapter cable that accesses the Stageboard jack,
wiring it according to the pin assignments shown in Diagram
5. Channel selection is executed via momentary contact; FX
LOOP activation is executed by switching, namely by
applying pin 8 to pin 5 (ground).
Stageboard jack pin assignments:
4.2 TRIAMP AND SIGNAL PROCESSORS
TriAmp is equipped with a parallel effects loop. The
processed signal is mixed with the internal preamp's original
signal in such a way that the original signal remains audible
even during the brief lags caused by multi-effects processor
switching. The FX-MIX knob controls the dry/wet mix.
The passive nature of the FX MIX guarantees that the original
signal is not sent through any solid-state circuitry. When the
FX LOOP is deactivated, the buffer stage for the effects side
is switched off via a relay, thereby ensuring that the FX
